HST01DB-HISTORY-DUMP <seconds> (default = 120) 2 minutes
HST02DB-HISTORY-DUMP <seconds> (default = 600) 10 minutes
HST03DB-HISTORY-DUMP <seconds> (default = 3600) 1 hour
HST04DB-HISTORY-DUMP <seconds> (default = 86400) 1 day
Specifies the amount of time (in seconds) for MOMI history windows.
MOMI initially writes history to the HST01DB file at the interval specified by HST01DB-HISTORY-DUMP. MOMI reads data from HST01DB and consolidates it into HST02DB at the interval specified by HST02DB-HISTORY-DUMP. This process is repeated for the other history files.
For example, using the default values, MOMI reads 10 minutes of history from the HST01DB file and writes the consolidated data into HST02DB. MOMI then reads 1 hour of history from HST02DB and writes the consolidated data into HST03DB. MOMI reads 1 day of history from HST03DB and writes the consolidated data into HST04DB. If a history file reaches capacity or no more disk space is available, the oldest data in the file is automatically deleted to free up space.
A value of zero (or less than an internal minimum) turns history dumping off for that file.
Values given for each history file should be progressively larger than the next and a multiple of the previous (i.e. follow the pattern as seen in the default values). History always starts with HST01DB, followed by HST02DB and so on.
The value entered here will effectively still be a multiple of the raw data collection time, which defaults to 10 seconds.
Examples:
hst01db-history-dump 30 = dump HST01DB every 30 secs
hst02db-history-dump 120 = dump HST01DB every 2 mins
