contingency table cell values

"daysago=5 | ctable host date_wday" produces a table with hosts on rows, dates on columns, and total message count in the cells, but takes a while as it must go through all the logs and count them. I have summary index records with fields orig_host and daily_count, but how do I get it into the same format as above?

More generally: it'd be handy if ctable took an optional argument to indicate what values were put in the cells, eg "daysago=5 index=summary search_name=daily_count_by_host | ctable orig_host wday value=daily_count". It'd also be nice to be able to control the sort order of rows and columns, eg via a preceding sort. Maybe there is already a way to do this?

Thanks for any help!

First note that ctable is roughly equivalent to chart. The following two give the same results, except for the limit in series that will be shown:

... | ctable x y
... | chart count by x y

In your case, you don't want the count of summary events but rather the sum of the daily_count field. So your search will be:

daysago=5 index=summary search_name=daily_count_by_host
| chart sum(daily_count) by orig_host wday

eggcellent - thanks! hmm, the cli behavior is unexpected - eg pipe to less shows incomplete results. i'm aiming for a cli that shows top N chatty hosts - any pointers on that? (i don't know if i should submit a separate question)
