To analyze and resolve any faults associated with optical
channel data units (ODUs) of OTN ports, it is essential to view the
diagnostic data, warnings, and alarms for transport performance monitoring.
The different types of parameters related to performance monitoring
that are retrieved from the ODUs enable you to ensure service availability
and verify or monitor individual services and the service network
performance.
The performance monitoring capability in Connectivity Services
Director displays information about the health of your network and
changing conditions of the OTUs of OTN ports. Use this diagnosis and
detection mechanism to identify problems with the equipment, pinpoint
security attacks, or to analyze trends and categories of errors. This
feature includes fault-monitoring details in the dashboard, in monitoring
pages, and on a dedicated page that displays alarms, events, and system
log messages that are generated. Performance monitoring parameters
can be viewed in both chart and statistical formats. These charts
and statistical details provide essential and cohesive information
about system conditions, any discrepancies and malfunctioning, and
protocols or components that need to be examined and debugged for
better efficiency and working capacity. You can assess the performance
of your network, not only at a point in time, but also over a period
of time. This feature enables you to determine trending and network-health
parameters; for example, whether service-level agreements (SLAs) have
been violated.
To view performance monitoring details of ODUs:
- From the Junos Space user interface, click the Build icon on the Connectivity Services Director banner.
The workspaces that are applicable to Build mode are displayed
on the Tasks pane.

(–) is displayed that denotes that an alarm for threshold-exceed
is not configured or a check mark is displayed and grayed out that
indicates that the TCA for the particular attribute is configured.

Select one of the following options from the drop-down
menu:
Select View Chart or the graphical icon (elliptical
curve symbol) to display the chart of performance monitoring statistical
metrics. A line graph is displayed with date and time along the horizontal
axis and the parameter along the vertical axis. A color-coding format
is used to display the different lines, and legends reference the
parameter names corresponding to the lines displayed. Mouse over
the points in the line graph to expand and show the value of the performance
monitoring counters at a particular time.
Select View Grid to switch over to the tabular
format of display of performance monitoring statistics.
The records are displayed in tabular format. A serial number
of the count of entries, the day, month, and year at which the entry
was collected, and the time at which the entry was collected are displayed.
The timestamp is the UTC time in the database that is mapped to the
local time zone of the client computer.
Select Save Chart, when you view the performance
monitoring statistics in graphical format, to save the graph to a
Microsoft Excel file, as a .png image. Click the pin icon on the upper-left
