Error drawing graph in Centos and RPi


I’m added a few Centos 7 VMs and RPIs to my LibreNMS and although some of the data has come through some graphs appear red with the remark ‘Error drawing graph’, they have been running for hours in Librenms

Any ideas why this is happening?

I will continue to do some research.


And your centos7 vm’s and rpi’s having good snmp inplemented for letting your librenms poll?

And u can get an snmp walk from libre to one off your devices?

U should add a switch or router 1st if u like to test graphs,

And what does show rrd command do if u try that?

I’ve add some OIDs to CentOS (vi /etc/snmp/snmpd.conf)

I didn’t know I needed to do this, is there a list of what I need to add to Centos/Pi’s to fully open them up for monitoring?

If I run snmpwalk -v2c -c m0n1t0r 192.168.0.x on these devices I got lots of info, too much to paste here.

This is what I see on a Pi

On Centos
