Using the Runtime Fabric Command Line Tool

Install and use the rtfctl command line tool to locally manage Runtime Fabrics. The rtfctl tool supports the following actions:

Get the status of a Runtime Fabric.
Perform a heap dump or a thread dump of a running application.
Display memory usage of a running application.
Manage proxy settings.
Manage secure properties.
Manage a Mule license.
Manage the alert sender email address.

If you are using the default namespace (rtf), you do not need to specify the additional flag --namespace <rtf_namespace>. Note that this flag is introduced only as of rtfctl version 0.4.1.

Install rtfctl

The tasks in the section must be performed by an IT administrator.

If you’re using Runtime Fabric for AKS and have the AKS-managed Azure AD integration enabled, the following command returns the credentials needed to run rtfctl commands:

az aks get-credentials --name <NAME> --resource-group <RESOURCE_GROUP> --admin

Download the rtfctl command-line tool:

rtfctl is supported on Windows, MacOS (Darwin), and Linux. Choose the appropriate method:

Windows

curl -L https://anypoint.mulesoft.com/runtimefabric/api/download/rtfctl-windows/latest -o rtfctl.exe

MacOS (Darwin)

curl -L https://anypoint.mulesoft.com/runtimefabric/api/download/rtfctl-darwin/latest -o rtfctl

Linux

curl -L https://anypoint.mulesoft.com/runtimefabric/api/download/rtfctl/latest -o rtfctl

Change file permissions for the rtfctl command-line tool:
```
chmod +x rtfctl
```

Running Commands

The rtfctl command line tool consumes kubeconfig files as described in Organizing Cluster Access Using kubeconfig Files. Use this method to configure which cluster you want to manage. Confirm that the rtfctl binary is present in the current working directory and in the user $PATH.

Run rtfctl commands as a privileged user.
To list all supported commands, run rtfctl -h.
For more information about a specific command, run rtfctl <command> -h.

Checking for Proxy Settings

When you run commands, rtfctl checks for any proxy settings in your environment. The tool looks for a NO_PROXY key (in upper case) and will accept a no_proxy key (in lower case) if NO_PROXY is not used. If both keys are present, rtfctl uses NO_PROXY. The rtfctl tool sets the key in your local Kubernetes context to honor your proxy settings.

Version:
Organization ID:   d30f74c0-XXXX

  hello-world-77f5897949-z54gb   Pending

Understanding rtfctl Output

The rtfctl command line tool commonly calls other applications and system tools, and the output of those calls is sent to standard output and standard error output. This output is written in the context of each operation performed.

The rtfctl command line tool includes a last output line on the most verbose commands to make it clear whether the operation succeed or failed. Normal operation may include some intermediate failure messages, such as when a stopped system unit is attempted to be stopped again.

If you are in doubt about whether a message represents a problem or not, discuss it with your system administrator or contact MuleSoft support.
