Run a specified command and output the results to a file.

Run Collector

The run collector runs the specified command and includes the results in the collected output.


In addition to the shared collector properties, the run collector accepts the following parameters:

command (Required)

The command to execute on the host. The command gets executed directly and is not processed by a shell. You can specify a shell if you want to use constructs like pipes, redirection, loops, etc. Note that if you want to run your command in a shell, then your command should be a single string argument passed to something like sh -c. See the run-with-shell example.

args (Required)

The arguments to pass to the specified command.

Example Collector Definition

apiVersion: troubleshoot.sh/v1beta2
kind: SupportBundle
  name: run
    - run:
        collectorName: "ping-google"
        command: "ping"
        args: ["-c", "5", "google.com"]
    - run:
        collectorName: "run-with-shell"
        command: "sh"
        args: ["-c", "du -sh | sort -rh | head -5"]

Included Resources

The results of the run collector are stored in the host-collectors/run-host directory of the support bundle.


If the collectorName field is unset, it will be named run-host.json.
