I need to get the exact time when the build has triggered(build periodically option currently using). Because of the configuration only 3 tasks can run in parallel. Consider 3 tasks are running in parallel now. So the executor will be putting the next task in Waiting for the next available Executor state. So I need to access this waiting time or exactly when it is started as date means when its triggered.
I have used Build Timestamp Plugin also. But no use. It is giving the time when the build steps has started. So can anybody help me do this? Thanks.
I have found one solution which I'm going to share now. If anybody is in the same situation, this might help them.
build_details = get('http://localhost:8080/jenkins/job/<jobName>/api/xml?tree=builds[id,queueId]&xpath=//build[id=<buildId>]')
queueId = build_details['build']['queueId']
queue_details = get('http://localhost:8080/jenkins/queue/item/<queueId>/api/json')
job_queued_time = Time.at(queue_details['inQueueSince'] / 1000.0).to_time.utc
Note: I've posted pseudo code, not a full solution. You have to port it to your language. <jobName>, <buildId>, <queueId> are variables, please replace them.
Here, localhost:8080 is same for everyone because, that is going to run in Jenkins machine itself. Mostly my solution works for single node Jenkins(i.e. No master-slave architecture). I haven't tested it in master-slave though.

My dataflow batch job not end in 5 hours. still canceling.
Im running this type of job in scheduler every 10 min.
normally, it is finished in 10 min.
but it tooks over 5 hour!
My job is
2018-08-26_13_30_17-1172470278423820020

Workflow failed. Causes: The Dataflow job appears to be stuck because no worker activity has been seen in the last 1h. You can get help with Cloud Dataflow at https://cloud.google.com/dataflow/support.
Generally The Dataflow job appears to be stuck because no worker activity has been seen in the last 1h can be caused by too long setup progress. Just increase worker resources (via --machine_type parameter) to overcome the issue.
In my case I was installing several dependencies that required building wheels (pystan, fbprophet) and it took more than an hour on the minimal machine (n1-standard-1 with 1 vCPU and 3.75GB RAM). Using more powerful instance (n1-standard-4 which has 4 times more resources) solved my problem.
It is possibly not the case if there is single job stuck but may help someone else getting the same error.
Such situation can happen in three major cases:
a) Some task takes more than an hour to process.
b) Some task got stuck processing.
This is generally caused by transforms that take too long to process, or enter blocking state.
Best way to debug is to check for previous logs and see if there were any errors, or unexpected state. It seems that you have tried to re-run the job and it still failed. In this case you can add extra logs to the step that got stuck and see which data it got stuck at.
c) There is failure on Apache Beam / Dataflow side.
This is a rare case. Please, create support ticket if you believe this is the issue.
I just recovered from this issue.
As mentioned in other responses, this error is due to long setup progress. This is probably the incapability of pip to resolve the dependencies in the setup.py file. It does not fail; it tries in vain "forever" to find suitable versions leading to a timeout.
Recreate the environment locally using the necessary packages.
Mark the versions that satisfy the dependencies.
Define these versions explicitly in the setup.py.
I don't know why this worked but updating the package dependencies in setup.py got the job to run.
dependencies = [
'apache-beam[gcp] == 2.25.0',
'google-cloud-storage == 1.32.0',
'mysql-connector-python == 8.0.22',
]
I am using Jenkins to deploy changes to a system which manages and runs lots of different jobs which are scheduled daily. We have a staging setup which does not write to the real database, and a production setup which does.
The Jenkins flow I would like to have a happen when a change is pushed is this
Run checks.
Deploy to the staging system.
Wait 24 hours.
Check logs to make sure that the staging system has not had any errors in the last 24 hours.
Deploy to the production system.
There could be more than one of these builds running concurrently at any time - eg. I push changes at 11 am, they are deployed to staging. At 5 pm I push more changes and they are also deployed to staging. The next day at 11 am the first set of changes only are deployed to prod. At 5pm that day the second set of changes are deployed.
Now, I have managed to build a system which does this, by using the Build Flow Plugin, and creating a job called wait_one_day which runs sleep $((24 * 60 * 60)) in a bash shell.
This doesn't seem like the most elegant solution, and has the disadvantage that I am tying up two Build Executors for 24 hours (one for the build flow job, and one for wait_one_day), each time we make a change.
Is there any better way of doing this, or any plugin which is designed to help with this process? Can a Jenkins job schedule another Jenkins job to run as a one-off?
