[collectd] Problem with java plugin

[Paulo Silva]

Hi,

I think I've found the problem.

After recompiling collectd with debug mode on I was able to notice some
difference between the data sent with and without the java plugin:

(with the java plugin:)
[2014-01-11 10:31:46] [debug] write_graphite plugin: [x.x.x.x]:2003 (tcp)
buf 946/1428 (66,2 %) "server.memory.memory-buffered 183586816,000000
1389436306
[2014-01-11 10:31:46] [debug] write_graphite plugin: [x.x.x.x]:2003 (tcp)
buf 1087/1428 (76,1 %) "server.memory.memory-free 5780836352,000000
1389436306
[2014-01-11 10:31:46] [debug] write_graphite plugin: [x.x.x.x]:2003 (tcp)
buf 1149/1428 (80,5 %) "server..memory.memory-cached 1248223232,000000
1389436306
[2014-01-11 10:31:46] [debug] write_graphite plugin: [x.x.x.x]:2003 (tcp)
buf 1288/1428 (90,2 %) "server.memory.memory-used 1144266752,000000
1389436306

(without the java plugin:)
[2014-01-11 10:33:32] [debug] write_graphite plugin: [x.x.x.x]:2003 (tcp)
buf 416/1428 (29.1 %) "server.memory.memory-buffered 183586816.000000
1389436412
[2014-01-11 10:33:32] [debug] write_graphite plugin: [x.x.x.x]:2003 (tcp)
buf 476/1428 (33.3 %) "server.memory.memory-used 1145851904.000000
1389436412
[2014-01-11 10:33:32] [debug] write_graphite plugin: [x.x.x.x]:2003 (tcp)
buf 538/1428 (37.7 %) "server.memory.memory-cached 1248362496.000000
1389436412
[2014-01-11 10:33:32] [debug] write_graphite plugin: [x.x.x.x]:2003 (tcp)
buf 598/1428 (41.9 %) "server.memory.memory-free 5779111936.000000
1389436412

So it seams that when I load the java plugin some of the other plugins
start using my locale setting to display numbers (I'm Portuguese and we use
"," instead of "." as a decimal mark) so I fixed the problem running this
before starting collectd:

unset LC_NUMERIC LANG

Should I open a bug report for this?
