2 Zabbix proxy

The default values reflect daemon defaults, not the values in the shipped configuration files.

The parameters supported in a Zabbix proxy configuration file:

ParameterMandatoryRangeDefaultDescription
AllowRoot no 0 Allow the proxy to run as 'root'. If disabled and the proxy is started by 'root', the proxy will try to switch to the 'zabbix' user instead. Has no effect if started under a regular user.
0 - do not allow
1 - allow
This parameter is supported since Zabbix 2.2.0.
CacheSize no 128K-8G 8M Size of configuration cache, in bytes.
Shared memory size, for storing host and item data.
Upper limit used to be 2GB before Zabbix 2.2.3.
ConfigFrequency no 1-604800 3600 How often proxy retrieves configuration data from Zabbix server in seconds.
Active proxy parameter. Ignored for passive proxies (see ProxyMode parameter).
DBHost no localhost Database host name.
In case of MySQL localhost or empty string results in using a socket. In case of PostgreSQL
only empty string results in attempt to use socket.
DBName yes Database name or path to database file for SQLite3 (multi-process architecture of Zabbix does not allow to use in-memory database, e.g. :memory:, file::memory:?cache=shared or file:memdb1?mode=memory&cache=shared).

Warning: Do not attempt to use the same database Zabbix server is using.
DBPassword no Database password. Ignored for SQLite.
Comment this line if no password is used.
DBSchema no Schema name. Used for IBM DB2 and PostgreSQL.
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.
Active proxy parameter. Ignored for passive proxies (see ProxyMode parameter).
DebugLevel no 0-5 3 Specifies debug level:
0 - basic information about starting and stopping of Zabbix processes
1 - critical information
2 - error information
3 - warnings
4 - for debugging (produces lots of information)
5 - extended debugging (produces even more information)
EnableRemoteCommands no 0 Whether remote commands from Zabbix server are allowed.
0 - not allowed
1 - allowed
This parameter is supported since Zabbix 3.4.0.
ExternalScripts no /usr/local/share/zabbix/externalscripts Location of external scripts (depends on compile-time installation variable datadir).
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.
Active proxy parameter. Ignored for passive proxies (see ProxyMode parameter).
HistoryCacheSize no 128K-2G 16M Size of history cache, in bytes.
Shared memory size for storing history data.
HistoryIndexCacheSize no 128K-2G 4M Size of history index cache, in bytes.
Shared memory size for indexing history data stored in history cache.
The index cache size needs roughly 100 bytes to cache one item.
This parameter is supported since Zabbix 3.0.0.
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 parameter is supported since Zabbix 1.8.6.
HousekeepingFrequency no 0-24 1 How often Zabbix will perform housekeeping procedure (in hours).
Housekeeping is removing outdated information from the database.
Note: To prevent housekeeper from being overloaded (for example, when configuration parameters ProxyLocalBuffer or ProxyOfflineBuffer are greatly reduced), no more than 4 times HousekeepingFrequency hours of outdated information are deleted in one housekeeping cycle. Thus, if HousekeepingFrequency is 1, no more than 4 hours of outdated information (starting from the oldest entry) will be deleted per cycle.
Note: To lower load on proxy startup housekeeping is postponed for 30 minutes after proxy start. Thus, if HousekeepingFrequency is 1, the very first housekeeping procedure after proxy start will run after 30 minutes, and will repeat every hour thereafter. This postponing behavior is in place since Zabbix 2.4.0.
Since Zabbix 3.0.0 it is possible to disable automatic housekeeping by setting HousekeepingFrequency to 0. In this case the housekeeping procedure can only be started by housekeeper_execute runtime control option and the period of outdated information deleted in one housekeeping cycle is 4 times the period since the last housekeeping cycle, but not less than 4 hours and not greater than 4 days.
Include no You may include individual files or all files in a directory in the configuration file.
To only include relevant files in the specified directory, the asterisk wildcard character is supported for pattern matching. For example: /absolute/path/to/config/files/*.conf. Pattern matching is supported since Zabbix 2.4.0.
See special notes about limitations.
JavaGateway no IP address (or hostname) of Zabbix Java gateway.
Only required if Java pollers are started.
This parameter is supported since Zabbix 2.0.0.
JavaGatewayPort no 1024-32767 10052 Port that Zabbix Java gateway listens on.
This parameter is supported since Zabbix 2.0.0.
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 since Zabbix 1.8.3.
ListenPort no 1024-32767 10051 Listen port for trapper.
LoadModule no Module to load at proxy startup. Modules are used to extend functionality of the proxy.
Format: LoadModule=<module.so>
The modules must be located in directory specified by LoadModulePath.
It is allowed to include multiple LoadModule parameters.
LoadModulePath no Full path to location of proxy modules.
Default depends on compilation options.
LogFile yes, if LogType is set to file, otherwise
no
Name of log file.
LogFileSize no 0-1024 1 Maximum size of log file in MB.
0 - disable automatic log rotation.
Note: If the log file size limit is reached and file rotation fails, for whatever reason, the existing log file is truncated and started anew.

0 - disabled
1 - enabled
This parameter is supported since Zabbix 3.4.0.
LogType no file Log output type:
file - write log to file specified by LogFile parameter,
system - write log to syslog,
console - write log to standard output.
This parameter is supported since Zabbix 3.0.0.
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 parameter is supported since Zabbix 1.8.2.
PidFile no /tmp/zabbix_proxy.pid Name of PID file.
ProxyLocalBuffer no 0-720 0 Proxy will keep data locally for N hours, even if the data have already been synced with the server.
This parameter may be used if local data will be used by third party applications.
ProxyMode no 0-1 0 Proxy operating mode.
0 - proxy in the active mode
1 - proxy in the passive mode
This parameter is supported since Zabbix 1.8.3.
Note that (sensitive) proxy configuration data may become available to parties having access to the Zabbix server trapper port when using an active proxy. This is possible because anyone may pretend to be an active proxy and request configuration data; authentication does not take place.
ProxyOfflineBuffer no 1-720 1 Proxy will keep data for N hours in case of no connectivity with Zabbix server.
Older data will be lost.
ServerPort no 1024-32767 10051 Port of Zabbix trapper on Zabbix server.
