Custom Discovery Schedule with a Condition Script

[Jim Coyne]

The "Run" choices we have when setting up a Discovery Schedule are:

• Daily
• Weekly
• Monthly
• Periodically
• Once
• On Demand

We would have to create multiple schedules in order to run a Discovery every weekday or just weekends.   Or do we? 

It may not be obvious, but because the Discovery Schedule table is a subclass of the Scheduled Job table, we have access to the Conditional checkbox and Condition script fields.   By adding those fields to the Discovery Schedule form, we can now use a script to decide when it should run.   So for example, set the "Run" field to "Daily", check the "Conditional" field and add the following script to the "Condition" field to run a Discovery on weekends only:

(function() {
  //run on weekends only
  var day = new Date().getDay();
  return (day == 0 || day == 6);

})();

Skip Sundays:

(function() {
   //skip Sundays
   var day = new Date().getDay();
   return (day != 6);

})();

This script for Monday to Friday:

(function() {
  //run Monday to Friday
  var day = new Date().getDay();
  return (day != 0 && day != 6);

})();

This one for Monday, Wednesday and Fridays:

(function() {
  //run on Monday, Wednesday and Fridays
  var day = new Date().getDay();
  return (day == 1 || day == 3 || day == 5);

})();

So what happens is the Discovery Schedule will in fact "run" every day at the specified time, but if the condition fails, the job ends without actually kicking off a Discovery.

Absolutely.   Sorry for the oversight on my part.

No problem.   Thanks!

Just setting this answer as correct as the actual thread was not meant as a question and it cannot be changed because it came from the original Community site.

Jim,

Is it possible to put a time in the script to run it at 8am, 12pm and 3pm?  Here is my script.

(function() {
//run on Monday, Wednesday and Friday
var day = new Date().getDay();
return (day == 1 || day == 3 || day == 5);
})();

Jim,  I am trying to setup a scheduled job to create a requested item on the 2nd and 4th Tuesday.  Can this be done in one scheduled job or would I have to create 2 separate scheduled jobs and use the conditional formatting?  Can you provide some help on the conditional script I would need to use to accomplish this?  Any help is greatly appreciated.
