Default Parameters for DockContImgTest

This test reports the total number of images that are available on the Docker host/server. In addition, this test helps administrators to compare the numerical statistics of the images that are mapped to the containers and those that are not mapped to any container. Likewise, administrators can also be able to figure out the disk space utilization of images that are mapped to the containers and the disk space utilization of the images that are not mapped to the containers. Using this test, administrators can figure out the images that are sparsely utilized, the images that are consuming too much of disk space etc and take remedial actions to restrict the disk space utilization of the images.

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

• 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.

• 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.
