we can log all redis requests
how did admin measured Redis traffic for 1 site only?

BTW did you try to use memcached or couchbase instead of redis?

How do we log all requests for Redis to trace the problem? I think he used some tool to measure Redis traffic for sites. Because of excessive load on servers we restarted Redis again and traffic started dropping again since yesterday. Not tried memcached or couchbase as I have been using Redis for years, only since traffic started growing Redis started giving issues.

Well, in this case may му we should try couchbase for example?
it take like 15 minutes to install it - so why not?

Hi,

1.)Is Couchbase better than Redis for high traffic sites?
2.)Does it need any kind of tuning?
3.)Where to download it from?
4.) Do we need to install any php extension for Couchbase?

Hi,
While passing the Redis traffic for a site on another network interface we found that the site is using 1 GBps of bandwith, how is this possible if its only html files stored in cache? Other site with almost same traffic is using 10 times lesser bandwith on Redis. The only difference is that the site using maximum bandwith is https site and in Alternative hosts instead of cdn.domainname.com an using https://cdn.domainname.com . Is it possible that Redis could be storing the thumbs in cache also?

How do we see what Redis is storing in real time on the server? I'm really having a tough time with this and need help.

Hi,
Admin said this:

"I tried to use this command, but the things are happening so fast there and so many of them(almost 3Gbit for the whole usage), so my console just locking out with lots of data(thousands of lines per second). I can store some output in a file and provide to you to analyze."

Any idea how to find out why Redis is using so much bandwidth?
