1 Zabbix客户端

概述

这些检查与Zabbix代理进行通信实现数据的采集。

被动和主动 两种agent模式. 在配置监控项时,你可以选择所需的类型:

  • Zabbix 客户端 - 被动模式,Zabbix Server向Agent索要数据
  • Zabbix 客户端 (主动式) - 主动模式,Agent主动上报数据给Zabbix Server

支持的监控项key

下表提供了可用的Zabbix代理监控项键值的详细信息。

请参考:

** 必填和可选参数 **

没有尖括号的参数是强制性的。标有尖括号 < > 的参数是可选的。

键值
描述 * 返回值** **参数 * 注释
agent.hostname
客户端主机名. Strin 从配置文件 回客户端主机名的实际值。
agent.ping
客户端可用性检查 Nothing - 不可用

1 - 可用
使用**nodata )**触发器函数检查主机不可用性。
agent.version
Zabbix 客户端的版本 字符串 例如返回值:
<1.8.2
kernel.maxfiles
系统支持的打开文件的最大数量 整数
kernel.maxproc
系统支持的最大进程数 整数
log[file,<regexp>,<encoding>,<maxlines>,<mode>,<output>,<maxdelay>]
日志文件监控。 Log **file * - 日志文件完整路径和名称  监控项必须定义为[主动检查](/zregexp - 描述所需模式的正则表达式  如果文件丢失或权限不允encoding - 编码 标识符 
maxlines - Agent将发送到Zabbix服务器或代理的每秒最大行数。此参数覆盖zabbix_agentd.conf中的“MaxLinesPerSecond”值  如果output 为空 - 返回包含匹配文本的mode - 可能的值: 
all (默认值), skip - 跳过处理历史的数据(仅影响新创建的监控项)。  在客户端端使用output 参数提取内容。
output - 可选项,输出格式模板。 \0转义序列替换为匹配的文本,而\N(其中N = 1 ... 9)转义序列被替换为第N个匹配组(如果N超过捕获组的数量,则为空字符串)。 
maxdelay - 最大延迟(秒)。 类型:float。 值:0-(默认)不忽略日志文件行; > 0.0-忽略旧行,以便在“maxdelay”秒内获取最近分析的行。使用前请阅读 maxdelay注释! 示例:
/manual/appendix/items/activepassive#active_checks).
访问,则监控项不受支持。
行。请注意,除“Result为TRUE”之外的所有全局正则表达式类型始终返回整个匹配行,并忽略output 参数。
=> log[/var/log/syslog]
=> log[/var/log/syslog,error]
=> log[/home/zabbix/logs/logfile,,,100]

使用output参数从日志记录中提取数字的示例:
log[/app1/app.log,"task run [0-9.]+ sec, processed ([0-9]+) records, [0-9]+ errors",,,,\1]- will match a log record "2015-11-13 10:08:26 task run 6.08 sec, processed 6080 records, 0 errors" and send only number 6080 to server. Because a number is being sent, the "Type of information" for this log item can be changed from "Log" to "Numeric (unsigned)" and the value can be used in graphs, triggers etc.

在发送到服务器之前使用output参数重写日志记录的示例:
log[/app1/app.log,"([0-9 :-]+) task run ([0-9.]+) sec, processed ([0-9]+) records, ([0-9]+) errors",,,,"\1 RECORDS: \3, ERRORS: \4, DURATION: \2"]- will match a log record "2015-11-13 10:08:26 task run 6.08 sec, processed 6080 records, 0 errors" and send a modified record "2015-11-13 10:08:26 RECORDS: 6080, ERRORS: 0, DURATION: 6.08" to server.

mode 参数从Zabbix 2.0之后被支持。
output 从Zabbix 2.2之后被支持
maxdelay参数从Zabbix 3.2以后被支持。

更多信息请参考日志文件监控.

t为TRUE”之外的所有全局正则表达式类型始终返回整个匹配行,并忽略输出参数。
/home/zabbix/logs/^logfile[0-9]{1,3}$",,,100] → 将返回一个文件类似"logfile1" (不会匹配".logfile1")
_[0-9]{1,3}$","pattern_to_match","UTF-8",100] → 将从文件收集信息例如 "logfile_abc_1" 或者 "logfile__001".

