Beyond monitoring traffic flow and generating alarms every time thresholds are passed, NetMRI periodically analyzes the contents of all router and switch tables to detect device-level problems, such as router and VLAN instability.

  • Timeline Status Summary: This dashboard displays the Network Scorecard (seen here), a numeric metric that provides an at-a-glance overall assessment of the current state of the network. The Timeline Status Summary also provides graphs showing most-changed devices, a policy compliance breakdown, and historical graphs of percent policy compliance, issue variation, and changes:
    • Policy Compliance: This chart shows the daily percentage of all managed devices, as a pie chart, that match against Policy Compliance Rules from the defined Policy Compliance criteria in the NetMRI system. The Percent Policy Compliance bar chart shows the same daily data as a progression from one day to the next.
    • Issue Variation: This chart lists the following data points for the overall daily issue status in the NetMRI system or the Operations Center: The daily Overall Score in yellow, the total issue count and Delta (change in number of Issues; this value can be positive or negative for the time period measurement) in blue; and the number of Added and Deleted Issues in blue. A yellow trendline shows the Overall Score trend over the chart's time period. Green dots at the bottom of the chart are the activity indicators for the measurement time period, showing the number of added or deleted issues. Clicking the trendline opens the Network Analysis -> Issues page, showing the corresponding Overall Score History stacked bar chart.
    • Changes: This shows a bar chart and trendline for specified time increments, with the bar chart indicating the total number of changes, breaking out the administrative and hardware changes for the time period, and the trendline showing the average rate of changes across the entire chart time period.
  • Issue Summary: This dashboard replicates the Network Scorecard, shows a Top Issue Types bar chart and a Top Affected Devices bar chart, and displays historical graphs of issue type and instance trends. 
    • Top Issue Types and Top Affected Devices: These show an overview of Issues that appear most frequently in the managed network, and the devices exhibiting the largest number of Issues.
    • New Issue Types: This table lists all new Issues of specific types that appear for the current time period (corresponds to the #New column in the main Network Analysis –> Issues page).
    • New Issue Instances: This table provides the number of devices affected by each Issue type (this value corresponds to the #Affected value in the main Issues page).
    • Type Issue Trend: This area chart combines sections for severity Info (blue), severity Warning (yellow) and severity Error (red), each of which are links to the main Issues page showing a table only for the issues of the chosen severity type.
    • Type Instance Trend: This area chart combines sections for severity Info (blue), severity Warning (yellow) and severity Error (red), each of which are links to the main Issues page showing a table only for the issues of the chosen severity type.
  • Change Summary: This dashboard shows most-changed types, most-changed models, most-changed devices, number of changes detected over time, and most-active change makers.

Consolidation Time

+++Average processing time of collected data with warning and critical thresholds available in tooltip. Data is collected every 10 minutes.

Consolidation Subscription Queue

+The queue length of subscriptions from collectors awaiting consolidation. Data is collected every 10 minutes.

Consolidation Subscription Delay

+Wait time for data consolidation received from collectors. Data is collected every 10 minutes.

Consolidation Delay

+Time delay between the data acquisition and consolidation for OC. Data is collected every 10 minutes.
