Overview

The Image Map panel allows you to place nodes and links between nodes, and have those nodes/links display configuration, state or timeseries data. The nodes can:

  • Be a simple text label, display an icon, or both
  • Display a timeseries metric or state returned from the entity
  • Utilize conditional coloring of label or icon

Links can:

  • Optionally, display a timeseries metric or state returned from the entity
  • Utilize conditional coloring for an applied label and/or the link itself

Image Map Configuration

The in-panel editing controls are only available to dashboard editors, and can be used to:

  • Add/remove nodes and links in your panel
  • Move existing nodes and re-path existing links

  • Zoom controls – zoom in/out on the panel
  • Add Node – once enabled, click within the panel to add a new node
    • Done – exit mode
  • Add Link* – once enabled, click within the panel to begin a new link, clicking again adds a vertex allowing you to path the link as needed
    • Done – delete current link (if any) and exit mode
    • Finish Link – complete current link (last placed vertex becomes link end-point) and remain in ‘add link’ mode
    • Cancel Link – delete current link (if any) and remain in ‘add link’ mode
  • Edit Mode* – relocate nodes while maintaining all link connections, re-path links by dragging link-handles,
    • Done – exit mode
    • Duplicate – once enabled, click an existing node/link to duplicate the entity
  • Delete Mode* – click any node/link to delete the selected item
    • Done – exit mode

* – requires both dashboard editor permission for the active user account AND the panel-specific option Show Edit Control = enabled (default value)

Managing Links in Edit Mode

Entering Edit Mode will display link handles at each end-point and vertex. Markers are also displayed at the mid-point of each link segment.

  • Drag a link handle to re-path the link
  • Left-click a mid-point to convert it to a vertex (creating new midpoints)
  • Right-click to delete the handle, simplifying the link

Clicking the panel header opens the panel menu, offering the following options:

  • View – view the panel in fullscreen mode
  • Edit – edit the panel configuration
  • Share – options for sharing the panel contents with others, both internal and external to your organization
  • More
    • Duplicate – place a duplicate of the panel on the current dashboard
    • Copy – copy the dashboard configuration in order to add the panel to another dashboard
    • Panel JSON – view/edit the JSON underlying the panel configuration
    • Toggle Legend – show/hide the legend
  • Remove – delete the panel from the dashboard

You can edit the panel configuration by:

  • Clicking the panel title to open the panel menu and selecting Edit

Panel Configuration Best Practice

General Image Map Construction

When the image map will display multiple instances of output from any one query:

  • Place and completely configure a single node/link (units, appearance, labels, conditional coloring, etc.)
  • Duplicate this node/link updating the target entity (and label/icon) as needed

The in-panel editing tools allow you to begin your panel configuration by adding and positioning nodes, generating links between nodes, and then working through the node and link configurations one-by-one – generally, this will not be the best way to proceed.

Image maps may utilize multiple queries, and typically display multiple instances of output from any one query. For example, if your image map is displaying Ping RTT there will typically be multiple nodes displaying Ping RTT for a range of network devices.

Rather than placing nodes and then configuring each individually, it is more efficient to completely configure a single node and then duplicate this node, updating the configuration as needed, in many instances the only required update will be the target entity.

Link Positioning/Pathing

When positioning links, the link ends will snap to attachment points on the nodes (attachment points can hold any number of links), this ‘snapping’ behavior can be overridden by holding the Alt key while positioning the link.

While in Edit Mode:

  • Drag a link handle to re-path the link
  • Left-click a mid-point to convert it to a vertex (creating new midpoints)
  • Right-click to delete a handle, simplifying the link

General

The General tab is used to configure the panel title, description, and panel-level links.

  • Title – the panel title, displayed at the top
  • Description – the panel description, displayed on hover of info icon in the upper left corner of the panel
  • Transparent – if checked, removes the solid background of the panel (default not checked)
  • Repeat – repeat a panel for each value of a variable, see Variables for details
  • Drilldown – configure panel-level links displayed on hover of info icon in the upper left corner of the panel
    • Type – link to a Statseeker dashboard or any URL
    • Dashboard/URL – the dashboard or URL to link to
    • Title – the display name for the link
    • URL params – key=value pairs to be appended to the end of the URL as parameters
    • Include time range – include the current panel time range as a URL parameter
    • Include variables – include all dashboard variables as key=value pairs to be appended to the end of the URL as parameters
    • Open in a new tab – open the linked destination in a new tab

Image Map

The Image Map tab is used to configure the appearance of both the panel and the data displayed within the panel.

Background Settings
  • Background Type – Specify the panel background
    • Color – a solid color background
    • External Image URL – an image resource hosted externally to the Statseeker server

The Label configuration requires that Appearance > Show Label is checked. This configuration specifies the appearance and content of the optional link label.

  • Label Mode –
    • Follow Link – the label orientation will follow the link pathing
    • Static – the label orientation is independent of the link orientation

  • Label Position – distance (percent) along the link that the label will be displayed, 0 = link start, 100 = link end

  • Regex – requires Metric Type = String, specify a regex filter, and the color to apply to values satisfying that filter
  • Value Map – requires Metric Type = String, specify the matching string Value, the Text to display instead of that value, and assign a color to apply in that instance
  • Range – requires Metric Type = Number, assign the start and endpoints of the range, and a color to assign when values fall within that range
Note: when multiple ranges are specified, the endpoint of the lower range should be the same as the start point of the upper range. The upper range color will take precedence over the lower range color.

