How To Fix RT358 - Availability and status of an instance

RT358 - Overview

• Message type: E = Error

• Message class: RT - Monitoring infrastructure MSG and alert texts

• Message number: 358

• Message text: Availability and status of an instance

What causes this issue?

Displays the availability status of a specific instance in a system
that is monitored for availbility. Below this MTE, you will find
further monitoring MTEs that display:
The instance status
The most recent reported status (active or inactive)
The instance summary
The percentage of time that the instance was available over a specific
period of time. This time period is specified in the customizing
options of the instance summary MTE.

System Response

The alert monitor triggers a yellow alert if an instance is not active.
You can specify which instances if any are to be monitored. To do
this, start the analysis method at any MTE in the Instances sub-tree.
Disabling the monitoring of instances has no effect on the monitoring
of the system availability as such. While no instance MTEs will be
provided with availability values, the monitor will still report
whether the system was available: the message server of the monitored
system reported that at least one instance was active.

How to fix this error?
