I can’t seem to find a way to log the status of an ethernet interface status. I’m trying to have a record of when this ethernet port goes up & down. (see screen shot below). I’m having issues with the device plugged into it.
And … in DUDE you can create datasets, that will collect (and compress over time) the collected data.
Datasets are made with SNMP OID and some functions in DUDE to round-subtract-average-convert the collected data.
I have no exemple for up-down collection (that is in the DUDE syslog as LOG records) , but follow traffic that way.
One thing to note: Dude works by polling… so it records an instantance reading of something. It does NOT do “traps” or events… so its may not capture if up/down perfectly, but close (and closer if you shorten the polling intervals).
This polling usually happens via probes on a device, which also create “data sources”. But you can “shortcut” the probe, by directly using the data sources as @bpwl shows
While you can also send logs from RouterOS device via Dude’s syslog server – which save the logs, but it does NOT let you query/alarm logs.
