Default Parameters for DockContainerStTest

This test monitors the containers available in the Docker server and reports the numerical statistics of the total containers, the containers in Running state, the containers that were added, the containers that were removed etc. In addition, this test reports the containers that are not running for a time duration above the specified limit and the containers that are utilizing disk space above the specified limit. By analyzing this, administrators can figure out the overall performance of the Docker server and identify bottlenecks if any.

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

  • 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.

  • By default, the disk space utilized by each container may vary according to the size of the container. Sometimes, the containers may be over-utilizing the disk space which when left unnoticed may hamper the creation of new containers. To figure out such containers, you can specify a disk space limit beyond which the containers can be termed as large sized container. For example, if you wish to monitor the number of containers that are utilizing disk space above 50 MB, then specify 50 against the SIZE LIMIT IN MB text box.

  • For this test to report the numerical statistics of the containers that were not started/running, set a valid value against the TIME LIMIT IN WEEKS parameter. For example, if you wish to report the containers that were not started for more than 3 weeks, then set 3 against this text box.

  • By default, SHOW TOTAL CONTAINERS IN DD flag is set to Yes, indicating that this test will report detailed diagnostics for the Total Containers measure. You can disable the detailed diagnosis capability of the Total Containers measure by setting this flag to No.

  • By default, SHOW STOPPED CONTAINERS IN DD flag is set to Yes, indicating that this test will report detailed diagnostics for the Stopped Containers. You can disable the detailed diagnosis capability of the Stopped Containers measure by setting this flag to No.

  • The DD FREQUENCY refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD FREQUENCY.

  • 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.
