8. Notes

8.1 Event log

♦LAN Monitoring Report

The LAN monitoring function defines the line status depending on the number of transmission packets and the number

of packet errors within a certain period. Thus, the LAN monitoring function may report a line fault or high line load only

in a temporary high line impedance state. If a normal state recovery is reported immediately, temporal high line

impedance may have occurred thus there is not any problem.

♦The monitoring event is not alerted

- The alert function is based on the event information registered in the event log of the system.

Thus, set the event log process on the event viewer to [Overwrite events as needed]. The monitoring event is not

alerted in the setting other than that.

- The event registered in the monitoring event tree on the setting tool of alert function (Alert Manager) is not alerted to

the manager if Alert Manager Main Service does not operate. Even when the service is operating, if the

enabled/disabled flag of each alerting ways is disabled, the event is not alerted.

The alert enabled/disabled flag is set by selecting [Base Setting] - [Report] Properties from [Setting] of Alert Manager.

Also the event occurred before Eventlog Service started at the time of system startup cannot be alerted.

- You can set the time to the shutdown by selecting [Base Setting] - [Other] on the setting tool of the alert function (Alert

Manager). The initial value is 20 seconds.

When you set smaller value than this, the alert may not be performed at the time of shutdown.

- When an alert failure occurs at the time of alerting of monitoring target event, an error message is logged in the event

log. If you newly log the error message which occurs at the time of alerting as a monitoring target event, the error at

the time of alerting will be alerted again.

As a result, large number of alerts will be sent when recovering the failure. This leads to the increase of system load

and the degradation of the performance. Do not register the events especially which are produced by the following

alert function services as the monitoring target.

Alert Manager ALIVE(S) Service

Alert Manager Main Service

Alert Manager Socket(S) Service
