MetricClient metricClient = MetricClientBuilder.newBuilder()
        .unixDomainSocket(true)
        .prefix("your application metric name common prefix")
        .maxPacketBytes(8192)
        .build();

metricClient.close();

//without tags
metricClient.emitCounter("example_counter_metric");
metricClient.emitCounter("example_counter_metric", 3);

metricClient.emitTimer("example_timer_metric", 200);
metricClient.emitTimer("example_timer_metric", 200, TimeUnit.MILLISECONDS);

metricClient.emitGauge("example_gauge_metric", 100);

//with tags
Map<String, String> tags = new HashMap<>();
tags.put("tagKey", "tagValue");
metricClient.emitCounter("example_counter_metric",  tags);
metricClient.emitCounter("example_counter_metric", 3, tags);

metricClient.emitTimer("example_timer_metric", 200, tags);
metricClient.emitTimer("example_timer_metric", 200, TimeUnit.MILLISECONDS, tags);

metricClient.emitGauge("example_gauge_metric", 100, tags);

you can config client with MetricClientBuilder,there are some config items available in MetricConfig such as:

• prefix the common prefix of metric name
• unixDomainSocket use unix domain socket to send metric packet
• sockAddress domain unix socket address
• socketTimeOutMs send metric to agent socket timeout in milliseconds
• maxPacketBytes send metric to agent socket max packet bytes limit
• useMetricPool whether to use metric object pool
• metricPoolMinIdle metric object pool min idle
• metricPoolMaxIdle metric object pool max idle
• byteBufferPoolMinIdle byte buffer object pool min idle
• byteBufferPoolMaxIdle byte buffer object pool max idle
• reporterQueueCapacity reporter buffer queue capacity.metric will be discarded when the capacity is exceeded, you can increase this queue capacity or reporterWorkers or senderWorkers to avoid
• reporterWorkers number of reporter queue processor workers
• senderSync send packet sync or async
• senderWorkers number of sender queue processor workers if senderSync is false
• workerWaitSleepMs reporter and sender processor waiting for empty poll
