Device Dashboard

Description

(For device administration see Device Administration.)

The Device Dashboard for a managed device in Netreo provides detailed availability and performance information for that device. Every managed device in Netreo has its own Device Dashboard.

To view the Device Dashboard for any given managed device, select the name of the device (or its dashboard icon) from any device list in the Netreo user interface. Lists of devices may be found in dashboard widgets throughout Netreo, or by using the Netreo search box located in the upper right of the user interface.

The Device Dashboard is made up of the following tabs, with each tab focused on specific aspects of the device.

• Overview - A quick view highlighting the most commonly useful data for a device.
• Services - Displays the service checks assigned to the device and their state history.
• Performance - Displays performance graphs for all metrics collected for the device as well as the status of any threshold checks monitoring those metrics.
• Topology - Visual representation of the network topology around the device.
• Trends - Displays time-in-state data showing overall trending of device health status.

The tabs and their contents are explained in detail below. If the device is currently experiencing any problems, the relevant tab will be highlighted in the color of the most severe alarm state.

To the left of the tabs is some basic information about the device. This includes the device name, the device type, the currently polled IP address for the device, and the category and site the device belongs to (both of these last items are clickable links which open the dashboard for each respective device group). To the right of the tabs are the device menus (explained below).

Device Menus

The device menus are a set of pull-down menus located at the top right of the Device Dashboard display. The contents of these menus are contextual and display or change their contents depending on the device type and the access level of the user.

The Reports menu provides quick access to a number of useful device-level reports and tools that can help troubleshoot a variety of problems.

The Grouping menu provides links to the Strategic Group Dashboard of each strategic group that the respective device is a member of, as well as links to the Device Dashboards of the parents and children of the currently viewed device.

Overview

Device Icon and Status

In the top left of the Overview tab is shown the icon representing devices of this type. These icons are how host device types are represented on the topology maps (see Topology Tab below).

Below this are four indicators representing the current number of Netreo monitoring checks assigned to this device that are in the CRITICAL, WARNING, ACKNOWLEDGED and HEALTHY states. If any of these indicators have no checks in that state, they will show a faded 0.

If the device is a virtual resource, information about its host, cluster and hypervisor will appear below the status indicators. These are clickable links that will navigate to the item's respective dashboard.

Host Information

Below the status indicators is the Host Information panel (collapsed by default, click to expand), which contains the following information:

• Current State
  Displays an indicator showing the current reachability state of the host (up or down). Click Status Details to the right of the indicator to open the Status Details dialog for the device.
• Last Reboot Time
  The operating duration since the last time the device successfully booted. If the device has been continuously operating for a very long period of time, and what's reported here seems wrong, it may be that the counter in the device has reached its maximum value and has rolled-over to zero again, like the odometer in a car. Refer to the device manufacturer for more information.
• Type of Device
  The name of the device type assigned to this device.
• Category
  The category this device belongs to. Click category name to open the Category Dashboard for that category.
• Site
  The site this device belongs to. Click the site name to open the Site Dashboard for that site. If the site status feature is enabled, the site's site status is visible here.
• Address
  Displays the physical address location configured for the site to which this device belongs (See the Administration View > Attributes Tab section below).
• Business Workflow(s)
  Displays the strategic groups that this device belongs to. Click a strategic group name to open its dashboard. For users with the SuperAdmin access level, an edit link next to each strategic group opens the edit page for that group.
• Uptime
  Shows the uptime of the host (as a percentage) for the following time frames:
  • Previous Month - From the first day to the last day of the previous calendar month.
  • Month to Date - From the first day of the current month to the present day.
  • 7d - The previous seven days.
  • 1d - The past 24-hours.
• Serial Number
  The manufacturer's serial number for the device.
• Description
  The manufacturer's description for the device.
• Device Information
  Information about the various hardware sub-components of the device, such as serial numbers and software versions. If a Log button appears to the right of the title bar, it means that Netreo has detected and logged hardware changes to this device. Click the button to open a pop-up display showing the change log.

Host Current Issues

Below the Host Information panel is the Host Current Issues panel. This panel displays any open incidents currently affecting this device, sorted by duration (how long it has existed) from shortest to longest. It provides the following three pieces of information:

• Type
  The nature of the respective incident. Threshold check incidents are clickable, and open the Exceeded Thresholds page. Click the icon to the left of an incident type open the Incident View dashboard for that problem.
• Description
  The description (name) of the specific monitoring check responsible for that incident.
• Duration
  The total length of time for which this incident has existed (whether acknowledged, or not). The list is always sorted by duration from shortest (at the top) to longest.

Top Metrics

The rest of the Overview tab displays a collection of what is generally considered to be the most immediately useful information for that device type. This information is selected from the other tabs for display here so that you don't need to dig through them to find it. (However, any information being displayed here can still also be found on the relevant tab of the dashboard.)

If the device is a router or a switch, and the Zoom feature (see Administration View > Instances Tab below) has been activated for any of that device's interfaces, graphs for those interfaces will be shown at the top of the display.

