Debugging Trending

The TrendDebug Citect.ini parameter is provided to help you while logging and trending data.

Example:

[Trend]
TrendDebug=n

where n can be the combination of the following debug options:

• 1 - Logs the client, server, and redundancy message types and also the samples being written in the Trends Server from normal acquisition.
• 2 - Logs detailed information about the currently active backfill process, including the redundant samples written to the archive.
• 4 - Logs detailed information for the TrendSetTable functions.
• 7 - Logs trend activities.
• 8 - Logs the summary information only for the currently active backfill process.
• 16 - Logs to syslog.dat the client trend data.

These settings can be added together to have combinations of logging levels. For example

[Trend]
TrendDebug=6

logs the detailed backfill process and TrendSetTable functions.

These settings are read dynamically, meaning that you can change these settings while CitectSCADA is running and the changes will take effect from that point onwards.
