I’ve only just noticed this, but the ‘Latency’ option that appears in each device we monitor is missing:

When I look on our other instance of LibreNMS we see it there:

How do I get it to show?


It’s only shown if you have any data in your device_perf table for that device.

If you don’t have data in there then you have either disabled icmp_check (lnms config:get icmp_check) or you have this turned on for the device

When I run that command it says true which I think means it’s enabled?

How do I check the device_perf for a device?

select * from device_perf where device_id=X;

Replace X with your device id.

This is what I get for all devices I’ve tried:

Database changed

MariaDB [librenms]> select * from device_perf where device_id=491;

Empty set (0.001 sec)

MariaDB [librenms]>

Have you checked you haven’t turned off ICMP as per my screenshot?
