ConsoleReporter

ConsoleReporter
previously created by a call to
addConsoleReporter(Duration)
and release it for GC. Idempotent
between calls to the associated add method. Does nothing before the first
call to the associated add method.public void addCsvReporter(Duration reportInterval, String output)
CsvReporter
attached to the JanusGraph Metrics registry.
The output
argument must be non-null but need not exist. If it
doesn't already exist, this method attempts to create it by calling
File.mkdirs()
.
reportInterval
- time to wait between dumping metrics to CSV files in
the configured directoryoutput
- the path to a directory into which Metrics will periodically
write CSV datapublic void removeCsvReporter()
CsvReporter
previously created by a call to
addCsvReporter(Duration, String)
and release it for GC. Idempotent
between calls to the associated add method. Does nothing before the first
call to the associated add method.public void addJmxReporter(String domain, String agentId)
JmxReporter
attached to the JanusGraph Metrics registry.
If domain
or agentId
is null, then Metrics's uses its own
internal default value(s).
If agentId
is non-null, then
MBeanServerFactory.findMBeanServer(String agentId)
must return exactly
one MBeanServer
. The reporter will register with that server. If
the findMBeanServer(String agentId)
call returns no or multiple servers,
then this method logs an error and falls back on the Metrics default for
agentId
.
domain
- the JMX domain in which to continuously expose metricsagentId

JmxReporter
previously created by a call to
addJmxReporter(String, String)
and release it for GC. Idempotent
between calls to the associated add method. Does nothing before the first
call to the associated add method.public void addSlf4jReporter(Duration reportInterval, String loggerName)
Slf4jReporter
attached to the JanusGraph Metrics registry.
If loggerName
is null, or if it is non-null but
LoggerFactory.getLogger(Class loggerName)
returns null, then Metrics's
default Slf4j logger name is used instead.

GangliaReporter
attached to the JanusGraph Metrics registry.
groupOrHost
and addressingMode
must be non-null. The
remaining non-primitive arguments may be null. If protocol31
is
null, then true is assumed. Null values of hostUUID
or
spoof
are passed into the GMetric
constructor, which
causes Ganglia to use its internal logic for generating a default UUID
and default reporting hostname (respectively).

GraphiteReporter
attached to the JanusGraph Metrics registry.
If prefix
is null, then Metrics's internal default prefix is used
(empty string at the time this comment was written).
