Hi rene847, the main question here is: where and how to find those events? Let's assume your events are in an index called network and the protocols are identified by the field protocol , a simple search like this will get the expected result: index=network protocol=* earliest=-7d@d | timechart span=1d count by protocol limit=10 This will search in index network all events which contain a field called protocol over the last 7 days, count each protocol per day and return the top ten results over the time. If you need further assistance, please add more detailed information to this question like where to find the events, what do the events look like, what exactly is the expected result, what have you tried so far? Hope this helps ... cheers, MuS ... View more

Hello, You'll have to be very clear about your use-case and details to get a good response. I am guessing that: 1. All system and application events coming from an unnamed Linux host are being sent to Splunk via syslog. 2. You want to parse the syslog stream and separate application events from system events by index. 3. If possible tag system and application events with a unique sourcetype. If that's the case, you would: 1. Get the events to Splunk the same way you already are, but add a sourcetype in the inputs.conf 2. On the main Splunk instance (or indexer) write a props.conf/transforms.conf combination to filter the destination index based upon the sourcetype and a regex match. The setting you want is the Metadata:Index to change the destination index. There are partial examples several places in Answers, such as: here. ... View more
