I have four RouterOS devices:
CCR2116-12G-4S+, CRS326-24S+2Q+, and two CRS310-8G+2S+
All devices are running RouterOS 7.18
I have SNMP v3 working and enabled on all four devices.
I have SNMP limited to only LibreNMS box.
I have given my SNMPv3 user read/write privileges
I have installed the agent script for LibreNMS via this link:
https://docs.librenms.org/Support/Devic … /Routeros/
This works for the CCR2116-12G-4S+ and both CRS310-8G+2S+…
However I cannot get it to work with my CRS326-24S+2Q+
I have compared the SNMP settings, user, script ownership, the script itself. All are the same.
When I look at the run count for the script, the run count is going up much faster than the other boxes.
When I install the script, the script, the job and “txtContent” environment gets created.
If I run the script manually, the “vlansu” and “vlanst” environments get created.
If I let LibreNMS run the script, the “vlansu” and “vlanst” environments do NOT get created.
Seems like a permissions issue, but I can’t seem to figure it out yet.
I have disabled write, saved, enabled write,save on the SNMPv3 user to see if that helps.
I know the SNMPv3 user works because everything else for the CRS326-24S+2Q+ populates in LibreNMS correctly.
Observations (Edited to add info):
The script user owner is a “full” group member. (I removed “admin”) and both the user and the group is exactly the same across all four devices.
I removed the script, job, and all three created environments and re-added the script. Then ran rediscovery in LibreNMS.
I re-applied the SNMPv3 secrets again. No change.
