SWS Instances HTTP Test
When you use virtual servers you can offer companies or individuals domain names, IP addresses, and some server monitoring capabilities with a single installed server.
All virtual servers have an HTTP Listener specified. When a new request comes in, the web server determines which virtual server to send it to based on the configured HTTP Listener.
This test monitors the HTTP requests to and responses from each virtual server configured on a web server instance, and thus reveals the quality of the HTTP service on the virtual servers.
Target of the test : An Oracle iPlanet Web Server
Agent deploying the test : An internal agent
Outputs of the test : One set of results for the each virtual server configured on the Oracle iPlanet web server instance being monitored.
Parameter | Description |
---|---|
Test period |
How often should the test be executed. |
Host |
The host for which the test is to be configured. |
Port |
The port number at which the specified Host listens to. |
User |
Specify the name of the administrator of the administration server to which the target web server is registered. |
PasswdFile |
The eG agent connects to the administration server to which the target web server is registered to extract the required metrics. To enable the eG agent to communicate with this administration server, you first need to create a password file containing the administrator password for accessing the server; this password file should be created in the install directory of the web server. Specify the name of this file in the PasswdFile text box; by default, this is admin.passwd. |
AdminServer |
Specify the IP address of the administration server to which the target web server is registered. |
AdminPort |
Indicate the port at which the administration server listens. |
Config |
In Web Server 7.0, all configurable elements of a server instance like web applications, configuration files, and search collection indexes are logically grouped and termed as a Configuration. To enable the test to locate the web server instance to be monitored, you need to mention the Configuration that applies to the instance. In the Config text box therefore, specify the name of the Configuration which the target web server instance uses. |
Node |
Node is a network resource, such as a server or a host. Instance refers to the environment of a web server daemon on a given node, including its configuration, log files and other runtime artifacts such as lock databases, caches and temporary files. To enable the test to identify the exact web server instance to be monitored, you need to specify the name of the Node on which the instance executes. The test will thus monitor only that web server instance that operates on the given Node and which uses the specified Config. |
SSL |
Set this flag to Yes if the administration server is SSL-enabled; if not, set it to No. |
WebServerDir |
Here, specify the Oracle iPlanet web server installation directory. |
Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Requests |
Indicates the rate of requests to this virtual server. |
Reqs/Sec |
|
No. of requests |
Indicates the number of requests to this virtual server during the last measurement period. |
Number |
|
No. of errors |
Indicates the number of errors logged on this virtual server during the last measurement period. |
Number |
Ideally, this value should be 0. |
No. of open connections |
Indicates the number of connections currently open on this virtual server . |
Number |
|
Data received |
Indicates the rate of data received by this virtual server. |
KB/Sec |
|
Data transmitted |
Indicates the rate of data transmitted by this virtual server. |
KB/Sec |
|
No of 200 responses |
Indicates the number of HTTP responses sent out by this virtual server during the last measurement period, with the 200 code. |
Number |
The 200 response is the standard response for successful HTTP requests. |
Successful responses |
Indicates the number of successful responses sent out by this virtual server during the last measurement period. |
Number |
The value of this measure typically represents the number of responses with the 2xx code. This class of status codes indicates the action requested by the client was received, understood, accepted and processed successfully. |
No of 302 responses |
Indicates the number of responses sent out by this virtual server during the last measurement period, with the 302 code. |
Number |
The 302 response indicates that the requested resource has been found under a different URI but the client should continue to use the original URI. |
No. of 304 responses |
Indicates the number of responses sent out by this virtual server during the last measurement period, with the 304 code. |
Number |
The 304 response indicates that the resource has not been modified since the last request. |
Redirection |
Indicates the number of responses with the 3xx code that were sent out by this virtual server during the last measurement period. |
Number |
This class of status code indicates that further action needs to be taken by the user agent in order to fulfill the request. The action required may be carried out by the user agent without interaction with the user if and only if the method used in the second request is GET or HEAD. A user agent should not automatically redirect a request more than five times, since such redirections usually indicate an infinite loop. |
No of 400 responses |
Indicates the number of responses with the 400 code that were sent out by this virtual server during the last measurement period. |
Number |
This type of response indicates that the request contains bad syntax or cannot be fulfilled. |
No of 401 responses |
Indicates the number of responses with the 401 code that were sent out by this virtual server during the last measurement period. |
Number |
This type of response indicates that the request needs user authentication. |
No of 403 responses |
Indicates the number of responses with the 403 code that were sent out by this virtual server during the last measurement period. |
Number |
This type of response indicates that the the request was a legal request, but the server is refusing to respond to it. |
No of 404 responses |
Indicates the number of responses with the 404 code that were sent out by this virtual server during the last measurement period. |
Number |
This type of response indicates that the document/file requested by the client was not found. |
|
Client errors responses: Indicates the number of responses with the 4xx code that were sent out by this virtual server during the last measurement period. |
Number |
Normally, value of the measure should be 0. A nonzero value indicates there are some problems with the requested content. |
No of 503 responses |
Indicates the number of responses with the 503 code that were sent out by this virtual server during the last measurement period. |
Number |
The 503 code indicates that the request was unsuccessful due to the server being down or overloaded. |
Server errors responses |
Indicates the number of responses with the 5xx code that were sent out by this virtual server during the last measurement period. |
Number |
Response status codes beginning with the digit "5" indicate cases in which the server is aware that it has encountered an error or is otherwise incapable of performing the request. Normally, the value of the measure should be 0. A nonzero value indicates there are some errors in the web server. |
