opCharts introduces a powerful new feature known as Metrics Metric Links. This feature enhances the visualization capabilities in topological, geographical, or network maps. It enables the establishment of a custom metric defining link weight and color. A common use-case for this might be defining the Signal-to-Noise Ratio (SNR) for a radio link between two distinct towers.
The Metrics Metric Links utilize the NMIS status system to derive their values, providing flexibility in defining what constitutes a good link versus a bad link. For detailed guidance on how to set this up, please refer to the guide on Creating Thresholds with NMIS Modelling.
Metrics Metric Links are compatible with all map types.
Adding a Metric Link
You can find the metric link Add Metric Link button next to the Add Interface Link button.
Adding a Metrics Metric Link:
Locate the Metrics Metric Link button situated next to the Add Interface Link button.
Metrics Metric Links function similarly to Interface Links. The key difference is that Metrics Metric Links allow the usage of any resource with a threshold to calculate the metricsMetric, instead of only interface data.
Choose the desired node. The resources (inventory) for the selected node will appear.
Next, choose the index for the resource.
If a threshold exists for the node, resource, and index, the status field will be auto-populated.
Lastly, select the link destination and save your changes.
The link between the two nodes will now utilize the status document's level to display the overall status, coloring colouring the link accordingly. The link's weight will be calculated based on the value.
Line Weight
| Level Range | Weight |
|---|---|
| Level < 5 | 2 |
| 5 <= Level < 10 | 3 |
| 10 <= Level < 20 | 4 |
| 20 <= Level < 40 | 5 |
| 40 <= Level < 60 | 6 |
| 60 <= Level < 80 | 8 |
| 80 <= Level | 10 |
Line Colour
| Status | Color Code |
|---|---|
| "reachable", "normal", "up" | #5cb85c |
| "degraded", "error", "minor", "warning" | #FFD700 |
| "unreachable", "major", "critical", "fatal", "down" | #d9534f |
| Others / Null | #999 |
Metric Link Resource Views
Another powerful aspect of the Metrics Metric Links feature in opCharts is the ability to configure custom resource panels, complete with tables and charts.
