Tip
New development-and-diagnostics tool in Rhino 2.3.1.12

SBB Diagnostics lets you pull service-defined diagnostic information from SBB objects at runtime. You can use the getSbbDiagnostics console command (or associated MBean operation) to access diagnostic information (in String form) from particular methods implemented in the SBB Abstract class.

For an SBB to provide this diagnostics information, it must implement one of these methods:

  • String ocGetSbbDiagnostics(); — When queried with the getSbbDiagnostics console command, the return result from this method will be included in the SBB Diagnostics output.

  • void ocGetSbbDiagnostics(StringBuilder sb); — When queried with the getSbbDiagnostics console command, this method will be invoked on the SBB object with a SLEE-provided StringBuilder. The .toString() of the StringBuilder will be included in the SBB diagnostics output. This method is intended for chaining diagnostics output between extending classes and child SBBs.
Warning

  • A deployment error will occur if more than one of these methods is implemented.

  • The implementation of a ocGetSbbDiagnostics method should not modify SBB object state.

  • See the example below.

To get detailed diagnostics information about an SBB entity, use the following rhino-console command or related MBean operation.

Console command: getsbbdiagnostics

Command

 
getsbbdiagnostics <serviceid> <sbbid> <sbb pkeys>*
  Description
    Get SBB info and diagnostics (if supported by sbb implementation).

Example

To display information for SBB entity 101:146698001375232/-815184026 of the Sentinel SIP service:

$ ./rhino-console getsbbdiagnostics name=sentinel.sip,vendor=OpenCloud,version=1.0 name=sentinel.sip,vendor=OpenCloud,version=1.0 101:146698001375232/-815184026

This command returns a snapshot of the SBB entity’s state and SBB-defined diagnostics information at the time you execute it. Some values (such as pkey, parent-pkey, convergence-name, creating-node-id, creation-time, replicated, sbb-component-id, and service-component-id) are fixed for the lifetime of the SBB entity. Others change as the SBB entity processes events.

The diagnostics output (from the "SBB diagnostics:" line onwards) is free-form and SBB defined. The above output is only representative of a single service-defined diagnostics method.
Tip See SBB Entity Information Fields for a description of the fields getsbbdiagnostics returns.

MBean operation: getSbbDiagnostics

MBean

Rhino operation

 
public CompositeData getSbbDiagnostics(ServiceID serviceID, SbbID sbbID, String sbbPKey)
    throws ManagementException, InvalidPKeyException, UnrecognizedSbbException, UnrecognizedServiceException, UnknownSbbEntityException;

This operation returns tabular data with detailed information on the given SBB entity, including SBB-defined diagnostics information.
Note For a description of the format of the tabular data that this operation returns, see the javadoc.

Example usage

The following is a basic example showing an auto-generated ocGetSbbDiagnostics(StringBuilder sb) method. In this case, the method was generated based on CMP fields declared by the SBB, and demonstrates diagnostics information being obtained from both the current class and the super class:

---
public abstract class ExampleSessionStateImpl extends com.opencloud.sentinel.ant.BaseSbb implements ExampleSessionState {
    public void ocGetSbbDiagnostics(StringBuilder sb) {
        final String header = "ExampleSessionState Session State";
        sb.append(header).append("\n");
        for (int i=0; i < header.length(); i++)
          sb.append("=");
        sb.append("\n\n");
            // diagnostics: ClashingType (from com.opencloud.sentinel.ant.ExampleSessionStateInterface)
            if (getClashingType() == null) {
              sb.append("ClashingType: null\n");
            } else {
              sb.append("ClashingType: ").append(getClashingType()).append("\n");
            }
            // diagnostics: ExampleField (from com.opencloud.sentinel.ant.ExampleSessionStateInterface)
            if (getExampleField() == null) {
              sb.append("ExampleField: null\n");
            } else {
              sb.append("ExampleField: ").append(getExampleField()).append("\n");
            }
       sb.append("\n");
        super.ocGetSbbDiagnostics(sb);
    }
    ...
