Well known configuration defaults and constants for Ganglia.

Field Summary

Fields
Modifier and Type	Field and Description
`static int`	`BUFFER_SIZE` The maximum size of an XDR message (as per libgmond.c).
`static int`	`DEFAULT_DMAX` Time in seconds after weak a counter which has not been reported will be purged -or- ZERO (0) to never purge a counter.
`static String`	`DEFAULT_GROUP` The well known multicast address for ganglia service groups.
`static int`	`DEFAULT_PORT` The well known port against which ganglia is deployed.
`static GangliaSlopeEnum`	`DEFAULT_SLOPE` The default "slope" used to shape curves in RRDTOOL.
`static int`	`DEFAULT_TMAX` The default time after which ganglia should expect a new value for a metric (TMAX).
`static String`	`DEFAULT_UNITS` The default units for reported metrics (ganglia allows metadata for a metric to indicate its base unit).
`static int`	`HEARTBEAT_INTERVAL` The default heartbeat interval for ganglia hosts.
`static int`	`INITIAL_DELAY` The waiting period in seconds before the first reporting pass.
`static int`	`MONITORING_INTERVAL` The interval at which metrics which are collected on this node.
`static int`	`QUIET_PERIOD` The duration in seconds of the quiet period after a ganglia service start.

- Field Detail
  - DEFAULT_GROUP
```
static final String DEFAULT_GROUP
```
    The well known multicast address for ganglia service groups.

    Constant Field Values
  - DEFAULT_PORT
```
static final int DEFAULT_PORT
```
    The well known port against which ganglia is deployed.

    Constant Field Values
  - BUFFER_SIZE
```
static final int BUFFER_SIZE
```
    The maximum size of an XDR message (as per libgmond.c).
    
    See Also:
    Constant Field Values
  - QUIET_PERIOD
```
static final int QUIET_PERIOD
```
    The duration in seconds of the quiet period after a ganglia service start. During the quiet period a ganglia service will not reset the timestamp associated with its counters in response to a metadata request. This is done to avoid multicast storms when several services are restarted during a short interval.
    
    See Also:
    Constant Field Values
  - INITIAL_DELAY
```
static final int INITIAL_DELAY
```
    The waiting period in seconds before the first reporting pass.
    Note: The core ganglia metrics will be self-declared once this period has expired if they have not already been observed by listening to the ganglia network.
    
    See Also:
    Constant Field Values
  - HEARTBEAT_INTERVAL
```
static final int HEARTBEAT_INTERVAL
```
    The default heartbeat interval for ganglia hosts.
    Note: Use ZERO (0) if you are running gmond on the same host. That will prevent the GangliaService from transmitting a different heartbeat, which would confuse gmond and gmetad.
    The GangliaService MUST NOT send out a heartbeat if gmond is also running on the host since the two heartbeats will be different (they are the start time of gmond) and gmond and gmetad will both get confused.
    
    See Also:
    Constant Field Values
  - MONITORING_INTERVAL
```
static final int MONITORING_INTERVAL
```
    The interval at which metrics which are collected on this node.
    Each time an updated metric is examined, its current value is copied into the internal state maintained by this service. If the metric value has never been published (timestamp is ZERO (0)), if TMax might expire before we sample the metric again, or if the value of the metric has changed "sufficiently" then the metric will be sent to any configured listener(s).

    MONITORING_INTERVAL, Constant Field Values
  - DEFAULT_SLOPE
```
static final GangliaSlopeEnum DEFAULT_SLOPE
```
    The default "slope" used to shape curves in RRDTOOL.
    
    See Also:
    GangliaSlopeEnum
  - DEFAULT_TMAX
```
static final int DEFAULT_TMAX
```
    The default time after which ganglia should expect a new value for a metric (TMAX). This value is only advisory. Metric data are not purged until DMAX is exceeded. Values which remain unchanged are not retransmitted unless TMAX might be exceeded before their next reporting period.
    
    See Also:
    Constant Field Values
  - DEFAULT_DMAX
```
static final int DEFAULT_DMAX
```
    Time in seconds after weak a counter which has not been reported will be purged -or- ZERO (0) to never purge a counter.
    
    See Also:
    Constant Field Values
  - DEFAULT_UNITS
```
static final String DEFAULT_UNITS
```
    The default units for reported metrics (ganglia allows metadata for a metric to indicate its base unit).
