I have Jenkins running at https://jenkins.example.com:8443. We installed the Prometheus plugin and restarted the instance with no issues.
When browsing to https://jenkins.example.com:8443/prometheus/ I get a 200 but no data is generated. Left the page open and no data generated more than an hour later, restarted the instance, still just a blank page. I have installed the Prometheus plugin on a bunch of other instances with the same exact setup and configuration and those have no issues. Running Jenkins ver. 2.164.1 with Prometheus 2.0.6. I tried setting up logging for the plugin but not seeing any logs being generated either. The Prometheus config has the Jenkins instance configured in the scrape and Jenkins target is up in the targets page of the Prometheus UI. But again, no data is being generated.
Plugin documentation is here: https://plugins.jenkins.io/prometheus/
Try to generate Access Keys in the metrics section and access the url https://jenkins_ipaddres:portnumber/metrics/accesskey you would now be able to view the metrics.
Path to generate the Access Keys:
Jenkins > Manage Jenkins > Configure Systems > Metrics >> Add >> Generate >> Save
Thanks

I have a kubernetes cluster in which I have jenkins and spinnaker pods up and running. I need to implement a logging mechanism which collects and sends logs to splunk server. I chose to do so using fluentd. I have deployed a daemon set of fluentd to run on each node and collect logs from each node and send to splunk server.
It is working fine for logs that we see using "kubectl logs" or logs that come to stdout. However, I need to pick logs from a jenkins job (Console output of a jenkins job build). These logs are not going to std out of the node, and are stored at /var/jenkins_home/jobs/XXX/builds/<buildno> inside the container storage which is not directly accessible to fluentd for log collection.
I am open for any kind of solution to this problem. Please suggest.
Fluentd dont have any feature like this in case of kubernetes as kubernetes will not allow direct access to any third party plugin to read the data from container. For STDOUT log also first processed by kubernetes and kept at node level. After that you will be able to see.
As a workaround you can follow below link.
Kubernetes - How to read logs that are written to files in pods instead of stdout/stderr?
Long way:
Add hostpath directory volume to a jenkins deployment:
https://kubernetes.io/docs/concepts/storage/volumes/#hostpath
Run a separate FluentBit/Fluentd to collect logs from that directory.
Both of them support putting path in a dedicated field in a log or to a tag:
https://docs.fluentbit.io/manual/pipeline/inputs/tail
Use path/tag to parse-out job name and organize the destination storage accordingly. Or just leave it as is and filter on the view.
Short way:
Use jenkins kubernetes plugin to run each job as a separate pod:
https://plugins.jenkins.io/kubernetes/.
Then it will get collected and tagged by a daemonset separately.
Regarding Cloud Native Jenkins log management
Pipeline Log Storage API and reference implementations are available for preview, only Jenkins Pipeline job types are supported. Related JEP: JEP-210. Available plugins are AWS CloudWatch and Elasticsearch
Jenkins core APIs and reference implementations have not been merged/released yet, but prototypes are available for evaluation. Related JEPs: JEP-207, JEP-212. Available plugins are External Logging API and Elasticsearch

As i am trying to install Jenkins on cloud server and i installed that but after installation when it is asking for the /var/lib/jenkins/secrets/initialAdminPassword i am providing that also but after that i should get a plugin page but i am directly coming into Jenkins home page.
I have tried the installing jenkins again but still i am getting this below error.
Jenkins root URL is empty but is required for the proper operation of many Jenkins features like email notifications, PR status update, and environment variables such as BUILD_URL.
Please provide an accurate value in Jenkins configuration.
can any one tell me why this happening.enter image description here
I am facing some issues in fetching Jenkins build data into influxDB. Actually, the main requirement is to show Jenkins job build results on Grafana dashboard. So, I have created a Jenkins freestyle job and also installed influxDB plugin(1.17) and then I executed Windows batch command (as I am using a Windows 7 machine). it throws nullpointerexception. Please let me know what i need to do.
Images are given below.

I currently am using filebeat to ship my Jenkins build log from /var/log/jenkins.
I grok the build logs with Logstash so I can display the success/fail etc in Kibana and make some dashboard --> this is working well.
One thing I cannot seem to get is the total build times for the job as a whole.
I am using pipeline and multi pipeline build job types.
I can see the build stage time totals in the console logs but no matter the logging level I set globally for Jenkins, these do not display in the logs.
Has anyone managed to get this right?
Thanks
We have been using this Jenkins logstash-plugin https://wiki.jenkins.io/display/JENKINS/Logstash+Plugin
successfully to stash the data from Jenkins jobs to elasticsearch.
Supported indexers by this plugins are available in this link
https://wiki.jenkins.io/display/JENKINS/Logstash+Plugin#LogstashPlugin-IndexersCurrentlySupported
We are using the elasticsearch indexer which stashes the data directly to elasticsearch but if you want your data to go via logstash you can use Logstash indexer.
The payload format for the data is as below

Is there a way to configure the JaCoCo Jenkins Plugin coverage threshold through a shell script or API? For ex: I want to make an app to change code coverage threshold values for my Jenkins Jobs. How would I do it if I want my Jenkins instance abstracted?
Okay, turns out its a bit simple really. Plugin configurations are stored in an XML file. Global configurations in .jenkins root folder and job specific configurations in $HOME/.jenkins/jobs/{JOB_NAME}/config.xml.
Modify the config.xml file to store new configurations. This configuration file is exposed by each job at http://<SERVER>:<PORT>/jenkins/job/<JOB NAME>/config.xml. Since Jenkins loads this data at first load, you need to execute 'Reload Configuration From Disk' in Global configuration.
Since we're updating the XML from an API, you need to tell jenkins to reload configuration from an API as well. To do that, execute a shell to use jenkins_cli.jar's reload-configuration command.
Reference : Does anyone know how to reload hudson configuration without restarting?
