Overview

The Message History provides a tabular view of the CSS message log. It lists events from the alarm system as well as other CSS applications, identified by a Message TYPE. You can open the Message History View via the menu item
CSS/Alarm/Message History

Message History

Properties

Each Message has several Properties, depending on the message type.

Per default, messages are listed by time, but you can sort on any Property by clicking the corresponding column header. Click again to sort in the "other" direction (ascending, descending).

If you double-click a Message, the "Properties" View will display all the Properties of a Message, including those that might not be listed in the table.

Explanation of most Properties:

Setting Start/End Time and Filter

By clicking the "Times" button, a dialog will allow you to specify the start and end time of the displayed message history.

Note that there is an internal limit to the amount of messages retrieved from the database to prevent excessive memory consumption: There might be more messages between the last displayed message and the selected "end" time!

By clicking the "Filter" button, you can set the rule in filtering the messages you are interested in. You can select the property and set its desired value. There are up to five properties you can set. The value patterns support SQL wildcards '%, '_'.

For example, filtering on TYPE="alarm" and NAME="%Vac%" will show only alarm messages for PVs with "Vac" in their name for the selected time range.

Preference Settings

Preference settings determine where the message history is obtained and how it is displayed. The preferences configuration panel can be opened via the menu
CSS/Preferences...,
then navigating to
CSS Applications/Alarm/Message History.
