/**
 * IT cases for the {@link ElasticsearchSink}.
 *
 * <p>The Elasticsearch ITCases for 5.x CANNOT be executed in the IDE directly, since it is required that the
 * Log4J-to-SLF4J adapter dependency must be excluded from the test classpath for the Elasticsearch embedded
 * node used in the tests to work properly.
 *
 * <p>TODO: This is skipped now cause the test need cgroup conf to match the specific pattern, see
 * OsProbe#CONTROL_GROUP_PATTERN for details.
