Printing Log Disk Files
7–2
Headers displayed in the log screens in the Powermonitor Software are saved
to disk with the data log. This means log files printed via DOS include the
column labels describing the data listed in each column.
Data entries in log disk files are organized with the oldest data at the
beginning of the file, and the most recent data at the end of the file. Note
that this is opposite to the order in which log data is displayed on the screen
in the Powermonitor Software.
If an EVENT, MIN/MAX or SNAPSHOT LOG for a selected device has
previously been saved to a disk file, the Powermonitor Software will append
the new log data for that device to the end of the file. However, the
Powermonitor Software will first determine if there are any duplications of
events or snapshots between the current log and the previously stored log.
The Powermonitor Software will not store duplicates of the same event or
snapshot.
The Powermonitor Software will continue to append data to the end of
existing log files on disk each time the operator uses the SAVE DISK
function. For this reason, the operator may be required to occasionally
remove large log files from the hard disk to free up disk space.
Logs saved to disk can be displayed on the screen or printed to a printer
through DOS using standard TYPE or PRINT commands. For example, to
print an EVENT LOG file for a remote device with a UNIT ID of 3099, go to
the directory from which the Powermonitor Software was originally invoked,
then use the command:
PRINT EVNT3099.LOG
SNAPSHOT parameter data normally displayed by the Powermonitor
Software using three separate screens (ie. SNAPSHOT LOG Left, Center,
and Right) is saved to disk in one 14 parameter wide print format.
To allow SNAPSHOT LOG disk files to be printed in their intended full 14
parameter width, a 132 column printer set to COMPRESSED mode must be
used. If any other printer configuration is used, the printer will be forced to
wrap–around line segments, causing headers to be misaligned with data
columns, as rows of data become interleaved.
EVENT LOG and MIN/MAX disk files may be printed using a standard
80–column printer.
