CA-APM2.1.1Minimum Jenkins requirement: 2.60.1ID: ca-apm
CA APM PluginAllows users to collect CA APM performance data and publish it in Jenkins and allows the users to publish build number, status etc into CA-APM APM Team Center(ATC)
For ca-apm 1.x please refer to CA APM Plugin 1.x
CA APM Plugin 2.x and later
Jenkins is a tool to automate continuous delivery pipelines. A most common use of Jenkins is to run tests against the new builds of an application. The CA APM Jenkins plug-in extension automates comparing the performance of builds. The plug-in provides abstraction to run the plug-in after any LoadGenerator, define multiple comparison strategies and define multiple output handlers.
- LoadGenerator :You can use any load generators example - Jmeter and CA Balzemeter
- Comparison Strategies: CA Jenkins plugin supports the following comparison strategies:
- Mean Latency: Compares the average value of a metric of a transaction with its corresponding value of benchmark build.
- Static Threshold: Compares the value of the metric with the corresponding threshold value defined in the configuration.
- Output Handlers: Email HTML Report, JSON, and Chart Output, Histogram Chart Output
- Ability to fetch multiple metrics using regex as KPI for tracking
- Ability to configure multiple fail conditions
- Metric A less than or greater than a constant value OR
- Metric A in comparison to Metric B
- Ability to send notification via Email (if smtp server is configured)
- Ability to view KPI's per build or cross build dashboard in Jenkins
- Ability to decorate APM Team Center 10.1 nodes using custom attributes like build status, number and date
- Ability to just notify via email: If "justEmail" is checked the build will NOT be marked as fail even if the conditions are met but only a notification will be sent
- Ability Jump to Webview in context (for both metric and time range) from build or x-build dashboard
Note: 2.0 is not APM 11.1 compatible.
Jenkins version 2.60.1 or newer
CA APM Jenkins plug-in Packaging
The CA APM Jenkins plug-in package contains the following folder and files:
ca-apm-jenkins.hpi (HPI file)
- javadoc directory - Contains java documentation about comparison-strategy, output-handler, and available helper utilities
Install the Jenkins plug-in
This section describes the steps to install the plug-in. You can install the Jenkins plug-in from the Jenkin's Manage Plug-ins page.
Follow these steps:
- Select Jenkins, Manage Jenkins, Manage plugins.
The Manage Plug-in page opens.
- Select the Advanced tab.
The HTTP Proxy Configuration page opens.
Browse and upload the performance-comparator-jenkins.hpi file available in the Repo directory.
Wait for the installation to complete.
Note: Ensure that no jobs are running
- Restart the Jenkins when installation is complete.
Using the Jenkins Pipeline Syntax to Run the CA APM Jenkins plug-in
Jenkins job can be configured with any load generator to generate the load on the application, as below, before running the ca-apm plugin.
To use BlazeMeter in pipeline syntax you need to have BlazeMeter Plugin
Please refer the below sample pipeline Blazemeter script from APM 10.x.
Please refer the below Sample pipeline Blazemeter script from DX APM 11.1 onwards and DX APM SaaS
map = [jenkinsPluginName: "CAAPM"];
Sample pipeline scripts with JMeter for APM 10.x
Refer the below script from DX APM 11.1 onwards and DX APM SaaS
Note: Each Jenkins job will be binded with the parameters loadGeneratorName, loadGeneratorStartTime, loadGeneratorEndTime of the Load Generator and the same parameters will be passed to the plugin.
Follow these steps:
- Add the predefined stage in your existing pipeline job.
- Run the Jenkins job.
Important: The Jenkins plug-in and the properties files must be in the same machine.
Configure properties in performance-comparator.properties file.
Download the performance-comparator.properties file from http://repo.jenkins-ci.org/releases/org/jenkins-ci/plugins/ca-apm/ca-apm-dist/<version>/ca-apm-dist-<version>.zip
Please refer the Configure the CA APM Jenkins Plugin Properties
Default Comparison Strategies and Output Handler Available with the plug-in
The plug-in has the following built-in Comparison Strategies and Output Handlers.
List of Available Comparison-Strategies
By default the following strategies are executed:
If you do not want to execute the default strategy, remove the corresponding strategy name from
comparisonstrategies.list property value list.
For example, for meanLatencyStrategy, it can be any RegEx like *Frontend.*Health: Average Response Time \\(ms\\). Do not remove Health: Average Response Time \\(ms\\), else it looses its logical meaning.
By default, the following comparison-strategies are available with the plug-in:
Mean Latency Comparison Strategy
The strategy compares the average value of the metric between current build and benchmark build with threshold of five percentage. You can set a custom value for the <metricName>
.threshold property. The following code shows the sample configuration:
Static Threshold Strategy
The strategy compares your Concurrent Invocation metric of transactions of the current build with the given threshold value (2).
List of Available Output-Handlers
The plug-in provides the following default output handlers that are mapped to all the following default comparison-strategies in the outputhandlers property. You can remove any or all of the output handlers. The output-handlers should be declared with the below property as below:
Plain Text Email Report Output Handler
The handler generates a plain text email comparison report. The report contains the metrics for all the strategies that are mapped that are in the properties file.
JSON File Output Handler
The handler generates a JSON report of the average value of the metrics comparison between current build and benchmark build as a percentage.
Chart Output Handler
The handler generates a Chart Output of comparison of performance metrics between benchmark build and current build.
The output is stored in
<current_build>/workspace/chartOutput folder. The output html files are in the
chartOutput/output folder. The folder contains one file for each comparison-strategy. For Example, If one comparison strategy has six metric paths that are identified, then the output file contains six charts.
Histogram Output Handler
The handler generates build to build comparison in histogram style, with the average value of each metric for each build, default it render for 10 builds.
Comparison Strategy to Output-Handler Mapping
The mapping lets you receive the output from only those
comparison-strategies which are mapped to output-handler using the
outputHandlers property. The communication between a comparison-strategy and output-handler happens using the Data Structure T within
StrategyResult Entity.Map the comparison-strategy and output-handler using the same data format. If the mapping is incorrect, it is not processed by Output-Handler and plug-in raises a warning.
The default implementation of T is DefaultStrategyResult provided with the plug-in. All the default strategies and output-handlers communicate using the
DX APM SaaS Integration