使用output参数从日志记录中提取数字的示例:
logrt[/app1/^test.*log$,"task run [0-9.]+ sec, processed ([0-9]+) records, [0-9]+ errors",,,,\1]- will match a log record "2015-11-13 10:08:26 task run 6.08 sec, processed 6080 records, 0 errors" and send only number 6080 to server. 由于正在发送一个数字,因此该日志项的“信息类型”可以从“日志”更改为“数字(无正负)”,并且该值可以用于图形,触发器等。

在发送到服务器之前使用output参数重写日志记录的示例:*
logrt[/app1/^test.*log$,"([0-9 :-]+) task run ([0-9.]+) sec, processed ([0-9]+) records, ([0-9]+) errors",,,,"\1 RECORDS: \3, ERRORS: \4, DURATION: \2"]- will match a log record "2015-11-13 10:08:26 task run 6.08 sec, processed 6080 records, 0 errors" and send a modified record "2015-11-13 10:08:26 RECORDS: 6080, ERRORS: 0, DURATION: 6.08" to server.

mode 参数从Zabbix 2.0以后开始支持。

vfs.dev.read[<device>,<type>,<mode>]
磁盘读取统计信息。 整数 - ty|esectors, operations, bytes  device
Float - typesps, ops, bps
磁盘设备 (默认为 all)  不同操作系统的“类型”参数的默认值:type - 可能的值: sectors, operations, bytes, sps, ops, bps  AIX须指定此参数,因为各种操作系统的默认值不同。  FreeBSD - bps

旧名字: io[*]
vfs.dir.count[dir,<regex_incl>,<regex_excl>,<types_incl>,<types_excl>,<max_depth>,<min_size>,<max_size>,<min_age>,<max_age>]
目录条目计数. 整数 dir - 目录的绝对路径  例如%APP_HOME%,regex_incl - 正则表达式,描述包含的文件,目录和符号链接名称模式(包括所有文件,目录和符号链接,如果为空;空字符串是默认值) 
regex_excl - 正则表达式描述文件,目录和符号链接名称模式以排除(不排除任何如果为空;空字符串是默认值)  隐藏目录 "." and ".." 不会被计算。
types_incl - 要计算的一组目录条目类型,可能的值: 
file - 常规文件, dir - 子目录, sym - 符号链接, sock - 套接字, bdev - 块设备, cdev - 字符设备, fifo- FIFO, dev- "bdev,cdev"的同义词, all- 所有上述类型,即 "file,dir,sym,sock,bdev,cdev,fifo". 如果参数为空,all为默认值。 必须用逗号分隔多个类型,并用引号“”括起整个集合。  目录遍历不遵循符号链接。
types_excl - 要计数的一组目录条目类型,与<types_incl>相同的值和语法。 如果某些条目类型同时位于<types_incl>和<types_excl>中,则不计算此类型的目录条目。 
max_depth - 遍历的子目录的最大深度。 -1 (默认) - 无限制, 0 - 不涉及子目录  在Windows目录中,将跳过符号链接,并且min_size - 要计算的文件最小大小。小于此的文件将不计算在内。 该值以字节为单位。 内存后缀 可以被使用。 
max_size - 要计算的文件的最大大小。 大于此的文件将不计算在内。 该值以字节为单位。内存后缀 可以被使用。  regex_inclregex_excl 是 [Perl兼容的正则表达式min_age - 要计算的目录条目的最小创建时间。 最新编辑的条目不会被计算在内。 整数值以秒为单位。时间后缀 可以被使用。 
max_age - 要计算的目录条目的最大创建时间。 很久之前编辑的条目将不计算在内(修改时间)。 整数值以秒为单位。时间后缀 可以被使用。 执行时间将受到默认超时值3秒的限制(代理配置文件中的“超时”参数)。 由于大型目录遍历可能需要更长时间,因此不会
$HOME 和 %TEMP% 子类的环境变量是不支持的。
对硬链接计数一次。
(https://en.wikipedia.org/wiki/Perl_Compatible_Regular_Expressions) (PCRE). regex_inclregex_excl在计算条目大小时都应用于文件和目录,但在选择遍历的子目录时会被忽略(如果regex_incl是“(?i)^.+\.zip$”并且未设置max_depth,则将遍历所有子目录,但只会计算zip类型的文件)。 如果文件名与regex_inclregex_excl匹配,则不会计算此文件。
回任何数据,并且该项目将标记为“不支持”。 部分计数不会被退回。

