keyspace and table names in NodeInfo must be in lowercase.

[krolser]

In the JmxScraper.java inside method getMetricPath() properties is transformed to lowercase.

    private String getMetricPath(ObjectName mbeanName, MBeanAttributeInfo attr) {
        String properties = PATTERN.matcher(mbeanName.toString())
                .replaceAll(metricSeparator)
                .replace(' ', '_') + metricSeparator + attr.getName();
        return properties.toLowerCase();  <====
    }

It's work great with the cql tables because when you create table using CREATE TABLE <tablename> statement, cassandra lowercase <tablename>.

Statements below are same:

CREATE TABLE test.NAME ( id UUID PRIMARY KEY, lastname text);
CREATE TABLE test.Name ( id UUID PRIMARY KEY, lastname text);
CREATE TABLE test.nAmE ( id UUID PRIMARY KEY, lastname text);

Everything work fine. But, if you have tables created using cassandra-cli, their names isn't lowercased inside cassandra.

Condition

if (nodeInfo.keyspaces.contains(keyspaceName) && nodeInfo.tables.contains(tableName)) { <==
    STATS.labels(nodeInfo.clusterName, nodeInfo.datacenterName, keyspaceName, tableName, metricName).set(value);
    return;
}

not true and label table is not set.
