How to solve high memory ram over than 70%?
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.
bro your screen is pure white, hard to see the youtube settings LOL, ty for video tho
Has this been stolen from Brendan Gregg?
He has already given the credits to Brendan Gregg in the description.
Relax, my friend!
Did you just steal screenshots from Brendon Gregg?
Couldn't even hide his username 'brendon' for a process 😂
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...
