2 Zabbix proxy
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.
Parameters
| Parameter | Mandatory | Range | Default | Description |
|---|---|---|---|---|
| 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-64G | 8M | Size of configuration cache, in bytes. Shared memory size, for storing host and item data. The maximum value of this parameter was increased from 8GB to 64GB in Zabbix 5.0.1. |
| 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). |
| DataSenderFrequency | no | 1-3600 | 1 | Proxy will send collected data to the server every N seconds. Note that active proxy will still poll Zabbix server every second for remote command tasks. 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. |

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. This parameter is supported since Zabbix 5.0.0. |
||
| DBTLSCAFile | no (yes, if DBTLSConnect set to one of: verify_ca, verify_full) |
Full pathname of a file containing the top-level CA(s) certificates for database certificate verification. This parameter is supported since Zabbix 5.0.0. |

| DBTLSCertFile | no | Full pathname of file containing Zabbix server certificate for authenticating to database. This parameter is supported since Zabbix 5.0.0. |
||
| DBTLSKeyFile | no | Full pathname of file containing the private key for authenticating to database. This parameter is supported since Zabbix 5.0.0. |
||
| DBTLSCipher | no | The list of encryption ciphers that Zabbix server permits for TLS protocols up through TLSv1.2. Supported only for MySQL. This parameter is supported since Zabbix 5.0.0. |
||
| DBTLSCipher13 | no | The list of encryption ciphersuites that Zabbix server permits for TLSv1.3 protocol. Supported only for MySQL, starting from version 8.0.16. This parameter is supported since Zabbix 5.0.0. |

|
| 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. |

|
| 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. |

||
| JavaGatewayPort | no | 1024-32767 | 10052 | Port that Zabbix Java gateway listens on. This parameter is supported since Zabbix 2.0.0. |
| ListenBacklog | no | 0 - INT_MAX | SOMAXCONN | The maximum number of pending connections in the TCP queue. Default value is a hard-coded constant, which depends on the system. Maximum supported value depends on the system, too high values may be silently truncated to the 'implementation-specified maximum'. |
| 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. |

| 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. |
