Performance issue after upgrading: Tips
Hello,
I recently upgrade from Zabbix 1.6.8 to 1.8.2 with some performance issue. All of them are fixed now. I just want to share these tips with you.
First issue:
My Zabbix server doesn't check all item for data. I was not depending on host, Zabbix agent version or type (actif or passif). The server queue was big, the agent doesn't recieve request for sending data.
Solution:
Set Zabbix server cache in zabbix_server.conf file to 128 MB (by defautl this setting was not in my 1.6.8 conf file)
Second issue:
The database performs a lot of IO on disk. So much that the SAN admin ask me to turn off the benchmarking apps.
Solution:
Add in Zabbix conf file one more settings for housekeeping:
With this settings, housekeeping will perform lots of IO only 15 minutes per hour (instead of 60 minutes per hour!).
