Measures reported by ClusterHttpTest
A Web Cluster is a set of web servers to be accelerated. The DX appliance
listens for incoming web traffic to a specific Virtual IP address and port, distributes it over the target hosts (web servers) in the cluster. Typically all the web servers in a particular cluster serve identical
content; that is, each cluster usually represents a distinct website or property.
This test reports the HTTP statistics per Web cluster that is supported by a Juniper DX device. The measures
made by this test are as
follows:
| Measurement |
Description |
Measurement
Unit |
Interpretation |
| Active_requests |
The number of active HTTP requests to the cluster |
Number
|
|
| 300_errors |
The number of HTTP requests with response code between 300-399 in the last measurement period |
Number
|
300 responses could indicate page caching on the client browsers. Alternatively 300 responses could also indicate redirection of requests. A sudden change in this value could indicate a problem condition. |
| 400_errors |
The number of HTTP requests with response code between 400-499 |
Number
|
A high value indicates a number of missing/errored pages. |
| 500_errors |
The number of HTTP requests with response code between 500-599 in the last measurement period |
Number
|
Since responses with a status code of 500-600 indicate server side processing errors, a high value reflects an error condition. |
