Cisco Prime Optical User Guide, 10.6

Viewing Performance Monitoring for an NE

To view PM data for an NE, you must first collect the data. To collect the PM data, you need to activate the PM service for your NE and then enable PM collection on that NE. The PM service can be activated either before or after the PM collection is enabled on the NE(s). The PM data is not available until both operations are completed and the first PM collection occurs.

Enabling Performance Monitoring

Performance monitoring is optional, but you must enable it if you want to monitor threshold alarms and performance parameters.

Performance monitoring can be enabled on NEs by using the device CLI. For information about using the CLI, see the relevant hardware documentation.

Note PM data collection is resource intensive in terms of CPU, disk space, and DCN utilization, so you should exercise proper planning and resource monitoring for PM data collection.

Understanding the PM Service Pane

Use the PM Service pane ( Administration > Control Panel ) to activate or deactivate global PM data collection and change NE PM data collection parameters. When you click Save to save your change, the change takes effect immediately.

Table 10-1 Field Descriptions for the PM Service Pane

Field	Description
PM Data Storage	PM data storage status. If set to Normal, all performance data collected is displayed in the PM data tables. If set to Optimized, performance data with all zero values and performance data with all invalid flags are not displayed and are not stored in the database.
Robust PM Collection Queue	Number of 15-minute and 1-day outstanding robust PM registers. Click Clear Robust PM Queue to clear the queue.
PM 15-Min Retrieval Fail Alarm	Enable or disable a retrieval fail alarm for 15-minute PM data. Check the Enable check box; then, enter the number of seconds between each retry, and enter the number of retries to attempt before the alarm is generated.
PM 1-Day Retrieval Fail Alarm	Enable or disable a retrieval fail alarm for 1-day PM data. Check the Enable check box; then, enter the number of minutes between each retry, and enter the number of retries to attempt before the alarm is generated.
Real-Time PM Performance Parameters	When a real-time PM session is running, it polls the NE for x number of attributes every 10 to 900 seconds. The data it returns is stored entirely in transient memory. Use the following fields to limit the scope of the real-time PM session: Maximum number of concurrent real-time PM sessions—Specify the maximum number of concurrent real-time PM sessions allowed per client. The range is from 1 to 5 sessions; the Cisco default is 5. Maximum number of polled real-time PM objects—Specify the maximum number of objects that can be polled in a single real-time PM session. The range is from 1 to 100 objects; the Cisco default is 100. Maximum number of rows held in cache—Specify the maximum number of rows that can be held in the real-time memory buffer per session. When this limit is reached, the oldest rows are removed from the buffer to make room for new rows. The range is from 100 to 5000 rows; the Cisco default is 1000. Note Depending on the PM table launch selection criteria, the number of rows displayed might be less than the maximum number of rows specified.

Understanding the Individual PM Service Panes

The PM Service properties pane ( Administration > Control Panel > PM Service ) displays information about the status of performance monitoring for the selected NE. You can also stop or start an individual PM service instance. The individual PM service panes are broken down by NE:

• ONS 15305
• CTC-Based PM Service Panes

– ONS 15310 CL/ONS 15310 MA/ONS 15327/ONS 15454/CPT 600/CPT 200

– ONS 15310 MA SDH/ONS 15454 SDH/CPT 600 SDH/CPT 200 SDH

– ONS 15600

– ONS 15600 SDH

– CRS

ONS 15305

The ONS 15305 PM Service pane displays ONS 15305 NE PM service information. Table 10-2 provides the descriptions.

CTC-Based PM Collection Parameters

Step 2 Right-click a Layer 3 link in the Network Map and choose Link PM Data from the right-click menu.

Managing Real-Time PM Data

Prime Optical supports the ability to launch a real-time PM report from the PM Query wizard or from a single row in a PM table. This feature allows you to examine the current value of a PM parameter in granularities finer than the standard 15-minute or 1-day interval. You can view and modify the polling interval for the real-time PM reporting session.

Note Real-time PM reporting applies only to CTC-based NEs.

