Help for configuring Health Rule schedule

[Rakshit.Patki]

I have created a custom extension that captures the status of the Scheduled Job (e.g., Ready, Running, Others) and sends the data to AppDynamics as 1, 2, etc. respectively.

Do we have any feasibility of configuring Health Rules to accommodate the following conditions:

TaskName	Triggers
Failure_PushData_ToWellnessCore_CRON	Start at 12 AM and execute every 3 Hrs
PushToWellness fromDbtoConsoleApp	Start at 5 PM and execute every 3 Hrs
Wellnessdatacron	starts at 12.01Pm and execute every 1 hr
WellnessFailureCRON	9am, 12am, 3pm, 6pm, 10pm, 1am, 5 am
NoiseDataSyncCron	Start at 11Am and execute every 1hr
NoiseWebhookProcessor	Start at 11Am and execute every 2hrs

I tried configuring Cron with Start time as 0 17/3 * * * and End time 59 23 30 4 * as to accommodate "Start at 5 PM and execute every 3 Hrs " condition as a Health rule schedule but I am getting error as Error creating schedule: Test. Cause: Unexpected end of expression. 

Can anyone help me with this?
