Add "limit_execution" parameter in rule config

[adrienyhuel]

Since you pulled elastalert from yelp/master, there is an useful feature included in elastalert : we can limit rule execution time with a cron expression (ie : by example, make a rule run only during working hours).

See : Yelp/elastalert#492

Can you add a input box in preaco, where we can set this parameter in rule config ("limit_execution") ?

Related: would be great to have a per rule configuration for run_every parameter.
Added to master elastalert just recently:

Yelp/elastalert#497

It is recognized that limit_execution has the following settings. Is there any?

limit_execution: "* 02-03 * * *"

Do you feel that the input fields and default values for Minute, Hour, Day, Month, and Week are all "*"?
If not, please tell us what kind of UI you want.

Yes, limit_execution seem to be a cron syntax.

The default value should be None, in order to not activate this function.
See : https://github.com/Yelp/elastalert/blob/1dc4f30f30d39a689f419ce19c7e2e4d67a50be3/elastalert/elastalert.py#L1253

For UI, basic string could be OK, as most of us understand crontab syntax.
For an enhancement, maybe you could use some graphical component, like https://github.com/karoletrych/vue-cron-editor.

@adrienyhuel

thank you for your answer. I didn't know vue-cron-editor. We are planning to add a setting screen using vue-cron-editor.
