It's not Open Source, but the sysdig cloud dynamic topology map does pretty much what you describe https://sysdig.com/product/.

Yes, this currently emits to file or syslog and you need to take care of the alerting. Of course, this is the very initial release and we plan to improve it. If you have a specific need or idea, feel free to open an issue or let us know on the mailing list.

Frankly, I'd leave it as is - I (and I'm sure lots of other opers) already have some kind of central log collection that we can alert off. Nothing more frustrating than all the various monitoring systems each with their own unique take on alerting ;) Just imho of course.

off topic but I think interesting: Andy Tanenbaum is also the creator and maintainer of http://www.electoral-vote.com/, which I find to be one of best resources on american elections.

Thx for the reference. I had no idea. I presume it reflects Andy's biases (which is, of course, up to Andy)

  WRT Gov. Susana Martinez ....

  A good-looking Latina governor from a Western
  swing state  with a fiery conservative speaking
  style would be a good addition to any ticket.

  Comparisons will undoubtedly be  made to Sarah Palin,
  but Martinez is completely sane and is fluent in 
  two languages that Palin has little command of:
  Spanish and English.

Yes, when you drill down using the mouse you will get the relevant system calls, including the buffers if they are I/O reads and writes.

Also, sysdig and csysdig have pretty advanced system call capture and filtering functionality. See this link for an introduction https://github.com/draios/sysdig/wiki/Sysdig%20User%20Guide

Thanks for answering. Small suggestion - its kind of hard to find Github link. Perhaps make it more visible.

by the way, I can find a million alternative cloud based photo services, all with comparable features. On the other hand, there are very few desktop picture managers, especially on windows and linux.

One of the tool authors here. The answer is "it depends". We absolutely designed sysdig and csysdig to work on production systems. They both work by capturing system events, so their cpu usage depends on the number of system calls in the system. On machines with average workloads, I would expect csysdig's CPU usage to be comparable or slighly lower than htop. On machines that do a lot I/O, the CPU will probably be higher. Memeory usage is typically some tens of megabytes.

Yes, I did pre-warm the volumes before using them.

And yes, there are several interesting workloads that I didn't test, including read only and read+write. It's potential material for another blog post.
