Hi

First time user, just getting setup with 10 devices to monitor

I have 3 DLINK switches im trying to monitor, and when first discovered, all the info about the device gets pulled:

|2018-02-24 21:45:05||sysObjectID -> .1.3.6.1.4.1.171.10.76.27|
|2018-02-24 21:45:05||sysName -> poe_switch|
|2018-02-24 21:45:05||sysDescr -> DGS-1210-24P 4.21.B008|
|2018-02-24 21:45:05||Location -> Loft|

and then 10 mins later, something happens, and all the data is missing

2018-02-24 21:55:11 sysObjectID ->
2018-02-24 21:55:11 sysName ->
2018-02-24 21:55:11 sysDescr ->
2018-02-24 21:55:11 Hardware -> Rev.
2018-02-24 21:51:02 Could not issue recovery for rule ‘Devices up/down’ to transport ‘mail’ Error: You must provide at least one recipient email address.
2018-02-24 21:51:02 Could not issue critical alert for rule ‘Port status up/down’ to transport ‘mail’ Error: You must provide at least one recipient email address.

Any idea why the device would discover properly, and then this would happen?

I am still getting all the stats from the device, and my graphs are populating with data, i can see interface graphs etc etc, its just this info that goes missing!

If its a known problem, thats cool, assume it will get sorted at some point?

Have you tried updating the dlink firmware?

I dont think its a “known” issue i think its buggy SNMP implention by Dlink.
