Howdy,
Thanks for taking the time to look into this. If anyone can help me out then that’d be appreciated.
For simplicity reasons, I’ll label the two servers as the following:
Server A - Server with LibreNMS installed (Ubuntu 18.04)
Server B - Server being monitored through SNMP (Ubuntu 18.04)
I followed the steps outlined in https://docs.librenms.org/#Extensions/Applications/#smart to start monitoring the SMART values of my hard drives.
On Server B’s snmpd.conf
I added extend smart /etc/snmp/smart
to the configuration file. When running ./smart
, I get the following output:
sda,0,0,null,null,null,null,null,null,null,31,0,0,0,0,null,null,0,0,0,0,0,0,0,0
sdb,0,0,null,null,null,null,null,null,null,34,0,0,0,0,null,null,1,0,0,0,0,1,0,0
sdc,0,0,null,null,null,null,null,null,null,31,0,0,0,0,null,null,1,0,0,0,0,1,0,0
sdd,0,0,null,null,null,null,null,null,null,36,0,0,0,0,null,null,0,0,0,0,0,0,0,0
On Server A, I keep getting graphs like this, even after 24 hours of monitoring:
I want to say my assumption is that the output of the SMART script contains nulls which is tripping up the graphs, but I’m not too sure to be honest. I haven’t looked too in-depth in the SMART script but that’s my next step.
My questions:
- What’s the best way to get around this and get LibreNMS to start monitoring my SMART data?
- Why is the graph being plotted with nan not only for the selected graphs/values there, but for all SMART app based plots?
Thank you.
