Hello,
I’ve several mikrotik-based devices (~100) on the field and I configured my monitoring environment to catch both Routerboard Temperature and Voltage.
Reply from those OID is not reliable, i.e. after some time the device reports “There is no such variable name in this MIB”. After a reboot, OID works again but only for some time, then stops again. Also, sometimes, OID resume by itself without rebooting.
I was not able to catch anything on RB logs.
Am I missing something or RouterBoard’s “environment monitoring” via SNMP is not so reliable?
Thanks
I also suspect snmp from not being effectively implemented in ros. Snmp queries are quite resource exhausting, causing various problems to the responding devices.
This is characteristic of the net-snmp package. It has been a resource hog from 1995, and probably will ever be.
I also often wonder why it is so slow, but never took the step of actually looking in the code.
