The final checkbox on this page is "Automatically Refresh Page" If checked, the
alarms page will automatically refresh itself with the up to date status from the
recorder approximately once per minute. This saves having to constantly refresh
the page manually to see if any new alarms have arisen.
4.8.2. Alert History
The alert history provides a detailed account of all alerts and alarms on the
recorder. This screen is primarily used for diagnostic purposes. Alerts that are
currently active alarm conditions will appear in bold on this page. For a detailed
description of alerts see appendix I.
The fields displayed for each Alert in the history are:
Time
: The Date and Time the Alert or Alarm occurred. This information is
displayed using your time zone information as configured currently.
Alert Code
: Every alert occurrence has an Alert Code which can be cross
referenced with the information on the Alert Codes page
Alert Text
: This is the corresponding text for the alert code with the specifics
about the alert occurrence substituted in for the place holders in the Alert
Code's text
Severity
: The relative severity for this alert code as configured on the Alert
codes Page. Note that for alarms and other active alerts, you will see a separate
entry in the alert history for when the alarm was resolved.
4.8.3. Alert Codes
Every unique alert and alarm the NexLog system is capable of generating has an
alert code. The Alert Codes Setup page allows the user to view all of the possible
Alert Codes and set options for each one, such as whether or not the alert
should generate an email when it occurs. The Alert codes Setup page will
display a table showing one available alert code on each row. At the bottom of
the page are buttons for "Next Page" "Previous Page" and "Edit Alert". The Next
and Previous buttons allow the user to navigate through all the available pages
of alert codes as there are too many to fit on a single page. To edit the settings
for an alert, first highlight the alert code by clicking on it and then click the 'Edit
Alert' button.
Each alert code will display the code number for the alert, followed by its textual
description. In the description you will see placeholders that look like <~1~>.
These are filled in with the details of a specific alert occurrence when the alert
triggers and gets inserted into the alert history table. Finally, the severity is an
indication of how serious of an error the alert represents. These range from
'INFO' meaning it’s simply an informative alert, to 'SEVERE' meaning that the
alert condition should be addressed immediately. Each alert code is
preconfigured with a reasonable severity for each alert code, but you can use the