For statistics displayed in this area that have had a threshold check configured for them, the color of the statistic display will reflect the current state of its threshold check. Additionally, a small star/asterisk icon will appear to the left of the statistic value. This icon will reflect the current state of its anomaly check, if one is configured. If no anomaly check is configured for this statistic, the icon will appear gray. If no threshold check is configured for this statistic at all, the background will simply appear white. Note that statistics are recorded and displayed for each device regardless of whether a threshold or anomaly check is configured for them.

Services

The Services tab provides current status and history on all service checks added to this device. It contains two sections, the Services List panel and the Services State History panel.

Services List

This panel shows all of the service checks currently assigned to this device. (This is not a list of services currently running on this device.)

In the top right corner is a tactical overview-style status indicator displaying the number of service checks currently in each state on this device.

Below that is the service check list. Each entry shows the name of a service check assigned to this device, its current state, its most recent output to the history log and the length of time the check has been in that state. If the state shown is CRITICAL, a link icon appears on the far right of the listing. Click this icon to open the associated incident in its Incident View dashboard. Click the down arrow on the right side of the listing to expand the entry and display the state history log for that service check. Click the check name itself to see a modal dialog displaying a variety of detailed information about the service check itself.

Services State History

Below the Services List panel is the Services State History panel. This log shows an aggregate history of all service check state changes for this device.

• Description
  The service check on this device that changed state.
• Time
  The timestamp the state change occurred.
• State
  The state resulting from the state change.
• State Type
  Indicates whether the check was in a period of rechecking to confirm the state (SOFT) or had generated an alarm (HARD)—for CRITICAL states only.
• Incident ID
  Provides a clickable link to the incident opened as a result of an alarm. Clicking the link opens the Incident View dashboard for the incident.
• Output
  The output of the completed check. This output goes into the history log for this device. This is also the text that will appear in an associated alert notification that uses the {OUTPUT} macro.

Enter terms into the search boxes at the tops of each column and press the Enter key to filter the table. Delete the terms and press the Enter key again to restore the list.

Performance

The Performance tab is where all collected performance statistics are displayed.

The navigation panel on the left provides quick access to the list of collected statistics on the right. Selecting an entry in the navigation list will scroll to that entry on the right and expand its display.

All statistics feature a small graph on the left side showing their performance over the last 24 hours, with the peak value for that time shown above the graph. To the right of the graph are three cards displaying the current, average and maximum values for that time period. At the far right of the statistic is a graph icon which opens the statistic in a full-page graph that provides complete filtering options.

Displays on the right will stay expanded until closed or the page is navigated away from. Entries are color-coded according to their state in both the navigation list and the display list.

Topology

The Topology tab displays a visual representation of the immediate layer 3 parent/child relationships of this device.

Placing the mouse cursor over any of the device icons will display the status of that device. Clicking an icon takes you to the Topology tab of the device dashboard for the clicked-on device, allowing you to follow a network path. Click Back to retrace your steps backwards as you click forward through the network hierarchy. Buttons at the top left of the map allow you to zoom in/out.

The left side of the tab displays the same information as the left side of the Overview tab (above).

QoS

The QoS tab displays Quality of Service data for the particular device. The tab contains four panels, outlined below.

Outbound

The Outbound panel shows data for outbound peak bandwidth and dropped bits for each interface of the device.

Click an interface name to navigate to a report for that interface that includes graphs for bandwidth, errors, post-policy bits, dropped bits, queuing discards, current queue depth and traffic flow through the interface. This report will only show graphs for one output policy at a time. Use the filtering options in the report to change the report time frame and select which output policy to view (see Fig.1 below).

Inbound

The Inbound panel shows data for inbound peak bandwidth and dropped bits for each interface of the device.

Click an interface name to navigate to a report for that interface that includes graphs for bandwidth, errors, post-policy bits, dropped bits, queuing discards, current queue depth and traffic flow through the interface. This report will only show graphs for one output policy at a time. Use the filtering options in the report to change the report time frame and select which output policy to view (see Fig.1 below).

QoS: [Interface]

This graph shows post-policy bits for the interface named in the panel header.

The reference time at the top of the graph indicates when the graph was last updated.

The graph can be printed or exported to various image types using the small button at the top right of the panel.

This panel will always show the interface whose traffic is distributed across the largest number of traffic classifications configured on the device. (This is not necessarily the interface with the largest traffic volume.)

QoS: [Interface] Dropped Bits

This graph shows dropped bits for the interface named in the panel header.

The reference time at the top of the graph indicates when the graph was last updated.

The graph can be printed or exported to various image types using the small button at the top right of the panel.

Below the graph is a table displaying the traffic classifications configured on the device. For each classification, max, average and current bits per second values are shown for post-policy and dropped bits.

This panel will always show the interface whose traffic is distributed across the largest number of traffic classifications configured on the device. (This is not necessarily the interface with the largest traffic volume.)

Trends

The Trends tab shows time-in-state data for the device.

Graphs near the top show aggregate time-in-state values for the previous 12 months, while the Alert Details panel shows recent alert conditions for the past 24 hours, 7 days and 30 days.

Click Report Options at the top to change the time frame from which the data is generated. If you have added custom times to the standard Netreo time frames they will be available as well.
