Hi -- I am a new user of MP2 seeking help. I posted this question earlier to the mod-perl list but not get an answer, so perhaps folks here can offer advice...

Here's my situation: My Apache generates 4 sets of logs. Three of them are generated by Apache directly: access, error, and a custom log tracking access for certain files. The fourth is made w/in a MP2 handler; here's the code:

sub mylog {
    my (@fields) = @_;
    my $entry = join ( "|", @fields );
    open my $fh, ">>" . &MYLOG or die "can't open " . &MYLOG . ": $!";
    flock $fh, LOCK_EX;
    print $fh $entry . "\n";
    close $fh;
}

Currently I'm rolling my logs "manually" -- a process renames the four sets of logs, waits, then restarts the server, waits, moves away the old logs, etc.

I am considering using piped logs with rotatelogs instead to avoid the restart. I understand how to instruct Apache to log via a pipe to rotatelogs for access and error and custom.

My question relate to the mylog() function:

• Can I / should I direct output to a pipe? Would this do anything unpleasant to MP2 or AP2?
• If doing this is OK, do I just open the pipe like a file?

  #untested!
  open my $fh, "|bin/rotatelogs /var/logs/%y_%m_%d_%H_%M_%S 14400" or di
  +e "can't open pipe to rotatelogs: $!";

• I'd remove the FLOCK, yes?
• If I do this, should I close the pipe after use, as I do now in mylog() with close $fh?
• Are there any speed or stability concerns logging through rotatelog, vs. to a file?

Thanks very much for your advice and insights....
