What authentication mechanism is being used? There are a *bunch* of different authentication mechanisms out in the wild. It would depend on the specific authentication/session management system your website is using. Are you looking to validate whether or not a user *can* login to a website, or are ...

Shy of rebuilding check_disk, you could probably write a wrapper script in Bash pretty easily to translate stdout matching "permission denied" and a return code of "CRITICAL" to "UNKNOWN" or some other output more convenient for your use case. I'd be happy to give point...

Strictly speaking, you shouldn't actually need to call a specific remote NRPE command to get the version info back. check_nrpe can do that natively: [root@capra_nag linux-nrpe-agent]# /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1 NRPE v3.2.1 [root@capra_nag linux-nrpe-agent]# echo $? 0 And it sh...

This presumes that the reader has one. I unfortunately do not.

Could you describe a little more in-depth what it is you're trying to do? Also, what family of device(s) you're trying to configure? Model numbers, firmware/software versions, etc.

This is a Production environment server and Application teams will rely on this instance to report them any errors in their applications. +1 for licensed support :) And if you do have a licensed support contract, I'd suggest putting urgent issues in the customer section or submitting them as an ema...

The check_listen_tcp_udp can check the port status, but if the server exist many port is very hard to configure since i need to configure many plugin command on the nrpe.conf. check_multi is one way to work around that constraint. This plugin can check a TCP port range: https://github.com/gavincarr...

A lot of folks have done hot/cold setups with DRBD , both with Nagios Core and Nagios XI. For centrally managing the configuration, I know of options for Puppet, Chef, and Ansible: https://forge.puppet.com/thias/nagios https://supermarket.chef.io/cookbooks/nagios https://github.com/sadsfae/ansible-n...
