Hi,

We Need to extract a Duration value from the message field (e.g. Duration="10.400")  
We Need to summarize this value for a Special time period and we need to multiply the total summ for example with 0,3. How can a value be extracted, added to the new field (e.g. Conference\_duration) and this value be used for other operations like multiplying it with a number to get for example a Price for the Duration

Any idea? I am Looking for a good Training to learn the filtering language

For Example in Splunk this would look like  
onference has been stopped. | eval total\_hours=round(Duration/3600, 3) | eval cost=round(total\_hours\*$kostenfaktor$,3) | chart sum(cost) as Cost by Service\_tag
