Frequently Asked Questions

Protocol Adaptors

1. What are adaptors? What are the different adaptors supported by multi-protocol agent?
2. Can the notifications sent by the agent be accessed by all the supported manager applications?
3. Can existing management information be monitored through multi-protocol agent via SNMP?
4. Is there a way to monitor management information without storing them in the agent's memory?
5. Is there an option to represent SNMP-related information in HTML browser?
6. What is SSL support in HTML, RMI, and HTTP adaptors?

1.What are adaptors? What are the different adaptors supported by multi-protocol agent?

When MBeans get registered to the MBean Server, a protocol is required to interact with these MBeans and retrieve the information for the request sent from the management applications. This is enabled by protocol adaptors that convert the management application data into standard protocol information.

The different adaptors supported by multi-protocol agents are SNMP, TL1, RMI, CORBA, HTTP, and HTML.

Questions

2.Can the notifications sent by the agent be accessed by all the supported manager applications?

Yes.

Questions

3. Can existing management information be monitored through multi-protocol agent via SNMP?

Yes. This is implemented through SNMP adaptor which makes the multi-protocol agent function as an SNMP agent. For more information about SNMP adaptors, refer to "SNMP Adaptor" section of the help documentation.

Questions

4. Is there a way to monitor management information without storing them in the agent's memory?  

Yes. Agent Toolkit supports user storage model by which the user can store the management data in an external application such as database. This enables external persistance support rather than the multi-protocol agent holding them in memory. Please refer to the topic "External storage of data for Tables"  in the help documentation to know more about the implementation.

Questions

5. Is there an option to represent SNMP-related information in HTML browser?

Yes. The SNMP information (except the OID for which the request is sent) can be viewed in the HTML browser through HTML adaptor. This is implemented by connecting the HTML adaptor to the MBean server, which then translates the incoming request into HTTP and exposes the MBean attribute changes through the HTML/Web browser.

Questions

6. What is SSL support in HTML, RMI, and HTTP adaptors?

SSL refers to the Secure Sockets Layer protocol,  which provides authenticated and encrypted communication between clients and servers.  To configure SSL support for the HTTP Agent, please refer to SSL parameters.
