The Device Server (devsrvr) is responsible for some communication between Dataplane and Management Plane.

It receives and handles URL filtering requests from the dataplane and is responsible for pushing configuration down to the dataplane

if it's running really high you may be processing a lot of URL filtering lookups

Thanks for your answer.

I don't know how to check usage a lot of URL Filtering lookups.

Please let me know it.

you could try below commands:

on the management plane
> debug device-server pan-url-db show-stats
> debug device-server bc-url-db show-stats

on the dataplane
> show running url-cache statistics
> show counter global filter delta yes | match ur

if this doesn't indicate a large volume of URL requests you could enable debugging and read through the logs to see if you can pinpoint something odd, but at that point i'd probably recommend you reach out to TAC and provide them with a techsupport file to analyse the issue

> debug device-server on debug
> tails follow yes mp-log devsrv.log
when done
> debug device-server on info
