[ENG] 3.12. [DKSF 48.4 IU] What Notifications Has the Log File Got?
The page
of a web interface represents a device operation. In the log file events of a device are recorded in a chronological order. All
«LOG»
notifications of the log file are duplicated via SYSLOG protocol, if an IP address of the SYSLOG server is specified in the settings of a device.
A log file is located in a nonvolatile memory. There are approximately 220 - 350 last notifications stored in the memory. All notifications are rewritten
round, which means that the oldest notification in the log file is rewritten by a new one.
The first time tag in the log file is 01.01.70 Mon 00:00: 00.UTC. If there is an IP address of an NTP server specified in the settings, then a device will try
to get a precise time and in case of success it will synchronize its internal clock with a precise time. After synchronizing time, two records will appear in
the log file that represent a time lapse when adjusting a clock to a precise time. If time received when synchronizing with an NTP server is different from
the time of an internal clock for less than 5 minutes, the clock will not be adjusted. The pace of the internal clock is changed in the way to adjust internal
time with a precise time received from an NTP server in a certain amount of time. Due to this, there is no time lapse in the list of events in the log file,
which makes analyzing it easier.
General Events
Operation Start (Reboot) XXXX YYYY – is recorded into the log file when rebooting or turning a device on. XXXX is a model name of a device.
YYYY is a firmware version
.
, installed on a device
Adjusting......the Clock is recorded into the log file if a time
via an NTP protocol is more than 5 minutes different from the time set on the
received
internal clock. The notification is displayed in 2 lines. The first line represents a time tag before resetting the internal clock while the second line
represents a time tag right after resetting the internal clock.
Events from IO Lines
ION=Y XXXX – is recorded into the log file when a current logic level is being changed at the IO line (switching from the status «0» to the status «1»
and vice versa) when notifications from the IO line are enabled in the log file. N is a number of an IO line. Y is a current logic level of an IO line. XXXX
is a description of an IO line, specified by a user at the page of a web interface.
Events from Temperature Sensors

A is a lower limit of a temperature range in °C. BB – is an upper limit of a temperature range in °C.
