CIMPLICITY maintains several Logging tables that document data, alarm and event statistics, in addition to other processes such as SPC.
The System Sentry Logging screen enables you to see the total number of entries to the different log files.
Guidelines for using the Logging screen
include:
The Table Total is the total for all the
tables that exist within the computer that are being registered by
any Data Log Manager on that computer including Point Data Log,
Event Log and Alarm Log.
The Table Totals, including number
of Writes, Reads, Queue and Maintenance Actions
are the totals that have occurred since the project has been
running on the computer that is being monitored.
The gauge shows how many
Writes/Sec are actually
occurring.
Example
For Data Log, Writes/Sec keeps an average, how fast logging is occurring onto the Data Log table.
Note: When a queue overflow is
reported, it includes the number of overflows seen on this table
since the logger was started. This value may be used to assess the
correct setting for the DB_QUEUE_SIZE parameter.
