1) Filtering Metrics – displays all information relating to the operation of Filtering, Firewallling, NAT, and TTL
Translation. Usually there is too much information for one page, and the scroll bars on the right side need to
be used.
2) Interface Metrics
– displays detailed information about all operating network devices in the receiver. Usually
there is too much information for one page, and the scroll bars on the right side need to be used.
3) Multi Router Traffic Grapher (MRTG) Metrics
– displays key metrics provided by the other menus in graphic
form using the MRTG real time graphing tool.
4) Multicast Routing Metrics
– displays detailed metrics for all multicast streams, including number of packets
and bytes being output. This is very useful for debugging a receiver installation.
5) RF Metrics
– displays detailed metrics relating to the RF carrier and the DVB transport stream with all its
associated PIDs. There are two pages to this menu item:
a. RF Metrics
– this page provides essentially a copy of the RF Metrics that are captured at the bottom
of the screen, with two additions: the current AFC range (from the LNB Attributes) and Reed-
Solomon Uncorrected Packets (from 0 to 32767).
b. PID Metrics – this page provides information relating to the MPEG2 Transport Stream, and
specifically, data captured and output from specific PIDs being filtered and de-encapsulated from
MPE frames. MPE PID data is applicable to the net port.
6) System Health Metrics
– displays information relating to the operation of the internal components. At the
present time, metrics relating to the fan speed of the two internal fans, and the CPU surface temperature are
provided.
In all cases, the metrics that are displayed on a selected page can be automatically refreshed by setting the Metrics
Refresh Interval. This refresh interval is independent of the refresh interval for the RF Metrics Display Area at the
bottom of the Main page. The range for the Refresh Interval is 10 to 1000 seconds.
For remote site debugging, the RF Metrics can also be committed periodically to a log file using the RF Metrics
Logging Interval, so that the RF performance can be monitored over a period of time. The range for this interval is 1 to
60 minutes
The following Metrics subsections will provide sample screen captures of typical metrics pages, as well as any
additional details as required.
Filtering Metrics
Figure 2- 50 shows the complete display (scrolling from top to bottom) of the Filtering Metrics for the filtering tables (in
the order: Filtering/Firewall, NAT, and TTL). Since there is too much information to be displayed on one page, the
scroll bar on the right hand side must be used.
NOTE: In order
to see the RF
Metrics being
written to the
system log, you
must set the
Minimum Log
Level to ‘Debug’
or ‘Info’.
