Monitoring Server Accessibility
You can monitor whether specific IT devices are alive by having the EMX
device 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.
EMX 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 EMX 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 204). An example is
available in Example: Ping Monitoring and SNMP Notifications (on
page 251).
