es-logger 2.33

Framework for Creating Logstash events from Jenkins Jobs

ES-Logger

The es-logger project intends to build a pluggable data processor that will take data from Jenkins builds and push that data into Elasticsearch via Logstash.

Installation and Running

Install the framework using:

python ./setup.py install

Install from source for developing using:

python ./setup.py develop

Install from pypi repository with:

pip install es-logger

After that, set environment variables needed, and just execute es-logger!

Jenkins Connection

• JENKINS_URL - Used to prefix the location to gather Jenkins data from using the python-jenkins library
• JENKINS_USER - Username to access Jenkins
• JENKINS_PASSWORD - Password to access Jenkins. Can also be an API key

Job Information

• ES_JOB_NAME - The full job name with all paths, added to the JENKINS_URL
• ES_BUILD_NUMBER - The build number to collect data for

Plugins

• PROCESS_CONSOLE_LOGS - Console log processor plugins to run, space separated list
• GATHER_BUILD_DATA - Build data gatherer plugins to run, space separated list
• GENERATE_EVENTS - Event generator plugins to run, space separated list

Logstash Target

• LOGSTASH_SERVER - HTTP server configured to receive json messages, as per the sample configuration
• LS_USER - User to connect to Logstash with
• LS_PASSWORD - Password to connect to Logstash with

Plugins

The plugin infrastructure is provided by the stevedore library.

There are following types of plugin supported:

Console Log Processors

These plugins will have a process function called that is passed the full console log of the job. It can perform any actions desirable, and shall return data, which will be added to the es_info['console_log_plugins'][plugin_name] structure that is pushed to logstash. A list or a dict is preferred as a return type.

Build Data Gatherers

These plugins will have a gather function that is passed the EsCollector object. This should provide any data needed for the plugin to gather any additional data that should be added to the es_info. This could include test results from an external system not available to Jenkins, parsed logs from an external piece of hardware, etc.

The return should be a dictionary, which will be added to the es_info['build_data'][plugin_name] structure that is pushed to logstash.

Event Generators

An event generator is intended to process the Jenkins information and generate a number of events based off that data. This allows for the creation of unique events per-host or per-test if the Jenkins job operates on multiple resources. The structures returned are expected to be very small, so surfacing data points to form the basis of visualisations. A small number of default fields will be added by the main program to identify the origination of the data, and the event data will become contained in a top-level key named after the plugin.

The return from the generator should be a list of events that will be posted to logstash
