1 Zabbix server
The parameters supported in a Zabbix server configuration file:
| Parameter | Mandatory | Range | Default | Description |
|---|---|---|---|---|
| AlertScriptsPath | no | /usr/local/share/zabbix/alertscripts | Location of custom alert scripts (depends on compile-time installation variable datadir). | |
| AllowRoot | no | 0 | Allow the server to run as 'root'. If disabled and the server is started by 'root', the server 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, item and trigger data. Upper limit used to be 2GB before Zabbix 2.2.3. |
| CacheUpdateFrequency | no | 1-3600 | 60 | How often Zabbix will perform update of configuration cache, in seconds. |
| 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. 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. |
||
| DBPort | no | 1024-65535 | 3306 | Database port when not using local socket. Ignored for SQLite. |
| DBSchema | no | Schema name. Used for IBM DB2 and PostgreSQL. | ||
| DBSocket | no | /tmp/mysql.sock | Path to MySQL socket. | |
| DBUser | no | Database user. Ignored for SQLite. | ||
| 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 debuging for web and VMware monitoring (can be set only using runtime control options) |
| 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! |
|
| HistoryCacheSize | no | 128K-2G | 8M | Size of history cache, in bytes. Shared memory size for storing history data. |
| HistoryTextCacheSize | no | 128K-2G | 16M | Size of text history cache, in bytes. Shared memory size for storing character, text or log history data. |
| HousekeepingFrequency | no | 1-24 | 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 history and trend periods are greatly reduced), no more than 4 times HousekeepingFrequency hours of outdated information are deleted in one housekeeping cycle, for each item. 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 server startup housekeeping is postponed for 30 minutes after server start. Thus, if HousekeepingFrequency is 1, the very first housekeeping procedure after server start will run after 30 minutes, and will repeat with one hour delay thereafter. This postponing behavior is in place since Zabbix 2.4.0. |
| 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. |

| 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. |

| 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. |
| MaxHousekeeperDelete | no | 0-1000000 | 500 | No more than 'MaxHousekeeperDelete' rows (corresponding to [tablename], [field], [value]) will be deleted per one task in one housekeeping cycle. SQLite3 does not use this parameter, deletes all corresponding rows without a limit. If set to 0 then no limit is used at all. In this case you must know what you are doing!
