Httpbeat

I'm happy to announce that Httpbeat will become a core feature of the Beats framework 6.0 with the introduction of the Http module of Metricbeat.

I would like to give special thanks to Nicolas Ruflin for his support during the migration of the Httpbeat into the new Http module.

I will continue the support for Httpbeat for Beats 5.x, but all users of Beats 6.0 and newer versions are encouraged to migrate to the Http module of Metricbeat.

Welcome to Httpbeat.

Httpbeat is a Beat used to call HTTP endpoints. Multiple endpoints can be configured which are polled in a regular interval and the result is shipped to the configured output channel.

Httpbeat is inspired by the Logstash http_poller input filter but doesn't require that the endpoint is reachable by Logstash as Httpbeat pushes the data to Logstash or Elasticsearch. This is often necessary in security restricted network setups, where Logstash is not able to reach all servers. Instead the server to be monitored itself has Httpbeat installed and can send the data or a collector server has Httpbeat installed which is deployed in the secured network environment and can reach all servers to be monitored.

Example use cases are:

• Monitor Apache Stats
• Monitor Java application with Jolokia
• Monitor Spring Boot Actuators
• Monitor Docker Remote API

Ensure that this folder is at the following location: ${GOPATH}/src/github.com/christiangalsterer

Installation

Download

Pre-compiled binaries for different operating systems are available for download.

Installation

Install the package for your operation system by running the respective package manager or unzipping the package.

Configuration

Adjust the httpbeat.yml configuration file to your needs. You may take httpbeat.full.yml as an example containing all possible configuration values.

Running

In order to start Httpbeat please use the respective startup script, e.g. /usr/bin/httpbeat.sh.

Starting Httbeat as Service

Where supported Httpbeat can be started also using the respetive service scripts, e.g. etc/init.d/httpbeat.

Building and Releasing Httpbeat

Requirements

• Golang 1.9
• Glide >= 0.13.0

Build

To build the binary for httpbeat run the command below. This will generate a binary in the same directory with the name httpbeat.

make clean && make

Run

To run httpbeat with debugging output enabled, run:

./httpbeat -c httpbeat.yml -e -d "*"

To run httpbeat in normal mode, run:

./httpbeat -c httpbeat.yml

Test

To test httpbeat, run the following command:

make testsuite

alternatively:

make unit-tests
make system-tests
make integration-tests
make coverage-report

The test coverage is reported in the folder ./build/coverage/

Update

Each beat has a template for the mapping in elasticsearch and a documentation for the fields which is automatically generated based on etc/fields.yml. To generate etc/httpbeat.template.json and etc/httpbeat.asciidoc

make update

Cleanup

To clean httpbeat source code, run the following commands:

make check
make simplify

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

make clean

Clone

To clone httpbeat from the git repository, run the following commands:

mkdir -p ${GOPATH}/github.com/christiangalsterer
cd ${GOPATH}/github.com/christiangalsterer
git clone https://github.com/christiangalsterer/httpbeat

For further development, check out the beat developer guide.

Packaging

The beat frameworks provides tools to crosscompile and package your beat for different platforms. This requires docker and vendoring as described above. To build packages of your beat, run the following command:

make package

This will fetch and create all images required for the build process. The hole process to finish can take several minutes.
