NetMRI is a network management interface to analyze and monitor devices and enterprise networks, their protocols, and their configurations from a convenient Web browser window. The primary browser pages are called the NetMRI Dashboards. The Dashboards are your home pages for managing devices on the network. The Dashboards provide easy access to tasks and to the status of the networks.
NetMRI provides a layered system of tabs to access and operate features of the software. The top layer of the NetMRI tabbed interface provides the six key functional areas of the software, consisting of the following pages.
...
The Dashboard tab provides information summaries, nerwork analytics, and system healh data. It includes the following sub-tabs:
...
The Dashboard tab provides three high-level summaries of information and network analytics, selectable from the Select Dashboard menu at the top of the page. See the following:
...
- 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.
...
- 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.
...
| Note |

In the Timeline Status Summary dashboard, the zero value in the Issue Variations chart's Y-axis corresponds to the average number of issues for the shown time period. |
The main Dashboard page and Network Analysis > Issues pages display the Network Scorecard, which is a quick-glance guide to the overall status of all Issues in the managed network.
See About the Network Scorecard for more information about this tool.
...
To change the scope of information displayed in the Dashboard, select an item in the Select Device Groups pane on the right.

The Select Device Group pane on the Dashboard tab displays only extended device groups, i.e. groups that allow for calculations. |

The Performance Dashboard displays charts with important metrics of the NetMRI performance and health. Using this information, you can more flexibly assign resources to your NetMRI VM to accommodate device count scaling.
You can choose from the following dashboards on the Performance tab:
To open a dashboard, click the dashboards menu in the top right of the Performance tab and select the required one. For more information, see Dashboard Display Options.
When a dashboard displays its chart(s), hover over a chart name to see its description in the tooltip.
You can use a calendar in the top left to view metrics statistics for a selected day, week, or month. The selection can also include 7-day and 30-day periods.
Also see Performance Data Retention and Backup.
...
There are two dashboard categories to display:
- Basic
- Advanced
To display only basic dashboard categories, click the Settings icon > General Settings > Performance Dashboard > Show Advanced Categories and set the value to "false". Setting the value to "true" enables displaying both categories.
On OC deployments, you can select the unit for which to display dashboards – OC or any of its collectors. To do so, click OC in the top right of the Performance tab and select the required unit.

The following rules apply to the performance dashboard data retention:
- Data is stored in weekly historical partitions.
- Data is archived after one month.
- Data is deleted after 18 months.
To change data retention times, click the Settings icon > Database Settings > Data Retention > Performance Dashboard Data.
To archive the performance data during a database backup, click Settings icon > General Settings > Advanced Settings > Performance Dashboard and set the Add Performance tables to the backup option to "yes".
...
Network Analysis also features the Network Scorecard on its front page. Information is organized in four tabs within the Network Analysis page:
- Issues: This tab summarizes the current network status, showing the same scorecard that appears on the main Dashboard, a flexible Network History chart, and an overview of current problems and possible problems in the network.
- Changes: This tab summarizes all recent changes made to the network, and provides features to change the information displayed in the summary table.
- Policy Compliance: This tab summarizes the results of Policies developed in the Policy Compliance features for device groups and active devices in the network.
- Performance: This tab summarizes active device operations in charts and tables.
...
The Network Explorer tab displays everything NetMRI learns about the network. Network Explorer is a good starting point for inspecting the results of a Network Discovery process, viewing the topology of the discovered network, viewing the operational state of individual network devices (through a feature called the Device Viewer), and obtaining views of how the network is behaving in different locations in the topology.
See the following tabs within the Network Explorer tab that offer different ways to examine network data:
- Inventory: This tab provides basic information about devices, interfaces, operating systems, and models in the network.
- Summaries: This tab lists routes (for all routing protocols), subnetworks, Route Targets, Network Views, VRFs (Virtual Routing and Forwarding instances), VLANs, HSRPs/VRRPs, and TCP/UDP port usage in the network.
- Topology: This tab provides an interactive viewer for exploring your network's structure.
- Discovery: This tab provides detailed information about NetMRI's discovery processes, including the ability to affect Discovery settings for individual devices, perform/repeat Discovery on a single device, set licensing for a managed device, and remove a device from NetMRI management. For more information on device-related Discovery functions, see Viewing Device Discovery Status and Re-Discovering a Device.
...
Configuration Management provides a powerful set of features for managing, normalizing, and editing configurations for all devices managed by NetMRI, including the following:
...
pages
...
- Scripts: This tab lists all scripts in the NetMRI system.
- Library: This tab provides a location for CCS and Perl subroutines that can be called by other scripts.

- Rules: This tab allows you to explore the entire library of Policy Rules and provides the ability to create, edit, copy, import, and export Rules.
- Policies: This tab provides general Policy management features, such as editing, printing, and import/export, and test Policies against devices, configuration files, and configuration templates.
- Policy Deployment: This tab allows admins to enable policies against individual devices or device groups.
...
The Reports page provides features that allow you to run publishable reports from providing device information in a report to reports across device groups or types of devices, to network-wide reports indicating trends across the network.
