I haven't modified the code logic in a while and there were no bug reports, so most likely something wrong happens at the Apache::Scoreboard level. Simply try to debug it and compare with what mod_status reports. Both mod_status and Apache::Scoreboard use the same source of information. what platform, perl version do you have this problem on? __ Stas BekmanJAm_pH --> Just Another mod_perl Hacker http://stason.org/ mod_perl Guide ---> http://perl.apache.org mailto:[EMAIL PROTECTED] http://use.perl.org http://apacheweek.com http://modperlbook.org http://apache.org http://ticketmaster.com

Well as you've probably figured out it's not an Apache::VMonitor problem, since it doesn't do much but reading the data from Apache::Scoreboard and formatting it nicely. Does your mod_status show valid data in the extended mode?

Maybe adding this to your httpd.conf will help: ExtendedStatus On ?

I'm sorry, I was away and didn't have a chance to answer mod_perl emails
yet. I saw your post at the list.
It seems that you and me have the same system. Mine is linux RH6.1
apache1.13 mod_perl1.23 perl5.005_03. And it works Ok.
Your problem has nothing to do with Apache::VMonitor, since it relies on
Apache::Util to work. You should post a proper bug report to the list. By
proper I mean asking for help with Apache::Util and not Apache::VMonitor,
so the right people will look into it.
You should try this script:
my $r = Apache->request;
$r->send_http_header("text/html");
use Apache::Util ();
print Apache::Util::escape_html("");
If this doesn't produce "" and produces the same errors, you have
some problem with Apache::Util. Did 'make test' pass Ok when you have
installed mod_perl?

Re: Apache::VMonitor

Yup, I send packets with negative polarity, it's like electricity: holes and atoms, donors and acceptors. That way my ISP pays me for using his net duct, instead of me paying him. Didn't you know that trick, you don't have to pay your electricity bills if you hack the electricity counter to rotate in the other direction... Seriously, I've noticed that. It's a bug and will be fixed in the next version... But, the NetLoad segment is not so useful, but the errors and collisions part... The top() and df() functionality is the main reason for using it. ___ Stas Bekman mailto:[EMAIL PROTECTED]www.singlesheaven.com/stas Perl,CGI,Apache,Linux,Web,Java,PC at www.singlesheaven.com/stas/TULARC www.apache.org & www.perl.com == www.modperl.com || perl.apache.org single o-> + single o-+ = singlesheavenhttp://www.singlesheaven.com
