SM2 reports
DISK FILE report
Monitoring information
READ
Number of read operations per second
WRITE
Number of write operations per second
FILENAME
Name of the monitored file.
The first row always contains the value *OVERRUNS. This entry
includes all input/output operations that could not be assigned to a
file entry because the internal SM2 table was full during the
monitoring cycle. It is generally set to zero or to a low value.
In the FILENAME column, not all names are in the format:
<catid>:<$userid>.<filename>. In the case of special disk accesses
(e.g. by DAB), this format is not applied.
MN
Mnemonic device name of the monitored disk device
VSN
VSN of the monitored disk device
