1 Zabbix szerver

Áttekintés

Ez a szakasz a Zabbix szerverkonfigurációban támogatott paramétereket sorolja fel fájl (zabbix_server.conf).

Vegye figyelembe, hogy:

  • Az alapértelmezett értékek a démon alapértelmezett értékeit tükrözik, nem a szállított konfigurációs fájlok;
  • 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
AllowUnsupportedDBVersions no 0 Allow the server to work with unsupported database versions.
0 - do not allow
1 - allow

CacheUpdateFrequency no 1-3600 60 Determines how often Zabbix will perform update of configuration cache in seconds.
See also runtime control options.
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.
In case of 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.
DBName yes Database name.
In case of 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.
DBPassword no Database password.
Comment this line if no password is used.
DBPort no 1024-65535 Database port when not using local socket.
In case of 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.

This parameter is supported since Zabbix 4.0.0.
ExportType no List of comma-delimited entity types (events, history, trends) for real-time export (all types by default). Valid only if ExportDir is set.
Note that if ExportType is specified, but ExportDir is not, then this is a configuration error and the server will not start.
e.g.:
ExportType=history,trends - export history and trends only
ExportType=events - export events only
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.

The index cache size needs roughly 100 bytes to cache one item.
This parameter is supported since Zabbix 3.0.0.
HistoryStorageDateIndex no 0 Enable preprocessing of history values in history storage to store values in different indices based on date:
0 - disable
1 - enable
HistoryStorageURL no History storage HTTP[S] URL.
This parameter is used for Elasticsearch setup.
HistoryStorageTypes no uint,dbl,str,log,text Comma separated list of value types to be sent to the history storage.
This parameter is used for Elasticsearch setup.
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. For example: /absolute/path/to/config/files/*.conf.

JavaGatewayPort no 1024-32767 10052 Port that Zabbix Java gateway listens on.
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.
Formats:

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.

MaxHousekeeperDelete no 0-1000000 5000 No more than 'MaxHousekeeperDelete' rows (corresponding to [tablename], [field], [value]) will be deleted per one task in one housekeeping cycle.
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]

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.
