Package: munin-plugins-core
Version: 2.0.6-4
Severity: normal

With mail notifications turned on, I frequently get these
notifications for latency on all devices:

To: munin
Subject: Munin notification weinberg

weinberg :: weinberg :: Disk latency per device :: Average latency for 
/dev/base/root
        WARNINGs: Write IO Wait time is -248.17 (outside range [0:1]).
        OKs: Read IO Wait time is 0.02.

I presume it's a wraparound, and 5 minutes later I get the clear
message.  Unfortunately, there are a lot of devices, so I get these
bogus notifications quite frequently.

Also, there seems to be missing documentation about how to configure
the warning threshold in plugins.conf.  I've tried various permutations of
[diskstats]
env.latency.*warning [-300:1] etc, but nothing has yet worked for me.
