Enum Constant Summary

Enum Constants
Enum Constant and Description
`EVENT_COUNT` The metric that records the number of `observation events` that have been sent to at least one listener.
`EVENT_QUEUE_SIZE` The metric that records the number of `observation events` that are in the queue and awaiting processing (and still have yet to be sent to the liseners).
`LISTENER_COUNT` The metric that records the number of `observation listeners` in existance during the window.
`NODE_CHANGES` The metric that captures the number of nodes that were created, updated, or deleted during the window as part of the `Session.save()`, `VersionManager.checkin(String)`, `Workspace.import` and other calls that change content.
`OPEN_SCOPED_LOCK_COUNT` The metric that records the number of `non-session-scoped` `JCR locks` in existance during the window.
`QUERY_COUNT` The metric that captures the number of `queries` that are executing during the window.
`SEQUENCED_COUNT` The metric that records the number of nodes that were sequenced.
`SEQUENCER_QUEUE_SIZE` The metric that records the number of nodes that were sequenced.
`SESSION_COUNT` The metric that captures the number of `sessions` that are open during the window.
`SESSION_SAVES` The metric that captures the number of `Session.save()` calls that have occurred during the window.
`SESSION_SCOPED_LOCK_COUNT` The metric that records the number of `session-scoped` `JCR locks` in existence during the window.
`WORKSPACE_COUNT` The metric that records the number of `workspaces` in existance during the window.

- Method Detail
  - values
```
public static ValueMetric[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (ValueMetric c : ValueMetric.values())
    System.out.println(c);
```
    Returns:
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ValueMetric valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    name - the name of the enum constant to be returned.
    
    Returns:
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - getLiteral
```
public String getLiteral()
```
    The literal string form of the value metric.
    
    Returns:
    the literal string form; never null or empty
  - getLabel
```
public String getLabel()
```
    The readable label for this metric.
    
    Returns:
    the human-readable label; never null or empty
  - getDescription
```
public String getDescription()
```
    Return the description for this metric.
    
    Returns:
    the description; never null or empty
  - isContinuous
```
public boolean isContinuous()
```
    Return whether this metric's values are continuous across multiple windows. In other words, the values of a continuous metric will increase and decrease over time.
    On the other hand, the values of a non-continous metric will have values that always start at zero at the beginning of a window.
    
    Returns:
    continuous
  - fromLiteral
```
public static ValueMetric fromLiteral(String literal)
```
    Get the ValueMetric that has the supplied literal.
    
    Parameters:
    literal - the literal (can be of any case); may not be null
    
    Returns:
    the value metric, or null if there is no ValueMetric enum value for the given literal string
