HTTP Metrics

Collect and ship HTTP endpoint server metrics to Logstash and Elasticsearch.

Metricbeat is a lightweight shipper that helps you monitor your servers by collecting HTTP endpoint server metrics. Configure Metricbeat using the pre-defined examples below to collect and ship abitrary HTTP endpoint server metrics and statistics to Logstash or Elasticsearch.

Step 1 - Install Metricbeat

deb (Debian/Ubuntu/Mint)

curl -L -O https://artifacts.elastic.co/downloads/beats/metricbeat/metricbeat-oss-7.8.1-amd64.deb
sudo dpkg -i metricbeat-oss-7.8.1-amd64.deb

rpm (CentOS/RHEL/Fedora)

curl -L -O https://artifacts.elastic.co/downloads/beats/metricbeat/metricbeat-oss-7.8.1-x86_64.rpm
sudo rpm -vi metricbeat-oss-7.8.1-x86_64.rpm

macOS

curl -L -O https://artifacts.elastic.co/downloads/beats/metricbeat/metricbeat-oss-7.8.1-darwin-x86_64.tar.gz
tar xzvf metricbeat-oss-7.8.1-darwin-x86_64.tar.gz

Windows

Download the metricbeat Windows zip file from the official downloads page.
Extract the contents of the zip file into C:\Program Files.
Rename the metricbeat-<version>-windows directory to metricbeat.
Open a PowerShell prompt as an Administrator (right-click the PowerShell icon and select Run As Administrator). If you are running Windows XP, you may need to download and install PowerShell.
Run the following commands to install metricbeat as a Windows service:

cd 'C:\Program Files\metricbeat'
.\install-service-metricbeat.ps1

If script execution is disabled on your system, you need to set the execution policy for the current session to allow the script to run. For example: PowerShell.exe -ExecutionPolicy UnRestricted -File .\install-service-metricbeat.ps1.

My OS isn't here! Don't see your system? Check out the official downloads page for more options (including 32-bit versions).

Step 2 - Locate configuration file

deb/rpm /etc/metricbeat/metricbeat.yml
mac/win <EXTRACTED_ARCHIVE>/metricbeat.yml

Step 3 - Configure output

We'll be shipping to Logstash so that we have the option to run filters before the data is indexed.
Comment out the elasticsearch output block.

## Comment out elasticsearch output
#output.elasticsearch:
#  hosts: ["localhost:9200"]

Uncomment and change the logstash output to match below.

output.logstash:
    hosts: ["your-logstash-host:your-ssl-port"]
    loadbalance: true
    ssl.enabled: true

Step 4 - Validate configuration

Let's check the configuration file is syntactically correct by running metricbeat directly inside the terminal. If the file is invalid, metricbeat will print an error loading config file error message with details on how to correct the problem.

deb/rpm

sudo metricbeat -e -c /etc/metricbeat/metricbeat.yml

macOS

cd <EXTRACTED_ARCHIVE>
./metricbeat -e -c metricbeat.yml

Windows

cd <EXTRACTED_ARCHIVE>
.\metricbeat.exe -e -c metricbeat.yml

Step 5 - Enable module

There are several built in metricbeat modules you can use. To enable the HTTP module run.

deb/rpm

metricbeat modules list
metricbeat modules enable http

macOS

./metricbeat modules list
./metricbeat modules enable http

Windows

PS > .\metricbeat.exe modules enable http

Step 6 - Configure module

Each module has its own configuration file where different metricsets can be enabled / disabled. Locate the configuration file for the HTTP module.

deb/rpm /etc/metricbeat/modules.d/http.yml

mac/win ~/<EXTRACTED_ARCHIVE>/modules.d/http.yml

By default the HTTP json and server metricsets are disabled. To enable or disable a metric simply comment or uncomment the line out.

- module: http
  #metricsets:
  #  - json
  period: 10s
  hosts: ["localhost:80"]
  namespace: "json_namespace"
  path: "/"
  #body: ""
  #method: "GET"
  #username: "user"
  #password: "secret"
  #request.enabled: false
  #response.enabled: false
  #json.is_array: false
  #dedot.enabled: false

- module: http
  #metricsets:
  #  - server
  host: "localhost"
  port: "8080"
  enabled: false
  #paths:
  #  - path: "/foo"
  #    namespace: "foo"
  #    fields: # added to the the response in root. overwrites existing fields
  #      key: "value"

Step 7 - Start Metricbeat

Ok, time to start gathering metrics!

deb/rpm

sudo systemctl enable metricbeat
sudo systemctl start metricbeat

macOS

./metricbeat

Windows

PS C:\Program Files\Metricbeat> Start-Service metricbeat
