Monitor Performance

This chapter describes the Performance Monitoring (PM) parameters used in Cisco NCS 2000 SVO and its related tasks.


Note


We recommend that you use either single EPNM session in standalone mode or EPNM with two servers in high availability mode. A single PM monitoring session is recommended either through EPNM, TL1, or SNMP.


Threshold Performance Monitoring

Thresholds are used to set error levels for each PM parameter.

During the accumulation cycle, if the current value of a PM parameter reaches or exceeds its corresponding threshold value, the PM details are highlighted with NA or with a change of color for the bucket. When a threshold is crossed, the node continues to count the errors during a given accumulation period. If zero is entered as the threshold value, generation of TCAs is disabled but performance monitoring continues. PM parameters are used by service providers to gather, store, set thresholds, and report performance data for early detection of problems.

From 12.3.1 onwards, TCA is supported on the NCS 2002 chassis.

Performance Monitoring

The Performance tab displays the PM parameters.

Performance Monitoring Tab

The Performance Monitoring tab consists of:

  • The Refresh icon manually refreshes the PM parameter values on the table.

  • The Auto-Refresh drop-down list automatically refreshes the PM parameter values on the table based on the selected time interval. The auto-refresh can be set for several intervals ranging from 15 seconds to 5 minutes.

  • The Interval drop-down list helps the user set a time interval at which the data would be split to be shown in the table. The two interval options that the user can choose to display the data are 15 minutes or one day.

  • The Interface Type drop-down list helps the user choose the interface type of the card. The options available are based on the selected card.

  • The Interface drop-down list helps the user choose the port of the card. The options available are based on the selected card.

  • The Direction drop-down list helps the user choose the direction of path. The user can choose from one of two options: nearEnd and farEnd.

  • The Clear PM button sets the PM parameter values on the card to zero. All counters on the card are cleared.

Interface Types

You have one of five options to choose from the interface type drop-down list: EthernetCsmacd, optical channel, OTNOdu, OTNOtu, and OpticalTransport.

Optics PM

The Optics PM tab lists the optics PM parameters for the SVO card.

Table 11. Optics PM Parameters

Optics PM Parameters

Definition

Laser Bias ( %)

Laser Bias (Laser Bias) is the percentage of laser bias optical during the PM time interval.

Rx Power (dBm)

Receive Power (Rx Pwer dBm) is the received optical power during the PM time interval.

Tx Power (dBm)

Transmit Power (Tx Power dBm) is the transmitted optical power during the PM time interval.

Sensor Data PM

A temperature sensor helps the user manage the system and diagnoses malfunctions. The temperature is measured in degrees of Celsius, and it can be negative. There are several temperature sensors available in the device. The device raises an interrupt when the temperature exceeds a certain threshold.

View PM Parameters

Use this task to view the current and historical PM counts of a card.

Before you begin

Procedure


Step 1

Click the Performance > Performance Monitoring tabs.

You can view the parameter names in the Parameter column and the corresponding PM values in the Current Reading and Prev-n (previous) columns.

Step 2

Select the Interval, Interface Type, Interface, and Direction from their respective drop-down lists.

Note

 
The options available are based on the card that is selected.

Step 3

Click Refresh.

The values are displayed in the table. If a complete count for the specified interval is not possible, the value appears against a yellow background. An incomplete or incorrect count can be caused by monitoring for less than the specified interval after the counter starts, replacing a card, resetting a card, or changing port service states. When the problem is corrected, the subsequent specified interval appears against a white background.

Step 4

(Optional) If you want to set an auto-refresh interval, select a value from the Auto Refresh drop-down list.

Depending on the selected autorefresh interval, the displayed PM counts automatically update when each refresh interval completes. When the autorefresh interval is set, the Refresh button is automatically disabled. If the autorefresh interval is set to None, the PM counts that appear are not updated unless you click Refresh.

Step 5

(Optional) To clear the current reading values, click Clear PM.

A confirmation message is displayed. Click Confirm to proceed.


View Live Data

The Live Data tab displays the instantaneous PM parameters for a card. These details can be used for troubleshooting. Use this task to view the instantaneous PM counts of a card.

Before you begin

Procedure


Step 1

Click the Maintenance > Live Data tabs.

You can view the parameter names in the Parameter column and the corresponding PM values in the Current Reading column.

Step 2

Select the Interface Type and Interface from their respective drop-down lists.

Note

 
The options available are based on the card that is selected.

The values are displayed in the table.

Step 3

Click Refresh to see the latest PM counts.

Step 4

(Optional) If you want to set an autorefresh interval, select a value from the Auto Refresh drop-down list.

Depending on the selected autorefresh interval, the displayed PM counts automatically update when each refresh interval completes. When the autorefresh interval is set, the Refresh button is automatically disabled. If the autorefresh interval is set to None, the PM counts that appear are not updated unless you click Refresh.

Export PM Data of SVO Card

Table 12. Feature History

Feature Name

Release Information

Feature Description

Export PM Data for SVO Card

Cisco NCS 2000 Release 12.3.1

From this release onwards, you can download the complete PM data for an SVO card through the SVO Web User Interface. This data can be used offline for device monitoring. The downloaded data is in an Excel format and is collated for the past 15 minutes and 1-day time duration.

This feature eliminates the need for individually accessing data for each PM parameter separately.

Export PM Data of SVO Card

Use this task to export the complete PM data for the SVO card. The PM data will be downloaded as an Excel sheet in your system after performing the following steps.

Before you begin

Procedure


Step 1

Click the Performance > Performance Monitoring tabs.

Step 2

Click Export to Excel with nested data.

The Excel sheet contains complete PM data for all the ports and interface type showing current and previous readings for the SVO card.

Note

 

The downloaded Excel sheet contains PM data for 15 minutes and 1-day interval.
