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/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 tometricbeat
. - 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
PowerShell.exe -ExecutionPolicy UnRestricted -File .\install-service-metricbeat.ps1
.
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 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
