I've configured CloudWatch events to run every 1AM Myanmar time and 8AM Myanmar time as follows:
run 1am Myanmar Time
30 18 * * ? *
run 8am Myanmar Time
30 1 * * ? *
Unfortunately, CloudWatch is not running on those certain times ? Please let me know if my UTC configuration time is correct?
Your scheduled expression is correct, but I can see the status as Disabled,
Please Enable and try.
On CloudWatch screen: See right top for Actions drop down,
Actions > click 'Enable'

I would like to schedule a trigger for a AWS Glue job using CloudWatch schedule expressions. The requirement is to schedule the trigger to run every 3 hours between 8am and 6pm. I don't see any possible option of configuring this. Using the following expression, I can only schedule it between 8am and 6pm, but how can I configure the rate to be 3 hours instead of every hour?
cron(0 8-18 ? * * *)
The desired rate is to scheule it to run at 8am, then 11am, then 2pm, then 5pm.
This should work for you:
0 8-18/3 ? * * *
I can't figure out how to create a job that ends at a specific hour and minute
If you break your cronjob into two, it would look like:
* 8-19 * * * command
0-30/1 19 * * * command
first line runs every minute from 8-19, and second line every minute from 19-19:30.
Cron triggers are not quite suitable for these types of schedules. If you do not insist on using a Cron trigger, I recommend that you check the Daily Time Interval trigger that is designed for use-cases such as yours. I am attaching a screenshot of a Daily Time Interval Trigger configuration for your use-case.
If I wish to run my function app at 11.15 PM to next day 1.15 AM(That mean MONDAY 11.15 PM start and TUESDAY 1.15 AM will end) and it will trigger every minute during this time.
Can anyone help me to write this CRON expression?
The timer triggers are designed for a single repeating interval. The only way to do this completely within a Function is to run the trigger once per minute, then abort if the current time isn't in the desired target time period.
Alternately, put your logic into an HTTP trigger configured to act as a webhook, then use an Azure scheduler to configure start and stop times and intervals.
You won't be able to use the scheduler free plan since it can only run once per hour, but the standard plan can run once per minute. Scheduler pricing here.
You'll have to do this in three lines I think,
15-59 23 * * *
* 0 * * *
0-15 1 * * *
This will run it from 23:15-23:59 then 00:00-00:59 then 1:00-1:15
In AWS glue service there is an option to trigger job by custom CRON expression. Before i used this (0/2 * * ? *) cron expression to trigger job for every 2 hours.
Now I need to change the cron expression to trigger every 90 minutes, i.e for every 1 and a half hour. I tried with many cron expressions but that did not triggered for every 90 minutes. Even if i give for 90 minutes, it trigged for every 1 hour.
Can anyone help me out by providing the correct cron expression to trigger job for every 90 minutes ?
You can use the following pattern which was based on Bill Weiss' answer on Server Fault. It was modified to comply with the unique syntax AWS uses (reference here):
0 0-21/3 * * ? *
30 1-22/3 * * ? *
You'll have to define two separate Glue Triggers to accomplish this, each with the same job settings.
If curious, the syntax reads:
Run every 0th minute for every third hour for 0-21 hours
Run every 30th minute for every third hour for 1-22 hours
When I go to configure a Schedule in the Azure management console, I'm only given the option of scheduling with an absolute end date/time (or never ending) and an interval.
So I can't, from this UI, schedule a job to every 30 minutes run every day from 8:00 AM to 6:00 PM only (i.e. don't run from 6:01 PM to 7:59 AM). Windows Task Manager and all other schedulers (cron, quartz) I've used before support the behaviour I want.
Is type of schedule supported at all in Azure, e.g. through the API or a hackish use of the Portal HTTP/JSON interfaces?
You can use the built-in scheduling which is more flexible than the Azure one.
You can learn more about how that works from this blog post http://blog.amitapple.com/post/2015/06/scheduling-azure-webjobs/
The summary: create a file called settings.job that contains the following piece of json
{"schedule": "cron expression for the schedule"}
in your case the cron expression for "every 30 minutes from 8am to 6pm" would be 0,30 8-18 * * *
so the JSON you want is
{"schedule": "0,30 8-18 * * *"}
Keep in mind that this uses the timezone of the machine, which is UTC by default.
This is something you need to implement in your WebJob. I have a similar issue in that I have WebJobs with complex schedules. Fortunately it isn't hard to implement.
This snippit gets your local time (Eastern from what I can tell) from UTC which everything is Azure is set to. It then checks if it is Saturday or Sunday and if it is exits out (not sure if you need this). It then checks whether it is before 8AM or after 6PM and if it is exits out. If it passes both those conditions the WebJob runs.
//Get current time, adjust 4 hours to convert UTC to Eastern Time
DateTime dt = DateTime.Now.AddHours(-4);
//This job should only run Monday - Friday from 8am to 6pm Eastern Time.
if (dt.DayOfWeek == DayOfWeek.Saturday || dt.DayOfWeek == DayOfWeek.Sunday) return;
if (dt.Hour < 8 || dt.Hour > 16) return;
//Go run WebJob
Hope this helps.
