ProbeVue command

The probevue command starts a dynamic tracing session or a ProbeVue session.

The probevue command starts a dynamic tracing session or a ProbeVue session. The probevue command takes a Vue script as input reading from a file or from the command line and activates a ProbeVue session. Any trace data that is captured by the ProbeVue session can be printed to the terminal or saved to a user-specified file as per options passed in the command line.

The ProbeVue session stays active until you type a Ctrl-C on the terminal or an exit action is issued from the Vue script.

Each invocation of the probevue command activates a separate dynamic tracing session. Multiple tracing sessions can be active at one time, but each session presents only the trace data that is captured in that session. Concurrent sessions are generally unaware of each other.

Running the probevue command is a privileged operation and non-root users needs privileges to initiate a dynamic tracing session.