The following real-time PM selection options are available:

• Polling—When selected, Prime Optical periodically polls the selected PM parameter(s) on the selected NE. The polling intervals are 10 to 900 seconds—For CTC-based NEs

Note You can specify the real-time polling interval in the Real-Time Polling dialog box. See Changing the Real-Time Polling Interval.

• Refresh—Allows you to start polling of real-time attributes if real-time polling is disabled in the Real-Time Polling dialog box.
• Baseline—When selected, the most recently collected data set is saved into a buffer. All new values are recalculated as they arrive based on the saved baseline values.

Note Not all values can be saved as a baseline. For example, null and string values cannot be saved as baseline values.

• Clear Baseline—Sets the baseline values to zero.
• Clear—Clears the current real-time PM buffer of all values.

Each 15-minute or 1-day PM table has a corresponding real-time PM table. However, not all of the fields in the historical PM tables are shown in the real-time PM tables. The first fields in real-time PM tables are:

• Alias ID—Alias name of the selected NE.
• Module Name—Module for which PM data is displayed.
• Physical Location—Slot and port number for which PM data is displayed.
• Interface—Interface name of the selected NE.
• Time Stamp—Time when the performance statistics were collected.
• Maintenance—Whether the NE was under maintenance when the performance data was collected.

The remaining fields are the actual real-time attributes being polled.

When a real-time PM session is running, it polls CTC-based NEs for x number of attributes every 10 to 900 seconds. The data it returns is stored entirely in transient memory. You can use the PM Service properties pane in the Control Panel window to limit the scope of the real-time PM session. See Understanding the PM Service Pane.

• To launch a real-time PM report from the PM Query wizard, see Using the PM Query by Category Wizard or PM Query by NE Model Wizard. In the NE Model Selection screen, click the Real-Time radio button.
• To launch a real-time PM report from a single row in a PM table, select a row and choose View > Launch Real-Time Performance Session (or click the Launch Real-Time Performance Session tool).
• To clear the real-time PM counters on the NE, choose View > Clear PM Counters on NE (or click the Clear PM Counters on NE tool).

Note Use the toolbar icons to manage the real-time display. See Icons and Menus Displayed in Prime Optical for an explanation of the icons.

Changing the Real-Time Polling Interval

By default, the real-time PM session polls the attributes every 10 seconds for CTC-based NEs. You can configure the polling interval from 10 to 900 seconds.

Step 1 Launch a real-time PM table.

Step 2 Choose View > Specify Real-Time Polling Interval (or click the Specify the Real-Time Polling Interval tool). The Real-Time Polling dialog box opens.

Step 3 In the Specify Real-Time Polling Interval field, enter a number from 10 to 900 seconds.

Step 4 Complete one of the following options:

• To save the change, click Apply .
• To save the most recently collected data set into a buffer, click Baseline . All new values are recalculated as they arrive based on the saved baseline values.
• To set the baseline values to zero, click Clear Baseline . This disables the baseline set.
• To discard changes and close the dialog box, click Cancel .

Enabling or Disabling Real-Time Polling

Step 1 Launch a real-time PM table.

Step 2 Choose View > Specify Real-Time Polling Interval (or click the Specify the Real-Time Polling Interval tool).

Step 3 To disable real-time polling, uncheck the Enable Real-Time Polling check box. To enable real-time polling, leave this check box checked. When automatic polling is enabled, you do not need to manually refresh the real-time PM table.

Step 4 Click Apply .

Filtering PM Data

Use the Filter dialog box ( File > Filter ) to filter data according to criteria that you select, and then display the results in a table. The following table provides descriptions.

Note The Filter dialog box is not available for real-time PM data.

Table 10-11 Field Descriptions for the PM Table Filter

Tab	Description
Time Stamp (also Time Period )	Filters PM data for a specified time period, ranging from the past hour to the past 6 months. Additionally, you can click the User Specified radio button to specify exact filter start and end times by date and hour. The time zone used can be GMT, an offset from GMT, or local time, depending on what you specified in the User Preferences dialog box.

