nagios plugins to check service httpd status

[kaushalshriyan]

Hi,

I have checked on https://exchange.nagios.org regarding monitoring of /etc/init.d/httpd status and could not find any specific plugin to monitor it. For example if status returns failed or not ok nagios should trigger alert.

Code: Select all

service httpd status
Redirecting to /bin/systemctl status httpd.service
● httpd.service - The Apache HTTP Server

Any help will be highly appreciable.

Hi @Kaushal

You can use NRPE to monitor services and processes like httpd. Follow the instructions below for installing NRPE on your sever.
https://assets.nagios.com/downloads/nag ... _Agent.pdf and use check_init_service to determine if httpd is running or not.

Service Checks in Nagios
https://support.nagios.com/kb/article/s ... s-775.html

Please let me know if you are able to get it setup.

Hi Benjamin Smith,

Thanks for your email and appreciate your help. I am running Nagios Core 4.3.4 in my environment and i have already setup nrpe agent on all the client nodes. Is there a way to install check_init_service in /usr/lib/nagios/plugins/ as Nagios plugin?

Code: Select all

# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)
# rpm -qa | grep nrpe
nrpe-plugin-3.2.1-1.x86_64
nrpe-3.2.1-1.x86_64
# ls /usr/lib/nagios/plugins/ -l

I look forward to hearing from you.

attached is the script

You would need to add something like the following to nrpe.cfg

Code: Select all

sudo /usr/lib/nagios/plugins/check_init_service $ARG1$

Also, this plugin required a sudoers entry like the following

Code: Select all

nagios ALL=NOPASSWD: /usr/local/nagios/libexec/check_init_service
