reading default settings from gmond.conf

[dpocock]

It would be very useful to read all the default settings from the gmond.conf file if it can be found in one of the usual locations.

It may also be possible to inspect the list of open sockets of any running gmond process to discover configuration details.

Might it be even better for gmetric4j to be able to communicate through gmond on localhost (push metrics through gmond)?

@ngzhian Thanks for your initial work on this.

Did you have a look through the libconfuse source code? https://github.com/martinh/libconfuse

Just a few comments:

• could you do this work in a fork of the libconfuse repository so you can share the test cases?
• is there any parser framework you could use to keep the C and Java parser in sync?
• could you use any automated tool to quickly convert the C code to Java? As it is straight C and not C++, this shouldn't be too hard.

Please feel free to raise this on the libconfuse email list and CC me.

Yes I did briefly, I thought to rewrite the entire thing because the c
version relied on pointers. I will look at it more closely and attempt to
adhere to the c implementation as much as I can.
Also initially I wanted to use a Java parser generator such as javacc or
antlr, but that would introduce unnecessary dependencies for parsing such a
simple configuration file.
I think my next step is to fork the libconfuse to share the test case and
work on the Java translation.

Don't be deterred by the use of pointers.

If the parser generator adds runtime dependencies then it is not ideal. If it is only a compile-time dependency then it is OK.

@ngzhian Zhi An, did you make any progress on this task? If so, can you let me know where I can see the code?

[ngzhian]

@dpocock not much progress on this sorry!

FWIW https://github.com/addthis/metrics-reporter-config uses the local gmond.conf but does so rather a pile of regex hacks.
