JCoDestinationMonitor (SAP HANA Cloud Platform SDK)

```
public interface JCoDestinationMonitor
```
The destination monitor provides some details about a destination. The monitor instance will be created by aDestinationInstance.getMonitor() or by JCo.getDestinationMonitor(id), where id is a value of JCo.getDestinationIDs().

- Method Detail
  - getDestinationID
```
String getDestinationID()
```
    Returns the ID of the destination instance that is monitored by this instance.
    
    Returns:
    destination ID as string
  - getOriginDestinationID
```
String getOriginDestinationID()
```
    Returns the ID of the destination instance that the monitored destination instance originated from. This is relevant if monitoring a JCoCustomDestination instance. In case of monitoring a configured destination instance, it will return null.
    
    Returns:
    origin destination ID as string or null
  - getPoolCapacity
```
int getPoolCapacity()
```
    Returns the maximum number of client connections that will be held open for the monitored destination instance.
    
    Returns:
    the size of the associated client connection pool
    
    Throws:
    
    JCoRuntimeException - with key JCO_ERROR_DESTINATION_DATA_INVALID if the monitored destination instance is invalid
  - getPeakLimit
```
int getPeakLimit()
```
    Returns the maximum number of client connections that can be used simultaneously with the monitored destination instance.
    
    Returns:
    the peak limit of the associated client connection pool
    
    Throws:
    
    JCoRuntimeException - with key JCO_ERROR_DESTINATION_DATA_INVALID if the monitored destination instance is invalid
  - getUsedConnectionCount
```
int getUsedConnectionCount()
```
    Returns the number of client connections that are currently being used with the monitored destination instance.
    
    Returns:
    the number of currently used client connections
    
    Throws:
    
    JCoRuntimeException - with key JCO_ERROR_DESTINATION_DATA_INVALID if the monitored destination instance is invalid
  - getPooledConnectionCount
```
int getPooledConnectionCount()
```
    Returns the number of client connections that are currently held open for the monitored destination instance.
    
    Returns:
    the number of currently held open client connections by the associated client connection pool
    
    Throws:
    
    JCoRuntimeException - with key JCO_ERROR_DESTINATION_DATA_INVALID if the monitored destination instance is invalid
  - getMaxUsedCount
```
int getMaxUsedCount()
```
    Returns the maximum number of simultaneously used client connections with the monitored destination instance.
    
    Returns:
    the maximum number of client connections that have been used simultaneously
    
    Throws:
    
    JCoRuntimeException - with key JCO_ERROR_DESTINATION_DATA_INVALID if the monitored destination instance is invalid
  - getWaitingThreadCount
```
int getWaitingThreadCount()
```
    Returns the number of threads that are currently waiting for a free connection to be used with the monitored destination instance.
    
    Returns:
    the number of threads that are currently waiting for a connection to get from the associated client connection pool
    
    Throws:
    
    JCoRuntimeException - with key JCO_ERROR_DESTINATION_DATA_INVALID if the monitored destination instance is invalid
    Since:
    
    3.0.9
  - getLastActivityTimestamp
```
long getLastActivityTimestamp()
```
    Returns the time stamp of the last activity done with the monitored destination instance.
    
    Returns:
    the last activity time stamp in ms
    
    Throws:
    
    JCoRuntimeException - with key JCO_ERROR_DESTINATION_DATA_INVALID if the monitored destination instance is invalid
  - getConnectionsData
```
List<? extends JCoConnectionData> getConnectionsData()
```
    Creates and returns a list of all client connections that are currently used with or held open by the monitored destination instance.
    
    Returns:
    a list of JCoConnectionData objects describing all open client connections
    
    Throws:
    
    JCoRuntimeException - with key JCO_ERROR_DESTINATION_DATA_INVALID if the monitored destination instance is invalid
  - isValid
```
boolean isValid()
```
    Returns true if the monitored destination instance is valid, i.e. it has neither been changed nor removed.
    
    Returns:
    true if the monitored destination instance is valid; false otherwise
