The tools provided by ZfS to analyze your network performance have default settings. You can change the default settings of various views to display only the information you require.
The following sections provide information about how you can configure the ZfS tools to suit your networking environment:
You can configure the Stations view to display only the top 20 nodes or all nodes on the monitored segment. You can also choose the statistic based on which you want to display the top 20 nodes.
The following configuring options are available:
To display statistics for the top 20 nodes on a segment:
Packets out per second is the default statistic based on which top 20 nodes are displayed in the Stations view. To choose a different statistic based on which you want the top 20 nodes to be displayed, do either of the following:
The available statistics are described in the following table.
If you close the Stations view after changing the default settings, you will be prompted to save the changes made to the default settings. If you want the Stations view to be displayed based on the statistic you chose, you can save the setting. The next time you open ConsoleOne and launch the Stations view, you will be able to view the nodes on the monitored segment based on the statistic you specified.
You can change the default settings based on which the segment performance trends are displayed in the Segment Trends view.
The following configuration options are available:
To change the statistics based on which segment performance trend is displayed:
Click the Profile button in the Segment Trends view.
Select a profile from the Select Profile list.
The default profile will display a trend with statistical information of total packets, good packets, and error packets on the monitored segment.
If you choose not to use the profiles listed in the Select Profile list, you can select the required statistics from the Select Statistics list.
The statistics list lets you examine the Ethernet, FDDI, and token ring statistics described in the following table.
If you close the Segment Trends view after changing the default statistics based on which trend is displayed, you will be prompted to save the changes made to the default settings. If you want the segment performance trend to be displayed based on the profile or statistics you chose, you can save the settings that you define. The next time you open ConsoleOne and launch the Segment Trends view, you will be able to view the trend based on the profile or statistics you defined.
The segment performance trend is updated once every minute. You can set a different time scale based on which you want to update a graph. Select from the following time-scale options:
HINT: If you close the Segment Trends view after changing the default time-scale option based on which trend is displayed, you will be prompted to save the changes made to the default settings. If you do not want the trend to be updated in real time, you can save the time-scale setting you choose. The next time you open ConsoleOne and launch the Segment Trends view, the trend will be updated based on the time-scale option you selected.
You can configure the Segment Dashboard view to display or disable the top nodes graph. For details, see Viewing the Graph of the Top Nodes on a Monitored Segment. The top nodes graph is displayed in the lower portion of the Segment Dashboard view. Packets out per second is the default statistic based on which the graph is displayed. You can choose a different statistic based on which you want the graph to be displayed.
The following configuring options are available:
To display the top nodes graph in the Segment Dashboard view:
To display the top nodes graph based on a different statistic, do either of the following from the Segment Dashboard view:
The statistics are described in the following table.
IMPORTANT: Errors per minute, broadcasts per minute, and multicasts per minute are updated every 60 seconds rather than every 5 seconds.
ZfS provides statistics for each port on the switch. You can view port statistics and a list of nodes connected to each port using the Unified Port Traffic view. You can view Ethernet-specific statistics for Ethernet ports on a switch. Although statistics specific to FDDI and token ring ports will not be displayed with this version of ZfS, general port statistics are displayed for all ports on a switch regardless of the media type. For details, see Viewing Statistics for Ports in a Switch. You can choose to display only the selected statistics in the Unified Port Traffic view.
To select statistics to be displayed in the Unified Port Traffic view:
From the Unified Port Traffic view, click View > Settings.
Click the statistics from the Available Columns list > click Add.
The following table describes the general port statistics displayed for a port, regardless of the media type of the port.
The following table describes the Ethernet-specific statistics displayed for an Ethernet port in addition to the general port statistics listed above.
ZfS provides default settings to display a captured packet in the Trace Display window.
To change the default settings and display the trace differently:
Open the Trace Display window.
From the Trace Display menu, click View > Options.
Select how you want to display the decoded packet.
Select the level at which you want to display the initial highlight position.
Select the format in which you want to display the decoded packet.
ZfS provides default alarm threshold values for a segment. You can set threshold values for various error conditions on Ethernet, FDDI, and token ring segments to eliminate the need to constantly monitor the segments.
When a segment alarm is enabled, the RMON agent monitors the segment based on the alarm threshold settings. If the configured threshold value is exceeded, the RMON agent sends a trap to the management server, which forwards it to ConsoleOne.
You should change the default values for alarm thresholds as appropriate for your organization. You can determine the appropriate value by observing average and peak traffic levels on your network using the Segment Trends view. For details, see Analyzing Trend Data for a Segment. You can do this as a part of creating a baseline of typical segment activity on your network.
To set an alarm threshold for a segment:
Select a segment from ConsoleOne.
Click File > Properties > the Segment Alarms tab.
Select a segment statistic > click Edit.
Click Enable to enable the alarms set for the monitored segment.
When you click Enable, the text fields and the Default button will be enabled. However, if the default threshold values are not found, the Default button will not be enabled.
Enter the threshold value.
Specify the sampling time interval.
The RMON agent uses the sampling time interval to average the statistic to determine whether the alarm threshold was exceeded.
HINT: You can also use the Segment Dashboard view to define alarm threshold values for segment statistics. For details, see Defining Alarm Thresholds for Statistics Displayed in the Segment Dashboard View.
The following table describes the alarm statistics that ZfS tracks for Ethernet, FDDI, and token ring segments.
When you have set the appropriate threshold values for the segments in your network, you can use the Save As Default button on the Segment Alarms property page to save the values you defined as the default values. However, the default threshold values provided by ZfS will not be available once you apply the new values.
By default, the poll interval for refreshing the Monitor Nodes for Inactivity view is zero seconds. You can configure the poll interval based on which you want the view to be refreshed. The agent monitoring nodes on a monitored segment declares a node as inactive after verifying it for a specified period of time. You can change the time duration for the agent to verify the node before declaring it inactive.
The following configuring options are available:
You can modify the PollInterval parameter in the LSMPARAMETERS.PROPERTIES file to specify the poll interval for refreshing the Monitor Nodes for Inactivity view.
To specify a poll interval for refreshing the Monitor Nodes for Inactivity view:
When a selected node becomes inactive, the agent monitoring the node verifies the state of the node for one minute before declaring it inactive. You can modify the HostTimeOut parameter in the LSMPARAMETERS.PROPERTIES file to change the duration for the agent to verify the selected node before declaring it inactive. The agent verifies the inactive node for the specified period of time before declaring it inactive.
To change the duration for the agent to verify a node before declaring it inactive:
