Service Grouping Statuses

The status of a service grouping is the result of the combined statuses of all the services in the service grouping. The statuses have a priority ranking and a relationship to the formula used when the service grouping was created. The table below lists the default hierarchy of priority for the default service statuses.

The table represents the system default order of statuses. The order of statuses can be changed in MSP N-central by an administrator. To view the hierarchy in your system, go to the NOC view.

Failed, Warning, or Normal Statuses

If a service within a service grouping has a Failed, Warning, or Normal status, the status of the service grouping is dependent upon both the status and the formula.

When the services within the service grouping are in Normal, Failed, or Warning states, the state of a service grouping will depend on whether you use OR or AND in the formula to group the services.

For example, if you use OR to relate two services - Service A OR Service B - the service grouping will display Failed if either of the services is in a Failed state. If you use AND to relate two services, the service will display Normal if the status for one service is Failed and the other is Normal.

If you want to be informed of any services in a service grouping that are in a Failed or Warning state, use OR to set up your formulas. A Warning status resulting from a formula using OR is a good indicator that there is a threat to the service in the future.

The table below lists the some examples of how different formulas are evaluated when services in a service grouping are in Failed, Warning or Normal status.

The table below lists examples of outcomes for services in a service grouping in Failed or Normal states, using AND, OR, and brackets in the formulas.

Formula

Example and Logic

<Service A>

OR <Service B>

SMTP OR POP3

If SMTP status is Failed, the service grouping status is Failed.

If SMTP status is Warning, the service grouping status is Warning.

<Service A>

AND <Service B>

Telnet AND SSH

If the status of Telnet is Failed or Warning, and the status of SSH is Normal, the service grouping status is Normal, and you can still access the computer remotely.

(<Service A>

OR <Service B>)

AND <Service C>

 

(Process1 OR Process2) AND Disk

The service grouping is available only if both Process 1 and Process 2 are running, regardless of whether Disk is available.

The brackets establish precedence in a formula. In this example, the expression <Service A> OR <Service B> is evaluated first.

If the brackets are not applied, the AND expression takes precedence over the OR expression and <Service B> AND <Service C> would be evaluated first.

Misconfigured, Stale, No Data, or Disconnected States

If a service within a services grouping is in a Misconfigured, Stale, No Data, or Disconnected status, the service grouping status is influenced by the service states only, not the formula.
