How to create a report of distinct Error Descriptions and count of each for each hour of a day?

[runiyal]

We are getting a number of different errors in the log file.

Requirement is to get a report of distinct Error Description and count of it for each hour of a day...so something like this

Error Desc 1 2
NO Policies for 100 50
Folder not found 50 25
File not found 150 30
Details can be found in the server logs 200 50
Duplicate child name not allowed 180 40

With little information provided, try something like this (runs for today time range)

your base search earliest=@d | eval Hour=strftime(_time,"%H:00") | chart count over Error_Description by Hour
