The CWM Statistic Collection Manager (SCM) desktop application enables you to control and manage statistics collection. The SCM GUI is launched from the CWM desktop. The SCM server provides the statistics applicable to the different cards and nodes.
Primary/Secondary/Tertiary SCM GUIs provide distributed collection and statistics collection redundancy. Distributed collection means that you can distribute statistics collection from all switch nodes to different SCM collection servers.
SCM redundancy means that the secondary and tertiary SCM collection servers still continue to collect statistics when the primary SCM collection server is not reachable or completely shut down.
Refer to the CWM Release Notes, Release 10.3 for instructions on configuring Primary/Secondary/Tertiary SCM collection servers.
Launch the SCM GUI by clicking on the SCM icon on the main CWM desktop. Figure 8-1 shows the first window displayed after you launch the SCM. This window shows the SCM root in the network navigator panel on the left side, and the Log and Monitor panels of the SCM root on the right. The Node tab sits next to the SCM tab, but is out of view until it is selected.
The SCM view provides a hierarchical representation of the SCM collection servers. The workstations on which the SCM server is installed are displayed beneath the SCM root object. The nodes being managed by the SCM server are displayed beneath it.
While navigating the SCM view of the network, you can expand objects that are designated as container objects. The Monitor panel uses the following identifiers to collect statistical information: Node, Interval, Current Hour Success, Current Hour Failure, Last Hour Success, Last Hour Failure, and Status. Figure 8-2 shows an expanded view of the SCM view and the Monitor panel on the right.
Figure 8-2 shows an expanded view of the SCM view and the Log panel on the right. The Log panel displays logging information for the network, including File Name, Status, Request Time, and Completion Time. This information can be filtered using the navigator panel. When you select a collection server, the selected logs for the nodes managed by that server are displayed.
The node view also provides a hierarchical view of network elements. The node panel enables you to do the following operations:
Figure 8-3 shows an expanded node view of the SCM GUI.
Statistics collection is enabled by first selecting a node in the SCM root.
In the Network Navigator panel, in SCM mode, select
Select Options, then Configuration Parameters. The Configuration Parameters window appears, enabling the user to input the desired parameters.
Once the parameters have been set, click Apply, then OK.
After parameters have been set, right click to choose one of the following options:
The options above are also provided via the Options menu, as shown in Figure 8-3. After selecting an object, select Edit Current Collection Parameters to provide parameters specific to that object.
 |
Note The Start Collection option is not enabled unless statistics have been enabled for a network element. |
After you select an object and the Edit Current Collection Parameters, the SCM GUI provides three windows to guide you through the statistics collection enabling process. The Statistics Enable Dialog, Statistics Enable Dialog with Selected Statistics, and the Statistics Collection Parameters Dialog.
The SCM GUI first displays the Statistic Enable Dialog. The Statistic Enable Dialog lists all statistics that can be collected for the object you selected in the left pane.
Select the statistics you would like to collect for this object and click on the single-line arrow to designate these statistics as selected. To select all available statistics, click on the two-lined arrow. The two-lined arrow is the only option enabled until you select a specific statistic or group of statistics. The selected statistics are displayed in the panel on the right, as shown in Figure 8-5.
After selecting the statistics you want to collect, click Next to display the next screen of the Statistic Enable Dialog.
The next window in the Statistic Enable Dialog enables you to configure collection parameters. Figure 8-6 shows the Statistic collection parameters dialog.
The parameters that can be motified are described in Table 8-1.
| Parameter | Description |
|---|---|
Collection Period | Specify the interval value (in minutes) where statistics are gathered from the network. The collection period refers to the time it takes to create a stats file. The file will include multiple buckets. The default is 15 minutes. |
Time-Out Period | Specify the time-out value (in minutes for TFTP GET requests. Increase this value on busy networks. Busy networks should be configured for a high value. The default is 120 minutes. |
Bucket Interval | Specify the Bucket Interval Period value (in minutes) to be kept for the single bucket on the node. The default is 15 minutes.
|
Number of Retries | Specify the number of retries the child process makes in attempting to get files from the network. The default is 3 retries. |
Peak Statistics Enable | Specify peak statistics values on network by selecting No or Yes. The peak value represents the maximum value of buckets. The default is No. |
Use as a default template | You have the option to use this as a default template by selecting No or Yes. Yes is the default. |
The final window in the Statistic Enable Dialog allows collection server redundancy configuration (Figure 8-7.)
After you have configured and enabled Statistic Collection, you can begin to collect statistics. Network elements have an additional notation if they have been configured to collect or if they have been enabled. This notation appears on the far right side of the component label. The following notations are used:
To start collecting statistics, select an object that indicates statistics are enabled, then select the Options menu (or right click). The Start Collection option is now enabled, as shown in Figure 8-9.
To stop collecting statistics, select an object that indicates statistics are being collected, then select the Options menu (or right click), and select the Stop Collection option. The Stop Collection option is enabled, as shown in Figure 8-10.
Statistics are used to show network performance. Raw data can be used for monitoring nodes in your network, and for customer billing purposes. The Wingz Reports application provides statistics collection reporting.
