"No Data Found" SNMP

rtarson · ‎04-01-2022

Hello,

So I am trying to add Custom OID templates to Lansweeper instance we have here. I have used Synology Documentation and its very own MIB file and imported it into Lansweeper. I matched the OIDs to the device and it should be reading completely fine. Not to mention it is able to scan the base OID fine.

As seen in the screen shot the OID are scanned but "No Data Found".

I followed the trouble shooting tips that can be found here

I was able to open devicetester and ran a test. However if you notice under custom scanning OIDs it only shows the main OID scan object.

Does anyone have any ideas why this is happening?

Has this issue been fixed, if so I would like to know how this was fixed.

ObjectID = 1.3.6.1.4.1.8072.3.2.10 is a reserved OID. This is a generic ID for linux. Reading though all the information for the last few hours on lansweeper I am seeing the following information. Device Scanner insert your custom OID to scan and see if it will scan them. Sadly if the device responds to 1.3.6.1.4.1.8072.3.2.10 then no matter what you put in your custom scan area are ignored. Synology you can download and install the OID's into Lansweeper. No problem. Added them to assets too. IF you run from an Ubuntu box the command "snmpwalk -v3 -l AuthNoPriv -a MD5 -u MyUserName -A MyPassword 10.20.30.40 1.3.6.1.4.1.6574.1" this will give you the information about your synology system etc.. change the ending 1 to a 2 like this 1.3.6.1.4.1.6574.2 and you will get with the snmpwalk your disk information. All this is ignored with Lansweepers scan tool. A suggestion was made in another post to download paessler snmp tester (PRTG), and again just like with the ubuntu box and snmpwalk I am able to get full outputs using the OID supplied by Synology.

Please fix your Device Tester & and Please fix Lansweeper so it will scan asset which have been assigned to a pool which OID's are imported to. It will show me that it scanned the 17 OID's I requested but no data. This is as far as I have gotten after many hours of troubleshooting. Again other scanning tools have no problems making the request but Lansweeper fails in this case.

Hi @JesperH

1.3.6.1.4.1.8072.3.2.10 is a reserved OID for Linux systems, and you should get results for custom OIDs when scanning Linux devices. Could you share some screenshots of the results you get with the Lansweeper scan tool?

Here is a list of items I talked about

Screenshot of the Paessler output

The output from an ubuntu box using snmpwalk.

Lansweepers Device Tester and the logfile.

-- Items that have been modified.

All IP's have been scrubbed, usernames and passwords covered or scrubbed and any other personally identifiable information

As said.. what ever you put into the Custom OID box you will not get that scanned if it sees the Linux Default OID in the original scan saying that it responds to a linux scan.

The devicetester_logfile should include the number of disks and disk information and as you can see from the logs its never scanned even though its in the custom OID

Let me know if you want more information I will be happy to share.
