ISE Logging

netmart — Mon, 31 Mar 2025 14:04:36 GMT

Hello,

I wanted to filter Cisco ISE Logging Activities by authentication, authorization, and accounting.

So far, I've been able to filter by Accounting, but not the other two.

In Cisco ISE Logging, TACACS Accounting has been linked to splunk server.

And I am running the following filter:

<ISE Server> AND "CISE_TACACS_Accounting" AND Type=Accounting | stats count(_time) by _time.

Any advice is much appreciated.

Thanks.

Why not the other two? What happens when you try?

In Cisco ISE Logging, TACACS Accounting has been linked to splunk server.

What does it mean to link to a Splunk server?

And I am running the following filter:
<ISE Server> AND "CISE_TACACS_Accounting" AND Type=Accounting | stats count(_time) by _time.

Have you tried adding the other types to the query?

<ISE Server> AND ("CISE_TACACS_Accounting" OR <<name for ISE authenticaton>> OR <<name for ISE authorization>>) AND (Type=Accounting OR Type=Authentication OR Type=Authorization)

BTW, there's little value in counting events by timestamp.

Hi @netmart

I dont have any ISE events in Splunk to verify the exact SPL for this, however your could start by looking at doing your stats by "Type" and then limit this in your SPL once you know which you want.

<ISE Server> Type=* | stats count by Type

This is a high level search but might get you started.

If you're able to provide examples of the events I'd be happy to update the search accordingly.

Thank you @livehybrid

Just one more information.

In Cisco ISE TACACs live logs I do have the option for filtering both:

Authorization

Authentication.

However, in splunk I also tried to filer for Authorization and Authentication, but only was able to filter for type Accountings.

Thank you.

For some reason I am still only able to filter for type accounting. At this point, I am wondering whether it is an issue with splunk or ISE does not send this information as part of syslog.
