APM Server

The APM Server receives data from the Elastic APM agents and stores the data into Elasticsearch.

Read more about Elastic APM.

Please take questions or feedback to the Discuss forum for APM.

Getting Started

To get started with APM please see our Getting Started Guide.

APM Server Development

Requirements

• Golang 1.13.8

Install

• Fork the repo with the Github interface and clone it:

cd ${GOPATH}/src/github.com/elastic/
git clone [e-mail]:[USER]/apm-server.git

Note that it should be cloned from the fork (replace [USER] with your Github user), not from origin.

• Add the upstream remote: git remote add elastic [e-mail]:elastic/apm-server.git

Build

To build the binary for APM Server run the command below. This will generate a binary in the same directory with the name apm-server.

make

You also need to create all files needed by the APM Server by running the additional command below.

make update

Note that this requires to have virtualenv installed.

Run

To run APM Server with debugging output enabled, run:

./apm-server -c apm-server.yml -e -d "*"

Testing

For Testing check out the testing guide

Update

Each beat has a template for the mapping in elasticsearch and a documentation for the fields which is automatically generated based on fields.yml. To generate required configuration files and templates run:

make index-template update

Cleanup

To clean APM Server source code, run the following commands:

make fmt

To clean up the build directory and generated artifacts, run:

make clean

For further development, check out the beat developer guide.

Update Dependencies

The apm-server has two types of dependencies, the Golang packages managed with Govendor and a dependency to the Beats Framework.

Govendor

Checkout the govendor tool.

To update beats to the most recent version from your go path for example use: govendor fetch github.com/elastic/beats/.... Govendor will automatically pick the files needed.

Beats Framework Update

To update the beats framework run make update-beats. This will fetch the most recent version of beats from master and copy the files which are needed for the framework part to the _beats directory. These are files like libbeat config files and scripts which are used for testing or packaging.

It is recommended to keep the version of the beats framework and libbeat in sync. To make an update of both, run:

make update-beats

To update the dependency to a specific commit or branch run command as following:

BEATS_VERSION=f240148065af94d55c5149e444482b9635801f27 make update-beats

Go-elasticsearch client Update

It is important to keep the used go-elasticsearch client in sync with the according major version. We also recommend to use the latest available client for minor versions. Since APM Server does not yet support go modules, you can update the dependency using govendor, e.g. by running:

git clone --branch v7.4.1 https://github.com/elastic/go-elasticsearch.git $GOPATH/src/github.com/elastic/go-elasticsearch/v7
govendor add github.com/elastic/go-elasticsearch/v7/^
mv ./vendor/github.com/elastic/go-elasticsearch/v7/LICENSE ./vendor/github.com/elastic/go-elasticsearch/

Packaging

The beats framework provides tools to cross-compile and package apm-server for different platforms. This requires docker, mage, and vendoring as described above. To build all apm-server packages from source, run:

mage package

This will fetch and create all images required for the build process. The whole process can take several minutes. When complete, packages can be found in build/distributions/.

Building docker packages

To customize image configuration, see the docs.

To build docker images from source, run:

PLATFORMS=linux/amd64 mage -v package

When complete, docker images can be found through the local docker daemon and at build/distributions/apm-server-*-linux-amd64.docker.tar.gz.

When building images for testing pre-release versions, we recommend setting SNAPSHOT=true in the build environment, to clearly indicate the packages are not for a specific release.

Documentation

The Documentation for the APM Server can be found in the docs folder.
