javascript - 如何使用 Node.js 获取 Redis 中的连接数？

Question

有没有办法检查 Redis 数据库的当前连接数？

const redis = require('redis');

var client = redis.createClient(port, host);

client.on('connect', () => {
  //Display how many current connections are to Redis
  console.log( numberOfRedisClients );
});

Answer 1

根据redis documentation尝试这个 :

const Redis = require("ioredis");
let client =  new Redis();
async function my_function(){
  console.log(await client.send_command('CLIENT', 'LIST'))

}

输出 :