按大小过滤时,只有常规文件具有有意义的大小。 在Linux和BSD下,目录也具有非零大小(通常为几Kb)。 设备的大小为零,例如 /dev/sda1 的大小不反映相应的分区大小。 因此,当使用<min_size><max_size>参数时,建议将<types_incl>指定为 /dev/sda1 ,以避免意外。

例子:
? vfs.dir.count[/dev] - 监视/dev中的设备数量(Linux)
? vfs.dir.count["C:\Users\ADMINI~1\AppData\Local\Temp"] - 监视临时目录中的文件数(Windows)

Zabbix 4.0.0.后支持该功能
vfs.dir.size[dir,<regex_incl>,<regex_excl>,<mode>,<max_depth>]
目录大小(以字节为单位)。 整数 dir - 目录的绝 路径  仅计算具有zabbix用户读取权限的目录。regex_incl - 正则表达式描述包含的文件名模式(如果为空则包括所有文件;空字符串是默认值) 
regex_excl - 正则表达式描述用于排除的文件名模式(如果为空不排除任何文件;空字符串是默认值)  在Windows上,将跳过任何符号链接,并且仅将硬链接考虑在内。
mode - 可能的值:  \
apparent (默认) - 获得明确的文件大小,而不是磁盘利用率(作为 du -sb dir), disk - 获取磁盘使用情况 (作为 du -s -B1 dir). 和du命令不同,vfs.dir.size 监控项在计算目录大小时会将隐藏的文件记录帐户 (作为 du -sb .[^.]* * 在 dir内). 
max_depth - 要遍历的子目录的最大深度。 -1 (默认) - 无限, 0 - 不会遍历到子目录。  示例:
<对于大型目录或慢速驱动器,由于客户端服务端/代理 配置文件中的超时设置,此项可能会超时。 根据需要增加超时值。
? vfs.dir.size[/tmp,log] - 计算/tmp中包含“log”的所有文件的大小
? vfs.dir.size[/tmp,log,^.+\.old$] - 计算/tmp中包含“log”的所有文件的大小,不包括包含'.old'的文件

文件大小限制取决于大文件支持
vfs.file.cksum[file]
文件checksum校验,由UNIX cksum算法计算实现。 整型 file - 文件全 径 示例:
<=> vfs.file.cksum[/etc/passwd]

返回值示例:
1938292000

旧名字: cksum

文件大小限制取决于大文件支持
vfs.file.contents[file,<encoding>]
检索文件的内容。 文本 file 文件全路径  如果文件为空或仅包含LF/Cencoding - 编码页 标识符

2 - Zabbix agent 2

Supported since Zabbix 5.4.8.
agent.version
Version of Zabbix agent. String Example of returned value:
1.8.2
kernel.maxfiles

log[file,<regexp>,<encoding>,<maxlines>,<mode>,<output>,<maxdelay>,<options>,<persistent_dir>]
Log file monitoring. Log file - full path and name of log file
regexp - regular expression describing the required pattern
encoding - code page identifier
maxlines - maximum number of new lines per second the agent will send to Zabbix server or proxy. This parameter overrides the value of 'MaxLinesPerSecond' in zabbix_agentd.conf
mode (since version 2.0)- possible values:
all (default), skip - skip processing of older data (affects only newly created items).
output (since version 2.2) - an optional output formatting template. The \0 escape sequence is replaced with the matched part of text (from the first character where match begins until the character where match ends) while an \N (where N=1...9) escape sequence is replaced with Nth matched group (or an empty string if the N exceeds the number of captured groups).
maxdelay (since version 3.2) - maximum delay in seconds. Type: float. Values: 0 - (default) never ignore log file lines; > 0.0 - ignore older lines in order to get the most recent lines analyzed within "maxdelay" seconds. Read the maxdelay notes before using it!
options (since version 4.4.7) - additional options:
mtime-noreread - non-unique records, reread only if the file size changes (ignore modification time change). (This parameter is deprecated since 5.0.2, because now mtime is ignored.
persistent_dir (since versions 5.0.18, 5.4.9, only in zabbix_agentd on Unix systems; not supported in Agent2) - absolute pathname of directory where to store persistent files. See also additional notes on persistent files.
The item must be configured as an active check.
If file is missing or permissions do not allow access, item turns unsupported.

