Viewing admission control data
The Admission Control report tracks admission control events (Connection Limit, CPU, MAPI, Memory, Service, and TCP limits) over a time period you specify. Use this report to monitor and diagnose admission control problems in your deployment before they occur.
If all appliances are 9.6 or later, you can view frequency of individual alarms.
Data is displayed in different colors. Data is only displayed if an event has occurred.
The Admission Control report contains a graph that summarize the activity.
Control
Description
Connection limit
Indicates the system connection limit has been reached. Additional connections are passed through unoptimized.
Service
Indicates that the number of connections receiving unoptimized service has exceeded the supported limit.
CPU
The appliance has entered admission control due to high CPU use. During this event, the appliance continues to optimize existing connections, but new connections are passed through without optimization. The alarm clears automatically when the CPU usage has decreased.
MAPI
The total number of MAPI optimized connections has exceeded the maximum admission control threshold. for the alarm to clear.
TCP
The appliance has entered admission control due to high TCP memory use. During this event, the appliance continues to optimize existing connections, but new connections are passed through without optimization. The alarm clears automatically when the TCP memory pressure has decreased.
Memory
The appliance has entered admission control due to memory consumption. The appliance is optimizing traffic beyond its rated capability and is unable to handle the amount of traffic passing through the WAN link. During this event, the appliance continues to optimize existing connections, but new connections are passed through without optimization. No other action is necessary; the alarm clears automatically when the traffic has decreased.
The Admission Control report contains this table of statistics that summarize the event activity.
Control
Description
Appliance
Displays the appliance name and IP address.
Appliance Model
Displays the appliance model.
Type of event
Displays the total number of events for the appliance according to the type of event (that is, admission control, TCP, memory, CPU, MAPI, connection limit, and service.
What this report tells you
The Admission Control report answers these questions:
•  Why aren’t my SteelHeads healthy and performing optimally?
•  How much traffic is a particular SteelHead optimizing?
•  How effective is a particular SteelHead at saving bandwidth?
•  How many connections could have been optimized if my SteelHead had not been in Admission Control?
The Riverbed system reports on performance for periods up to one month. Due to performance and disk space considerations, the display granularity decreases with time passed since the data was sampled.
