I'm looking for a library for gathering "runtime statistics" in python, by which I mean an interface for outputting structured log files. A good example of what I would like is Twitter's ostrich project in Scala, wherein one simply executes a statement notifying the logger of an event. Ideally, this would then be automatically aggregated into a suitable visualization for application monitoring.
Does anyone know if such a library exists? Alternatively, does anyone know a more generic way of combining traditional message logging with some simply graphing for runtime analytics?
Thanks!
Graphite is one such system, written in Python.
I'm not familiar with ostrich, but a quick look at the readme suggests that the python project mmstats might be close to what you're looking for.

I have a api made based on thrift TCompactProtocol.
Is there a quick way to convert it into TBinaryProtocolTransport?
Is there a tool for conversion?
FYI. My api is Line Api bases api Python.
There is no tool needed. Since yyou did not elaborate on your actual use case too much, I can only give a generic answer.
You control both RPC server & client + we do NOT talk about stored data
In that case you need only to replace the transports on both ends and you're pretty much done.
All other cases
You will need two pieces
a piece of code that deserializes old data stored with "compact"
a piece of code that deserializes these data using "binary"
Both cases are not really hard to implement technically.

Where can one find a manual to Quickly, where it is written about using (=programming, how to connect widgets in PreferencesDialogWindow with preferences, and how to use them in the application) application preferences? Official tutorial (both in "quickly tutorial" and here) tells nothing about it, although it is a very important aspect (they both are very short in general...).
(I mean the standard ubuntu-application template)
I tried to ask it on AskUbuntu, but didn't get an answer, so I hope to get a response here.
Maybe it would be easier for someone to just tell how it works, than point out a guide, in this case you are welcome!
I think Quickly's documentation should have what you're looking for. If not, maybe you'll find it in this tutorial.

Real-time api browser websites like ruby-docs.com and jqapi.com are very useful, it there any similar website for Python?
Updated:
By real-time I means instant search. docs.python.org is well-wriiten but a little hard for searching (comparing with ruby-docs.com and jqapi.co).
Not clear what you mean by real-time API in this respect, a Python API?.
The documentatation at http://docs.python.org is very useful and complete, supports multiple version of the Python language (starting with 2.6) and has search.
The search there is not as interactive e.g. the one on ruby-docs.com.
I use docs.python.org quite often and personally do not miss that interactivity, as my IDE for Python has a better interactive information than a website can provide.

I am intersted in building some text based GUIs, things that look like the terminal, but has functions like selecting rows and performing actions.
You know, things like htop and atop, ex:
Any resource on that?
You need Uwrid - a console user interface library for Python.
Documentation available on the website.
There is also Curses, which is in the Python standard library.
don't miss http://pythondialog.sourceforge.net/ also
Also, the library panwid offers a data table widget for Urwid, which does a lot of the heavy-lifting for an htop-like interface.

Someone could point out sites/books where I can find introductory documentation about the architecture of the Python VM?
I'm interested in the C version, but if there are easy-to-follow references about other implementations it could be helpful too.
I'm trying to find any kind of resources of higher level than plain source code (however, UML diagrams or something like that would be nice) And also, information about the design decisions involved, including tradeoffs between the different factors (performance, stability, simplicity).
You should be able to find the information you need at https://github.com/python/cpython/blob/HEAD/Python/ceval.c
If that's too low level for you, try