If output is left empty - the whole line containing the matched text is returned. Note that all global regular expression types except 'Result is TRUE' always return the whole matched line and the output parameter is ignored.

Content extraction using the output parameter takes place on the agent.

Examples:
=> log[/var/log/syslog]
=> log[/var/log/syslog,error]
=> log[/home/zabbix/logs/logfile,,,100]

Using output parameter for extracting a number from log record:
=> log[/app1/app.log,"task run [0-9.]+ sec, processed ([0-9]+) records, [0-9]+ errors",,,,\1] → will match a log record "2015-11-13 10:08:26 task run 6.08 sec, processed 6080 records, 0 errors" and send only '6080' to server. Because a numeric value is being sent, the "Type of information" for this item can be set to "Numeric (unsigned)" and the value can be used in graphs, triggers etc.

Using output parameter for rewriting log record before sending to server:
=> log[/app1/app.log,"([0-9 :-]+) task run ([0-9.]+) sec, processed ([0-9]+) records, ([0-9]+) errors",,,,"\1 RECORDS: \3, ERRORS: \4, DURATION: \2"] → will match a log record "2015-11-13 10:08:26 task run 6.08 sec, processed 6080 records, 0 errors" and send a modified record "2015-11-13 10:08:26 RECORDS: 6080, ERRORS: 0, DURATION: 6.08" to server.

See also additional information on log monitoring.

Count of matched lines in log file monitoring. Integer file - full path and name of log file
regexp - regular expression describing the required pattern
encoding - code page identifier
maxproclines - maximum number of new lines per second the agent will analyze (cannot exceed 10000). Default value is 10*'MaxLinesPerSecond' in zabbix_agentd.conf.
mode - possible values:
all (default), skip - skip processing of older data (affects only newly created items).
maxdelay - maximum delay in seconds. Type: float. Values: 0 - (default) never ignore log file lines; > 0.0 - ignore older lines in order to get the most recent lines analyzed within "maxdelay" seconds. Read the maxdelay notes before using it!
options (since version 4.4.7) - additional options:
mtime-noreread - non-unique records, reread only if the file size changes (ignore modification time change). (This parameter is deprecated since 5.0.2, because now mtime is ignored.)
persistent_dir (since versions 5.0.18, 5.4.9, only in zabbix_agentd on Unix systems; not supported in Agent2) - absolute pathname of directory where to store persistent files. See also additional notes on persistent files.
The item must be configured as an active check.
If file is missing or permissions do not allow access, item turns unsupported.

See also additional information on log monitoring.

This item is not supported for Windows Event Log.

Supported since Zabbix 3.2.0.
logrt[file_regexp,<regexp>,<encoding>,<maxlines>,<mode>,<output>,<maxdelay>,<options>,<persistent_dir>]
Log file monitoring with log rotation support. Log file_regexp - absolute path to file and the file name described by a regular expression. Note that only the file name is a regular expression
regexp - regular expression describing the required content pattern
encoding - code page identifier
maxlines - maximum number of new lines per second the agent will send to Zabbix server or proxy. This parameter overrides the value of 'MaxLinesPerSecond' in zabbix_agentd.conf
mode (since version 2.0) - possible values:
all (default), skip - skip processing of older data (affects only newly created items).
output (since version 2.2) - an optional output formatting template. The \0 escape sequence is replaced with the matched part of text (from the first character where match begins until the character where match ends) while an \N (where N=1...9) escape sequence is replaced with Nth matched group (or an empty string if the N exceeds the number of captured groups).
maxdelay (since version 3.2) - maximum delay in seconds. Type: float. Values: 0 - (default) never ignore log file lines; > 0.0 - ignore older lines in order to get the most recent lines analyzed within "maxdelay" seconds. Read the maxdelay notes before using it!
options (since version 4.0; mtime-reread, mtime-noreread options since 4.4.7) - type of log file rotation and other options. Possible values:
rotate (default),
copytruncate - note that copytruncate cannot be used together with maxdelay. In this case maxdelay must be 0 or not specified; see copytruncate notes,
mtime-reread - non-unique records, reread if modification time or size changes (default),
mtime-noreread - non-unique records, reread only if the size changes (ignore modification time change).
persistent_dir (since versions 5.0.18, 5.4.9, only in zabbix_agentd on Unix systems; not supported in Agent2) - absolute pathname of directory where to store persistent files. See also additional notes on persistent files.
The item must be configured as an active check.
Log rotation is based on the last modification time of files.

