Function Documentation

void cmx_process_update

(

void

)

initialize or update the process information in cmx.

If called in the current process for the first time, this function will create a so-called CMX Process-Component.

Then and at any consequent call, the values in the process component will get updated.

Currently the process component contains the following metrics:

process_name - program_invocation_short_name - value initialized once. process_id - getpid() - value initialized once. hostname - gethostname() - value initialized once. start_time - time() - value initialized once. rusage.{utime,stime,nvcsw,nivcsw} - getrusage() - updated at every call.

In the future more predefined metrics will be added into the process component.

The calling thread must be aware that this function executes syscalls. Do not call it too frequently and never from real-time threads.

Examples:

/demo/example1.c, and /demo/fast-writer.c.
