Default Parameters for DockContPerfTest

This test monitors each container available in the Docker and reports the CPU utilization, I/O processing, memory related statistics such as memory utilization, paging in/paging outs, errors that were detected etc.

This page depicts the default parameters that need to be configured for the DockContPerfTest.

  • The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

  • By default, the USESUDO flag is set to Yes indicating either of the following:

    • The eG agent is using the sudo commands to collect the required metrics from the target docker server if monitored in an agent based manner or

    • The target docker server is monitored in an agentless manner and the eG agent install user is within a docker group.

    If the target docker server is monitored in an agentless manner and the user privileges are altered in the /etc/sudoers file, then, set this flag to No.

  • Specify the credentials of the user who is authorized to execute the docker commands on the target server in the DOCKER USER and DOCKER PASSWORD text boxes.

  • Confirm the DOCKER PASSWORD by retyping it in the CONFIRM PASSWORD text box.

  • By default, the Docker server listens on 2375. This implies that while monitoring a Docker server via an SSL-enabled environment, the eG agent, by default, connects to port 2375 of the Docker server to pull out metrics. In some environments however, this default port may not apply. In such a case, against the WEBPORT parameter, you can specify the exact port at which the Docker server in your environment listens so that the eG agent communicates with that port.

  • Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz” and $port will be changed to “80” when configuring a test.