Note that logrt is designed to work with one currently active log file, with several other matching inactive files rotated. If, for example, a directory has many active log files, a separate logrt item should be created for each one. Otherwise if one logrt item picks up too many files it may lead to exhausted memory and a crash of monitoring.

If output is left empty - the whole line containing the matched text is returned. Note that all global regular expression types except 'Result is TRUE' always return the whole matched line and the output parameter is ignored.

Content extraction using the output parameter takes place on the agent.

Examples:
=> logrt["/home/zabbix/logs/^logfile[0-9]{1,3}$",,,100] → will match a file like "logfile1" (will not match ".logfile1")
=> logrt["/home/user/^logfile_.*_[0-9]{1,3}$","pattern_to_match","UTF-8",100] → will collect data from files such "logfile_abc_1" or "logfile__001".

Using output parameter for extracting a number from log record:
=> logrt[/app1/^test.*log$,"task run [0-9.]+ sec, processed ([0-9]+) records, [0-9]+ errors",,,,\1] → will match a log record "2015-11-13 10:08:26 task run 6.08 sec, processed 6080 records, 0 errors" and send only '6080' to server. Because a numeric value is being sent, the "Type of information" for this item can be set to "Numeric (unsigned)" and the value can be used in graphs, triggers etc.

Using output parameter for rewriting log record before sending to server:
=> logrt[/app1/^test.*log$,"([0-9 :-]+) task run ([0-9.]+) sec, processed ([0-9]+) records, ([0-9]+) errors",,,,"\1 RECORDS: \3, ERRORS: \4, DURATION: \2"] → will match a log record "2015-11-13 10:08:26 task run 6.08 sec, processed 6080 records, 0 errors" and send a modified record "2015-11-13 10:08:26 RECORDS: 6080, ERRORS: 0, DURATION: 6.08" to server.

The returned value is based on single CPU core utilization percentage. For example CPU utilization of a process fully using two cores is 200%.

The process CPU utilization data is gathered by a collector which supports the maximum of 1024 unique (by name, user and command line) queries. Queries not accessed during the last 24 hours are removed from the collector.

Note that when setting the zone parameter to current (or default) in case the agent has been compiled on a Solaris without zone support, but running on a newer Solaris where zones are supported, then the agent will return NOTSUPPORTED (the agent cannot limit results to only the current zone). However, all is supported in this case.

=> proc.mem[,oracle,max,oracleZABBIX] → memory used by the most memory-hungry process running under oracle having oracleZABBIX in its command line

Note: When several processes use shared memory, the sum of memory used by processes may result in large, unrealistic values.

See notes on selecting processes with name and cmdline parameters (Linux-specific).

When this item is invoked from the command line and contains a command line parameter (e.g. using the agent test mode: zabbix_agentd -t proc.mem[,,,apache2]), one extra process will be counted, as the agent will count itself.

On Windows, only the name and user parameters are supported.

When this item is invoked from the command line and contains a command line parameter (e.g. using the agent test mode: zabbix_agentd -t proc.num[,,,apache2]), one extra process will be counted, as the agent will count itself.

Note that when setting the zone parameter to current (or default) in case the agent has been compiled on a Solaris without zone support, but running on a newer Solaris where zones are supported, then the agent will return NOTSUPPORTED (the agent cannot limit results to only the current zone). However, all is supported in this case.

sps, ops and bps on supported platforms used to be limited to 8 devices (7 individual and one all). Since Zabbix 2.0.1 this limit is 1024 devices (1023 individual and one for all).
vfs.dev.write[<device>,<type>,<mode>]
Disk write statistics. Integer - with type in sectors, operations, bytes

Float - with type in sps, ops, bps

Note: if using an update interval of three hours or more2, will always return '0'
device - disk device (default is all 3)
type - possible values: sectors, operations, bytes, sps, ops, bps
Note that 'type' parameter support and defaults depend on the platform. See platform-specific details.
sps, ops, bps stand for: sectors, operations, bytes per second, respectively.
mode - possible values: avg1 (one-minute average, default), avg5, avg15.
This parameter is supported only with type in: sps, ops, bps.
You may use relative device names (for example, sda) as well as an optional /dev/ prefix (for example, /dev/sda).

