Alfresco Search services does not show performance data

With Icinga 1 + PNP4Nagios 0.6.16 and using the python script,

The logs about the the following:

I think the problem is related with some float final presentation in perfdata of some integer values.
Although I'm not familiarized with python nagiosplugin library, I found that python script shows filter caches performance data at this way:

evictions=0.0c hitratio=100.0%;95:;90: hits=860.0c misses=0.0c size=1.0

while this format gives a correct graph (at least for hitratio and hits):

evictions=0c hitratio=100%;95:;90: hits=1001c misses=0c size=1c

I found this changing the corresponding line in the python script:

#self.metrics.insert(0, nagiosplugin.Metric(key, float(value), uom=uom, context=context))
self.metrics.insert(0, nagiosplugin.Metric(key, int(value), uom=uom, context=context))

But this is not straightfoward with the rest of metrics of type for example index or FTS.
