Issues with node

[Dave-OD]

Hi Folks,

I have two nodes which i think are pretty much identical, but one of them seems to be failing all checks.

When i do a tcpdump on Nagios i only see traffic leaving for one of the nodes, the working one obviously. So would lead me to believe its a config problem with creation of node. I likely just copied the other node, and just changed the obvious details, IP address, host name / address etc.

I can ping both hostnames, and it resolved correctly to the IP, which is also odd.

Could someone take a quick look at the below config and tell me if there is anything obvious i am missing, or any other checks you can recommend, thanks a mill guys

proxy1 is the problem one. proxy2 passes all checks...

Your host and service definitions are missing:

Code: Select all

register                        1

What does the following output:

Code: Select all

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

[Dave-OD]

Hi, thanks for reply... see output.. ive taken out all the host name details.. but seems to run OK!!

Can you elaborate on the "host and service" definition comments, and where they need to be specified??

Code: Select all

nagios@edirlinux:/usr/local/nagios/etc/objects> /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Actually don't worry too much about the register comment, I was thinking about something else (FYI here is some info about it http://nagios.sourceforge.net/docs/3_0/ ... tance.html).

I would like to see your command definition for:

Code: Select all

check_proxy_google
