Splunk for Cisco Network Devices

Hi All

We currently have splunk installed, and have a fleet of cisco devices feeding syslog to it. This includes: Datacentre Switches, Switches, routers, firewalls, waas optimisers etc.

Now splunk has already shown it's value, I was just wondering what if any apps are out there that people can recommend?

I've had a look at splunk apps. I was wondering what apps other people are using to better present the cisco syslog coming into splunk.

thanks
