Prerequisite: Set monitoring points as endpoints only works if the source and destination monitoring points can resolve each other by hostname. If they can’t, you will see a black overlay on your path performance charts because the monitoring point cannot connect to the target.
If you select multiple monitoring points in Step 1 of the path setup wizard, you can make those monitoring points the end points. This feature only works if the source and destination monitoring points can resolve each other by hostname. If they can’t, you will see a black overlay on your path performance charts because the monitoring point cannot connect to the target.
If you meet that prerequisite, then in this step you can interconnect monitoring points using a graphical interface to quickly set up multiple paths. You have two choices for network topology: ‘mesh’ and ‘hub-and-spoke’. To illustrate the difference let’s suppose you select four monitoring points in Step 1:
- You’ll get at least one path from each monitoring point to every other monitoring point.
- Single-ended gets you six paths because every monitoring point is either a source or a destination. You might be expecting twelve paths for a full-mesh—A to B and B to A, for every monitoring point—but if you want monitoring in both directions, you should select ‘dual-ended’.
- Dual-ended gets you six paths just like single-source. You don’t need 12 paths for a full mesh because each path monitors in both directions; it doesn’t matter which monitoring point is the source because the monitoring method is the same in both directions.
- Single and dual-ended gets you six single-ended and six dual-ended.
- This option chooses one monitoring point—the first one, alphabetically—to be the source, and all other monitoring points are targets. You can change the hub monitoring point from an additional drop-down. Click a path to reveal ‘remove path’ and ‘change direction’ options.
