The averaging function (avg) calculates the average value of the numerical field being evaluated within the time range analyzed.


  • avg(numerical_field)


  • Creates field named _avg


... | avg(request_received) group by hour

Sample log message:

Aug 2 04:06:08 : host= local/ssl2 notice mcpd[3772]: filesize=20454: diskutilization=0.4 : 01070638:5: Pool member monitor status down.

Example based on sample log message above:

| parse "diskutilization=*" as disk
| avg(disk) group by _sourceCategory
| sort by _avg

This query finds all messages that contain the term disk* and parses out all that have a diskutilization= value. It then extracts the value of diskutilization into field disk. The next statement finds the average disk utilization by category. Effectively, it gives you a picture of how your hosts are doing on average based on categorization of log sources you’ve chosen.

Note that when you calculate the average of more than one field, you must create an alias using the as operator to rename the average fields. See this example:

| kv "HandleCount", "ThreadCount"
| avg(HandleCount) as avgHandleCount, avg(ThreadCount) as avgThreadCount
