Probable Causes
Invalid Values of Monit-
oring Data
Cause — The value "-4" indicates that Performance Monitor failed to obtain
monitoring data.
Reasons:
•
If the monitoring period for data with the export tool, does not match the col-
lecting period, the export tool cannot collect the monitoring data.
•
If data of SVP is updated while the monitoring data is being collected, data
collected near the start time is - 4.
The monitoring data in
the CSV file includes "-4".
Cause — When the CU number is not the monitoring target, the value "-5" indicates
that Performance Monitor failed to obtain monitoring data.
Reason — If the PG, LDEV, LU, RCLU, RCLDEV, URLU, or URLDEV operand is
specified, the value of the monitoring data is "-5". If the monitoring target is not
a CU, you must specify a CU as the monitoring target. You cannot use the export
tool but can use the Monitoring Options window of Performance Monitor when
specifying a CU as a monitoring target. For details, see “
” on page 52, and
If the RemoteCopy, UniversalReplicator, or URJNL operand is specified, the value
"-5" is not output in the monitoring data though the CU number is not the monitoring
target. In this case, data on monitored CUs are summed up and output into the
CSV file.
The monitoring data in
the CSV file includes "-5".
Cause — The value "-7" indicates that Performance Monitor failed to obtain
monitoring data.
Reason — If you added the CU during monitoring, specified longrange as the
gathering interval, and collected monitoring data, the value "-7" is displayed as
the monitoring data before the CU was added.
The monitoring data in
the CSV file includes "-7".
