Hi everyone,

I have a problem with snmp on one of my servers, which is very strange. OS: windows server 2012 R2

I Have installed the snmp feature, and configured access on the service. When trying to get uptime, using the Peassler SNMP tester tool, i get the following error: (I'm running the test from the probe server on the same vlan)

Paessler SNMP Tester - 20.2.4 Computername: SERVER01 Interface: xx.xx.xx.xx
18-02-2021 14:55:28 (2 ms) : Device: xx.xx.xx.xxx
18-02-2021 14:55:28 (4 ms) : SNMP v2c
18-02-2021 14:55:28 (5 ms) : Uptime
18-02-2021 14:55:28 (8 ms) : SNMP Datatype: ASN_TIMETICKS
18-02-2021 14:55:28 (10 ms) : -------
18-02-2021 14:55:28 (12 ms) : DISMAN-EVENT-MIB::sysUpTimeInstance = 34313 ( 5 minutes 43 seconds )
18-02-2021 14:55:28 (15 ms) : SNMP Datatype: SNMP_EXCEPTION_NOSUCHOBJECT
18-02-2021 14:55:28 (17 ms) : HOST-RESOURCES-MIB::hrSystemUptime.0 = #N SNMP_EXCEPTION_NOSUCHOBJECT222 ( 0 seconds )
18-02-2021 14:55:28 (19 ms) : Done

If I try to add an SNMP sensor for the server on PRTG, I get the follow error:

The sensor could not find any matching data on the monitored device. To resolve this issue, check if SNMP is enabled on the device. Also check if the Dell OpenManage Server Administrator is correctly installed on the target server. Or check if the needed OIDs can be reached. For more information, see https://kb.paessler.com/en/topic/68040. (code: PE187)

What is going on here, is there some strange settings on the server, that is preventing the SNMP reply? (No local firewalls are enabled)

Hope you can help.

Hi Toma,

Thank you very much for your contact.

The error message implies that the required OIDs for this sensor are not available. Enabling SNMP on recent Windows versions can be tricky as there are plans to deprecate it for years already. While it is still possible, it became more difficult and hidden over time. Please check this how-to in case you missed something:
How to enable SNMP on your operating system (Paessler Blog)

We are using the OID 1.3.6.1.2.1.1.3.0 for the SNMP System Uptime sensor. Please also check if a Custom OID query from the SNMP Tester shows different values.

Best,
Sebastian

Hi Sebastian,

Thank you for your reply. Naturally I checked guides and searched the internet for solutions before I posted here, so I was out of obvious options.

Everything was set up correctly, so I also started to look in a different direction, and it shows up that another service was using the same port. After changing that it now works fine.
