So I used the purgewhenfull filter (as suggested in the faq/readme :) to delete events when the disk gets over 90% full.

I'm confused about the difference between a filter that is saved and when it is executed.

Does the filter stay and get executed indefinately, or is it a one time shot?

If it's a one time thing, do most people just run a cron job to trigger the filter?

Does the filter apply only to one monitor or can it apply to all of them?

And the readme warns about limiting what is returned from the filter, otherwise all events would be deleted. Am I reading that right? How do I avoid this problem?

Thanks!

It runs every time at the freq you have your filter reload set to

execute it manually will just return the results, when you save it you can select, delete email upload etc. Basically every time the filter is executed all the results returned will have the selected option performed on them, ie delete

If it's a one time thing, do most people just run a cron job to trigger the filter?

No we leave zmfilter and zmaudit to do it for us, but you cant run one time filters this way

Does the filter apply only to one monitor or can it apply to all of them?

Depends on how you set the filters

And to check your not wiping it all away, thats why you check the results. Whatever is returned would have been deleted/uploaded/emailed etc
