```
    Description copied from interface: MetricsFactory
    
    Creates a gauge with the given gauge name and set of tags. The actual metric name is a combination of those two values. The timer starts at 0.
    
    Specified by:
    
    createGauge in interface MetricsFactory
    
    Parameters:
    
    name - the gauge name
    
    tags - the tags to add to the gauge
    
    Returns:

```
public long getCounter(java.lang.String name,
                       java.lang.String tags)
```
    Returns the counter value information for the counter with the given metric name. Note that the metric name is not the counter name, as a metric name usually includes the tags.
    
    Parameters:
    
    name - the metric name, which includes the tags
    
    tags - the metric tags as comma separated list of entries, like "foo=bar,baz=qux"
    
    Returns:
    
    the counter value or -1, if no counter exists for the given metric name
  - getCounter
```
public long getCounter(java.lang.String name,
                       java.util.Map<java.lang.String,java.lang.String> tags)
```
    Returns the counter value information for the counter with the given metric name. Note that the metric name is not the counter name, as a metric name usually includes the tags.
    
    Parameters:
    
    name - the metric name, which includes the tags
    
    tags - the metric tags
    
    Returns:
    
    the counter value or -1, if no counter exists for the given metric name
  - getGauge
```
public long getGauge(java.lang.String name,
                     java.lang.String tags)

    Returns the current value for the gauge with the given metric name. Note that the metric name is not the gauge name, as a metric name usually includes the tags.
    
    Parameters:
    
    name - the metric name, which includes the tags
    
    tags - the metric tags as comma separated list of entries, like "foo=bar,baz=qux"
    
    Returns:
    
    the gauge value or -1, if no gauge exists for the given metric name
  - getGauge

                     java.util.Map<java.lang.String,java.lang.String> tags)
```
    Returns the current value for the gauge with the given metric name. Note that the metric name is not the gauge name, as a metric name usually includes the tags.
    
    Parameters:
    
    name - the metric name, which includes the tags
    
    tags - the metric tags
    
    Returns:
    
    the gauge value or -1, if no gauge exists for the given metric name
