Below is the syntax I have tried with 0 30 0 * * ? or 0 30 1 * * ?, which should run at 12:30 or 1:30 midnight respectively.
Also I have tired running the flow with cron in nifi for every 20 minutes duration, it worked perfectly.
But we want it to be run, daily once at particular time as mentioned above example (0 30 0 * * ? or 0 30 1 * * ?).
But it is not working. can anyone please guide.
Thanks.
Ahmed,
You have use below cron expression to run processor daily at 12:30PM
0 30 12 1/1 * ? *
Check it here:http://www.cronmaker.com/
Just now I tried like for time 19:10 below:-
0 10 19 1/1 * ? *
It worked for me.
You can make cron scheduling for NiFi using the link CronMaker.
The simplest form:
0 30 1 * * ?
This is actually an example from Nifi documentation:
https://nifi.apache.org/docs/nifi-docs/html/user-guide.html
And here's a complete tutorial on cron:

I am currently using the cron 'cron(0 9 ? * MON-FRI *)' in AWS cloudwatch but it seems to run it continuous every minutes for that hour, what am I doing wrong?
I wanted it to run every weekday (mon-fri) at 9am on the dot.
I would try 0 9 * * 1-5
You can debug it here for instance: https://crontab.guru/#0_9_*_*_1-5
You should use -> 0 9 ? * MON-FRI *
I want to schedule a method to run every 24 hours and with the settings I have it is executing every 24 minutes.
I have referred below URL's which has different suggestions
Link 1 suggests <second> <minute> <hour> <day-of-month> <month> <day-of-week> <year> <command>
Link 2 suggests minute hour day(month) month day(week)
Below are the cron settings put in the application.yml of my Spring Boot application.
cron:
job:
expression: 0 0 23 * * ?
Could someone help on what are the correct source of information and what can be the settings with the requirements at hand.
0 0 * * *
This will run job at 12:00 am every day
If you run the scheduled job in spring the record must be as mentioned in first link:
0 0 23 * *
This will run the job at 23:00:00 every day
0 0 0 */1 * *
I am using this command to run once everyday. You can also use
0 0 0/24 * * *
to run once every 24 hours
I'm tring to run a function every 10 minutes.
According to the documentation, it is stated that e.g ("0 0/5 * * *?") Runs every 5 minutes since the program started, but why when I change 5 by 10 ("0 0/10 * * *?"), the function does not run every 10 minutes e.g (10:10 - 10:20 - 10:30)
Is it really me who misunderstands the Cron Expressions or the syntax is wrong.
here is typo in :
"0 0/10 * * *?"
should be
"0 0/10 * * * ?"
here is the useful resource CronMaker is a utility which helps you to build cron expressions. CronMaker uses Quartz open source scheduler.
I have a problem with Magento cron expression. It works fine with minutes:
<crontab>
<jobs>
<namespace_module_cron>
<schedule>
<cron_expr>*/15 * * * *</cron_expr>
</schedule>
<run>
<model>namespace_module/observer::myMethod</model>
</run>
</namespace_module_cron>
</jobs>
</crontab>
But it doesn't work when I set hours:
<cron_expr>0 1 * * *</cron_expr>
or
<cron_expr>0 */1 * * *</cron_expr>
I tried different time settings in admin panel. For now there are:
15
1
60
120
120
3000
P.S. Magento ver. 1.7.0.1
Update
I left every hour job (0 */1 * * *) for a day and it actually runs:
14:15
16:15
21:15
22:15
03:15
04:15
I've figured out what was wrong. It were settings (System/Configuration/System/Cron).
When I set up "Schedule Ahead for" to 60 it started to work properly (every hour and every day schedules).
For now schedule in database is appearing at 15:20 when I need to execute it 16:00.
Settings:
Generate Schedules Every: 15
Schedule Ahead for: 60
Missed if Not Run Within: 60
History Cleanup Every: 120
Success History Lifetime: 120
Failure History Lifetime: 3000
If you have the same problem, you should pay attention to first two settings: "Generate Schedules Every" and "Schedule Ahead for"
For every hour at 0 minutes (00:00, 01:00; 02:00 etc), you must put :
<cron_expr>0 * * * *</cron_expr>
I have defined the corn job like this.
03 16 * * *
when your cron.php runs at 16:02 o'clock then it will create only an entry about this cron job in database table cron_schedule and it will not run the cron job.
To run this cron job i need to run cron.php twice,
means after creating an entry in table you should run cron within 15 minitues, otherwise that entry is ignored.
So to run the cron job, you should run the cron.php periodically.
my cron job run every day at 16:03
and i run cron.php every after 10 minute
I know this is old, but it may still be relevant as I encountered something similar. How often is your cron.sh scheduled to run on your server. If the scheduler is set to every 60 minutes and it runs on the hour (12pm, 1pm 2pm... etc) and your Scheduled ahead time is set to 20 minutes (default i think), and your magento cron expression is, for example, 30 * * * *, or every hour on the half hour, you job will never run. Your cron.sh will only set up magento cron jobs up to 20 minutes ahead, and so the 12:30 job will not get scheduled, but since magento's cron.sh is set to run on the hour, it will never get scheduled. I suspect your original problem is something similar, because adjusting the "scheduled ahead" time past the time the magento cron should be scheduled fix an issue like this. Just something to look out for as well.
I want to set a cronjob entry that runs a script every 30 minutes from 9:00 to 18:00 but I do not want it to run at 18:30. The script should run for the first time at 9:00 and for the last time at 18:00. Is this possible?
Yes, it is possible; cron itself can't solve the task, but it is possible using additional shell command:
*/30 9-18 * * * root [ $(date +%H%M) = 1830 ] || your_command
your_command will be executed if and only if the current time is not equal to 18:30
You might need to have two entries:
0,30 9-17 * * * /script
0 18 * * * /script
Alternatively, you could modify your script to check if it's close to 18:30 or not, and exit early if so.
