20.10. Other Management Tools and Operations
Managing Red Hat JBoss Data Grid instances requires exposing significant amounts of relevant statistical information. This information allows administrators to get a clear view of each JBoss Data Grid node's state. A single installation can comprise of tens or hundreds of JBoss Data Grid nodes and it is important to provide this information in a clear and concise manner. JBoss Operations Network is one example of a tool that provides runtime visibility. Other tools, such as JConsole can be used where JMX is enabled.
20.10.1. Accessing Data via URLs
复制链接链接已复制到粘贴板!
Caches that have been configured with a REST interface have access to Red Hat JBoss Data Grid using RESTful HTTP access.
The RESTful service only requires a HTTP client library, eliminating the need for tightly coupled client libraries and bindings.
HTTP
put() and post() methods place data in the cache, and the URL used determines the cache name and key(s) used. The data is the value placed into the cache, and is placed in the body of the request.
A Content-Type header must be set for these methods.
GET and HEAD methods are used for data retrieval while other headers control cache settings and behavior.
Note
It is not possible to have conflicting server modules interact with the data grid. Caches must be configured with a compatible interface in order to have access to JBoss Data Grid.
