Configuring SNMP Alarms for Rate Limiting

 appliances such as the NetScaler MPX 10500, 12500, and 15500 are
rate limited. The maximum throughput (Mbps) and packets per second (PPS) are
determined by the license purchased for the appliance. For rate-limited platforms, you
can configure SNMP traps to send notifications when throughput and PPS approach their
limits and when they return to normal.
Throughput and PPS are monitored every seven seconds. You can configure traps with
high-threshold and normal-threshold values, which are expressed as a percentage of
the licensed limits. The appliance then generates a trap when throughput or PPS
exceeds the high threshold, and a second trap when the monitored parameter falls to
the normal threshold. In addition to sending the traps to the configured destination
device, the NetScaler logs the events associated with the traps in the /var/log/
ns.log file as EVENT ALERTSTARTED and EVENT ALERTENDED.
Exceeding the throughput limit can result in packet loss. You can configure SNMP
alarms to report packet loss.
For more information about SNMP alarms and traps, see 
 on page 48.
Configuring an SNMP Alarm for Throughput or PPS
To monitor both throughput and PPS, you must configure separate alarms.
