The way to get the metrics is the same as getting other metrics. For example:
| Code Block | ||
|---|---|---|
| ||
TopicPartition tp = new TopicPartition("topic", 0);
HashMap<String, String> tags = new HashMap<>();
tags.put("client-id", "metricTestConsumer0");
double currentLag = consumer0.metrics().get(new MetricName(tp + ".records-lag", "consumer-fetch-manager-metrics", "", tags)).value()
double averageLag = consumer0.metrics().get(new MetricName(tp + ".records-lag-avg", "consumer-fetch-manager-metrics", "", tags)).value()
double maxLag = consumer0.metrics().get(new MetricName(tp + ".records-lag-max", "consumer-fetch-manager-metrics", "", tags)).value() |
