Source Routing Monitor lets you view real-time inter-ring and intra-ring traffic statistics. For a single ring, Source Routing Monitor displays information about incoming and outgoing traffic, in addition to the current ring status and number. You can use this information to evaluate ring segment performance and throughput.
To begin working with Source Routing Monitor, you must be logged in to the network management console where TrafficDirector is installed, and have the TrafficDirector main window open. Select the Traffic radio button to display all the TrafficDirector applications that are related to the network traffic level. See Chapter 1, "Overview."
You can use Source Routing Monitor to see a detailed summary of traffic passing in and out of the ring, as well as traffic within the ring. To view a summary of ring traffic, take the following steps:
Step 1 Select a Token Ring agent from the TrafficDirector main window.
Step 2 Click the Src Route Monitor icon.
The TrafficDirector Source Routing Monitor application window opens (Figure 22-1).
At the top of the Source Routing Monitor display, just under the toolbar is the Ring Status bar with information about the ring number, and the status of the ring. The ring number refers to the ring being monitored by the agent you selected when you launched Source Routing Monitor. Status indicates the current operational mode of the ring being monitored by the agent you selected. When the ring is operational, "Normal Operation" is displayed to indicate that the ring is up and working properly.
Below the Ring Status bar is a list of statistics that show either per-second rates, or cumulative rates depending on the mode you select. To change modes, select Mode, then highlight the mode you want. Per-second mode updates Source Routing information on a per-second basis, or routing statistics for a period of one second. Cumulative mode shows the total accumulated real-time statistics for the ring.
Table 22-1 describes each of the statistics available in Source Routing Monitor.
