Blank Cacti Graphs
- by tortib
I'm running Ubuntu 14.04 LTS and I'm having an issue with Cacti 0.8.8b not displaying any data in graphs. The graphs are being created and I see files in /var/lib/cacti/rra. My crontab entry for root is the following:
*/1 * * * * sudo -u www-data php -q /usr/share/cacti/site/poller.php > /dev/null
The output of ls -la /var/lib/cacti/rra is the following:
# ls -la /var/lib/cacti/rra/
total 1008

I tried to run the poller as root from the command line but it doesn't output anything useful nor does it graph any data. The device in cacti shows that that it's able to query snmp and ping is alive.
The graphs are still empty though. snmpwalk 127.0.0.1 -v2c -c public works as it should. It walks all MIBs. I'm quite perplexed as to why this isn't working any longer. It was graphing data but then it just stopped. And when it was graphing data it was graphing it intermittently.
Thank you for reading this problem and helping.
