[@ladnas3866]

How to solve high memory ram over than 70%?

[@srinik5758]

It means 2 things. Either memory has to be increased according to the needs. Or tuning/timing has to be done. After finding out which app/db/thing is using most memory. eg, if a DB is using most memory, then ask them to tune it or increase memory permanently to suit the need. Increasing swap space can help but it has limitations. Timing change means, if 2 big tasks are running at the same time they can be scheduled to run different times to reduce memory contention.

[@ashishsrivastava1791]

Hi, my perf data file is showing the data in different format, pls help me to read the logs

[@Sarang8988]

Did you just steal screenshots from Brendon Gregg? Couldn't even hide his username 'brendon' for a process 😂

[@TheNetworkViking]

He has already given credits to Brendon Gregg in the description :) Using the word "steal" without any check is a bit too harsh i guess...

[@wesg01]

Awesome!