LVM logical volumes are supported.

Default values of 'type' parameter for different OSes:
AIX - operations
FreeBSD - bps
Linux - sps
OpenBSD - operations
Solaris - bytes

Example:
=> vfs.dev.write[,operations]

sps, ops and bps on supported platforms used to be limited to 8 devices (7 individual and one all). Since Zabbix 2.0.1 this limit is 1024 (1023 individual and one for all).
vfs.dir.count[dir,<regex_incl>,<regex_excl>,<types_incl>,<types_excl>,<max_depth>,<min_size>,<max_size>,<min_age>,<max_age>,<regex_excl_dir>]
Directory entry count. Integer dir - absolute path to directory
regex_incl - regular expression describing the name pattern of the entity (file, directory, symbolic link) to include; include all if empty (default value)
regex_excl - regular expression describing the name pattern of the entity (file, directory, symbolic link) to exclude; don't exclude any if empty (default value)
types_incl - directory entry types to count, possible values:
file - regular file, dir - subdirectory, sym - symbolic link, sock - socket, bdev - block device, cdev - character device, fifo - FIFO, dev - synonymous with "bdev,cdev", all - all types (default), i.e. "file,dir,sym,sock,bdev,cdev,fifo". Multiple types must be separated with comma and quoted.
types_excl - directory entry types (see <types_incl>) to NOT count. If some entry type is in both <types_incl> and <types_excl>, directory entries of this type are NOT counted.
max_depth - maximum depth of subdirectories to traverse. -1 (default) - unlimited, 0 - no descending into subdirectories.
min_size - minimum size (in bytes) for file to be counted. Smaller files will not be counted. Memory suffixes can be used.
max_size - maximum size (in bytes) for file to be counted. Larger files will not be counted. Memory suffixes can be used.
min_age - minimum age (in seconds) of directory entry to be counted. More recent entries will not be counted. Time suffixes can be used.
max_age - maximum age (in seconds) of directory entry to be counted. Entries so old and older will not be counted (modification time). Time suffixes can be used.
regex_excl_dir - regular expression describing the name pattern of the directory to exclude. All content of the directory will be excluded (in contrast to regex_excl)
Environment variables, e.g. %APP_HOME%, $HOME and %TEMP% are not supported.

Pseudo-directories "." and ".." are never counted.

Symbolic links are never followed for directory traversal.

On Windows, directory symlinks are skipped and hard links are counted only once.

Both regex_incl and regex_excl are being applied to files and directories when calculating entry size, but are ignored when picking subdirectories to traverse (if regex_incl is “(?i)^.+\.zip$” and max_depth is not set, then all subdirectories will be traversed, but only files of type zip will be counted).

Execution time is limited by the default timeout value in agent configuration (3 sec). Since large directory traversal may take longer than that, no data will be returned and the item will turn unsupported. Partial count will not be returned.

When filtering by size, only regular files have meaningful sizes. Under Linux and BSD, directories also have non-zero sizes (a few Kb typically). Devices have zero sizes, e.g. the size of /dev/sda1 does not reflect the respective partition size. Therefore, when using <min_size> and <max_size>, it is advisable to specify <types_incl> as "file", to avoid surprises.

Examples:
⇒ vfs.dir.count[/dev] - monitors number of devices in /dev (Linux)
⇒ vfs.dir.count["C:\Users\ADMINI~1\AppData\Local\Temp"] - monitors number of files in temporary directory (Windows)

