duplicate email seeing two nagios running

Post by zaanen »

Hi all,

i have a strange problem and i try to figger out what is wrong.
When i stop nagios i see nothing is running. When i restart nagios i see 2 deamons and 4 workers.
This result probably in sending double emails to our contact groups.
We have only 1 contact group.

root@server:~/downloads# /etc/init.d/nagios stop
[ ok ] is running.
Stopping nagios:
root@server:~/downloads# ps -ef | grep nagios

Starting nagios:
look like messages from an old or modified version of the init script. Did you run

Code: Select all

make install-init
when upgrading to Core 4?

Also, the number of 'nagios' processes is normal:
pid 25129 is the main process that starts the others and runs the event loop.
pids 25130 to 25133 are four worker processes started to run checks.
pid 25134 is the command file worker that reads from nagios.cmd.

Does each member of the contact group get duplicate emails or only certain ones? Are any email addresses listed twice?

Do you see double notifications under Reports > Notifications? If so, can you share a screenshot of them? If not, it may be duplicated on your mail server's end for some reason, or between the two.

I might be missing it, but that does not look like duplicates to me, seems that its just multiple log entries about the same message relaying through different relays. Also if you are not seeing these in the nagios notifications log, it is likely sendmail or the end mailserver somehow duplicating them, again this log would seem to support that, unless the duplicate relay logs are really where and how it is causing multiples.
