Zabbix proxy plugin: private shared memory - Cannot allocate memory

[rainerle]

Hi,

trying to migrate a dedicated Zabbix proxy to OPNsense. Startup fails with

Code Select Expand


cannot initialize database cache: cannot get private shared memory of size 536870912 for history index cache: [12] Cannot allocate memory

Zabbix Proxy Settings:

Code Select Expand


root@opnsense01:~ # cat /usr/local/etc/zabbix4/zabbix_proxy.conf
...
CacheSize=8M
HistoryCacheSize=64M
HistoryIndexCacheSize=512M
...


Above Proxy values are from the existing proxy...

What do I have to set specifically with sysctl ( /system_advanced_sysctl.php ) to get that proxy up?

Best regards
Rainer

How many new values per second do you have? 500 MB is quite huge for a proxy

Good morning Michael,

no idea how this is related to my question  ;)

Code Select Expand


Number of hosts (enabled/disabled/templates) 828
Number of items (enabled/disabled/not supported) 206957
Number of triggers (enabled/disabled [problem/ok]) 34127
Number of users (online) 33
Required server performance, new values per second 1174.31


My next post will be how to set "ProxyOfflineBuffer" from 1 to 72 and if you could add "Include /usr/local/etc/zabbix4/zabbix_proxy.d/" to the generated zabbix_proxy.conf.

Best regards
Rainer

P.S.: Oh, and RAM is cheap these days:

It was just unclear to me that you want to hold values over the weekend if there's a crash somewhere. Now it's clear :)
