● Otherwise, you are prompted to specify the file location and name. The default file name is store.zip. Change the
name to identify the system, controller, and date.
NOTE: The file must be uncompressed before the files it contains can be examined. The first file to examine for
diagnostic data is store_yyyy_mm_dd__hh_mm_ss.logs.
Viewing event information
If you are having a problem with the system, review the event log before calling technical support. Information shown in the
event log might enable you to resolve the problem.
To view the event log, in the footer, click the events panel and select Show Event List. The Event Log Viewer panel opens.
The panel shows a tabular view of the 1000 most recent events logged by either controller. All events are logged, regardless of
notification settings. For information about notification settings, see Setting system notification settings on page 48.
The event panel in the footer shows the numbers of the following types of events that the system has logged:
● Sev. One of the following severity icons:
○
Critical. A failure occurred that may cause a controller to shut down. Correct the problem immediately.
○ Error. A failure occurred that may affect data integrity or system stability. Correct the problem as soon as possible.
○ Warning. A problem occurred that may affect system stability but not data integrity. Evaluate the problem and
correct it if necessary.
○
Informational. A configuration or state change occurred, or a problem occurred that the system corrected. No
action is required.
○ Resolved. A condition that caused an event to be logged has been resolved. No action is required.
● Date/Time. The date and time when the event occurred, shown in the format year-month-day hour:minutes:seconds. Time
stamps have one-second granularity.
● ID. The event ID. The prefix A or B identifies the controller that logged the event.
● Code. An event code that helps you and support personnel diagnose problems.
● Message. Brief information about the event. Click the message to show or hide additional information and recommended
actions.
● Ctrl. The ID of the controller that logged the event.
Hover the cursor over the left side of this area to display the Critical & Error Event Information panel, which shows:
● The number of events with Critical and Error severity that have occurred in the past 24 hours or in the last 1000 events
● The date and time when the last most-severe event occurred
The
icon indicates that the panel has a menu. Click anywhere in the panel to display a menu to view the most recent 1000
events on Viewing the event log on page 143 and set up system notification settings on Setting system notification settings on
page 48.
When reviewing the event log, look for recent Critical, Error, or Warning events. For each, click the message to view additional
information and recommended actions. Follow the recommended actions to resolve the problems.
