Hi guys, can anyone tell how is it possible to collect all metrics from Linux and visualize them in windows OS? How to make a bridge or connection between Linux and Windows and what are the technologies to be used.

thx
Thanks for this list!
One of the best devops presentations out there. Good job Brendan! You're making the world a better place one step at a time.
Performance tuning is not dev ops. This is basic, fundamental systems administration.
@@rhugga hope that he knows what devops is nowadays...
Not surprised when he said he worked for Netflix. Makes sense that their hires are giving talks on using top as a measure of perf lol. Genius idea.
Thank you for a wonderful session, much appreciated. 👏

I'm troubleshooting a java performance issue at the moment and found this systematic method of analysis very useful. Thanks Brendan.
Nice vid, reinforced some topics for me and learned new stuff. Next time I’ll be more prepared for my Netflix interview 😅
This is amazing. true love for the bits and bytes
I like how you start off straight to the point when you said that when you are mentored by someone you basically eliminate what you dont need to know lol
Very Useful content, thank you Brendan
Very informative! keep going!
So clear and educational, thanks for sharing!
Hi guys, can anyone tell how is it possible to collect all metrics from Linux and visualize them in windows OS? How to make a bridge or connection between Linux and Windows and what are the technologies to be used.
Thanks Brendan :) You are awesome.
Thank you man, I will definitely copy yours methods
Which tools are used for monitoring network usage/performance of a process?
Hi Brendan,
You are not by any chance available for freelance performance trouble shooting projects?
You sir, are a legend.
Outstanding content. Very helpful
This is golden
brilliant
Thank you very much
Thank you!
OMG!! I really need it.
Excellent
fantastic !
Very useful thank you !
Perfection !!
"more than 80 characters is a sin in unix world" :):):) didnt know but yea, makes sence.
Norway
Good video :)
I'm speechless than you
they present linux but all of them use MacOS
unprepared and confused
thats why he is the head of the netflix system performance.
@@ManiBalajiCye lol. Their engineers just figured out that the top command shows performance. Bronze age is right around the corner.
wtf is this macintosh :(
too slow
Thank you!
