Monitor Performance

Performance monitoring (PM) parameters are used by service providers to gather, store, set thresholds for, and report performance data for early detection of network issues. You can configure and retrieve PM counters for the various controllers in flex-bin, 30-second, 15-minute, or 24-hour intervals. These parameters simplify troubleshooting operations and enhance data that can be collected directly from the equipment.

Monitor Performance

You can set and retrieve PM counters for the OTS, OTS-OCH, OSC, DFB, OCH, and OMS controllers for various intervals.

The OCH and OMS controllers are created when the Mux/Demux panel and breakout panels are powered up using the USB 2.0 connection from the NCS 1010 EITU card. You can only view the current and historical PM parameters for the panels. You cannot configure the PM parameters for these controllers.

This table lists the PM parameters, their descriptions, and precision levels.

Release Information

Feature Description

Improved Performance Monitoring

Cisco IOS XR Release 7.11.1

NCS 1010 now measures the power values of Photo Diodes (PDs) at various measurement points at a faster refresh rate to improve the node performance monitoring. With the upgraded FPDs, the refresh rate has reduced from 250 ms to 50 ms. This faster refresh rate applies to all the NCS 1010 PIDs for the following line card FPDs:

  • ILA

  • OLT

  • Raman-1

  • Raman-2

NCS 1010 measures the power values of Photo Diodes (PDs) at various measurement points to provide values for PM parameters. The measured values are refreshed at a defined rate for the latest values.

From Release 7.11.1, the rate at which the values of specific PDs are refreshed is reduced from 250 ms to 50 ms. This faster refresh rate is applicable to all the NCS 1010 OLT and ILA PIDs.

The following table provides the list of photo diodes that support the new refresh rate of 50 ms.

Feature Description

Threshold Crossing Alert (TCA) for Span Loss

Cisco IOS XR Release 7.11.1

You can now activate TCA reporting and set specific minimum and maximum threshold values for both Tx and Rx span loss across all time intervals.

This enhancement provides prompt notifications for deviations from normal span loss values, which can be viewed using the show alarms brief system active command.

To implement this feature, two new parameters slr-cl and slt-cl have been introduced for the pm command.

Additionally, the output of the show controllers ots R/S/I/P pm command now captures both the actual and configured threshold values for span loss.

Feature Description

PM History Persistence

Cisco IOS XR Release 7.11.1

PM history parameters for Optics, Ethernet, and coherent DSP controllers are now retained even after the occurrence of an operation disruptive event like:

  • Various reloads

  • Power cycle

  • System upgrade

This functionality maintains prolonged access to performance history for extended device health monitoring and assessment

Examples

The following example enables the maximum and minimum Threshold Crossing Alert (TCA) reporting on the OTS controller for a 15 minute interval on a C+L band network. The sample also configures the maximum and minimum Rx span loss threshold to 36db and 33db respectively. These values are compared against the current maximum span loss value to determine if a TCA should be generated.

RP/O/RPO/CPUO:ios(config)#controller pts 0/0/0/0 pm 15-min ots report slr-cl max-tca enable

RP/0/RP0/CPU0:ios(config)#commit
RP/0/RP0/CPU0:ios(config)#end
The following example shows the TOT-SPAN-LOSS-TX-CL-MAX alert is triggered when the current TX span loss value exceeds the maximum TX span loss threshold:
RP/0/RP0/CPU0:P1D_DT_04#show alarms brief system conditions | include SPAN

The following example sets the reporting status to maximum TCA for the eagn parameter of the OTS controller for a 15-minute interval. 

RP/0/RP0/CPU0:ios#config
RP/0/RP0/CPU0:ios(config)#controller ots 0/0/0/0 pm 15-min ots report eagn max-tca enable
RP/0/RP0/CPU0:ios(config)#commit
RP/0/RP0/CPU0:ios(config)#end

The following example configures the maximum threshold for the eagn parameter of the OTS controller to 20 dB.


Note

The OTS controller commands accept PM parameter values in two decimal places. In this example, the eagn parameter is entered as 2000 to configure the eagn parameter to 20 dB. 

RP/0/RP0/CPU0:ios#config
RP/0/RP0/CPU0:ios(config)#controller ots 0/0/0/0 pm 15-min ots threshold eagn max 2000
RP/0/RP0/CPU0:ios(config)#commit
RP/0/RP0/CPU0:ios(config)#end

To view the current PM parameters on an OTS controller for a 15-minute interval, use the following command:

RP/0/RP0/CPU0:ios#show controllers ots 0/0/0/0 pm current 15-min optics 1

The following output shows the current PM parameters on an OTS controller for a 15-minute interval and highlights the maximum threshold set for the eagn parameter that is configured for 20 dB.

PM History Persistence

PM history parameters are retained even after a line card cold reload, line card warm reload, rack reload, RP reload, power cycle, or upgrade of the NCS 1010 chassis.


Note

PM history persistence is not supported on NCS1K4-QXP-K9.

After a software upgrade to the latest release, you can view the history performance monitoring parameters from the previous release. The PM history persistence is supported for 30-second, 15-minute, and 24-hour bucket types. After upgrade from Release 7.11.1 to a higher version, if new PM parameters are available in the new version, below error is displayed while fetching PM data. 

RP/0/RP0/CPU0:ios#show controllers hundredGigECtrlr 0/0/0/8 pm history 15-min ether 5
Tue Apr  5 22:05:56.750 UTC
pm_display_int_15min_ether_index: bag_decode failed ('bag' detected the 'fatal' condition 'An irresolvable version conflict prevented the specified bag from being decoded')

However, the following list describes the time that is required to fill all historical buckets of each bucket type, later while fetching PM historical data, no error appears.

  • For 30-second bucket type, 15 minutes is required to fill 30 historical buckets.

  • For 15-minute bucket type, 8 hours is required to fill 32 historical buckets.

  • For 24-hour bucket type, 24 hours is required to fill 7 historical bucket.

PM counters are updated continuously in current bucket for all bucket types (flex, 30-second, 15-minute, and 24-hour). After the timer expires for the respective bucket type, the current PM data is moved to the historical PM bucket. This process of moving PM data to the historical bucket is called Rollover. After rollover, you can access the current PM data as historical PM data.

In case of deletion or removal of the controller, the PM data is persistent for 3 hours. Unless the controller is brought up within 3 hours, the PM data is cleared because the controller is considered to be not in use.

Limitations

If NCS 1010 reload or software upgrade happens during the rollover time, one of the following scenarios occurs:

  • The complete PM bucket is missing and the next PM bucket is marked as Invalid.

  • PM bucket expiry message appears as follows:

    RP/0/RP0/CPU0:ios#show controllers hundredGigECtrlr 0/3/0/2 pm history 30-sec ether 29
Fri Apr  1 01:32:20.646 UTC
History data is empty, Verify at least one collection period is expired

  • PM bucket interval is marked as Invalid and counters are updated as zero.

  • PM bucket interval is marked as Invalid and counters are updated as nonzero.
