Health Check Map
In Health Check Map, you can view all health check targets registered to an NMS manager on a single map. The map has a radial structure that starts from the manager as the root and extends through devices to health check targets. You can narrow the display scope by status, protocol, group, device, and search term. While Health Check Status shows time series metrics for a selected target, Health Check Map helps you find the target distribution and problem points across the entire manager on one screen.
Basic screen
The screen consists of the top filter bar, the left sidebar, and the map canvas on the right.
Top filter bar
| Item | Description |
|---|---|
| Time selection | Displays whether live refresh is enabled and the refresh time. When live is on, data is queried again every 60 seconds |
| Refresh | Queries data again immediately, regardless of the live interval. Disabled while a query is running |
| Select Manager | Selects the NMS manager to query |
| Status | Status filter. Multiple selection of Alive, Dead, and Inactive |
| Protocol | Protocol filter. Multiple selection of ALL, ICMP, and TCP |
| Reset filters | Clears all five filters at once: status, protocol, group, device, and search term. Disabled when no filter is active |
For the status and protocol filters, selecting nothing displays everything. When you select items, only the selected items remain, and the number of matches under the current conditions is displayed next to each item.
Filters, search terms, and the live setting are preserved as URL query parameters. Query conditions are retained when you go back, refresh, or share a link.
Sidebar
The sidebar consists of three tabs. You can adjust the sidebar width by dragging the divider next to the tabs.
| Item | Description |
|---|---|
| Device view | Device list. Selecting an item displays only that device |
| Group view | Group tree. Displays only the devices belonging to the checked groups. Devices that do not belong to a group hierarchy are grouped under Unassigned |
| Statistics | List of the top 30 health checks by Max RTT or Jitter |
-
You can sort the device view by Most Dead or Name.
-
When you select an item in the Statistics tab, only that health check remains on the map. Selecting the same item again clears the selection.
Map canvas
The map is displayed in a three-level structure: manager (root), device, and health check. If a node has an alias, its label shows the alias and host on two lines; otherwise, only the host is shown.
| Item | Description |
|---|---|
| Health check node color | Green for Alive, red for Dead, gray for Inactive |
| Node mouseover | Displays status, protocol, metrics, and details in a tooltip |
| Device node click | Turns the filter for that device on or off |
| Canvas search | Select the search icon in the upper right and enter a device or health check name. Nodes that do not match are dimmed |
| Map display settings | Select the settings icon in the upper right and use the Show group information switch to choose whether to display the group hierarchy |
| Zoom controls | Fit to screen, Zoom out, and Zoom in in the lower right |
| Minimap | Displays an overview of the entire map in the lower right |
When you turn on Show group information, the map changes from a radial layout to a left-to-right layout that reflects the group hierarchy.
Health check node tooltip
| Item | Description |
|---|---|
| Metrics | Avg RTT and Max RTT (ms), Loss (%), Jitter (ms) |
| Details | Alias, Target IP, FQDN, and whether the target is enabled |
| Measurement time | Last measurement time |
When you hover over a device node, the status distribution (Alive/Dead/Inactive) and protocol distribution (ICMP/TCP) of the health checks belonging to that device are displayed.
Managing health checks on the map
Right-click a node on the map to manage health checks directly.
-
Device node: Add health check
-
Health check node: Edit, Enable or Disable, Delete
When a task succeeds, the map data is queried again immediately. For nodes whose original health check cannot be found in the inventory, delete and edit are displayed as disabled.
Right after you add a health check, metrics may be empty because the first check has not run yet. Values are filled in after the next check interval.
