kandi X-RAY | play-redis Summary

play-redis is a Scala library typically used in Server, Caching applications. play-redis has no bugs, it has no vulnerabilities, it has a Weak Copyleft License and it has low support. You can download it from GitHub.

Play framework 2 is delivered with SyncCacheApi and AsyncCacheApi. This module provides implementation of a cache over Redis server, i.e., key/value storage. Besides the compatibility with all Play's cache APIs, it introduces more evolved API providing lots of handful operations. Besides the basic methods such as get, set and remove, it provides more convenient methods such as expire, exists, invalidate and much more. The implementation builds on the top of Akka actor system, it is completely non-blocking and asynchronous under the hood, though it also provides blocking APIs to ease the use. Furthermore, the library supports several configuration providers to let you easily use play-redis on localhost, Heroku, as well as on your premise.

getting a warn from play application when using OFormat to serialize case class

Asked 2019-Feb-26 at 09:33

I have a func where I use a play-json OFormat to serialize case class for api response, and now I notice some warn I get in the logs of the play app that looks like this:

The reason for the warning is the message serialization between Akka actors. It is not your "play-json and my serializer is just:".

You started to use play-redis and the plugin use Akka actors, and use the simplest serialization, the java serialization. It is slow so they recommend do not use it in the productions (that's why the warning exist), you need to change it in the settings.

QUESTION

Calculate % Processor Utilization in Redis

Asked 2017-Mar-24 at 00:42

Using INFO CPU command on Redis, I get the following values back (among other values):

used_cpu_sys:688.80

used_cpu_user:622.75

Based on my understanding, the value indicates the CPU time (expressed in seconds) accumulated since the launch of the Redis instance, as reported by the getrusage() call (source).

What I need to do is calculate the % CPU utilization based on these values. I looked extensively for an approach to do so but unfortunately couldn't find a way.

So my questions are:

Can we actually calculate the % CPU utilization based on these 2 values? If the answer is yes, then I would appreciate some pointers in that direction.
Do we need some extra data points for this calculation? If the answer is yes, I would appreciate if someone can tell me what those data points would be.

P.S. If this question should belong to Server Fault, please let me know and I will post it there (I wasn't 100% sure if it belongs here or there).

You need to read the value twice, calculate the delta, and divide by the time elapsed between the two reads. That should give you the cpu usage in % for that duration.
