That's not a sensible format for a hostname.

Parentheses are not legal characters here.

Thanks Adam for your response, I'm checking on that.

Just wondering, if there is a script periodically running and doing this thing, should not it be the case of all devices? In my case, this is happening for all except one.

I should let you know, most recently, I have renamed all devices (except that one whose historical data is safe) in a format like this- "device_name(device_ip)". I had to work on /etc/hosts file for that. Could it be an issue?

Seeing no way out, I have deleted old rrd files today.

The only way this can really happen is if you have a script that is periodically running and doing something horrible.

 

Have you configured the housekeeping scripts to run with incorrect settings?

 

/settings/section=housekeeping/ will show the config entry for rrd file max age.

Everyday at a certain time, all historical graph data gets deleted. This is happening for all devices except one.

 

Can anyone tell what could be wrong?
