Remember that “Host groups” in APM are used to group common devices together in order to facilitate the display and the alerts that will be sent when something goes wrong.
For example, if I create a group of hosts called “WINDOWS SERVERS” under which I put all the Windows servers on my network, and Bob is responsible for managing and dealing with alerts received from Windows servers, then if a service or a Windows host under this group is down, Bob will receive the alert of this group and will know for which server this alert applies.
This approach is just a recommendation to facilitate the management of devices on your network. You can put everything under the same group if you like but for better flexibility, it is recommended to create different group and put different devices into them so that it becomes easy to assign a group of hosts to a particular person or group of people responsible for these devices.
How to create Host groups ?
To create new Host groups, go to “APM | Configure | Administration | Supervision | Host groups” and then click on the “Add” button.
Then define a name for your Host group and a description. These two fields are the minimum required for the new Host group to be created.
Note: Don’t forget to activate the Host group by checking the boxes “Registered” and “Active” on the page before clicking the “Save” button.
