2 Proxy Zabbix
Overview
This section lists parameters supported in a Zabbix proxy configuration file (zabbix_proxy.conf). Note that:
- The default values reflect daemon defaults, not the values in the shipped configuration files;
- Zabbix supports configuration files only in UTF-8 encoding without BOM;
- Comments starting with "#" are only supported in the beginning of the line.
Dettagli dei parametri
AllowRoot
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.
Default: 0 | Values: 0 - do not allow; 1 - allow
AllowUnsupportedDBVersions
Allow the proxy to work with unsupported database versions.
Default: 0 | Values: 0 - do not allow; 1 - allow
CacheSize
The size of the configuration cache, in bytes. The shared memory size for storing host and item data.
Default: 32M | Range: 128K-64G
ConfigFrequency
This parameter is deprecated (use ProxyConfigFrequency instead).
How often the proxy retrieves configuration data from Zabbix server in seconds.
Active proxy parameter. Ignored for passive proxies (see ProxyMode parameter).
Default: 3600 | Range: 1-604800
DataSenderFrequency
The proxy will send collected data to the server every N seconds. Note that an active proxy will still poll Zabbix server every second for remote command tasks.
Active proxy parameter. Ignored for passive proxies (see ProxyMode parameter).
Default: 1 | Range: 1-3600
DBHost
The database host name.
With MySQL localhost or empty string results in using a socket. With PostgreSQL only empty string results in attempt to use socket. With Oracle empty string results in using the Net Service Name connection method; in this case consider using the TNS_ADMIN environment variable to specify the directory of the tnsnames.ora file.
Default: localhost
DBName
The database name or path to the database file for SQLite3 (the 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 the Zabbix server is using.
With Oracle, if the Net Service Name connection method is used, specify the service name from tnsnames.ora or set to empty string; set the TWO_TASK environment variable if DBName is set to empty string.
Mandatory: Yes
DBPassword
La password del database. Commenta questa riga se non viene utilizzata alcuna password. Ignorato per SQLite.
DBPort
The database port when not using local socket. Ignored for SQLite.
With Oracle, if the Net Service Name connection method is used, this parameter will be ignored; the port number from the tnsnames.ora file will be used instead.
Range: 1024-65535
DBSchema
Il nome dello schema del database. Utilizzato per PostgreSQL.
DBSocket
Il percorso del file socket MySQL.
La porta del database quando non si utilizza il socket locale. Ignorato per SQLite.
Impostazione predefinita: "3306".
DBUser
L'utente del database. Ignorato per SQLite.
DBTLSConnect
Setting this option enforces to use TLS connection to the database:
required - connect using TLS
verify_ca - connect using TLS and verify certificate
verify_full - connect using TLS, verify certificate and verify that database identity specified by DBHost matches its certificate
On MySQL starting from 5.7.11 and PostgreSQL the following values are supported: "required", "verify", "verify_full".
On MariaDB starting from version 10.2.6 "required" and "verify_full" values are supported.
By default not set to any option and the behavior depends on database configuration.
DBTLSCAFile
The full pathname of a file containing the top-level CA(s) certificates for database certificate verification.
Mandatory: no (yes, if DBTLSConnect set to verify_ca or verify_full)
DBTLSCertFile
Il percorso completo di un file contenente il certificato proxy Zabbix per l'autenticazione al database.
DBTLSKeyFile
The full pathname of a file containing the private key for authenticating to the database.

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).
Default: 3 | Range: 0-5
EnableRemoteCommands
Whether remote commands from Zabbix server are allowed.
0 - not allowed
1 - allowed
Default: 0
ExternalScripts
The location of external scripts (depends on the datadir compile-time installation variable).
Default: /usr/local/share/zabbix/externalscripts
Fping6Location
The location of fping6. Make sure that the fping6 binary has root ownership and the SUID flag set. Make empty ("Fping6Location=") if your fping utility is capable to process IPv6 addresses.
Default: /usr/sbin/fping6
FpingLocation
The location of fping. Make sure that the fping binary has root ownership and the SUID flag set.
Default: /usr/sbin/fping
HistoryCacheSize
The size of the history cache, in bytes. The shared memory size for storing history data.
Default: 16M | Range: 128K-2G
HistoryIndexCacheSize
The size of the history index cache, in bytes. The shared memory size for indexing the history data stored in history cache. The index cache size needs roughly 100 bytes to cache one item.
Default: 4M | Range: 128K-2G
Hostname

Allowed characters: alphanumeric, '.', ' ', '_' and '-'.
Maximum length: 128
Default: Set by HostnameItem
HostnameItem
The item used for setting Hostname if it is undefined (this will be run on the proxy similarly as on an agent). Ignored if Hostname is set.m
Does not support UserParameters, performance counters or aliases, but does support system.run[].
Default: system.hostname
HousekeepingFrequency
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.
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.
Default: 1 | Range: 0-24
Include
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.

ProxyMode
The proxy operating mode.
0 - proxy in the active mode
