2 Zabbix Proxy

Zabbix proxy is a process which collects performance and availability data from one or more monitored devices and sends the information to a Zabbix server. Zabbix proxy can be started by:

shell> cd sbin
shell> ./zabbix_proxy

Zabbix proxy runs as a daemon process.

Zabbix proxy accepts the following command line parameters:

-c --config <file>              absolute path to the configuration file
-R --runtime-control <option>   perform administrative functions
-h --help                       give this help
-V --version                    display version number

-R or --runtime-control option is supported since Zabbix 1.8.6.
Runtime control is not supported on OpenBSD and NetBSD.

In order to get more help run:

shell> zabbix_proxy -h

Example of command line parameters:

shell> zabbix_proxy -c /usr/local/etc/zabbix_proxy.conf
shell> zabbix_proxy --help
shell> zabbix_proxy -V

Runtime control

Runtime control options:

OptionDescription
config_cache_reloadReload configuration cache. Ignored if cache is being currently loaded.
Active Zabbix proxy will connect to the Zabbix server and request configuration data.

Example of using runtime control to reload the proxy configuration cache:

shell> zabbix_proxy -c /usr/local/etc/zabbix_proxy.conf -R config_cache_reload

Configuration file

The configuration file contains parameters for zabbix_proxy. The file must exist and it should have read permissions for user 'zabbix'. Supported parameters:

ParameterMandatoryRangeDefaultDescription
CacheSize no 128K-1G 8M Size of configuration cache, in bytes.
Shared memory size, for storing hosts and items data.
ConfigFrequency no 1-604800 3600 How often proxy retrieves configuration data from Zabbix Server in seconds.
For a proxy in the passive mode this parameter will be ignored.
DBHost no Based on the underlying library implementation used. Database host name.
If set to localhost, socket is used for MySQL.
DBName yes Database name.
For SQLite3 path to database file must be provided. DBUser and DBPassword are ignored.
DBPassword no Database password. Ignored for SQLite.
Comment this line if no password is used.
DBSocket no 3306 Path to MySQL socket.
Database port when not using local socket. Ignored for SQLite.
DBUser Database user. Ignored for SQLite.
DataSenderFrequency no 1-3600 1 Proxy will send collected data to the Server every N seconds.
DebugLevel no 0-4 3 Specifies debug level
0 - no debug
1 - critical information
2 - error information
3 - warnings
4 - for debugging (produces lots of information)
DisableHousekeeping no 0-1 0 If set to 1, disables housekeeping.
ExternalScripts no /etc/zabbix/externalscripts Location of external scripts
Fping6Location no /usr/sbin/fping6 Location of fping6.
Make sure that fping6 binary has root ownership and SUID flag set.
Make empty (“Fping6Location=”) if your fping utility is capable to process IPv6 addresses.
FpingLocation no /usr/sbin/fping Location of fping.
Make sure that fping binary has root ownership and SUID flag set!
HeartbeatFrequency no 0-3600 60 Frequency of heartbeat messages in seconds.
Used for monitoring availability of Proxy on server side.
0 - heartbeat messages disabled.
For a proxy in the passive mode this parameter will be ignored.
HistoryCacheSize no 128K-1G 8M Size of history cache, in bytes.
Shared memory size for storing history data.
HistoryTextCacheSize no 128K-1G 16M Size of text history cache, in bytes.
Shared memory size for storing character, text or log history data.
Hostname no Set by HostnameItem Unique, case sensitive Proxy name. Make sure the Proxy name is known to the server!
Allowed characters: alphanumeric, '.', ' ', '_' and '-'.
Maximum length: 64
HostnameItem no system.hostname Item used for setting Hostname if it is undefined (this will be run on the proxy similarly as on an agent).
Does not support UserParameters, performance counters or aliases, but does support system.run[].

Ignored if Hostname is set.

This option is supported in version 1.8.6 and higher.
HousekeepingFrequency no 1-24 1 How often Zabbix will perform housekeeping procedure (in hours).
Housekeeping is removing unnecessary information from history, alert, and alarms tables.
Note: To prevent housekeeper from being overloaded (for example, when history and trend periods are greatly reduced), no more than 4xHousekeepingFrequency hours of outdated history are deleted in one housekeeping cycle, for each item. Thus, if HousekeepingFrequency is 1, no more than 4 hours of outdated history (starting from the oldest entry) will be deleted per cycle.
Include no You may include individual files or all files in a directory in the configuration file. See special notes about limitations.
ListenIP no 0.0.0.0 List of comma delimited IP addresses that the trapper should listen on.
Trapper will listen on all network interfaces if this parameter is missing.
Multiple IP addresses are supported in version 1.8.3 and higher.
ListenPort no 1024-32767 10051 Listen port for trapper.
LogFileSize no 0-1024 1 Maximum size of log file in MB.
0 - disable automatic log rotation.
LogFile no Name of log file.
If not set, syslog is used.
LogSlowQueries no 0-3600000 0 How long a database query may take before being logged (in milliseconds).
0 - don't log slow queries.
This option becomes enabled starting with DebugLevel=3.
This option is supported in version 1.8.2 and higher.
PidFile no /tmp/zabbix_proxy.pid Name of PID file.
ProxyLocalBuffer no 0-720 0 Proxy will keep data locally for N hours.
This parameter may be used if local data will be used by third party applications.

0 - proxy in the active mode
1 - proxy in the passive mode
This option is supported in version 1.8.3 and higher.

Older data will be lost.
SSHKeyLocation no Location of public and private keys for SSH checks
ServerPort no 1024-32767 10051 Port of Zabbix trapper on Zabbix server.
For a proxy in the passive mode this parameter will be ignored.
Server yes IP address (or hostname) of Zabbix server.

For a proxy in the passive mode this parameter will be ignored.
