System Metrics for Ubuntu
Collect and ship Ubuntu 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 Ubuntu server. Configure Metricbeat using the pre-defined examples below to collect and ship Ubuntu operating system, service metrics and statistics to Logstash or Elasticsearch.
Step 1 - Install Metricbeat
First we need to install Metricbeat.
sudo apt-get install apt-transport-https
wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
echo "deb https://artifacts.elastic.co/packages/oss-6.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-6.x.list
sudo apt-get update && sudo apt-get install metricbeat
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"]
Uncomment and change the logstash output to match below.
output.logstash:
hosts: ["your-logstash-host:your-port"]
loadbalance: true
ssl.enabled: true
Step 4 - 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 5 - 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 6 - Start Metricbeat
Ok, time to start ingesting data!
sudo systemctl enable metricbeat
sudo systemctl start metricbeat
Step 7 - System module dashboard
The System module comes with a predefined Kibana dashboard. To view your dashboards for any of your Logit stacks, launch Kibana and choose Dashboards.
