D. Set the maximum number of log files for the system to hold in memory using the
log_number command. If the logs in the storage directory exceed the maximum number
of logs then the oldest log will be deleted to ensure that there is room for new logs.
Default is 100 log files.
ATS-6501>log_number 4
OK
[OK] 2013-08-07T20:53:31Z
Note: Your data retrieval setup will need to take these values into account. The maximum
time the logs will be available on the system is the log_interval * log_files, in the examples
above that is 60 minutes. If you are not retrieving the files frequently enough you will lose
data.
E. Use the log_filename (user|timestamp) to set up the file naming scheme. Default is
timestamp.
a. When using the user file naming scheme you will also need to provide the file prefix,
the number of digits you would like to use as the unique file identifier, and the suffix
for the file.
ATS-6501>log_filename user Test 4 dat
[OK] 2013-08-07T20:53:45Z
File will be stored as: Test####dat, where the # is a sequence of 4 numbers and
characters to uniquely identify the file name.
Note: When the files are stored using the “user” option, the filename will not end
with a .gz extension even if the compression is turned on.
b. When using the timestamp file naming scheme the files are written out at the
log_interval setting and time stamped starting with the last two digits of the year, two
digit month, two digit day, two digit hour, and two digit minute when the log was
opened. Example (File 0810021530) log was opened 2 Oct 2008 at 15:30 (UTC).
This command will also accept an optional suffix to append to the filename (i.e. .nov
= 0810021530.nov).
ATS-6501>log_filename timestamp <suffix>
[OK] 2013-08-07T20:53:56Z
Warning: If the ATS-6501 is currently logging data and you change the file naming
convention you may wipe out any saved files stored in memory. Ensure these files
are downloaded prior to making any changes to prevent a possible loss of data.
F. If file compression is desired use the log_compression command and turn the
compression on (1) or off (0). Default is on (1)
ATS-6501>log_compression 0 (Compression=Off)
[OK] 2013-08-07T20:54:52Z
Note: When using compression in conjunction with the timestamp filename option the
file will end with the .gz file extension. User defined filenames will not have the .gz
