The main Network Analysis –> Issues page provides both the Network Scorecard and the Select Device Groups right pane. To quickly narrow down possible sources of the largest numbers of Issues, simply click a device group in the page. The Scorecard and the Issues table refresh to show only the Issues contents for the chosen device group. As an example, one device group, such as Network Management, might have an Overall Score of 10.0, indicating no problems, while the Routing device group might have an Overall Score of 8.8, indicating a substantial number of Issues in that layer of the network.

The Select Device Group pane on the Network tab, as well as on the Dashboard tab, Analysis tab displays only extended device groups, unlike the other tabs that display all groupsi.e. groups that allow for calculations. |
The system classifies Issues in three severity levels, along with a fourth scripting-related classification as follows:
...
NetMRI performs analysis of collected data during specified periods or in real-time. For issues processed during an analysis period, the system analyzes all network data collected since the last analysis process, looking for anything that might indicate an issue. For real-time analysis, NetMRI checks for issues while it collects data from the device. If an issue is found, it is raised immediately. As a result of analysis activity, NetMRI generates a collection of issues that summarize the type of problem discovered and all the devices or interfaces associated with that issue. Issues are automatically closed every night just before the new analysis processing is performed. If the same problem persists, NetMRI generates a new issue.
