| Request_rate |
Rate of requests
to the NAS engine. |
Reqs/Sec

A high request
rate is an indicator of server overload. By comparing the request
rates across application servers, an operator can gauge the
effectiveness of load balancers (if any) that are in use. |
| Response_time |
Average response
time (in seconds) for requests serviced by this NAS engine. |
Secs |
An increase in
response time associated with one of the NAS engines can indicate a
problem with the specific engine alone. |
| Pct_threads_utilized |
The percentage of
threads of this engine that are in active use. |
Percent
|
A value of close
to 100% is indicative of a bottleneck with a specific engine. |
| Data_xmit_rate |
Rate at which the
data is transferred by the engine in response to the incoming requests. |
KB/Sec
|
A sudden change
in data transmit rate can be indicative of a change in the
characteristics of key applications hosted on the engine. |
| Data_recvd_rate |
Rate at which the
data is received by the engine. |
KB/Sec
|
A sudden increase
or decrease in data rate to the engine is indicative of either an
increase or decrease in popularity of applications hosted on the NAS
engine under consideration. |
