Monitoring host resources

To monitor host resources, you must add the monitoring sources to the Resource Monitoring service, enter connection settings and select performance counters that are used to capture the performance statistics.

Before you begin

You must be logged in HCL OneTest™ Server and be the owner of an existing new project.

If you monitor a remote host, it must be connected with the computer that you use to access Resource Monitoring service. See Connecting agents to the Resource Monitoring service.

About this task

This task applies to NGINX and NGINX Plus, Apache httpd server, Java Virtual Machine, Windows Performance host, Linux Performance host, and Docker host sources.

Procedure

  1. In the Resource Monitoring page, click Add a source, for example: Add an NGINX server.
  2. In the New server dialog box, fill in the following connection settings:
    1. In Target host, enter the IP address or host name and port number of the host where the server to monitor is installed.
    2. In Server edition, select the appropriate server from the drop-down list.
    3. In Path to the status page of the server, enter the name of the page to view the status of the server.

      If you select NGINX Plus (with API version 3) as a source, you must specify the name of the path to view the API root of the NGINX Plus server.

    4. In Security, select the following options:
      Secured with TLS/SSL
      If the application server is secured with TLS/SSL.
      Trust self-signed certificate
      To accept the server certificate.
      Do not verify host name
      To ignore verification of the host name in the certificate.
      Require credentials
      If the server requires log-in credentials, enter a User name and Password.
      Add a source
      For remote hosts that are already connected to HCL OneTest™ Server through an agent, you have only the Access target from field enabled.
    5. Click Add.
  3. Select and save the resource counters to monitor. You can select them from the list where they follow the server logical organization.Choose Data Counters pageFor a faster selection, select the counters from the built-in sets drop-down list where they are organized by theme and save your selection. Choose data counters with the filters
    Note:
    For Docker host, you can select different sets of counters.
    • The first level of counters: Generic counters that are related to a Docker Image and all its running Docker Containers (in an exit, running or paused, created, restarted, removing, dead or transitive state).
    • The second level of counters: Specific counters that are related to the existing Docker Containers.

    When the selected counters are saved, two tables are displayed in the resource monitoring main page. They contain the total number of sources you have added and the number of sources ordered by type.
