I have a quite fresh install of the Apache (2.2.3/Centos) + PHP(5.1.6) and following problem: I need to monitor life of one process and in order to do that I run:
$last_line = exec('ps -C snmpd');
and check its output.
Unfortunately I always get nothing. I've checked it with other process names and it seems it can 'see' only Apache's processes.
Any idea how to work this out?
Execution of the other command
system('snmpget -v2c -c public localhost '.$oid, $retval); works great, there is only problem with the
ps. What is strange (for me), when I log as
apache user and run
ps manually it works correctly (shows everything).
