Vue programming language

The Vue programming language provides your tracing specifications to ProbeVue.

The Vue programming language provides your tracing specifications to ProbeVue. A Vue script or Vue program is a program written in Vue. You can use a Vue script for the following purposes:

• Identify the probe points where a probe is to be dynamically enabled.
• Specify the conditions, if any, that must be satisfied to cause a probe to fire.
• Specify the actions issued, including the trace data that you want to capture.

In short, a Vue script tells ProbeVue where to trace, when to trace, and what to trace. Vue scripts should have a file suffix of ".e" to distinguish them from other file types.

Note that Vue is both a programming and a script language: it is a dedicated dynamic tracing language. Vue supports a subset of C and scripting syntax that is most beneficial for dynamic tracing purposes.
