Abstract

A method, system and computer program product are provided to allow the status of components obtained through JMX queries to be loaded asynchronously in web content such that the status value of each component is displayed as soon as it becomes available, without having to wait for the completion of any other query.

Claims

1. A method for displaying JMX monitoring information, comprising:

receiving a request for a web page containing the status of a plurality of system components;

calling a first servlet operable to;

generate a plurality of image tags, each corresponding to one of the components and pointing to an instance of a second servlet, each image tag comprising information to perform a JMX query; and

generate an HTML file comprising the plurality of image tags;

loading in a web browser the web page based on the HTML file;

transmitting requests to the instances of the second servlet substantially in parallel for images represented by each image tag; and

for each instance of the second servlet;

performing a JMX query based upon the information within the image tag;

receiving a response from the JMX query, the response including a value representative of the status of the corresponding component;

generating an image comprising the returned value;

transmitting the image to the browser; and

displaying the image.

2. The method of claim 1, wherein displaying the image of a returned value representing the status of a corresponding component is not dependent upon the display of the image of a returned value representing the status of any other component.

3. A JMX status monitoring tool, comprising:

a client device;

a browser running on the client device;

a plurality of system components, each component having a current status;

a plurality of instances of a first servlet, each instance corresponding to one of the plurality of system components; and

a second servlet callable from the browser and programmed to;

generate a plurality of image tags, each corresponding to one of the plurality of components and pointing to an instance of a first servlet, each image tag comprising information to perform a JMX query; and

generate an HTML file comprising the plurality of image tags;

the browser programmed to;

load a web page based on the HTML file; and

transmit requests to the instances of the first servlet substantially in parallel for images represented by each image tag; and

each instance of the first servlet programmed to;

perform a JMX query based upon the information within the image tag;

receive a response from the JMX query, the response including a value representative of the status of the corresponding component;

generate an image comprising the returned value;

transmit the image to the browser; and

display the image.

4. The status monitoring tool of claim 3, wherein displaying the image of a returned value representing the status of a corresponding component is not dependent upon the display of the image of a returned value representing the status of any other component.

5. A computer program product of a computer readable medium usable with a programmable computer, the computer program product having computer-readable code embodied therein for displaying JMX monitoring information, the computer-readable code comprising instructions for:

receiving a request for a web page containing the status of a plurality of system components;

calling a first servlet operable to;

generate a plurality of image tags, each corresponding to one of the components and pointing to an instance of a second servlet, each image tag comprising information to perform a JMX query; and

generate an HTML file comprising the plurality of image tags;

loading in a web browser the web page based on the HTML file;

transmitting requests to the instances of the second servlet substantially in parallel for images represented by each image tag; and

for each instance of the second servlet;

performing a JMX query based upon the information within the image tag;

receiving a response from the JMX query, the response including a value representative of the status of the corresponding component;

generating an image comprising the returned value;

transmitting the image to the browser; and

displaying the image.

6. The program product of claim 5, wherein displaying the image of a returned value representing the status of a corresponding component is not dependent upon the display of the image of a returned value representing the status of any other component.
