CMM does not record data

[[Ma...]]

I wonder if somebody could help me with an issue with recording data in CMMObserver.
I use simple script for downloading data from CMMObserver\ProgramDurationRecord.XML. Problem is that we have 3 identical machines with identical versions of Calypso and result is bellow:
Machine 1 - does not collect any data at all
Machine 2 - does not collect data from 14.08.2024
Machine 3 - does not collect data from 04.09.2024

Does anybody know what to check/do to run recording again?

Thanks in advance

Do these CMM's stay on 24/7? Have you tried re-booting Calypso? Or even the CMM.

Yes, they run 24/4. I tried several times with no change.

check amount of free space on disc and permissions?

Can you edit that file in notepad and save it? If not, then some process is holding it ( permissions )

I made a change and saved. No problem with this. Strange is that from one of CMM it does not record at all. There is only header:

<PartProgramsDurationRecord xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<ProgramsDurationRecord/>
</PartProgramsDurationRecord>

Monitoring Start/Stop was off. I activated it but after 3 days of running, no change.
