Broken Link on Nagios Library - Integrating SNMP Traps with

[metalheat]

We are currently trying to implement SNMP traps on our NagiosXI Server for receiving and processing. After searching nagios exchange we found information regarding the integration of SNMP Traps and Nagios XI. Nevertheless the article points out to a documentation that is not currently available on the Nagios Library and appears to be a broken link. Can you please point us out to where we can find this information or post it.


NagiosXI Server version is 2009R1.1G

Ohh, yes you don't want that... or rather what that was.
Attached is current SVN HEAD, not official or supported.

We are just talking about publishing this.

Mmestnik, thanks for the update, yet the document posted has an .odt file which is missing the images they appear to be broken links also, do you have a local copy of the document with the images?

Thanks again

Also, the script halts after restarting snmptrapd. Please see attached file.

The next step reconfigures the firewall, you likely got disconnected? This prints some things b4 doing anything though.
Is /etc/sysconfig/iptables not a file, link, or directory by chance?

My guess is that the service is failing to daemonize properly. This didn't happen in testing, though as I said this is still a WIP that you don't want to try and use.

We do not use IP Tables on our server. This might be the reason, any other suggestions as to how we can receive SNMP Traps on our Nagios XI Implementation?

[tonyyarusso]

Do you use something else in place of iptables, and if so, what? Or do you just have no firewall rules at all? Nagios XI itself should have tried to set up some iptables rules during installation, so I'm surprised you didn't have issues before.

[mmestnik]

These scripts expect a default CentOS/RedHat deployment and the results of our installation script. If you have made other changes to your server then your are responsible for maintaining these changes.

You can remove a few lines of code from our script to that end.

[metalheat]

We do not run IP Tables or any other firewall on our Nagios XI server since it is running on a closed environment. Nevertheless the problem is showing up far before the IP Tables addition, since it happens after restarting the SNMPTRAPD service not the SNMPTT it doesn't even get to create the appropriate folder information for the SNMPTT program. It appears to get stuck when downloading the PERL on the yumperlget function.

[mmestnik]

That's correct, my mistake.
Try having bash trace it's execution, like so:

Code: Select all

( set -x; . <PathToScript, I.E. starts with ./>; )

I prefer copy/past or text attachments over images.

Another simpler test:

Code: Select all

( set -x; # Install prerequisite Perl modules
function yumperlget () {
 yum provides perl"($1)" |
   awk '/^Repo/ { print pkg "\t" $3; next; };
   /^[^ ].* : / { pkg = $1; next; };' |
   # Here we write our guidelines for pkg selection.
   sort -r -n | cut -f1 > /tmp/perl-package-versions
 topver=$(head -n 1 /tmp/perl-package-versions)
 if [ $(wc -l /tmp/perl-package-versions | cut -d\  -f1) -ge 2 ]; then
   for i in $(tail -n +2 /tmp/perl-package-versions); do
     if [ $(rpmdev-vercmp $topver $i | grep -c newer) -ge 1 ]; then
       topver=$(rpmdev-vercmp $topver $i | grep newer | cut -d\  -f1)
     fi
   done
 fi
  yum -qy install $topver
}
yumperlget "SNMP"
yumperlget "Config::IniFiles"
)
