Limit rules to certain time during the day

[fberrez]

The idea is to add a new attribute such as limit_execution to enable the alert to certain time during the week using a cron schedule expression.

limit_execution: "'* 10-18 * * 1-5" # activates the rule from monday to friday, between 10am and 6pm.

See: Yelp/elastalert#492

limit_execution was added in elastalert 0.2.0, is it a suggestion to change it?

[fberrez]

Shouldn't the documentation be updated?

@fberrez

There is no rule who has to do it. Can you make a pull request to update the document separately?

I think it was never merged in the master branch, only in a "beta" that never went out. Am I wrong?

@mrfroggg

Beta has been merged into master.

Yelp/elastalert#492 (comment)

I've merged this feature into a new branch, beta, and released it as a new package version 0.2.0b1 available on pypi.

This includes a couple other changes as well, like threading support, but you can now limit rule execution to certain >times of the day using limit_execution using cron syntax. For example

limit_execution: "* 7-22 * * *"
Would mean to only run the rule between 7 am and 10 pm every day.

This feature is still in beta, of course, but you're welcome to try.

Merged all beta changes into master

Right, I found it in the code!
This is something I'll try to test in the next days, I can try to do a quick documentation update on it!
