What's "master" here?
Main process - postmaster.
Huh, surely we're not interested in tracking postmaster start?
It depends. See following schema example
postgres::proc-master-start
{
tracking = 1
}
syscall:::open:entry
/ tracking == 1/
{
... print file name ...
}
postgres::proc-master-stop
{
tracking = 0
}
It is very useful because it say when you can start and stop monitoring for
example. But I'm not DTrace expert maybe there is different way how to do it.
