I have multiple installation of Jenkins servers. Is there a way to monitor all the jobs run from one Jenkins server?There is a option for master/slave in Jenkins. But apart from master/slave , is there a possibilty to achieve this?
The Scenario is each Devlopment team has local jenkins. We need to integrate the local jenkins to centralized jenkins. So the local build and deployment can happen in local Jenkins servers, For production deployment they can use Centralized Jenkins server.How to monitor the development Jenkins server.
Thanks

how can we tell Jenkins to download and run JMeter tests on a remote system rather than from the Jenkins server itself?
My requirement is to create a job in Jenkins to download the latest code from a repo to another system where JMeter is installed and run the JMeter tests on that remote system rather than from Jenkins server itself? I can trigger the tests from Jenkins server itself but unable to connect to remote server and download/trigger the server.
You need to get familiarized with the concept of Jenkins Distributed Builds, it's enough to start Jenkins agent proces on the "remote system" and bind your job to execute on that agent instead of Jenkins master.
With regards to tracking changes in the remote repo check out Generic Webhook Trigger and How to Integrate Your GitHub Repository to Your Jenkins Project articles
I would like to set up jenkins server that would run test scripts based on successful build deployments on other Jenkins servers. for example, if the QA jenkins server is named JQA1OnMachine1 and i have three others that are named
J2OnMachine2, J3OnMachine3, J4OnMachine4 (different jenkins server on different boxes) can the JQA1OnMachine1 (QA jenkis) poll the others at regular interval to see if a build was deployed successfully? if so can anyone tell me how?
Jenkins master slave along with Jenkins Pipeline Plugin would be one of the better ways to implement this however, since you don't want to use that approach you can explore PSTools to remotely capture processes or files on different server.
Your builds may update a file on the build server post completion of the build and your QA machine can run script with PSTools to monitor and trigger the QA testing based on the file content
I'm new to Jenkins, and I like to know if it is possible to have one Jenkins server to deploy / update code on multiple web servers.
Currently, I have two web servers, which are using python Fabric for deployment.
Any good tutorials, will be greatly welcomed.
One solution could be to declare your web servers as slave nodes.
First thing, give jenkins credentials to your servers (login/password or ssh login+private key or certificate. This can be configured in the "Manage credentials" menu
Then configure the slave nodes. Read the doc
Then, create a multi-configuration job. First you have to install the matrix-project plugin. This will allow you to send the same deployment intructions to both your servers at once
Since you are already using Fabic for deployment, I would suggest installing Fabric on the Jenkins master and have Jenkins kick off the Fabric commands to deploy to the remote servers. You could set up the hostnames or IPs of the remote servers as parameters to the build and just have shell commands that iterate over them and run the Fabric commands. You can take this a step further and have the same job deploy to dev/test/prod just by using a different set of hosts.
I would not make the webservers slave nodes. Reserve slave nodes for build jobs. For example, if you need to build a windows application, you will need a windows Jenkins slave. IF you have a problem with installing Fabric on your Jenkins master, you could create a slave node that is responsible for running Fabric deploys and force anything that runs a fabric command to use that slave. I feel like this is overly complex but if you have a ton of builds on your master, you might want to go this route.
We have a Jenkins system to automate build from Github, now we are implementing a Saltstack system. So I need to integrate my Jenkins with Salt-master so that it passes all the new builds to the master which then sends it across the salt-clients(minions).
The saltstack setup is in AWS cloud and and the Jenkins machine is outside the cloud in a local setup.
You could enable the salt-api and using the following plugin: https://wiki.jenkins-ci.org/display/JENKINS/saltstack-plugin then all of your jenkins builds can execute states / orchestrations etc. to any minions on a per job basis.
Another way of doing this is to have a minion running on the salt-master and install the jenkins slave on the same box. Then restrict the jenkins jobs to that jenkins slave and execute the commands as if you were at the command line. NOTE: this option requires a bit more configuration.
I've been reading about Jenkins master/slave configurations but I still have some questions:
Is it so that the slave Jenkins is not actually installed and started up the way master Jenkins is? I assumed I would install one master Jenkins and another slave Jenkins in the same way, and then master Jenkins would control the slave e.g. through SSH? So I cannot view the slave Jenkins through a GUI?
The reason why I have thought about adding a slave Jenkins on another VM is because the VM contains our application servers (many test environments). Deploying and starting/stopping application servers from master Jenkins is a pain because master Jenkins and application servers are on different machines. Therefore, if I would add a slave Jenkins to the machine where our application servers are, these would actually be deployed and started/stopped locally (by slave Jenkins). I wonder if I have missed something, of if my presumptions are still valid.
In a standard Jenkins master/slave setup, Jenkins is only installed on the master. That is where you see the user interface and start/configure build jobs.
The slaves execute the jobs. There is no Jenkins installation here other than a small Java app to have Jenkins communicate to/from the slave. Jenkins talks to these slaves through the slave.jar app over e.g. SSH via the SSH Slaves Plugin and can monitor if the slave is running, etc.
So in your case, you can start jobs from the master that will execute on the application servers.
The master/slave setup also allows you to host all whole bunch of different slaves, with different OSes, different hardware, etc. You can communicate job results (artifacts) from one slave to another via the Copy Artifacts Plugin.
There are also ways to duplicate the actual Jenkins master with load balancing in a heavy use scenario. That is not what you seem to be looking for.
