LAN Monitoring
Some computers are very important and should keep running 24 hour reliably,
such as the ones in the data center, servers running the businesses of one
company. They need to be monitored, if anything wrong happen the network
administrators should get the notice at the earliest time. Based on
connection
status detection, LanHelper's LAN monitoring feature is capable of
monitoring thousands of computers simultaneously. Once network connection
lost & restore or other status changing was detected,
network administrator will be immediately notified by e-mail, network
message, etc.
One computer has probably seven connection statues in the remote
administration tool LanHelper, which are
listed on the bottom of this page. To start LAN monitoring, first check the menu item
"Monitor Mode", then click "Refresh By IP" or "Refresh By Name".
Under monitor mode, connection status changing would trigger certain alert events. At present four events
are available. If connection status changed and current status is
"---", it will trigger "status changed to be off-line" event. If the
previous status is "---", and current connection status is "alive", "@!", "!@", "@*" or
"*@", it will trigger "status changed to be on-line" event. If pervious
status is "alive", and current connection status is "@!", "!@", "@*" or "*@", it will
trigger "Name or IP changed" event. "Any change" event includes
all connection status changes. If the value (let's say x) of Refresh Status option "consider
status changed if consecutive" is set to 1 (default value), the events
would be triggered immediately every time the connection status changed. If x greater
than 1, the events would be triggered only when the changed status
continuously appear x times.
While the events have been triggered, alert information would be sent out,
or some actions would be performed. For example, send network message or
e-mail to system administrator, perform Wake-On-LAN operation to power on
the powered-down computers,
perform shutdown operation to power off connected computers, etc.
