In a nutshell, Business Services is a tool for availability monitoring of logical services. Company email, web site, server farm, call center - all are examples of logical services. Moreover, the services can be combined together to define a "broader" logical service. Company email, web site, name server and firewall all can be referred to as "Company Internet Services" and monitored for availability as a whole. So if the name server goes down then the "Company Internet Services" do not function properly as a whole. This feature can be used both as ....
Service
Business Services represented with a tree-like hierarchy of nested logical services, nodes and service checks. One can think of a service as a container consisting of other services, service checks and nodes linked to service checks. In NetXMS terminology the last is called node link. For each service in the hierarchy, NetXMS calculates availability percentage and keeps track of all downtime cases. To check availability at any particular level, select it in the Object Browser or choose Availability Chart from the context menu.
Node link
A node link is a reference to any node with one or more service checks attached to this node.
Service check
Service check is a test whose result is used to define the state of the service. A service check may belong to the specific node (node link) or directly to the service. A service check object contains NXSL script which either returns success (the test result ok) or failure (the service has failed). There are two special variables which can be used in NXSL scripts for service checks:
- $node - points to the current node the check is being executed for
- $reason - the script may set the reason of failure
