First, I must apologize for yet another question about "graphs not working". However, I have read everything I can find in the mail archives, in forums, and have reinstalled multiple times following the instructions exactly. Each time with the -nan listed for all data points. Verified permissions on the rrd and tmp folders and both match the same user/group as what everything is running as. I eventually resorted to installing and running everything as root to try and resolve permission errors. Once I figure out what's wrong I'll go back to std user. Sorry for the long email, but I wanted to include everything I know so far.
Monitoring Host:
Ubuntu 13.04
Observium 13.12.4811
Virtual Machine on Hyper-V
Currently Monitored Devices:
3 HP Procurve Switches
1 Ricoh Copier
2 Sonicwall Firewalls
Testing results thus far:
1. Real-time graphing works for each device.
2. Every other graph is drawn, but has "-nan" for each data point. Same for each device.
3. Prior to installing jpgraph (to get billing to work) all devices did not list traffic data under the Ports tab.
4. Post jpgraph install and config, traffic info under Ports tab works for Ricoh Copier and 1 of 3 HP Procurve switches, but no other devices. Only 0 bps is listed.
5. Enabled rrdcached in the config file with adding $config['rrdcached'] = "unix:/var/run/rrdcached.sock";.
6. Ran discovery and polling for everything again and all devices list stats for traffic under Ports tab.
7. Billing still doesn't capture traffic data on any device.
8. Billing Accurate Graphs gives an error of 25121 - "Empty input data array specified for plot. Must have at least one data point."
I believe billing errors may be related to the rest.
I ran discovery and polling in debug mode writing to text files and it appears that the data is being pulled from the device correctly. It also looks like it writes the data into the rrd device file and updates the mysql database without showing any errors. Thus, I'm perplexed as to what it could be and have no direction to look into... Help would be appreciated.
Thanks,
Jason
