Class FileMetricsPublisher

java.lang.Object
com.j256.simplemetrics.utils.FileMetricsPublisher
All Implemented Interfaces:
MetricsUpdater
public class FileMetricsPublisher extends Object implements MetricsUpdater
Exposes metrics that can be found from files on file-system. This is often used to read from the /proc file-system under Linux. Metrics are configured with the FileMetric class. A common file metric is the number of open file-descriptors being used by the JVM.

NOTE: If you are using the no-arg constructor (like with Spring) you will need to make sure that initialize() is called.
