Not all files are collected

[bockjoo]

I installed the collector and Florida xrootd (4.9.1-1) was configured to report the detailed monitoring
to the installed collector.
But number of closed files per day is too small to be true:
(base) [coldhead@oo SummaryCollector]$ wc -l wlcg_record.log.2019-04-30_20
36220 wlcg_record.log.2019-04-30_20
Here wlcg_record.log.2019-04-30_20 is a one day worth of list of closed files collected using
xrootd-monitoring-collector (XMC).
I was expecting at least 100K closed files based on the xrootd log file record.
From the XMC log, I see a lot of these:
2019-05-06 23:33:26,146 - 29472 - DetailedCollector - ERROR - File close record from unknown UserID=0, SID=1556882878#128.227.221.226#39878
TypeError: cannot unpack non-iterable NoneType object
2019-05-06 23:33:26,146 - 29472 - DetailedCollector - ERROR - file to close not found. fileID: 257523, serverID: 1556882878#128.227.221.226#39878. close=fileClose(rectype=0, recFlag=2, recSize=80, fileID=257523, read=332, readv=19501343, write=0, ops=ops(read=1, readv=6, write=0, rsMin=3, rsMax=69, rsegs=159, rdMin=332, rdMax=332, rvMin=307447, rvMax=8943104, wrMin=0, wrMax=0))

Did I misconfigure something?
