Once only
: a single report will be sent, containing data logged up until the point when the
alarm occurred. This is useful for seeing what conditions led up the alarm.
By default, the report includes the entire last day (1440 minutes) of logged data, but you can
limit this (saving battery usage and mobile data allowance) by specifying how many minutes
to report in the “First report to include the last” field.
Note that this many minutes of data will be included in the alarm report, even if another
report containing some of the same data has already been sent.
Two Times
: two reports will be sent.
The first report is exactly the same as for a “Once only” report, containing data leading up to
the alarm for the specified period (1 day by default).
A followup report is then sent some minutes (specified by “Followup report delay”) after the
alarm is triggered. This second report only contains data logged since the alarm occurred.
This allows the user to see what happened for a window of time after the alarm was
triggered, without needing to wait for the next periodic/daily report.
Repeat (fast reporting)
: a series of reports will be sent.
Again, the first report is exactly the same as for a “Once only” report, containing data
leading up to the alarm for the specified period (1 day by default).
Followup reports are then sent at the rate specified by the “Fast Report Period” specified on
the
Change Report Settings
page (see below). Each of these reports only contains data
logged since the previous alarm report was sent.
Fast reporting continues until the alarm goes inactive or has been acknowledged, selectable
by the “Stop fast reporting when” dropdown.
Fast reporting allows the user to receive regular updates while an alarm condition is active,
so that the situation can be monitored as it unfolds.
NOTE:
Fast reporting is completely independent of fast logging. Either can be enabled
without the other. However, for the followup reports to include useful data, the logging
period must be less than or equal to the fast report period, so in practice it will usually make
sense to enable fast logging whenever fast reporting is used.
The alarm report format is configured in the Alarm Reports section in the
Change Report Settings
page (see 5.11 - Reports):
The alarm report options are:
Reports to send
: Whether alarm reports will be sent to the list of email addresses, either of
the FTP servers and/or the HTTP server (specified on the
Change Report Settings
page)
Email Subject
: This will appear as the subject of emails containing the alarm report
Fast Report Period
: How often repeat alarm reports should be sent out (only applies to
alarms with “fast reporting” enabled – see above)
