Plugin Information

View Least Load on the plugin site for more information.

This plugin overrides the default Load Balancer behavior and assigns jobs to nodes with the least load

Overview

By default Jenkins tries to allocate a jobs to the last node is was executed on. This can result in nodes being left idle while other nodes are overloaded. This plugin overrides the default behavior and assigns jobs to nodes with the least load. The least load is defined as a node that is idle or the one with the most available executors. It is intended to provide the same functionality as the commercial plugin Even Scheduler Plugin

Configuration

The plugin requires no global configuration it will just replace the default load balancer at startup. Jobs can be configured to utilize the default Jenkins load balancer if required.

  1. Good idea for an extension - is there a way to take into account the actual load on the CPU on each machine as well though, in addition to what the other executors on each machine may be doing? In our environment, a jenkins slave may also have other processes running on it that are consuming the CPU, so it's important to be able to select a machine that is currently not under load.

    1. We also have the situation where slaves may be running processes not owned by Jenkins.  The ability to recognise actual cpu load would be really useful.

  2. when this plugin choose a idle slave,  whether it will check the slave in the building project's restriction or not?

    for example:

         the confirmation of projectA is restricted to host which label "java6",  when the least load plugin chooses a candidate slave ,does it check the candidate's label.
