|
|
|
||
|
|
[source,java]

|
|
--------------------------------------------------
|
||
|
|
WatcherStatsResponse watcherStatsResponse = watcherClient.prepareWatcherStats().get();
|
||
|
|
--------------------------------------------------
|
||
|
|
|
||
|
|
A successful call returns a response structure that can be accessed as shown:

WatcherBuild build = watcherStatsResponse.getBuild();
|
||
|
|
|
||
|
|
// The Version of watcher currently running
|
||
|
|
WatcherVersion version = watcherStatsResponse.getVersion();
|
||
|
|
|
||
|
|
// The current size of the watcher execution queue
|
||
|
|
long executionQueueSize = watcherStatsResponse.getExecutionQueueSize();
|
||
|
|
|
||
|
|
// The maximum size the watch execution queue has grown to
|
||
|
|
long executionQueueMaxSize = watcherStatsResponse.getWatchExecutionQueueMaxSize();
|
||
|
|
|
||
|
|
// The total number of watches registered in the system
|
||
|
|
long totalNumberOfWatches = watcherStatsResponse.getWatchesCount();
|
||
|
|
|
||
|
|
// Watcher state (STARTING,STOPPED or STARTED)