Month—Click the month combo box or the single arrow (<, >) at the bottom of the calendar. Day—Click the day number on the calendar. The current date is shown in blue. If you want to filter events and the time period is not important, click No Time Specified .
NE ID (also Network Elements )	Filters PM data by NE. PM data will display for NEs in the Selected list. Use the Add and Remove buttons to select the NEs for which you want to display PM data.
Module Name (also Managed Entities ; not available for all NEs)	Filters PM data by module. PM data will display for modules in the Selected list. Use the Add and Remove buttons to select the modules for which you want to display PM data.
Physical Location	Filters PM data by rack, subrack (shelf), slot, subslot, card, or port. (Options depend on the type of NE selected.) Use the drop-down lists to choose the entity for which you want to display PM data. Note Physical location includes shelf, slot, and port information; for example, Shelf: 1, Slot: 14, Port: 0

Using PM Data Graphs

PM tables contain a Plot tab that allows you to plot historical or real-time PM data in a graphical view that is stored in the Prime Optical database. You can plot a maximum of three PM parameters at a time per graph. You can select a line or bar graph type and you can display multiple traces on the same set of axes for comparison. Prime Optical automatically scales the graph’s Y-axis to best show the values of the measured parameters. You can launch a graph of PM data for the following data types:

• One PM parameter on one board
• Multiple PM parameters on one board

Note Parameters must have similarly scaled ranges, such as errored seconds and severely errored seconds. For example, you cannot plot bit errored rate and errored seconds on the same graph. Instead, these parameters are plotted on separate graphs.

• One PM parameter on multiple boards

Note Boards must all support the selected PM parameter.

Complete the following steps to use PM data graphs:

Step 1 View PM data by PM category (see Using the PM Query by Category Wizard) or non-CTC-based NE Model (see PM Query by NE Model Wizard).

Step 2 From the PM table, select the row of the NE, port, or slot for which you want to view the PM data on a graph.

Step 3 Choose View > Plot (or click the Plot tool).

Note To plot the graph, you must choose View > Plot or click the Plot tool. If you simply click the Plot tab (without choosing View > Plot or clicking the Plot tool), the graph is not filled out.

In the Plot tab, the graph is displayed. The graph can plot a maximum of three PM parameters. The graph’s status bar displays the selection context in the following format:

Note Physical-location includes shelf, slot, and port information; for example, Shelf: 1, Slot: 14, Port: 0.

Step 4 Use the plot-specific toolbar buttons to manage the graphical display. Choose View > Zoom In , Zoom Out , or Fit in Window to adjust the zoom level. You can also click the Zoom In , Zoom Out , or Fit in Window tools.

Note If Prime Optical cannot complete samples retrieval in a certain time frame (for example, due to a temporary loss of communication), the PM graph interpolation will be traced from the last sample that was retrieved before the malfunction occurred to the first sample that was retrieved after normal behavior was restored.

Configuring a Graph

Use the Graph Parameters Selection dialog box to modify the parameters that are plotted in a graph.

Step 1 From the PM table, select the row for which you want to view the PM data on a graph.

Step 2 Choose View > Graph Configure (or click the Configure Graphing Parameters tool). The Graph Parameters Selection dialog box opens.

Step 3 For historical PM graphs, select the start and end times in the Time Panel area. Choose the date, hour, and minute from the corresponding drop-down lists.

Note Real-time PM graphs do not have a Time Panel area, because a time range does not apply to real-time data.

Step 4 In the Parameter Selection area, select the parameters from the Available Parameters list that you want to plot in the graph. You can generate a maximum of three graphs and each graph can plot a maximum of three parameters.

Step 5 Click the Add button that corresponds to the graph where the parameter will be plotted. Selected parameters are listed in the Selected Parameters: Graph number list.

Step 6 To remove parameters from the Selected Parameters: Graph number list, select parameters and click Remove .

Step 7 Click OK . The graph is displayed in the Plot tab. The status bar displays the module name, physical location, interface, date range, and time stamp range.

