Best open source tools to performance tune front end and back end application in java technology
I need to performance tune front end application running in node js ,d3 js , html , javascript , css with express server and with back end in war file done in sbt deployed on tomcat using spark scala mongdb hive kafka mysql hadoop. Let me know the best tools to monitor and performance tune the app for speed , good response etc., Thank you in advance.
You're talking about many technologies + there's only ever one performance bottleneck disk i/o + usually only write i/o as read i/o normally comes from file buffers managed in Kernel memory or database buffers managed by the database daemon, like MariaDB/MySQL.
So performance tuning occurs like this.
1) Database design must be done by someone who understands how to design high speed, scalable database systems.
2) If system is swapping (check top), add memory till swapping stops.
3) If MariaDB/MySQL requires more memory or tuning (use mysqltuner), then add more memory + roll in tuning suggested by mysqltuner.
4) If you aren't using database replication, disable replication completely (normally a huge speed increase).
5) If you have UPS units attached to your machine hardware, tune MariaDB/MySQL to use aggressive caching.
6) Enable logging of missing indexes + slow queries, then fix all reported problems.
Tip: Tech like Javascript runs at memory speed. Databases performance throttles by disk writes. The other questions your asking, like hadoop have completely different answers. Best to open one question/technology where you have a question, then provide an example of your code + specific slow down you're trying to fix.
Tip: Using complex tech like MariaDB/MySQL/HADoop require correct initial design. When data structures related to these are designed poorly, performance will circle the drain quickly + the only real fix is a redesign. Best focus on correct design in the beginning.

I think something which might suit your needs is the "Apache JMeter application". You may refer to the link below for more information. Otherwise, your solution should look similar or provide similar functions also capable in "Apache JMeter application".
