For a monitoring system to receive more information from an endpoint
|
|
other than that it is simply accessible, help is required from the
|
|
target system. For example - how else can Checkmk know how full a
|
|
server's storage volume is without that system somehow providing the
|
|
information? The component that provides this information is always an
|
|
active piece of software - namely a monitoring agent, usually just
|
|
referred to as an agent. An agent collects data relevant to monitoring
|
|
from a host at specified intervals and transmits that data to the
|
|
monitoring server.
|
|
|
|
For servers and workstations, Checkmk provides its own agents, these
|
|
are known as Checkmk agents. Checkmk agents are available for a wide
|
|
variety of operating systems - from the commonplace such as Windows and
|
|
Linux to exotics such as OpenVMS. The agents are passive and listen on
|
|
TCP port 6556. Only on receiving a Checkmk server query will these
|
|
agents be activated and respond with the required data.
