AutoPing
AutoPing can monitor a network device and perform a task if the device stops responding. It can also monitor a
group of devices, the task will be executed if none of the group members respond. The task is either a list of relays
to reboot or a script to execute.

Common AutoPing settings
Be sure to enable AutoPing operation by ticking the "Enable AutoPing" checkbox. Certain
reset procedures
may
turn it off automatically.
The following parameters are used for AutoPing operation:
• Time between pings: This is the time between each ping check of the IP address. 60 seconds should be
useful for most applications. If multiple AutoPings are in use, each IP will be checked in sequence. For
example, 2 autoping IPs and a setting of 60 seconds will cause each IP to be checked every 120 seconds.
• Ping failures before reboot: This sets the number of failed communication attempts that must be sequentially
detected before a task is executed. For example, when set to 5, the target system must fail to respond 5
times in a row before it is rebooted. Since occasional network overloads and missed packets can occur
during normal network operation, a number between 5 and 10 pings is recommended.
• Ping responses to enable autoping: To ensure a reliable connection, autoping will only be enabled after this
many successful pings. We do not recommend changing this (10 is default) unless you must configure your
controller before connecting it to the target devices.
• Times to attempt reboot: If you have an unreliable target device, limit the number of times it will be rebooted
by entering that value here. For example, entering 5 will execute the task up to 5 times before giving up.
• Device reboot delay: After rebooting a device with a cold-boot power-off, a waiting period should occur before
the IP address is re-checked by AutoPing. This delay allows the device to reboot. Windows and Linux servers
can force automatic file system checks which may take several minutes to complete. Enter a safe value here,
for example entering 600 would cause the power controller to start checking the server for normal operation
10 minutes after reboot. If a script is to be triggered, any delays contained in the code being executed should
be considered in determining the delay setting here so that the thread completes before the delay elapses.
This timer starts at the execution of the thread started.
