How to keep zabbix_server.log's size under control?

[ifernandez]

Hello everyone,

I recently discovered that my zabbix_server.log occupied a whole 50GB. Since the zabbix server had been running normally for a couple of months, more or less, I decided to take down the logging level a notch, and reduced it from level 4 to 3. I deleted the existing zabbix_server.log and restarted the server.

My question is, is there any housekeeping option (housekeeping, or of any kind, for that matter) that can keep the logfile size controlled in a way? Even if it's by renaming the existing to zabbix_server.<DATE>.log or something, so I can have scripts that clean those out, or simply by deleting older entries in the logfile, or... something

I can't afford to have logs that take 50GB!

Thank you very much!

Default server/proxy/agent settings are

### Option: LogFileSize
#       Maximum size of log file in MB.
#       0 - disable automatic log rotation.
#
# Mandatory: no
# Range: 0-1024
# Default:
# LogFileSize=1

So seems like you've changed it to 0

I had indeed. It's always the obvious things, isn't it?

Thank you!

In my almost 20 years career as IT professional I've formed kind of two IT laws (lets name them as "kloczek's laws" ):
1st law: All bad IT cases is possible to put only in two baskets: simple and stupid
2nd law: Longer time you are working on fixing something than probability that it is something stupid is growing
