The redis INFO commad returns the string like redis_version:2.2.14\r\nredis_git_sha1:00000000\r\nredis_git_dirty:0\r\narch_bits:32
How can I convert the string to get a JSON object something like
{
"redis_version":"x",
"key2":"value"
}

I don't know why would you want to do that, but here's a simple example:
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;
}

Thanks for the reply... but is there any simple solution instead of the workaround like above?

It is a simple solution and it is not a workaround. What did you expect? That a string will magically parse itself?

I think even redis authors do encourage people to parse it on their own, since it's a relatively simple string to parse.
You can use node-redis-info:
npm install redis-info
Usage:
> var parser = require('redis-info');
undefined
> var info = parser.parse(redis_info_str);
undefined
> info.fields.redis_version
2.6.1
> info.startWith('pubsub')
[ [ 'pubsub_channels', '2' ],
[ 'pubsub_patterns', '0' ] ]
> info.contains('memory')
[ [ 'used_memory', '15080416' ],
[ 'used_memory_human', '14.38M' ],
[ 'used_memory_rss', '21258240' ],
[ 'used_memory_peak', '18985904' ],
[ 'used_memory_peak_human', '18.11M' ] ]

Simple:
#!/usr/bin/env python
import redis
import json
print(json.dumps(redis.Redis().info()))
For zabbix Template DB Redis:
#!/usr/bin/env python
import redis
import json
import sys
r = redis.Redis.from_url(sys.argv[1])
a = {}
sections = ["CPU","Clients","Cluster","Keyspace","Memory","Modules","Persistence","Replication","Server","Stats"]
for section in sections:
a[section]=r.info(section)
print(json.dumps(a))
interface RedisInfo {
[key: string]: any;
}
/**
* This was taken from how `.serverInfo` was parsed in the ioredis library
* https://github.com/luin/ioredis/blob/f275bc24de3825f80415a69ff227a45251dd1a3b/lib/redis/index.ts#L500
* @param infoString Result of Redis INFO command
*/
const parseRedisInfo = (infoString: string): RedisInfo => {
const info: RedisInfo = {};
const lines = infoString.split('\r\n');
for (let i = 0; i < lines.length; ++i) {
const parts = lines[i].split(':');
if (parts[1]) {
info[parts[0]] = parts[1];
}
}
return info;
};
