DNA Center not sending events to syslog

[andreasd1]

Our DNA Center recently stopped sending events to syslog

DNAC version: 2.3.5.6

Are there any troubleshooting steps we should perform? "Try-It Now" from the Event Catalog is working (syslog server receives the event), but the subscriptions have stopped working.

call the TAC...
BTW. can u still see syslog servers configured under Setting/External Services/Syslog?

Is issue resolved? Any update from Cisco TAC?

Hi,

a TAC engineer was able to resolve the issue. It involved restarting a number of services.

If you know, can you share the services name or details 

[andreasd1]

TAC told us not to attempt restarting services by ourselves if the issue persists. For the record, the resoution summary is:

"Removed the syslog server from the activities page and restarted related services (daas-runtime, dna-event-runtime, dnacaap-app-services, dnacaap-runtime). - Re-added the syslog server and triggered events to confirm resolution."

did they refer to any known bug?

[andreasd1]

Unfortunately no

Thank you sir, for share the information

Yes, the syslog server have not changed.

Is this working before and   broken after upgrade ?

check DNAC Logs

Not working at all after adding a new event notification.

I've started a TAC case. Hopefully TAC will get it sorted.
