At the beginning of this good practices series, we present a functionality about host groups but there are many functions for host groups and service groups. To manage these functions can help the user to optimize using them but using Centreon as well.. This article aims is to present different case-studies to get the best of your Centreon plateform.
A host group rationally contains several hosts and service group, several services. It means all elements in the group have the same noticeable characteristic. For example: the host group “WindowsServer” contains all Windows servers.
Host group use cases
In the monitoring interface, we use host group as filter for researches.
We also use them in the monitoring view to visualize the state of all services from the same host group :
So, host groups can be used to visualize or filter the display. We also use those to filter access while configuring ACLs.
Therefore, groups can be based on admin team organization and/or geographical situation. A host group will be created for each admin team and all equipment from this team will be included in the group. Moreover, a group will be created for each geographical situation and all equipment from this situation will be included in this group.
To make the display easier, groups will be created with the same type of elements and being able to :
- Only look the groups which you are interested in
- Differentiate geographical situations
- Differentiate operating systems
- Differentiate hardware …
Host groups are also used in Centreon reporting interface :
The case study here is a little bit different: we want to have some availability information about equipment group. We have to compare different elements between each other:
- Is there the same availability between Cisco equipment and Huawei equipment?
- Are Linux servers as efficient as AS400 servers?
So, created groups will be :
- reporting by administration team
- reporting by operating system
- reporting by hardware
- reporting by trademark and/or template
- reporting by geographical situation
- reporting by server type (infrastructure, database, application servers, …) …
Service group cases
Concerning service group, they are used:
- Mainly for reporting
- In the monitoring but not for filters
The main service group case studies are:
- The applications reporting: « Oracle database » vs « PostgresSQL database », « JBoss servers» vs « Websphere servers », …
- The application reporting defined by « composite applicative based on several different services » : « ERP », « flow management », …
Do you think of any other case study?
