I have developed an time trigger azure function which is set to fired every hour but it is not triggering the function as expected. It's triggering behavior is very strange. I am attaching it's executing logs.
The cron expression for triggering the function is as follows:
0 0 * * * *
Anyone has any idea whats wrong with this?
The expression for hourly schedule is:
0 0 */1 * * *

Can you try below cron job expression,

0 0 * ? * * *
But according to MS documents what you have used is correct. Are you using application insights ?

I am trying to set a CloudWatch schedule event rule that will run on every quarter of year. But I am getting this error
"Parameter ScheduleExpression is not valid".
I tried following Cron expressions
cron(0 0 1 */3 * ?)
cron(0 0 1 */3 ? *)
But not working. Can anyone help in this?
Per AWS documentation
You cannot use * in both the Day-of-month and Day-of-week fields. If you use it in one, you must use ? in the other.
Also the year field does not support the ? wildcard, so your first expression is invalid.
The second one works:
aws events put-rule --schedule-expression "cron(0 0 1 */3 ? *)" --name so-test1
{
"RuleArn": "arn:aws:events:eu-west-1:3333:rule/so-test1"
}
Do you have a space after the closing bracket? That one marked as invalid for me
aws events put-rule --schedule-expression "cron(0 0 1 */3 ? *) " --name so-test1
An error occurred (ValidationException) when calling the PutRule operation: Parameter ScheduleExpression is not valid.
In my mule flow, currently the cron expression in the Quartz component is 0/10 * * * * ? which triggers for every 10 secs. I need to modify my cron job to work with initial delay of 5 secs? How can i accommodate this by just making change to cron expression?
The Quartz component has a Start Delay property in milliseconds
<quartz:inbound-endpoint doc:name="Quartz" jobName="StartFlow" startDelay="5000" repeatInterval="0" cronExpression="0/10 * * * * ?" >
<inbound>
<quartz:inbound-endpoint jobName="myServiceJob" startDelay="5000" repeatInterval="1000">
<quartz:event-generator-job/>
</quartz:inbound-endpoint>
What i should do to run CRON trigger to run now once and follow the expression for Example
trigger that simply fires every 5 minutes.
I have gone through the below post
https://groups.google.com/forum/#!topic/quartznet/GAv10E4TJ50
If you want to make sure your job is run immediately you can set start
time to one day before DateTime.Now, so you change your code to:
CronTrigger trigger = new CronTrigger("trig", "grp", "job", "grp",
DateTime.Now.AddDays(-1), null, "0 0 0 * * ?");
But does the above work for any scenario. like
0 0/5 14 * * ? Fire every 5 minutes starting at 2pm and ending at 2:55pm, every day (if current time is 2:15pm)
Thanks,

What about creating a CRON trigger with a temporary schedule to "trigger the job now" (e.g. 0 * * * * ?) and implementing a JobListener that would update the CRON trigger's expression once the job has been executed for the first time? You can use, for example, a job data map parameter to distinguish the first and subsequent executions in the listener.
If you do not insist that it must always be the same CRON trigger that "executes the job now" and then continues to execute it regularly, then you can use one of the triggerJob methods that both create a temporary on-off SimpleTrigger that is used to execute the job now.
The time at which the trigger's scheduling should start. May or may not be the first actual fire time of the trigger, depending upon the type of trigger and the settings of the other properties of the trigger. However the first actual first time will not be before this date.
So i could able to run immediately by setStartTime
it's strange, i setup corn as
#Scheduled(cron= "0 0/10 * * * ? ")
It did trigger every 10 minutes,
but the issue is task runs each second.
This is what javadoc says :
CronSequenceGenerator
the first field of the cron is for seconds.
I have a cron job that Runs using Quartz.NET.
<cron-expression>0 5 * * * ?</cron-expression>
It runs every 5 minutes as you can see above, but I want it to not run from 5pm on 30/Dec/2013 to 7am on 01/Jan/2014..
Is this possible does anyone know?
Thanks

Exclusion are most easily made with calendars. With calendar you can exclude a set of days, weekdays, time of days or a cron expression from schedule. Calendar is checked always checked after fire time has been determined (is this OK to run?).
You could either chain multiple calendars because you have nasty complexity of passing the year, multiple days and time range on top of that. More readable and understandable solution could be to implement your own fixed time range calendar (implementing ICalendar) that takes end and start time and excludes them.
You could naturally also make your first cron trigger end at 2013-12-30 17:00 and add a new trigger that starts at 2014-01-01 07:00.
Here's a trivial sample utilizing CronCalendar:
var calendar = new CronCalendar("0 * 1 * * ?");
scheduler.AddCalendar("myCalendar", calendar, replace: false, updateTriggers: false);
var trigger = TriggerBuilder.Create()
.WithCronSchedule("0 5 * * * ?")
.ModifiedByCalendar("myCalendar")
.Build();
scheduler.ScheduleJob(trigger);
