System Metrics for CentOS

To get started first follow the steps below:

• Install metricbeat
• Root access
• Verify the required port is open

Older versions can be found here metricbeat 7, metricbeat 6, metricbeat 5

The configuration file below is pre-configured to send data to your Logit.io Stack via Logstash.

Copy the configuration file below and overwrite the contents of metricbeat.yml.

###################### Logit.io Metricbeat Configuration #######################
# =========================== Modules configuration ============================

metricbeat.config.modules:
  # Glob pattern for configuration loading
  path: ${path.config}/modules.d/*.yml

  # Set to true to enable config reloading
  reload.enabled: false

  # Period on which files under path should be checked for changes
  #reload.period: 10s
# ======================= Elasticsearch template setting =======================
setup.template.settings:
  index.number_of_shards: 1
  index.codec: best_compression
  #_source.enabled: false

# ================================== Outputs ===================================
# ------------------------------ Logstash Output -------------------------------
<div class="sw-warning">

    <div>
       <b>No input available! </b> Your stack is missing the required input for this data source <a href="#" onclick="Intercom('showNewMessage')" class="btn btn-info btn-sm">Talk to support to add the input</a>

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

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

Start or restart metricbeat to apply the configuration changes.

Data should now have been sent to your Stack.

If you don't see logs take a look at How to diagnose no data in Stack below for how to diagnose common issues.

If you don't see data appearing in your Stack after following the steps, visit the Help Centre guide for steps to diagnose no data appearing in your Stack or Chat to support now.

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

CentOS (short for Community Enterprise Operating System) is a popular and respected open-source Linux distribution known for its stability, reliability, and robust performance.

It serves as a free and community-supported alternative to its commercial counterpart, Red Hat Enterprise Linux. CentOS is widely utilized in enterprise environments, data centres, and web hosting services due to its strong focus on delivering a secure and consistent platform for various computing needs.

One of CentOS's key strengths is its long-term support (LTS) approach, which ensures that security patches and updates are provided for an extended period. This stability makes it an ideal choice for mission-critical applications and server infrastructure.

Additionally, CentOS benefits from a vast and active community of developers and users, which contributes to its continuous improvement and adaptability to evolving technologies.

When it comes to collecting and shipping metrics from a CentOS-based environment, numerous tools and methodologies can be employed. This includes monitoring system performance, network activity, application behaviour, and more.

By efficiently gathering and transmitting this data, organizations can gain valuable insights into the health and performance of their CentOS systems, enabling them to make informed decisions, troubleshoot issues, and optimize their infrastructure.
