- A Zabbix csak UTF-8 kódolásban támogatja a konfigurációs fájlokat anélkül BOM;
- A "#" karakterrel kezdődő megjegyzések csak a kezdetekkor támogatottak a vonal.
Parameters
| 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 |

|
| HousekeepingFrequency | no | 0-24 | 1 | Determines 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 Housekeeping is removing outdated information from the database.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(for example, when history and trend periods are greatly reduced), no more than 4 times HousekeepingFrequency hours of outdated information are deleted in one housekeeping cycle, for each item. Thus, if HousekeepingFrequency is 1, no more than 4 hours of outdated information (starting from the oldest entry) will be deleted per cycle.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. 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case the housekeeping procedure can only be started by housekeeper_execute runtime control option and the period of outdated information deleted in one housekeeping cycle is 4 times the period since the last housekeeping cycle, but not less than 4 hours and not greater than 4 days. See also runtime control options. |
| 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.

| 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. |
|
| ListenPort | no | 1024-32767 | 10051 | Listen port for trapper. |
| LoadModule | no | Module to load at server startup. Modules are used to extend functionality of the server.

If set to 0 then no limit is used at all. In this case you must know what you are doing, so as not to overload the database! 2 This parameter applies only to deleting history and trends of already deleted items. |
| NodeAddress | no | IP or hostname with optional port to override how the frontend should connect to the server. Format: <address>[:port] The priority of addresses used by the frontend to specify the server address is: NodeAddress (1); ListenIP (if not 0.0.0.0 or ::) (2); localhost (default) (3) See also: HANodeName parameter |

Lábjegyzetek
1 Vegye figyelembe, hogy túl sok adatgyűjtési folyamat (pollerek, elérhetetlen lekérdezők, ODBC lekérdezők, HTTP lekérdezők, Java lekérdezők, pingelők, trapperek, proxypollers) IPMI-kezelővel, SNMP trapperrel és előfeldolgozással együtt a dolgozók kimeríthetik a folyamatonkénti fájlleíró korlátot a előfeldolgozási menedzser.
Ez a Zabbix szerver leállását okozza (általában röviddel a kezdés után, de néha több időt is igénybe vehet). Az A konfigurációs fájlt felül kell vizsgálni, vagy a korlátot meg kell emelni kerülje el ezt a helyzetet.
2 Ha sok elemet töröl, az növeli a terhelést a adatbázis, mert a házvezetőnőnek el kell távolítania az összes előzményt adatok, amelyekkel ezek a tételek rendelkeztek. Például, ha csak 1 elemet kell eltávolítanunk prototípus, de ez a prototípus 50 gazdagéphez és minden gazdagéphez kapcsolódik a prototípust 100 valódi tárgyra bővítik, összesen 5000 darabot kell el kell távolítani (1*50*100). Ha a MaxHousekeeperDelete értéknél 500 van beállítva (MaxHousekeeperDelete=500), a házvezetőnő folyamatnak el kell távolítania legfeljebb 2500000 érték (5000*500) az előzményekből törölt elemekhez és trendtáblázatok egy ciklusban.
