Endgame Monk Help

Greetings everyone! First time POE player here and im looking for some general advice. i have a invoker lightning monk that ive leveled to endgame. have currently made my way to tier 10 maps- but sometimes struggle with getting oneshot/surviability issues. most builds i see people are running no lower than 2Kish health unless their ES is stacked. mine are both super low. my resistances are pretty much capped besides chaos, my evasion is almost 80%. clear and damage seem ok i suppose. but, so how do i get more health? is it a simple as more “max life” rolls on gear? anyone running monk who is breezing i would greatly appreciate some pointers! thanks in advance!
