Hi all, I'm wondering why on a busy hosting server with hundreds of PHP-FPM workers running in jails "dtrace -l" on the host does not show any PHP specific probes. PHP *is* compiled with dtrace support for all the jails. Enabling /dev/dtrace/* via devfs.rules for a specific jail and then repeating the process *inside* the jail works as expected. Shouldn't jailed processes be transparently visible from the host system but not vice versa?
