Here's a bit more info on the problem. I went into the source code and found
that my
config is not making it past the conditionals in this section (starts at line
1923 in
mrtg):
-------------------------------------------------------------------------------
# Check if we use the status file or not...
if ( defined $threshfile ) {
if ( not -e $threshfile.".".$bound.uc($dir) ) {
# Create a file to indicate a threshold problem for
the time
after the problem
open THRESHTOUCH, ">".$threshfile.".".$bound.uc($dir)
or warn "$NOW: WARNING: Creating
$threshfile.".$bound.uc($dir).": $!\n";
close THRESHTOUCH;
if (defined $$rcfg{'threshprog'.$dir}{$router}){
debug('base',"run threshprog$dir: ".(join
",",@exec));
system @exec;
}
threshmail
$cfg->{threshmailserver},$cfg->{threshmailsender},$rcfg->{threshmailaddress}{$router},$message
if $rcfg->{threshmailaddress}{$router}
} else {
debug('base',"NOT acting on BROKEN threshold since
$threshfile.$bound$dir exists");
}
} elsif ( not defined $cfg->{threshhyst} or
($bound eq 'min' and $boundval -
$cfg->{threshhyst}*
$boundval < $threshval) or
($bound eq 'max' and $boundval +
$cfg->{threshhyst}*
$boundval > $threshval)
) {
# no threshold dir so run on every 'break'
if (defined $$rcfg{'threshprog'.$dir}{$router}){
debug('base',"run threshprog$dir: ".(join
",",@exec));
system @exec;
}
threshmail
$cfg->{threshmailserver},$cfg->{threshmailsender},$rcfg->{threshmailaddress}{$router},$message
if $rcfg->{threshmailaddress}{$router};
}
-------------------------------------------------------------------------------
If I tack on a little more code then I get the behavior I expect:
-------------------------------------------------------------------------------
else {
if (defined $$rcfg{'threshprog'.$dir}{$router}){
debug('base',"hack run threshprog$dir: ".(join
",",@exec));
system @exec;
}
}
-------------------------------------------------------------------------------
What I can't figure out is why my config doesn't meet this criteria:
-------------------------------------------------------------------------------
} elsif ( not defined $cfg->{threshhyst} or
($bound eq 'min' and $boundval -
$cfg->{threshhyst}*
$boundval < $threshval) or
($bound eq 'max' and $boundval +
$cfg->{threshhyst}*
$boundval > $threshval)
) {
-------------------------------------------------------------------------------
I don't have threshhyst defined in the config file so that if should evaluate
to
true!! As far as I can find in the code there is no global definition for
threshhyst
that would override the fact that I haven't defined it in my config file.
Anyone have any ideas?
