Package: munin-node
Version: 1.4.5-3
Severity: normal
File: exim_mailstats
symptom: munin node returns nonsense values like these:
# munin node at srv1.smtpcorp.com
fetch exim_mailstats
received.value DMK
completed.value DOM
rejected.value FBT
when this is encountered a work-around is to edit the
var/lib/munin/plugin-state/exim_mailstats-*
files and replace the upper-case letters after line two with 0
eg:
sed '3,$ s/[A-Z]*/0/' -i /var/lib/munin/plugin-state/exim_mailstats-*
This causes it to begin outputting numbers, I don't know if the
numbers are correct.
exim has the follwing set. which may effect the log file content
sufficiently to confuse the plugin:
MAIN_LOG_SELECTOR=+smtp_confirmation -skip_delivery -retry_defer
the bug could to be line 221:
221: $received = $completed = $rejected = 'U';
which could be changed to
221: $received = $completed = $rejected = '0';
or possibly these lines:
118:$received++;
121:$completed++;
124:$rejected++;
which if changed to
118:$received+=1;
121:$completed+=1;
124:$rejected+=1;
also results in sensible behaviour
the problem seems to be the difference between ++ and +=1
jasen$ perl -e '$a='U' ; $a ++ ; print $a\n;'
V
jasen$ perl -e '$a='U' ; $a +=1 ; print $a\n;'
