[Pkg-nagios-devel] Bug#685457: nsca: Incompatibility between munin and nsca-2.9.1

[Xiwen Cheng]

Package: nsca
Version: 2.9.1-2
Severity: important

Dear Maintainer,

The input format generated by munin (2.0.1-1) is not accepted by
`send_nsca` when multiple results are chained in a single stream. The 
input stream is parsed incorrectly because of the recent addition:

> When submitting multiple simultaneous results, separate each set with
> the ETB character (^W or 0x17)

However munin isn't aware of this change. 

I don't see why this format change was introduced. It is not needed
and it breaks compatibility. 
I strongly believe the format should be reverted such that munin 2 and 
earlier (probably other tools/systems also) remain compatible. 

An extremely dirty workaround is use `tr` to substitute all occurences
of \n with ETB prior to sending to `send_nsca`:

> /etc/munin/munin.conf
contact.nagios.command tr '\n' '\27' | /usr/sbin/send_nsca
nagios.host.example -c /etc/send_nsca.cfg

Kind regards,
Xiwen
