Hiding (filtering) a specific user from reporting in Cisco ISE

I ran into an interesting problem preparing for an 802.1x deployment – the authentications report in Cisco ISE was full of all the network devices checking to make sure ISE was still available (health checks). As seen below the load balancer’s keep alive fill the logs pretty much on their own, imagine trying to troubleshoot a login issue!1 YUCK!

Something else I found interesting that my Google Foo (or knowledge of ACS and how to filter out a certain user) was no match for trying to find a solution for my issue. Because of this, I decided a quick how-to on this would be helpful (I can’t be the only person who will want to filter out such an annoying problem).

First Navigate to Administration > System > Logging:2

Once in the System Settings for Logging, navigate to “Collection Filters”:3

At this point, the rest is pretty straight forward. But for completeness I am going to finish the whole process, so click “Add”:4

After that just fill in the type of attribute you want to filter (Username, Policy Set Name, NAS IP Address, Device IP Address, or MAC Address), the Value for the selected attribute, and the Filter Type (Filter All, Filter Passed, FIlter Failed, or Bypass Suppression [with time limit]). Finally, click “Submit”!


For me, it made the most sense to filter the username used for the monitors, and to only filter on passes for that username. This allows me to use the least amount of filters, and if a health monitor fails for any reason will show up in the reporting still.

Final result (don’t mind the old logs, I was too impatient to wait for them to clear):


Happy troubleshooting!
