I’m making another run at this librenms thing.
Running this; CentOS Linux release 7.1.1503 (Core)
Using this; https://docs.librenms.org/#Installation/Installation-CentOS-7-Apache/
Fresh install, ran daily.sh right off the bat.
[root@librenms librenms]# ./validate.php
====================================
Component | Version
--------- | -------
LibreNMS | 1.33-31-gaef1a5f
DB Schema | 215
PHP | 7.1.10
MySQL | 5.5.56-MariaDB
RRDTool | 1.4.8
SNMP | NET-SNMP 5.7.2
====================================
[OK] Database connection successful
[OK] Database schema correct
[FAIL] Discovery has never run. Check the cron job
I’m still only able to add devices through the GUI by forcing it. Deviced added through the shell were the same in my previous install attempt.
Servers are green lighted when they’re added, but get a big red SNMP box after a little while. Charts all get “Error Drawing Graph”.
Selinux is disabled;
[root@librenms librenms]# sestatus
SELinux status: disabled
[root@librenms librenms]#
I can ping, ssh and snmpwalk the target hosts from this server with success.
I ran poller-wrapper.py because I read it somewhere and it made sense at the time to do it. I freely admit that doing this was a flail move.
[root@librenms librenms]# /opt/librenms/poller-wrapper.py
INFO: starting the poller at 2017-11-03 14:44:28 with 16 threads, slowest device s first
INFO: worker Thread-1 finished device 1 in 12 seconds
INFO: worker Thread-2 finished device 2 in 12 seconds
INFO: poller-wrapper polled 2 devices in 12 seconds with 16 workers
I’d kind of like to kick Munin out of the building and switch to this using SNMP and Nagios for other stuff.
Can someone help with the SNMP & graphs part?
