+# Pegasus Java Client
+
+[![Test - java client](https://github.com/apache/incubator-pegasus/actions/workflows/test_java-client.yml/badge.svg)](https://github.com/apache/incubator-pegasus/actions/workflows/test_java-client.yml)
+
+## Build
+
+```
+mvn clean package -DskipTests
+```
+
+## Install
+
+```
+mvn clean install -DskipTests
+```
+
+## Test
+
+To run test, you should start pegasus onebox firstly, and run test as:
+
+```
+mvn clean package
+```
+
+or specify one test:
+
+```
+mvn clean package -Dtest=TestPing
+```
+
+## Configuration
+
+Configure client by "pegasus.properties", for example:
+
+```
+meta_servers = 127.0.0.1:34601,127.0.0.1:34602,127.0.0.1:34603
+operation_timeout = 1000
+async_workers = 4
+enable_perf_counter = true
+perf_counter_tags = k1=v1,k2=v2,k3=v3
+push_counter_interval_secs = 10
+```
+
+You can provide a parameter of 'configPath' when creating a client instance.
+
+The format of 'configPath' should be one of these:
+* zk path: zk://host1:port1,host2:port2,host3:port3/path/to/config
+* local file path: file:///path/to/config
+* resource path: resource:///path/to/config
+
+## PerfCounter(Metrics)
+
+Pegasus Java Client supports QPS and latency statistics of requests.
+
+The related configurations are:
+
+```
+enable_perf_counter = true
+perf_counter_tags = k1=v1,k2=v2,k3=v3
+push_counter_interval_secs = 10
+```
+
+For each type of request(get, set, multiset, etc.), we collect 8 metrics:
+1. cps-1sec: the request's qps
+2. cps-1min: the request's queries per 1 minute
+3. cps-5min: the request's queries per 5 minutes
+4. cps-15min: the request's queries per 15 minutes
+5. latency-p50: the moving median of request's queries
+6. latency-p99: the moving p99 of request's queries
+7. lantecy-p999: the moving p999 of request's queries
+8: latency-max: the moving max of request's queries
+
+We use io.dropwizard.metrics library to calculate the request count.
+
+Currently, metrics are integrated with open-falcon(https://open-falcon.org/),
+<!-- markdown-link-check-disable -->
+which push counters to local http agent http://127.0.0.1:1988/push/v1.
+<!-- markdown-link-check-enable-->
+
+If you'd like to integrate pegasus client with other monitor system, please let us know ASAP.
