Also a snippy from the rrd directory of the router.

Hi Peter,

Try this URL (assuming you have a port with the id of 1, since it's a new install : 

/graphs/type=port_bits/to=1504899166/id=1/from=1504812766/height=300/width=1152/showcommand=yes/

If the graph is broken on that page, you should still see the error output towards the bottom of the page.

You can see if the poller is correctly generating RRDs by looking in the observium/rrds/<hostname>/ directories

Tom,

With running smooth i mean it polls normally. Al info on the site is accurate.

Running 36 threads now. Was pretty slow before.

Added rrdcached also.

Any way to check if the permissions are set ok?

This is what i have setup in my cron jobs.

That is not required, what's more, it's recommended against as it can cause issues.

Peter, if you don't have graphs, what do you consider 'running smooth' ? It's likely an issue with the cron jobs, and/or permissions on the RRD files.

Hello,

Currently Eurofiber is testing Observium in our live network.

So far it runs smooth.

We only have 1 problem. The graphs are empty (-nan).

My guess its a config.php error but im not sure.

I have added a screenshot and the config.php file.

Regards,

Met vriendelijke groet,
