Performing a Health Check of Infrastructure Components

 

After you install or upgrade CSO, you can run the components_health.sh script to perform a health check of all infrastructure components. This script detects whether any infrastructure component has failed and displays the health status of the following infrastructure components:

  • Cassandra

  • Elasticsearch

  • Etcd

  • MariaDB

  • RabbitMQ

  • ZooKeeper

  • Redis

  • ArangoDb

  • SimCluster

  • ELK Logstash

  • ELK Kibana

  • Contrail Analytics

  • Keystone

  • Swift

  • Kubernetes

To check the status of infrastructure components:

  1. Login to the installer VM as root.
  2. Navigate to the CSO directory in the installer VM.

    For example:

    root@host:~/# cd Contrail_Service_Orchestration_4.0
  3. Run the components_health.sh script.

    To check the status of infrastructure components of the central environment, run the following command:

    root@host:~/Contrail_Service_Orchestration_4.0#./components_health.sh central

    To check health component of the regional environment, run the following command:

    root@host:~/Contrail_Service_Orchestration_4.0#./components_health.sh regional

    To check health component of central and regional environments, run the following command:

    root@host:~/Contrail_Service_Orchestration_4.0# ./components_health.sh

    After a couple of minutes, the status of each infrastructure component for central and regional environments are displayed.

    For example:
