When I query the discovery_server from the snmpcollector probe the operation succeeds:

"Profiles from discovery_server are being imported"

<Please see attached file for image>

<Please see attached file for image>

However, no device is actually imported. 

The snpcollector.log contains this errror:

May 08 16:12:32:314 [Thread-7, snmpcollector] Could not import devices from discovery server because of error: UNHANDLED_EXCEPTION caused by: Unhandled exception thrown in callback: nisMetadata must not be null or empty
May 08 16:12:32:314 [Thread-7, snmpcollector] (1) error, Received status (1) on response (for sendRcv) for cmd = 'get_devices'


 

This error can be related to an issue occurring in the discovery_server and the udm_manager probe. 

UIM 8.5.1
snmpcollector 3.44

 

We have seen the following actions resolving this issue:

1. Deactivate the discovery_server 
2. Deactivate the udm_manager probe 
3. deactivate snmpcollector 

4. Execute against your UIM database the following query*:

DROP TABLE DATOMIC_KVS 

5. Start discovery_server
6. Start udm_manager
7. start snmpcollector



*The query deletes cached data. no current data is lost by executing this query. 

 

If the procedure doesn't fix the issue please engage UIM support and provide the following information:

8. Set log level to 5 in the snmpcollector probe and logsize to 10000 
9. Set log level to 5 in the discovery_server and logsize to 10000 
10. Set log level to 5 in the udm_manager probe and logsize to 10000
