Report number of active [child?] processes about apache2buddy

[richardforth]

A change has been committed to staging branch for testing.

[richardforth]

Testing went kinda well, (it works) but the display needs prettifying and putting in the right place,

[richardforth]

Testing completed:

Output looks like:

[ INFO     ] Your MaxClients setting is 256.
[ INFO     ] Current Apache Process Count is 18, including the parent PID.
[ INFO     ] Your ServerLimit setting is 256.

(note that number is CYAN or RED if greater than or equal to "maxclients")

Code block:

curl https://raw.githubusercontent.com/richardforth/apache2buddy/staging/apache2buddy.pl | grep -A10 "Check 14.1"

        # Check 14.1
        # Get current number of running apache processes
        # This resolves Issue #15: https://github.com/richardforth/apache2buddy/issues/15
        our $maxclients;
        our $current_proc_count = `ps aux | egrep "httpd|apache2" | grep -v apache2buddy | grep -v grep | wc -l`;
        chomp ($current_proc_count);
        if ($current_proc_count >= $maxclients) {
                if ( ! $NOINFO ) { show_info_box(); print "Current Apache Process Count is ${RED}$current_proc_count${ENDC}, including the parent PID.\n" }
        } else {
                if ( ! $NOINFO ) { show_info_box(); print "Current Apache Process Count is ${CYAN}$current_proc_count${ENDC}, including the parent PID.\n" }
        }
