System Metrics for Red Hat (RHEL)

Collect and ship Red Hat Enterprise Linux (RHEL) operating system and service metrics to Logstash and Elasticsearch.

Metricbeat is a lightweight shipper that helps you monitor your servers by collecting metrics from the operating system and from services running on the Redhat server. Configure Metricbeat using the pre-defined examples below to collect and ship Red Hat Enterprise Linux (RHEL) operating system, service metrics and statistics to Logstash or Elasticsearch.

Step 1 - Install Metricbeat

deb (Debian/Ubuntu/Mint)

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

rpm (CentOS/RHEL/Fedora)

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

macOS

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

Windows

Download the Windows zip file from the official downloads page.
Extract the contents of the zip file into C:\Program Files.
Rename the -<version>-windows directory to ``.
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 as a Windows service:

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

/etc/metricbeat/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"]

No input available! Your stack is missing the required input for this data source Talk to support to add the input

Step 4 - Validate configuration

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

deb/rpm

sudo  -e -c /etc//.yml

macOS

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

Windows

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

Step 5 - Enable module

There are several built in metricbeat modules you can use. To enable the system module, run the following:

metricbeat modules list
metricbeat modules enable system

Step 6 - Configure module

Each module has its own configuration file where different metricsets can be enabled / disabled. Locate the configuration file for the system module. /etc/metricbeat/modules.d/system.yml

By default the following metrics are enabled. To enable or disable a metric simply comment or uncomment the line out.

- module: system
  period: 10s
  metricsets:
    - cpu
    - load
    - memory
    - network
    - process
    - process_summary
    - socket_summary
    #- core
    #- diskio
    #- socket

Step 7 - Start Metricbeat

Ok, time to start ingesting data!

sudo systemctl enable metricbeat
sudo systemctl start metricbeat

Step 8 - System module dashboard

The System module comes with a predefined Kibana dashboard. To view your dashboards for any of your Logit.io stacks, launch Kibana and choose Dashboards.
