Graph not being displayed

[jjteo]

Hi , my graphs are not being displayed after i created them. May i know what am i doing wrong?
This is the debug output.
It seems that the rrdtool is unable to find the .rrd file. How would i go about solving this error?

I am currently trying to monitor the cpu usage of the pc that i am using
This is the current config

EDIT: The graphs are being displayed but there is no data being updated. After i export the graph as a .csv file , under the columns Free and Swap , the data is NaN.


Thanks

Does anyone have the same problem?

I have a similar problem however my graphs are coming up with an error -1.#J

I know that you can do the debug mode to see what's running as the data source, but is there a way to monitor a specific graph's poller output?

I'm curious to see if the poll is getting any data back. I know that other SNMP queries to the device work fine.

Though it's not for specific graphs but for specific hosts, you can perform polling tests for particular target.

Hi,

Managed to fix nearly all of the issues today by doing the following:
- Stopping the poller and waiting 10 minutes (we're on a 5 minute schedule)
- Clearing out the poller cache and confirming its empty
- Restarting SNMP on the routers that were affected
- Waiting 10 minutes and observing that the graphs were now being displayed okay

Suggest that this troubleshooting be added to the normal "my graphs are empty / getting no results"