I would equally be happy to hear about an alternative approach to solve the same problem if anyone has any suggestions or constructive criticism of my design.
There was similar SO question recently that I answered, although I'm not sure that my answer there exactly fits your scenario.
You could potentially dynamically create a job that does steps 4 & 5 which would run periodically every 24 hours. The catch here is that you would actually only run this job once, and have a build step in that job that deletes itself (groovy code or shell script). It would be easy enough to create a deactivated template job that you could just clone and then modify for the particular task. An intermediary job would be necessary which would trigger upon completion of any job that runs steps 1 and 2. The intermediary job would then create the temporary job from the template.
Alternatively, you could create some sort of handler, either within jenkins or external that would run off of some properties file or database containing the scheduling for when jobs need to be fired off. Granted, if you are going to go the route of writing a handler, you might consider putting in a little extra effort and writing a jenkins plugin...
i know there are several issues with a topic close to this one. But as fas as I searched i did not found a thread/question with the same topic.
So here is the situation:
On our Jenkins Server we a many build jobs (maybe a few hundred). Some of them running on Slaves, some on the master. Now i was asked to change settings of some of them (lets say 50), so the have project based security and I had to change the slave server they are running on. Before they ran already on a Slave, but a different one.
The Problem:
In the beginning everything went fine. I changed the settings ob several jobs quick and startet to change the settings of the next job. But after some time the configuration settings began to load slower and slower. First it were a few secounds(after 10 Job), then a few more secounds (after 20 jobs), then like one minute (after 30 jobs) and now several minutes (after 40 jobs). I open every settings page in a new tap and close the tab once I finished my configurations.
My Question:
Why does it take Jenkins so long to open up the configuration page? Especially because in the beginning there was nearly no loading tim and now after I changed a few jobs i have to wait minutes for it. What could be the reason?
You need to see in the first step what is configuration of this new slave,
Issue can be memory based, so on master instance check the memory usage and check the java process, can be done with strace -p <PID> depends on your environment.
Instance can be slower due to memmory usage which is in the most cases.
We've inherited a set of Jenkins builds. They all seem to start 90-100 seconds after the desired time. For example, a build with a schedule of */5 * * * * starts at :01:37, :06.29, :11:43, etc., instead of :00, :05, :10, etc. that I would expect.
There are a few builds set to run at /5, but they are all delayed and anyway only last a few seconds each.
I see a global 'quiet period' setting of 5.
The system as a whole does not seem busy. There are usually idle executors, and often nothing at all is building.
For most of the builds this isn't a concern, but there are a couple that we would like to make as precise as possible.
Is my expectation wrong? Is there a config option I'm missing? I should add that I am new to Jenkins and may be missing something obvious.
Thanks
We did not find the cause of Jenkins jobs starting late. We hacked up a workaround by having Jenkins start a script on the remote server that sleeps until the desired time. This creates a new problem by tying up a Jenkins executor for several minutes, so we have the remote script spawn a wait task and then return to Jenkins immediately. This creates another problem in that the output of the remote script is lost because when it completes it has no connection to Jenkins anymore. We get around that by having the remote script write its results into a tmp file, and returning the results of the previous run.
So we have a seriously hacked-up solution that actually works fine for our purposes.
We updated Jenkins from 1.492 to 1.565 and the problem went away. Jobs now start within a few seconds of the expected time.
I have 2 jobs in Jenkins: QA and Dev.
In Dev job I checked "Build after other projects are built" option and set project name = QA so that QA job will be built after Dev job is built.
But in my particular situation I need that QA job started building in 5 mins after Dev job is built. How can I do it? maybe I can add some build step with some data to add this delay ?
TIA,
Anna
There is a "Quiet Period" option in the Advanced Project Options available. You can enter a value of 300 (its in seconds) to delay the start of the job by 5 mins.
If you're using the REST api, you can add a url get value like this:
http://jenkins/job/jobname/build?delay=4
That will delay 4 seconds and start the job.
I know the topic is quite old but in case sameone else is looking for an answer here it is.
When using parametrized build remember to escape "&". You can replace it with: "%26" or put the whole URL in quotes. It will work. Please also remember to use delay as first parameter.
To make it simpler with out worrying about trigger from URL using delay, there is a Jenkins plugin which helps to schedule the job on the fly with as much as delay you need (configurable when ever you are running build and supports parameterized builds as well).
