Issue:
Today our Data Collectors are showing inconsistent results in CA Performance Center.
We investigated the Data Aggregator and found one of the directories used for exporting data to be full -
/dev/mapper/vg01-optimda 49G 49G 0 100% /opt/IMDataAggregator
We found the files in /opt/IMDataAggregator/app/dto_error are filling up the /opt/IMDataAggregator .
New files are created about every 10 mins.
To fix, We deleted a bunch and now there's 15G available.
We searched the CA Performance Management documentation and support site looking for what the dto_error files are, we didn’t get any results.
Can you tell us what these files are and what they are used for?
More information, an example of the content of the files in the dto_error

Environment:
CAPM 3.x
Resolution:
When we copy data into vertica and it fails due to some issues with DR, it will move the dto files to ../dto_error -
You can delete anything in dto_error directory, as we failed to load it and will never try to reload it.
