SWS Instances Test
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.
This test reports useful performance statistics related to a web server instance, which indicate the following:
- How long has the instance been up and running?
- How quickly does the instance respond to requests? Is there a processing bottlneck on the server instance?
- Have any been errors been captured on the instance?
- How is the data traffic to and from the instance?
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 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. |
Detailed Diagnosis |
To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:
|
Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Instance running time |
Indicates the total time for which the instance has been up and running. |
Secs |
By observing the variations in this measure over time, you can determine whether there were frequent breaks in the availability of the instance. The detailed diagnosis of this measure (if enabled) displays starting time of the instance. |
Requests |
Indicates the rate of requests to all the virtual servers in the instance. |
Reqs/Sec |
|
No. of errors |
Indicates the number of errors logged on all the virtual servers in the instance during the last measurement period. |
Number |
Ideally, this value should be 0. |
Maximum response time |
Indicates the maximum response time of all virtual servers since the instance was up. |
Secs |
A low response time is typically desired. A high value of this measure could indicate a processing bottleneck on the web server instance or a network congestion. |
Avg res time in Last5min |
Average response time of all virtual servers in the instance during last 5 minutes. |
Secs |
|
Data transmitted |
Indicates the rate of data transmitted by this instance. |
KB/Sec |
|
Data received |
Indicates the rate of data received by this instance. |
KB/Sec |
