Value Cache Recommendation Size

[faludi]

Hello,

We have 70 hosts in Zabbix and our value cache is setted to 50MB, but once a week it get higher than 95% and we have to restar Zabbix Server to flush Value Cache Size, there is a recommendation for value cache size by Host or Items or Triggers? Or every thing else? Or other setup to do in Server to bring it more stable?

You have few metrics about vcache:

• hits
• misses
• free, pfree
• used, pused
• total

Standard "Template App Zabbix Server" template provides enough hits, misses and pfree which are enough to say how much vcache needs to be setup.

Hello,

Thanks for your answer, attached here we have %free cache, cache hits and cache misses, but our main doubt is about % free value cache, because it get low % fast and we are not sure if it is normal or abnormal.
