Monitoring SCE Platform Utilization
Service Loss
Service Loss is an event which occurs when the SCE platform does not provide the processing it was
expected to perform for any transaction in the network. This can occur due to either CPU or Flows
shortage.
There are two different situations which can result with service loss in the SCE platform:
•
•
Service loss is defined as the ratio of the number of packets that did not receive service as expected to
the total number of packets that were processed by the SCE platform.
Monitoring Service Loss
•
It is expected that the SCE platform user will define timeslots in which this variable is monitored (reset
it between timeslots).
Note that the units for this variable are 0.001% and the information is rounded down.

Temporary – This might occur when some network pattern which is short in its nature occurred and
caused the SCE platform to exhaust some of it resources temporarily. An example could be a DDoS
attack that the SCE platform could not detect and filter.
This is usually measured in seconds.
Permanent – In cases where the SCE platform is installed in locations where the network traffic does
not match its capacity and performance envelopes, permanent service loss can occur.
This is measured in hours.