Supported since Zabbix 4.0.0.
vfs.dir.size[dir,<regex_incl>,<regex_excl>,<mode>,<max_depth>,<regex_excl_dir>]
Directory size (in bytes). Integer dir - absolute path to directory
regex_incl - regular expression describing the name pattern of the entity (file, directory, symbolic link) to include; include all if empty (default value)
regex_excl - regular expression describing the name pattern of the entity (file, directory, symbolic link) to exclude; don't exclude any if empty (default value)
mode - possible values:
apparent (default) - gets apparent file sizes rather than disk usage (acts as du -sb dir), disk - gets disk usage (acts as du -s -B1 dir). Unlike du command, vfs.dir.size item takes hidden files in account when calculating directory size (acts as du -sb .[^.]* * within dir).
max_depth - maximum depth of subdirectories to traverse. -1 (default) - unlimited, 0 - no descending into subdirectories.
regex_excl_dir - regular expression describing the name pattern of the directory to exclude. All content of the directory will be excluded (in contrast to regex_excl)
Only directories with at least read permission for zabbix user are calculated.

On Windows any symlink is skipped and hard links are taken into account only once.

With large directories or slow drives this item may time out due to the Timeout setting in agent and server/proxy configuration files. Increase the timeout values as necessary.

Examples:
⇒ vfs.dir.size[/tmp,log] - calculates size of all files in /tmp which contain 'log'
⇒ vfs.dir.size[/tmp,log,^.+\.old$] - calculates size of all files in /tmp which contain 'log', excluding files containing '.old'

The file size limit depends on large file support.

Supported since Zabbix 3.4.0.

Byte order mark (BOM) is excluded from the output.

Example:
=> vfs.file.contents[/etc/passwd]

This item is limited to files no larger than 64 Kbytes.

Supported since Zabbix agent version 2.0.
vfs.file.exists[file,<types_incl>,<types_excl>]
Checks if file exists. 0 - not found

1 - file of the specified type exists
file - full path to file
types_incl - list of file types to include, possible values: file (regular file, default (if types_excl is not set)), dir (directory), sym (symbolic link), sock (socket), bdev (block device), cdev (character device), fifo (FIFO), dev (synonymous with "bdev,cdev"), all (all mentioned types, default if types_excl is set).
types_excl - list of file types to exclude, see types_incl for possible values (by default no types are excluded)
Multiple types must be separated with a comma and the entire set enclosed in quotes "".
On Windows the double quotes have to be backslash '\' escaped and the whole item key enclosed in double quotes when using the command line utility for calling zabbix_get.exe or agent2.

If the same type is in both <types_incl> and <types_excl>, files of this type are excluded.

Examples:
=> vfs.file.exists[/tmp/application.pid]
=> vfs.file.exists[/tmp/application.pid,"file,dir,sym"]
=> vfs.file.exists[/tmp/application_dir,dir]

The file size limit depends on large file support.

Note that the item may turn unsupported on Windows if a directory is searched within a non-existing directory, e.g. vfs.file.exists[C:\no\dir,dir] (where 'no' does not exist).
vfs.file.md5sum[file]

可用的编码

encoding 参数用于指定处理相应监控项检查的编码,以便获取的数据不会被破坏。 有关支持的编码(代码页标识符)的列表,请参阅相应的文档,例如libiconv(GNU Project)或Microsoft Windows SDK文档“代码页标识符”的文档。

如果传递空encoding,则默认使用UTF-8(用于较新的Unix/Linux发行版的默认语言环境,请参阅系统设置)或使用具有系统特定扩展名(Windows)的ANSI。

关于监控项的一些疑难问题

  1. 如果与passive agent一起使用,服务器配置中的 超时值 可能需要高于代理配置文件中的 超时值 。 否则,该监控项可能无法获取任何值,因为服务器请求代理程序首先超时。

Troubleshooting agent items

  • If used with the passive agent, Timeout value in server configuration may need to be higher than Timeout in the agent configuration file. Otherwise the item may not get any value because the server request to agent timed out first.

Mandatory and optional parameters

Parameters without angle brackets are mandatory. Parameters marked with angle brackets < > are optional.

Usage with command-line utilities

Note that when testing or using item keys with zabbix_agentd or zabbix_get from the command line you should consider shell syntax too.

For example, if a certain parameter of the key has to be enclosed in double quotes you have to explicitly escape double quotes, otherwise they will be trimmed by the shell as special characters and will not be passed to the Zabbix utility.

Examples:

$ zabbix_agentd -t 'vfs.dir.count[/var/log,,,"file,dir",,0]'
       
       $ zabbix_agentd -t vfs.dir.count[/var/log,,,\"file,dir\",,0]
