Examples with Metered com.codahale.metrics.Metered used on opensource projects

Example 1 with Metered

use of com.codahale.metrics.Metered in project cassandra by apache.

the class TableMetricTables method buildMetadata.

/**
 *  Identify the type of Metric it is (gauge, counter etc) abd create the TableMetadata. The column name
 *  and type for a counter/gauge is formatted differently based on the units (bytes/time) so allowed to
 *  be set.
 */
private static TableMetadata buildMetadata(String keyspace, String table, Function<TableMetrics, ? extends Metric> func, String colName, AbstractType colType, String suffix) {
    TableMetadata.Builder metadata = TableMetadata.builder(keyspace, table).kind(TableMetadata.Kind.VIRTUAL).addPartitionKeyColumn(KEYSPACE_NAME, UTF8Type.instance).addPartitionKeyColumn(TABLE_NAME, UTF8Type.instance).partitioner(PARTITIONER);
    // get a table from system keyspace and get metric from it for determining type of metric
    Keyspace system = Keyspace.system().iterator().next();
    Metric test = func.apply(system.getColumnFamilyStores().iterator().next().metric);
    if (test instanceof Counting) {
        metadata.addRegularColumn(colName, colType);
        // if it has a Histogram include some information about distribution
        if (test instanceof Sampling) {
            metadata.addRegularColumn(P50 + suffix, DoubleType.instance).addRegularColumn(P99 + suffix, DoubleType.instance).addRegularColumn(MAX + suffix, DoubleType.instance);
        }
        if (test instanceof Metered) {
            metadata.addRegularColumn(RATE, DoubleType.instance);
        }
    } else if (test instanceof Gauge) {
        metadata.addRegularColumn(colName, colType);
    }
    return metadata.build();
