regexps fixed for collectd 5.x

[underley]

Collectd 5.x graphite_writer plugin produces metrics like:
collectd.host-1.memory.memory-buffered
collectd.host-1.df-root.df_complex-reserved
collectd.host-1.disk-dm-0.disk_octets.write
Original regexps doesn't match such metrics.

This works for us on our pre-deployment environment. What's stopping it from being merged?

[Dieterbe]

whoops, i somehow forgot about this one.

[Dieterbe]

hmm pretty sure we use collectd 5.4.0,
our cpu metrics look like server.cpu.num.cpu.idle. same for interface, memory etc.

[underley]

collectd 5.1 from debian wheezy:
collectd.server-name.cpu-1.cpu-user

[X-Trade]

Yeah, that's how it is for us too.

Looks to me like this plugin handles both though?

[underley]

exactly

[Dieterbe]

I think we should introduce a new unit for this, like Irq

[Dieterbe]

also using the phrase "fixes for collectd 5.x" is not really accurate, since apparantly it's only for older versions of 5.x (as they work for collectd 5.4)

[Dieterbe]

Ping? If the things I mentioned could be fixed, that would make a nice PR.
