PM General Information

PM Statistics 1 Day – 2 Bins, current & previous day

15 Minute – 33 Bins, current, 32 history (indexes 1~32) – accommodates 8 hours of history of 15 minute bins

Rollover counts – available via SNMP only

15 minute intervals are aligned to the quarter hour. They end at :00, :15, :30 and :45

1 day intervals are aligned to the day. They end at midnight.

History counts are managed in a circular fashion with the oldest bin being overwritten at the end of an interval when a current bin transitions to a history bin.

PM data does not survive reboots

A bin is marked suspect if duration of the collection period is off the expected duration by more than +/- 10 seconds. Link down/LOS will also result in a bin being marked suspect. Designated by an asterisk to the left of the time in the GUI.


Performance monitoring

Performance Monitoring enables in-service, non-intrusive system monitoring to aid in isolating and diagnosing issues that may occur during operation.

Selecting the performance monitoring application allows the user to view performance counts, view and edit threshold settings and initialize registers


Performance monitoring

To view performance monitoring stats, simply click on the entity in the selection tree;

From within this window you can view 15 minute and 1 day data bins, as well as threshold settings


Performance monitoring (GE206/GE206F)

Summary Window - Displays current TX/RX PM stats like a test set. Automatic refresh range is 5 to 60 seconds.


PM File Export

To export performance monitoring stats click on the “Export” button

When a PM Export operation is requested by the GUI the system shall automatically embed the name of the Entity ID and date in the filename


When exporting a PM file, the system includes

Description field which expands each MONTYPE acronym into a reasonable text string

Direction field which identifies the direction (TX or RX)

Location field which identifies the location (Near End of Far End)

Ethernet PMs Network Port

The Network port supports:

RX Direction:

RMON Etherstats,

ABR-RX,

L2CPFD and L2CPFP,

LOOKUPFAILS

TX Direction:

RMON Etherstats,

ABR-TX


Unavailable Seconds

Unavailable Seconds (UAS) on Ethernet ports and EVCs.

Used by Network/Service Management Systems to compute port-based and VID-based service availability

For Ports this parameter counts up if service affecting defects are reported on link level, SFP, EFM-OAM or CFM.

For EVCs UAS counts up if the underlying port is unavailable or service affecting conditions are reported by CFM.


Optical PMs

All interfaces that are configured with an SFP support optical PMs

Note that not all SFPs support the digital diagnostic monitoring interface (DDMI) which provides access to the following optical performance parameters.


LBC Laser Bias Current RX The laser bias current in mA (1 to 131 mA)

OPR Optical Power Receive RX The receive optical power in dBm (-76 to +16 dBm).

OPT Optical Power Transmit TX The transmit optical power in dBm (-76 to +16 dBm).


Threshold Crossing Alerts

User provisionable threshold values are supported for all Performance Monitoring counts and ESA probe statistics.

A separate threshold value is available for each bin interval (e.g. 15-minute and 1-day for PM)

When the PM count exceeds the provisioned threshold value, a Threshold Crossing Alert (TCA) is generated. A value threshold of 0 disables TCA generation. For OPR/OPT: -80 disables TCAs generation. TCA generated if measured value

differs from configured threshold by +/- 4 dBm

The TCA is a “transient” condition – the TCA represents the crossing of the threshold, not the fact that the count is above the threshold. As a result, TCA‟s are not explicitly cleared or visible via “show conditions”.

When a TCA is generated, an event is logged in the Alarm Log (unless the admin state of the entity precludes this) and an SNMP trap is generated, if one or more trap handlers are defined.

More than one TCA may be generated for a single count in an interval. This can happen if the count is initialized to 0 and crosses the threshold value a second time in the same interval.


TCA configuration

Right clicking on an entity and selecting “edit thresholds” opens the threshold configuration window, allowing the user to configure 15 minute and 1 day thresholds;

Note – setting a threshold to “0” disables threshold monitoring for that parameter