In the above configuration, 0-79.99. will be green, 80-94.99. will be orange, and 95+ will be red.


Drilldown

Optionally, configure an HTML link to be triggered on click of the link object.

  • Type – set HTML link type: disabled, dashboard or absolute
  • URL – for absolute HTML link
  • Dashboard – requires Type = Dashboard, select from the list of existing dashboards

  • Include variables – check to pass the current values of dashboard variables, as URL parameters, to the HTML link target
  • Open in new tab – check to open the target in a new tab

[top]

Time Range

Apply an override to the dashboard-wide timefilter. Panels with time range overrides refresh, but do not alter their timefilter, when a user:

  • Alters the dashboard time filter settings
  • ‘Zooms in’ on a graph panel on the same dashboard, changing the timefilter applied to the dashboard

Using panel specific timefilter overrides allows you to easily create dashboards which compare the same data (entity and metric) for different time ranges:

  • Today vs yesterday
  • This week so far vs last week

  • Override relative time – specify a time range for the panel
  • Add time shift – Amount – override the ‘now’ point with respect to the timefilter being applied to the graph
  • Hide time override info – when unchecked, the current time override setting is displayed in the top-right of the graph header

Example Configuration – image background and multiple queries

This example will illustrate the query and panel configuration used to produce the ImageMap panel presented below.

Metrics Tab

The panel presents 3 different metrics (CPU load, Memory Load, and Temperature), so the Metrics tab contains 3 queries, 1 for each of these metrics

Image Map Tab

Each node presents data from one of the queries defined in the Metrics tab.


[top]

Example Configuration – network topology using nodes and links

This example uses both nodes and links to present a basic office topology.

Metrics Tab

Four queries returning:

  • Current Device Ping-State
  • Current Interface Utilization (Rx/Tx), when configuring links we will be focusing on the dedicated links between the device nodes
  • Current CPU Load, aggregated (averaged) across all CPUs on the device
  • Current Temperature (C), aggregated (averaged) across all temperature sensors on the device


[top]

Image Map Tab

Background, View, Global and Legend Settings

Node Configuration

Configure a single Device Ping-State node, then duplicate the node, updating the target Data > Entity and Appearance > Icon, and reposition as needed to populate the panel.

  • Set Appearance > Type = Icon and assign an icon to suit the target device type
  • Label > Include Field = unchecked as we are using coloring rules to indicate the device state, so we don’t need to display the device state in the label
  • We have configured a Drilldown link for the node, pointing the Device Overview dashboard, passing through the Label (${__label}) to the Device variable in that destination dashboard. The Label references the content of the Data > Name field.

Once a single ping-state node is configured we can duplicate the node configuration to create additional nodes. We only need to update the Data > Entity and Appearance > Icon fields for the duplicated nodes, speeding the process of populating the image map.

Note: When in editing node\link configurations, click to select a node\link will highlight that item and display the configuration block for that selected node/link.

Returning to the dashboard view and enabling Edit Mode allows us to easily position our nodes within the image map panel.

Repeat the process of configuring an initial node, node duplication, and subsequent update, for the CPU and Temperature nodes, for each device in the panel.

CPU Node Configuration

  • We use the Data > Prefix to identify what the node is presenting
  • Uncheck Appearance > Include Name as we are going to use the node position to identify the entity
  • Apply coloring rules to highlight threshold values
  • The Drilldown will be a focused CPU report:
    • Type = absolute
    • Run the report from the Console, filtered to the specific device, then copy the report URL
    • Paste the URL into the Drilldown > URL
    • Locate the device filter in the report URL (device=some_device) and replace the value with the label variable (${__label}) – this will allow us to duplicate the node for other devices without needing to update the drilldown URL
  • Duplicate, update, position for each device

Temperature Node Configuration

  • We use the Data > Prefix to identify what the node is presenting
  • Uncheck Appearance > Include Name as we are going to use the node position to identify the entity
  • Apply coloring rules to highlight threshold values
  • The Drilldown will be a focused Temperature report:
    • Type = absolute
    • Run the report from the Console, filtered to the specific device, then copy the report URL
    • Paste the URL into the Drilldown > URL
    • Locate the device filter in the report URL (device=some_device) and replace the value with the label variable (${__label}) – this will allow us to duplicate the node for other devices without needing to update the drilldown URL
  • Duplicate, update, position for each device


Link Configuration

Configure a single Interface Utilization node, then duplicate the link, updating the Data > Entity and Data > Field, and reposition as needed to populate the panel.

Once a single link is configured, we can duplicate the configuration to create additional links, speeding the process of populating the image map. We need to update:

  • Data > Entity
  • Data > Field – we are providing links for both Rx and Tx values
  • Label positioning may need to be adjusted for each link to improve in data legibility within the panel

When positioning links, the link ends will snap to attachment points on the nodes (attachment points can hold any number of links), this ‘snapping’ behavior can be overridden by holding the Alt key while positioning the link.

While in Edit Mode:

  • Drag a link handle to re-path the link
  • Left-click a mid-point to convert it to a vertex (creating new midpoints)
  • Right-click to delete a handle, simplifying the link
