Measurement
Unit |
Interpretation |
| New_requests |
The number of new HTTP requests to the netscaler device in the last
measurement period. |
Number |
This is an indicator of workload on the netscaler device. |
| New_http10_requests |
The number of new HTTP v 1.0 requests to the netscaler device in the last
measurement period |
Number |
Since HTTP 1.0
connections are not capable of providing information about the client's
ability to accept compressed data, which is one of the features of the
Netscaler devices, it is important to be able to monitor the number of HTTP 1.0
connections relative to the the total connections. |
| Incomplete_headers |
The number of incomplete HTTP headers received in the last measurement period with
incomplete headers |
Number |
The Netscaler performs content filtering by inspecting every incoming request according to user-configured rules, which are based on HTTP headers. If these headers are incomplete, the Netscaler would not be able to interpret the rules correctly, thus exposing the server to potential attacks. A high value of this measure is hence, undesirable; the reasons for the same should be investigated and the root-cause should be promptly addressed. |
| Incomplete_requests |
The number of HTTP requests received in the last measurement period |
Number |
|
| Incomplete_responses |
The number of incomplete HTTP responses from the Netscaler device during the last measurement period |
Number |
This value should typically be small under normal
operation. |
| Pipelined_requests |
The number of pipelined requests since the last measurement period |
Number |
|
| Server_busy_errors |
The number of HTTP requests for which server busy errors were sent during the last measurement period. |
Number |
This value should be close to 0. |
| Http_gets |
The number of HTTP GETs received during the last measurement period |
Number |
By analyzing HTTP GET and POST requests and filtering out known bad signatures, you can defend against HTTP-based attacks such as variants of Nimda and Code Red virus. |
| Http_posts |
The number of HTTP POSTs received during the last measurement period
SYN packets. |
Number |
| New_responses |
The number of new HTTP responses generated from the Netscaler device during the last
measurement period |
Number |
Compare the value of new requests and responses. These values
should be close to each other. A significant deviation may indicate a bottleneck or
malfuntioning of the Netscaler device. |
| New_http10_responses |
The number of new HTTP v 1.0 responses sent back during the last measurement period |
Number |
