I want to schedule a build every day at a particular time say 4pm.
And hence I have set up the build periodically to :
H 16 * * *
I am noticing that the build either doesn't get triggered at the scheduled time or else gets triggered at a random time , ( 4 hours prior to scheduled build)
I want to understand how scheduling works for the build to understand why is it not triggering build at the intended time.
I suspected that master node would be in a timezone other than what I want but that is also not the case.
Inspite of setting timezone as below:
TZ=America/Los_Angeles
H 16 * * *

I want to schedule a job to be launched every 15 minutes within 2:30 ~ 4:30, I had to use multiple lines to achieve that. But as a matter of fact, the job was not evenly scheduled during the period. Is there any way to gracefully solve it?
H(0-29)/15 4 * * *
H(30-59)/15 2 * * *
H/15 3 * * *
It seems jenkins can spread evenly the job in each of above period, but it can't do it making period as a whole period.
I have a job that is configured to schedule and run a job periodically using the following schedule:
01 14 * * 1-5
For some reason, the job is triggering twice every day at the same time. I cannot work out why it is triggering twice. I suspect two possible issues:
The Day of Month (DOM) and Day of Week (DOW) is contradicting
The fact that there are multiple spaces after each column might be confusing Jenkins
Questions
Am i correct that the above says the job should run daily at 14:01 UTC?
What is the significance of the last field? If the fourth field (day of month) specifies * meaning every day of the month, what would be the purpose of the last field (Day of Week)?
What would be the behaviour if i had something like this (where DOM and DOW contradict)
01 14 * * 5
I currently have a Jenkins job that is scheduled to run every 30 mins every day. It is configured as this: H/30 * * * *
I'd like to also tell the scheduler to run every 30 mins except from 2-3am. Is this possible? I can't seem to find exclusions in the schedule documentation.
I think I figured this one out after all.
H/30 0,1,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23 * * *
You need to explicitly set the hours by which you want the job to run, so in the csv list add all hours, except for 2 to keep tests from running between 2am and 2:59am
I am trying to write a query for all builds, but failed to understand the column [ScheduleTime] in the table [tbl_Schedule].
SELECT bd.DefinitionName 'Name', s.ScheduleTime 'ScheduleTime', s.ScheduleTime/1800 'Hour'
FROM [TFS_FTPDev].[dbo].[tbl_Schedule] s
inner join [TFS_FTPDev].[dbo].[tbl_BuildDefinition] bd on
bd.[DefinitionId]=s.[DefinitionId]
where ContinuousIntegrationType in (8,16)
order by s.ScheduleTime asc
If I divide by 3600, I get a sensible data, but it is not valid for all my builds... i.e. Build1 and build2 are scheduled for 13:00 for some days....
name ScheduleTime Hour
build1 43200 12
build2 43200 12
build3 68400 19
build4 77400 21.30
build5 79200 22
build6 82800 23
build7 84600 23.30
build8 84600 23.30
build9 84600 23.30
and the mapping is:
when 84600 then 23.30
when 79200 then 22
when 77400 then 21.30
when 68400 then 19
when 43200 then 12
UPDATE: [Using TFS API]
And this is the API results for a manually triggered/scheduled build...
And this is the subset of results
Have you taken a look at the QueryBuilds method in the TFS Build API instead of reading from the database (which is unsupported)?
The documentation for ISchedule.StartTime Property says
Gets or sets the time as the number of seconds past midnight
So you should divide by 3600 to get the starting hour, the remainder divided by 60 is the starting minute within the hour.
Am I missing anything?
I'm not really sure what you are asking but if you use 3,600 (60 seconds x 60 minutes) you get values as expected.
00:00 = 3600
00:30 = 5400
04:00 = 14400
05:30 = 19800
23:00 = 82800
Your question regarding why some have schedules while being manual builds can be replicated by:
create a build definition
Schedule it
Clone the build definition
Rename it and before saving change the trigger type
Even though this build has never been scheduled it still contains a scheduled time
I would therefore suggest the builds that you are enquiring about have actually been cloned from another build and then the meta data changed, scheduled time seems not be cleared when a build is changed from scheduled to Non Scheduled. either that or at some point during their history they have had a scheduled time set, which has since been changed
I want to execute a python script once in a day at say 1 PM.
I tried using * 13 * * * but the script did not execute automatically.
You should use the Build periodically option as below:
H(0-6) ****
you should use the hours option **** means every day in every week of every month of every year during 0-6 hours this worked perfectly for me
Answer :
H(0-10) 13 * * *
How do you know it didn't execute? Normally it will send a mail to the user account authorised to run the script - look under /var/mail/$ACCOUNT and you should see if it ran, but failed...
I hope you are trying to run the build at 1 PM every day. You can use the below in this case and try.
0 13 1-31 1-12 0-7
