Informix Monitoring

[scottwilkerson]

I just looked at your previous post

Code: Select all

[root@huey libexec]# netstat -na | grep 5666
tcp        0      0 192.168.1.42:10022      192.168.1.49:55666      ESTABLISHED

this is not nrpe listening on 5666, this is something else

Do you have the following file?

Code: Select all

ls -al /etc/xinetd.d/nrpe

How/when did you install nrpe? It may not be using xinetd, what do you get if you run this?

Code: Select all

service nrpe status

We are using nagiosXI not sure if that makes a difference or not. Here is the output of what you asked

[root@huey /]# ls -al /etc/xinetd.d/nrpe
ls: cannot access /etc/xinetd.d/nrpe: No such file or directory

root@huey /]# service nrpe status
Redirecting to /bin/systemctl status nrpe.service
Unit nrpe.service could not be found.
[root@huey /]#


is this using something else? As you can see from the picture below this server and others are being monitored.

[scottwilkerson]

Did you install the NRPE agent on the remote system?

I thought it was installed, but maybe its not now. How could it be monitoring the other two things if it was not installed?
I send you a screenshot is that something different?

You are only monitoring Ping on huey

Ping doesn't require an agent

ok this makes since. I just checked the servers and NRPE agent has not been installed.
When I install these agents I put the IP address of the nagios server when asked correct?

I have a question. I will install this it is a production environment so if it causes issue which I don't expect it to, how can I uninstall it?
Just need to make sure I know how to do this. I see ./fullinstall however don't see a uninstall

There isn't a uninstall script for the agent, however you can simply remove the xinetd service file and restart

Code: Select all

rm -f /etc/xinetd.d/nrpe 
service xinetd restart

Removal of all file added can be accomplished with the following on the client

Code: Select all

rm -rf /usr/local/nagios

[donnyforbes]

I installed the NRPE agents on each remote server. From the server running nagios I ran the following command below, but it did not work

Code: Select all

[root@nag etc]# /usr/local/nagios/libexec/check_nrpe -H 192.168.1.42 -c check_informix
NRPE: Command 'check_informix' not defined
[root@nag etc]#

Please advise is there a file or something I need to update or add a command to? If so what server do I do it on the NAGIOS server or the remote servers?

Thanks

[donnyforbes]

I do see this on the nagios server in the /usr/local/nagios/etc/nrpe.cfg file

Code: Select all

command[check_informix]=/usr/local/nagios/libexec/check_informix.sh

[donnyforbes]

I did fine another one that was in the NRPE.cfg file called this below and it worked fine.

Code: Select all

[root@nag libexec]# /usr/local/nagios/libexec/check_nrpe -H 192.168.1.42 -c check_procs
PROCS OK: 669 processes | procs=669;;;0;

is there something wrong with the my command in the nrpe.cfg file? Please advise
