Overview of common objects in Nagios

Object (Objects) is the basic logical component of the Nagios Monitoring and Notification mechanism, which mainly includes:

Service

Service Groups

Hosts

Host Groups

Contacts

Contact Groups

Commands

Time Periods

Notification Escalations

Notification and Excution Dependenicies

Hosts and host groups: hosts are usually physical devices in the network, with at least some kind of access address (hostname, IP address, or MAC address); each host usually provides one or more services (service); hosts can form parent / child (parent/child) relationships with each other to describe "subordinate" or "inclusive" relationships ("network reachability" relationships) between hosts. A host group usually refers to a combination of one or more hosts.

Service and Service Group (Service/Service groups): "Service" is the core of Nagios monitoring logic and is usually subordinate to a host. It can be the attributes of the host (such as CPU load, disk space, swap space utilization, etc.), a "service" provided by the host (such as POP3, HTTP, SSH, etc.), or even host resources such as DNS resource records. A service group usually refers to a combination of one or more service definitions.

Contact and contact Group (Contacts/Contack Groups): "contact" refers to the recipient of the "notification". Contacts usually have one or more "notifications" (such as mobile phones, Email, instant messaging accounts, etc.) to receive notifications from hosts or services within their scope of responsibility. "contact group" usually refers to a collection of one or more contacts.

Time period (Timeperiods): a "period of time" usually defines a valid period of time that controls when hosts and services are monitored and when contacts can receive notifications.

Command (Commands): used to define programs, scripts, and so on that can be called by Nagios, as well as the calling format of these programs or scripts.
