Cacti stopped graphing

[hmalekib]

All of a sudden.. my cacti is no longer showing the traffic from my cisco switch...

I checked and the crontabs look good...
here are some graphs:

http://host84.iteraweb.com/cacti/graph_ ... 5&rra_id=3

http://host84.iteraweb.com/cacti/graph_ ... 5&rra_id=2

Whats the issue?

Any changes made to the cisco?
What does the logging (cacti and cisco) says?
Checked the community strings?

Nope no changes made.. under cacti it shows a connection under SNMP Information... Everything seems okay.

I remember when I had something similar.....
When changing an interface or the complete unit, the names of the interfaces where changed.... check the names with a refresh from cacti and verify them (even if you didn't change any hardware).

Yah well everything seems to be correct.. I dont know what the issue is..

Is it possible that its a PHP issue with the pooler?


This is what I have in the crontab and there is no issues:

*/5 * * * * /usr/local/bin/php /usr/local/apache/htdocs/cacti/poller.php > /dev/null 2>&1

Has the device been rebooted? If you do not have snmp ifindex-persist in the config, the ifindex numbers may have changed.

Also, is it just one device? or are all your graphs not updating?
Check the log size of cacti.log. If it is 2 Gb+ empty it by " > cacti.log" and then add <cacti dir>/log/cacti.log to your logrotate.conf

Nothing in the logs, I just removed the device (Cisco switch) and added it again.. it was fine however when I look at the device.. the status is as follows:

Unknown <host> 0 0 100%

And its not generating any graphs when I re added the device.

wait a bit and see. It should kick back the system info immediately under device properties.

What version snmp is on the device and what version are you polling with?

[hmalekib]

They are both version 1
