Find and Stop Idle Sessions

You can identify idle NICE DCV sessions using the dcv describe-sessions CLI command with the -j command option. Specifying the -j option configures the command to return the output in JSON format, which provides additional details about the session.

For example, the following command returns information about a session named my-session.

$ dcv describe-session my-session -j

Output:

{
    "id" : "my-session",
    "owner" : "dcvuser",
    "x11-display" : ":1",
    "x11-authority" : "/run/user/1009/dcv/test3.xauth",
    "num-of-connections" : 1,
    "creation-time" : "2019-05-13T13:21:19.262883Z",
    "last-disconnection-time" : "2019-05-14T12:32:14.357567Z",
    "licensing-mode" : "DEMO",
    "licenses" : [
        {
            "product" : "dcv",
            "status" : "LICENSED",
            "check-timestamp" : "2019-05-14T12:35:40Z",
            "expiration-date" : "2019-05-29T00:00:00Z"
        },
        {
            "product" : "dcv-gl",
            "status" : "LICENSED",
            "check-timestamp" : "2019-05-14T12:35:40Z",
            "expiration-date" : "2019-05-29T00:00:00Z"
        }
    ]
}

In the command output, the num-of-connections parameter indicates the number of active client connections. A value of 0 indicates that there are no active client connections, and that the session is currently idle. You can also use the last-disconnection-time parameter to determine when the session last had an active client connection.

You can create a script or cron job that uses this information to identify idle sessions. Then you can stop using them by using the dcv close-session command.
