Default Parameters for DockContblkioTest

For each IO policy that is implemented in the Docker, this test monitors the rate of read and write data traffic and also reports synchoronous and asynchoronous IO operations.

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

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

  • The Docker server denies a ‘normal’ Docker user access to the statistics pertaining to the Docker containers and its utilization. This implies that the Docker user should be within the Docker group in order to extract statistics from the Docker server. In cases where the Docker user is not within the Docker group, administrators may want to set the USESUDO flag to Yes. Set this flag to No if the Docker user is indeed part of a Docker group.

  • Specify the credentials of a user who has the right to execute API commands on the Docker server and pull out metrics, in the DOCKER USER and DOCKER PASS text boxes. The specified user should have access to the Docker group.

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

  • When installing Docker, the daemon is configured to listen on a specific web port such that the REST API can be accessed via the specified web port without any additional configuration. You can specify the configured web port at which the daemon in your environment listens so that the eG agent communicates with that port against the WEBPORT parameter.

  • 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.
