entries for each variable; the SSA7008 model can store the most recent 200 log entries for each variable.
You can also configure Alert to record log files on a remote server using NFS (Network File System). By
recording log files on an NFS server, there will be no limit on the number of entries stored in the log files.
To learn more about NFS logging, please see the section Logging Data on a NFS Server.
In Alert Firmware Image build 12 (Software Version 1.0.74) or higher, the logging and sensor update
intervals are now separate. With this enhancement, the sensor update rate is fixed at once every 10 seconds
to ensure quick detection of possible breach conditions, while the logging interval for each variable can be
configured. Users can configure this interval to increase the log files’ time span. For example, it you set
the logging interval to 9 minutes on a SSA7001, the appliance will store readings that span the last 10 days
as shown by the following calculation:
9 min x 1600 readings = 14400 min = 240 hours = 10 days
The following formula will calculate the logging interval required to achieve a specific span of time:
Logging interval = desired span in minutes ÷ log entry limit
where log entry limit is 1600 for SSA7001, 400 for SSA7004, and 200 for SSA7008.
To configure the logging interval for a particular Sensorsoft device use the following procedure and refer to
Figure 7a below:
1. Login to the Alert web interface as admin.
2. Click on the Administration hyperlink located on the left side of the Monitor List.
3. In the Port Settings table, locate the port number of the target Sensorsoft device, and then set the
corresponding Data Log Interval to the desired number of minutes.
