If its not collecting and persisting metrics, is it more of a glorified htop?
Wait, really? Why not? Storage is cheap. Do you use something else to get historical visibility into metrics?

Vector is for per-instance custom drilldowns. I gave a talk last year where I showed how they both fit together: http://www.brendangregg.com/blog/2014-09-27/from-clouds-to-r...

Yes, Atlas, which is also open source: http://techblog.netflix.com/2014/12/introducing-atlas-netfli... . Atlas monitors cloud-wide, and stores historical metrics at a one minute granularity. Vector is for per-instance custom drilldowns. I gave a talk last year where I showed how they both fit together: http://www.brendangregg.com/blog/2014-09-27/from-clouds-to-r...

#34I got down to you should be able to install PCP from binary packages made available by the PCP development team on: ftp.pcp.io and that threw up a red flag in my brain. Then I noticed that techblog.netflix.com doesn't redirect to https (and indeed can't serve https) (I use https://www.eff.org/HTTPS-EVERYWHERE and did not get content over https). The directions _I_ saw for building from source looked pretty innocuous,…
Happy to discuss your concerns. PCP 3.10 should be available on Ubuntu's official repo pretty soon too.
The techblog isn't using SSL, and the git pull url for PCP is using the git protocol which is also unauthenticated, rather than the authenticated https transport (ssh is only an option when user accounts make sense).
Someone's at a conference and follows the link over public wifi. They get the same page but with "here's how to get PCP: ftp evil.io or git clone git://git.evil.io/pcp" Even if the webpage were ssl-enabled so that an attacker can't rewrite the pcp.io links, an attacker or evil network operator could MITM git.pcp.io or ftp.pcp.io. (FTP?!)
Being in Ubuntu's repo doesn't make it safe if Ubuntu's maintainers have no (semi-)trustworthy way of getting the code.

#37Or if it's in-house, any info on whether they have, or might release it?
I see bootstrap-submenu.css mentioned, but not Bootstrap itself:

#38Stackdriver with pagerduty and I have 250,000 custom metrics being published and hundreds and hundreds of graphs on dozens of dashboards.
Although, I am looking at SignalFX to give even better version of this, but I manage nearly 1,000 machines with only a staff of four.

#39I just tried installing this on a test VPS. PCP went well, but whenever I tried to input a "hostname" in Vector's UI to get stats, it just kept telling me it couldn't connect and to check hostname, regardless of what I put in the box. PCP was available and of course ports open and whatnot. I'm not sure what the problem was, but that was a bit frustrating. It looks like a slick product otherwise, especially for a firs…

His concerns seem plain to me. Unauthenticated channels for software distribution or software installation instructions are bad.
