Monitoring Server Accessibility
You can monitor whether specific IT devices are alive by having the Legrand PDU continuously ping them.
An IT device's successful response to the ping commands indicates that the IT device is still alive and can be
remotely accessed.
This function is especially useful when you are not located in an area with Internet connectivity.
Legrand PDU can monitor the accessibility of any IT device, such as database servers, remote
authentication servers, power distribution units (PDUs), and so on. It supports monitoring a maximum of 8
devices.
The default ping settings may not be suitable for monitoring devices that require high connection reliability so
it is strongly recommended that you should adjust the ping settings for optimal results.
Tip: To make the Legrand PDU automatically log, send notifications or perform other actions for any server
monitoring events, you can create event rules. See
Event Rules and Actions
(on page 184). An example is
available in
Example: Ping Monitoring and SNMP Notifications
(on page 222).
