Display CPU/MEM with LibreNMS

Support

Hi All,

Anyone have any luck displaying CPU/MEM usage on LibreNMS with the Weathermap plugin? It worked great on Cacti.

Also looking for this! Have tried the cacti method and it doesn’t seem to work - maybe it doesn’t like the variable?

CPU/Mem of what? A linux server? A router?

I have a very small librenms install, but it looks to me like

TARGET /opt/librenms/rrd/172.21.21.8/ucd_cpu.rrd:user:system

would do the trick for CPU on my linux server on 172.21.21.8

Basically though, point weathermap at the right rrd file, and it will complain that the DS names are wrong, but it will also tell you what the valid DS names are. Or you can use rrdtool info xxxxx.rrd to get the same information (near the top of the output).
