Method Details

handleProbe

public Map<String,String> handleProbe(String... keys)

Description copied from interface: DiagnosticsHandler.ProbeHandler

Handles a probe. For each key that is handled, the key and its result should be in the returned map.

Specified by:

handleProbe in interface DiagnosticsHandler.ProbeHandler

Returns:

A map of keys and values. A null return value is permissible.

supportedKeys

Description copied from interface: DiagnosticsHandler.ProbeHandler

Returns a list of supported keys

Specified by:

supportedKeys in interface DiagnosticsHandler.ProbeHandler

enable

 boolean flag)

resetAllStats

protected JChannel resetAllStats()

dumpAttrsAllProtocols

protected Map<String,Map<String,Object>> dumpAttrsAllProtocols()

Dumps the attributes and their values of _all_ protocols in a stack

Returns:

A map of protocol names as keys and maps (of attribute names and values) as values

dumpAttrsSelectedProtocol

protected Map<String,Map<String,Object>> dumpAttrsSelectedProtocol(String protocol_name,
 List<String> attrs)
