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.

Performance Monitoring

The Performance tab displays the PM parameters.

Current Table

The Current PM table lists the parameters of the functioning cards with their current values. The table provides options to change the statistical values displayed.

History Table

The History PM table lists the history of the parameters of the functioning cards with their current and previous values. The table provides options to change the statistical values displayed.

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.

Definition

View PM Parameters

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

Before you begin

Procedure

Step 1

Perform 1.a to view current PMs or 1.b to view historical PMs.

  1. Click the Performance > Current PM tabs.

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

  2. Click the Performance > History PM 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.

Note 
The Clear PM button is not available in the History PM tab.
