Trying to get SNMP applications working

Help

Hi,

I’m trying to get applications through SNMP extend working. I’ve added the extend lines in my snmpd.conf, and snmpwalk shows it’s working, I think:

# snmpwalk -v2c -c public localhost NET-SNMP-EXTEND-MIB::nsExtendOutput2Table

I’ve enabled the apache and mysql applications in LibreNMS for that device but the graphs aren’t filling up.

The (relevant) output from ./poller.php -h localhost -r -d -m applications is:

What’s going wrong here?

I’m also trying to configure the ups-apcups application. The docs say I should enable the module in the LibreNMS webinterface but I can’t find it there; it’s simply not in the list.

I’m in the same boat - haven’t gotten any further than you have, but if I resolve it I’ll post back.
My setup
LibreNMS server - ubuntu 14.04
Apache2 servers - ubuntu 14.04, 16.04
Application is installed, RRD directory shows data files that grow, but graphs never show up.

So, does anybody have suggestions?

I can get it working on ubuntu 16.04 apache servers, but not on 14.04 - seems to be since 14.04 uses Upstart - I haven’t yet figured out how to auto start the libre agent with Upstart.
