        public InfluxExporter​(java.lang.String url,
                      java.lang.String user,
                      java.lang.String password,
                      java.lang.String database,
                      java.lang.String retention,
                      boolean createDatabase,
                      boolean exportDifference,
                      java.util.function.Function<java.lang.String,​java.lang.String> measurementNameProvider)
        Creates a new influx Exporter. The export does not export by itself, but instead has to be triggered manually by calling export(); This can be done periodically for example using ScheduledExecutorService.scheduleAtFixedRate(Runnable, long, long, TimeUnit).
        Parameters:
        url - The http url of the influx to connect to
        user - the user to use when connecting to influx, can be null
        password - the password to use when connecting to influx, can be null
        database - the influx database to
        retention - the retention policy of the database to write to
        createDatabase - if true, the exporter will create the specified database with an "autogen" policy when it connects
        measurementNameProvider - a function to use for resolving the measurement names for custom metrics. By default, this is done by finding the measure corresponding to a view. If this function returns a non-null value, the provided measurement name is used instead.

    • Method Detail

      • export

        public void export()
        Fetches all metrics from OpenCensus and attempts to export them to Influx. No exception is thrown in case of a failure, instead the data is just not written and the error is logged.

      • close

        public void close()
        Closes the underlying InfluxDB connection. If export() is invoked after close(), the connection will be opened again.
