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 Housekeeping is removing outdated information from the database.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(for example, when history and trend periods are greatly reduced), no more than 4 times HousekeepingFrequency hours of outdated information are deleted in one housekeeping cycle, for each item. Thus, if HousekeepingFrequency is 1, no more than 4 hours of outdated information (starting from the oldest entry) will be deleted per cycle.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case the housekeeping procedure can only be started by housekeeper_execute runtime control option and the period of outdated information deleted in one housekeeping cycle is 4 times the period since the last housekeeping cycle, but not less than 4 hours and not greater than 4 days.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

If the certificate file contains also the private key, leave the SSL key file field empty.
The directory containing this file is specified by the configuration parameter SSLCertLocation.
This option can be omitted but is recommended for CyberArkCCP vault.
The name of the SSL private key file used for client authentication.
The private key file must be in PEM1 format.
The directory containing this file is specified by the configuration parameter SSLKeyLocation.
This option can be omitted but is recommended for CyberArkCCP vault.
The HashiCorp Vault authentication token that should have been generated exclusively for Zabbix server with read-only permission to the paths specified in Vault macros and read-only permission to the path specified in the optional VaultDBPath configuration parameter.
It is an error if VaultToken and VAULT_TOKEN environment variable are defined at the same time.
Mandatory: Yes, if Vault is set to HashiCorp; otherwise no
The vault server HTTP[S] URL. The system-wide CA certificates directory will be used if SSLCALocation is not specified.
Default: https://127.0.0.1:8200
The shared memory size for storing VMware data.
A VMware internal check zabbix[vmware,buffer,...] can be used to monitor the VMware cache usage (see Internal checks).
Note that shared memory is not allocated if there are no vmware collector instances configured to start.
Default: 8M
Range: 256K-2G
The delay in seconds between data gathering from a single VMware service.
This delay should be set to the least update interval of any VMware monitoring item.
Default: 60
Range: 10-86400
The delay in seconds between performance counter statistics retrieval from a single VMware service. This delay should be set to the least update interval of any VMware monitoring item that uses VMware performance counters.
Default: 60
Range: 10-86400
The maximum number of seconds a vmware collector will wait for a response from VMware service (vCenter or ESX hypervisor).
Default: 10
Range: 1-300
The HTTP[S] URL to Zabbix web service in the format <host:port>/report
.
Example:
WebDriver interface HTTP[S] URL.
Example (used with Selenium WebDriver standalone server):
1 Note that too many data gathering processes (pollers, unreachable pollers, ODBC pollers, HTTP pollers, Java pollers, pingers, trappers, proxypollers) together with IPMI manager, SNMP trapper, preprocessing workers, and discovery workers can exhaust the per-process file descriptor limit for the preprocessing manager.
Exhausting the file descriptor limit will cause Zabbix server to stop, typically shortly after startup but sometimes taking longer. To avoid such issues, review the Zabbix server configuration file to optimize the number of concurrent checks and processes. Additionally, if necessary, ensure that the file descriptor limit is set sufficiently high by checking and adjusting system limits.
2 When a lot of items are deleted it increases the load to the database, because the housekeeper will need to remove all the history data that these items had. For example, if we only have to remove 1 item prototype, but this prototype is linked to 50 hosts and for every host the prototype is expanded to 100 real items, 5000 items in total have to be removed (1*50*100). If 500 is set for MaxHousekeeperDelete (MaxHousekeeperDelete=500), the housekeeper process will have to remove up to 2500000 values (5000*500) for the deleted items from history and trends tables in one cycle.
