Hi --
I am a new user of MP2. Pardon my basic questions.
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 file types.
The fourth is made by a MP2 handler dealing with
redirects. Here's the snippet of relevant 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.
I am considering using piped logs
http://httpd.apache.org/docs-2.0/logs.html#piped
with rotatelogs
http://httpd.apache.org/docs-2.0/programs/rotatelogs.html
instead to avoid the restart.
I understand how to instruct Apache to log via a pipe
to rotatelogs.
My questions 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 code>
open my $fh, "|bin/rotatelogs
/var/logs/%y_%m_%d_%H_%M_%S 14400" or die "can't open
pipe to rotatelogs: $!";
</untested code>
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 a rotatelog, vs. to a file?
Thanks very much for your advice and insights....
