installed the latest version with munin version 2.0.33 but most of the graphs ending ERROR like below

Same issue. Any update on this?

I was able to narrow it down to the haproxyng_be_sessions-<backend name>_queued parameter being the cause of it, but I don't know perl and munin enough to find the exact problem.
For me the acual RRD seems to be syntactically valid, as the rrdtool can fetch on it. Th data is 0 which should be valid.

rrdtool fetch proxy.internal-haproxyng_be_sessions-reader_queued-g.rrd AVERAGE

I have narrowed it down to this line:

monitoring-munin-haproxy/haproxyng

Line 670 in 2d09f30

negative => "${service}_queued",

The queued parameters are referenced wrong in the graph.
