check_hostgroup command

[ttsvetanov]

Hello, everyone!

I’d like to share a Nagios plugin I created for monitoring hostgroups. This plugin enables precise monitoring by checking the percentage of hosts in a DOWN state within a hostgroup.

This plugin is very useful when working with a host group containing many devices. If notifications are temporarily disabled to avoid spam caused by frequent status changes (e.g., when a client turns off their devices at night), the plugin allows you to receive a notification in case of a serious issue. For instance, in the event of a central failure causing a large number of devices to go offline, you will be alerted when too many of them transition to offline mode. Personally, I have configured critical situations to forward notifications directly to Telegram.

You can download it and check more info here:
