NAME:
sampler2log - sampler logger

SYNOPSIS:
sampler2log [-d delta][-n samples_per_file] [-t minutes_per_file][-m max_files][-v] device_managersampler

DESCRIPTION:
Sampler2log stores the monitor values from the specified sampler into a series of FITS binary files in the telescope's logging directories. The full path to each file is printed as it is opened. Each file accepts 3600 samples before being closed and the next file opened. The file name consists of the time of its first sample. Files continue being opened and filled as long as the program is running. If the device name is not specified or is illegal, then sampler2log returns a list of legal device names and exits. If only the device name is specified or the given manager name is illegal, then the program returns a list of possible manager names for that device and exits. If only the device and manager names are specified or the given sampler name is illegal, then the program returns a list of possible sampler names and exits.

OPTIONS:

-d delta	specifies the minimum elapsed time in seconds between samples. For example, if a sampler produces the sample every 200 msecs and delta is set to 1 then only every fifth sample will be written to the file; or if delta is set to 0 then every sample would be written to the file. The default is 0.
-n samples_per_file	sets the criterion of the size of the file by number of samples. The default is 3600.  Only one of the options or may be set.
-t minutes_per_file	sets the criterion for the size of each file by period. Only one of the options or may be set.
-m max_files	causes the program to exit after have been written.
-v	set verbose mode.

CAVEATS:
If a to-be-written file already exists, the program adds its process identifier (PID) to the new file's name.
