How to find azure redis cache total memory using redis commond

1. Create Azure Redis Cache on portal.

2. Click Console.

3. Input info memory command, and check the output info. I believe maxmemory is you want.

4. Test Code.

    'use strict'

    var redis = require("redis");
    var bluebird = require("bluebird");

    const PORT=6380;
    const REDISCACHEHOSTNAME="jas***.windows.net";
    const REDISCACHEKEY="+tDRMmw********56ooVF7c=";

    // Convert Redis client API to use promises, to make it usable with async/await syntax
    bluebird.promisifyAll(redis.RedisClient.prototype);
    bluebird.promisifyAll(redis.Multi.prototype);

    async function testCache() {
        var cacheConnection = redis.createClient(PORT, REDISCACHEHOSTNAME, 
            {auth_pass: REDISCACHEKEY, tls: {servername: REDISCACHEHOSTNAME}});

        // Simple PING command
        console.log("\nCache command: info memory");
        let response=await cacheConnection.sendCommandAsync("info",["memory"]);
        let obj=parseInfo(response);
        console.log("Cache response : maxmemory = " + obj.maxmemory);
    }

    function parseInfo( info ) {
        var lines = info.split( "\r\n" );
        var obj = { };
        for ( var i = 0, l = info.length; i < l; i++ ) {
            var line = lines[ i ];
            if ( line && line.split ) {
                line = line.split( ":" );
                if ( line.length > 1 ) {
                    var key = line.shift( );
                    obj[ key ] = line.join( ":" );
                }
            }
        }
        return obj;
    }

    testCache();

5. Test Result.
