[ENG] 3.11. [DKSF 70/71.6 IU] System Log of a Device

The page «Log» of a device web interface represents a device operation. All events are saved in the log in a chronologic order. All notifications of the log are duplicated via SYSLOG protocol if an IP address of SYSLOG server is specified in the settings of a device.

The first time tag in the log is 01.01.70 Mon 00:00: 00.UTC. If an IP address of an NTP server is specified in the settings, a device will try to receive a precise time. If successful, a device will synchronize its internal clock with a precise time. After a time is synchronized in the log, two entries appear that represent a time jump when setting the clock correctly. If the time received when synchronising with an NTP server is different from the time of an internal clock for less than 5 min, its clock is not reset. The pace of internal clock is changed in the way for an internal time to coincide with a precise time received from an NTP server after a while. Therefore, there is no time jumps in the events list in a log, which makes analysing it easier.

General Events

Operation Start (Reboot) – is written into the log when a device is turned on.

Clock Reset – is written into the log if a received time from an NTP server is different from an internal time for more than 5 min. The entry is displayed in two rows: the first row has a time tag before resetting an internal clock, and the second one is made just after a reset is made.

Events from Temperature Sensors

Thermo chan.N "XXXX":normal YYC – is recorded into the log if a mode of sending SNMP TRAP notifications from temperature sensors is configured, and a temperature on a temperature sensor is within the limits set by a user. YY – is a current temperature on a temperature sensor.

Thermo chan.N "XXXX": above normal YYC – is recorded into the log if a mode of sending SNMP TRAP notifications from temperature sensors is configured and a temperature on a temperature sensor is above the upper threshold, set by a user. N – is a number of a temperature sensor. XXXX – is a description of a temperature sensor, specified by a user at the page of a web interface. YY – is a current temperature on a temperature sensor.

Thermo chan.N "XXXX": below normal YYC – is recorded into the log if a mode of sending SNMP TRAP notifications from temperature sensors is configured and a temperature on a temperature sensor is below the lower threshold, specified by a user. N – is a number of a temperature sensor. XXXX – is a description of a temperature sensor, specified by a user at the page of a web interface. YY – is a current temperature on a temperature sensor.

Thermo chan.N "XXXX": failure – is recorded into the log if a mode of sending SNMP TRAP notifications from temperature sensors is configured and a temperature sensor does not respond (is not connected). N – is a number of a temperature sensor. XXXX – is a description of a temperature sensor, specified by a user at the page of a web interface. When a sensor operation is restored, a notification about a status of a temperature range is sent (see above).

Events from IO Lines

Input/output: line N "XXXX": 0->1 – is recorded into the log if a mode of sending SNMP TRAP notifications from IO lines is configured, and an IO line has switched from the status «0» to the status «1». N – is a number of an IO line. XXXX – is a description of an IO line, specified by a user at the page of a web interface.

Input/output: line N "XXXX": 1->0 – is recorded into the log if a mode of sending SNMP TRAP notifications from IO lines is configured and an IO line has switched from the status «1» to the status «0». N – is a number 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 the «Watchdog» Module

Watchdog: resetting chan.N "XXXX". A (IPAYYYY, B (IPBYYYY, C (IPCYYYY – is recorded into the log when the Watchdog is triggered. N – is a number of a power management channel. XXXX – is a description of a power management channel, specified by a user at the page of a web interface. IPA, IPB, IPC – are IP addresses, specified in the settings of the «Watchdog».YYYY – is a status of corresponding requested IP address. It may be: responds, silent, ignores.

Watchdog: chan.N "XXXX". - a limit of repeated resets is reached (Y). Resets are paused. – is recorded into the log if a limit of consequent resets of a connected device is reached in the operating mode «Watchdog». N – is a number of a power management channel. XXXX - is a description of a power management channel, specified by a user at the page of a web interface.Y – is an amount of consequent resets of a connected device that has been performed.

Watchdog: chan.N "XXXX" reset. - a response is received. Resetting pause is over.

SYSLOG Support

All notifications in the log are duplicated by sending notifications via SYSLOG protocol if addresses of SYSLOG server are specified in the settings of a device at the page «Setup» of a web interface.

SYSLOG server is convenient to use for centralized collecting of notifications about events that take place at numerous devices and computers, operating in the network, particularly about the events at Netping devices.