Step 8 You can adjust the zoom level for each graph. Click a graph and choose View > Zoom In , Zoom Out , or Fit in Window . You can also click the Zoom In , Zoom Out, or Fit in Window tools.

Step 9 You can normalize or restore the Y axes values in historical PM graphs. Choose View > Normalize Y Axes or Restore Y Axes (or click the Normalize Y Axes or Restore Y Axes tools). The Normalize option allows you to normalize axes values and compare data of the same type (for example, receive versus transmit packets). The Restore option restores axes values to the previous graph visualization.

Note The Normalize and Restore options do not apply to real-time PM graphs.

Printing a Graph

Step 1 After viewing PM data on a graph or configuring a graph, choose File > Print Graph (or click the Print Graph tool). The Print dialog box opens.

Step 2 Select your printer and configure the page setup options, as necessary.

Step 3 Click OK .

Note PM graphs might not print completely on some printers with the default page setup settings. In this case, you need to change the printer setup. To do this, click Properties in the Print dialog box. Click Advanced. Change the scaling to a value that prints the complete graph; for example, 10% or 20%. Click OK.

Understanding How Prime Optical Displays the Interface Field

Prime Optical displays the Interface field in PM tables as follows:

• ONS 15305

Prime Optical representation:

Interface-type #Interface-type-numberAUG4- AUG4-number /AUG1- AUG1-number /TUG3- TUG3-number /TUG2-TUG2-number / TU12- TU12-number

where:

– Interface-type is the affected interface object

– Interface-type-number is the interface number

– AUG4-number is the AUG4 number (applies to VC-4, VC3, and VC12)

– AUG1-number is the AUG1 number (applies to VC-4, VC3, and VC12)

– TUG3-number is the TUG3 number (applies only to VC3 and VC12 interfaces)

– TUG2-number is the TUG2 number (applies only to VC12 interfaces)

– TU12-number is the TU2 number (applies only to VC12 interfaces)

• SDH

Prime Optical representation:

Interface-type # VC4-number /VC3- VC3-number /TUG2- TUG2-number /VC12- VC12-number

where:

– Interface-type is the affected interface object (for example, VC4, VC4-2c, VC3, VC12, and so on)

– VC4-number is the VC4 number in that interface (applies only to VC4, VC3, and VC12 interfaces)

– VC3-number is the VC3 number in that VC4 (applies only to VC3 interfaces)

– TUG2-number is the TUG2 number in that VC3 (applies only to VC12 interfaces)

– VC12-number is the VC12 number in that TUG2 (applies only to VC12 interfaces)

For example, for alarms on a VC12 interface with VC4-number = 1, VC3-number = 2, TUG2-number = 1, and VC12-number = 2, Prime Optical displays VC12 #1/VC3-2/TUG2-1/VC12-2, where the first field is the affected interface and VC4 number (# VC4-number ). This example indicates that the alarm is on the VC12 interface with the VC4 number equal to 1 (VC12 #1).

• SONET

Prime Optical representation:

Interface-type # STS-number / VT-group-number - VT-number-in-group

where:

– Interface-type is the affected interface object (for example, STS1, STS3c, VT-1, and so on)

– STS-number is the STS number on that interface (applies only to STS and VT interfaces)

– VT-group-number is the VT group number for that STS number (applies only to VT interfaces)

– VT-number-in-group is the VT number in that VT group (applies only to VT interfaces)

For example:

– For a VT path-level alarm with STS-number = 1, VT-group-number = 2, and VT-number-in-group = 1, Prime Optical displays VT-1 #1/2-1, where the first field is the affected interface and STS number (# STS-number ). This example indicates that the alarm is a VT path-level alarm with STS-number = 1 (VT-1 #1).

– For an STS path-level alarm with STS-number = 1, Prime Optical displays STS3c #1, where the first field is the affected interface and STS number (# STS-number ). This example indicates that the alarm is an STS path-level alarm with STS-number = 1 (STS3c #1).
