The AutoPing Monitor saves you time and money by detecting the problem and doing it for you.
AutoPing monitors unreliable networking equipment, detects issues with network stability, and (as a bonus feature) can be used for proximity detection of wireless devices. This feature is built-in to all SynLink PDUs.
The feature works by sending periodic ping requests to devices on the network. When ping fails, the event is logged and immediate action can be taken like sending an email alert, switching an outlet, power cycling a group of outlets, or sending a custom API call to a 3rd party application.
We've found this feature to be advantageous in the following applications.
As smart devices get smarter, device lock-ups get more common. This is especially true in the IoT connected world we live in today.
In this example, AutoPing is configured to periodically check on a local device (smart TV) on the network.
The TV is connected to outlet #3 of a SynLink Switched Pro+ PDU. If the smart TV fails to respond to three ping requests from the PDU, the TV's outlet is power cycled and an email is sent to the Network Admin for immediate investigation
The AutoPing monitor continues to send ping requests in the background after the outlet has been power cycled expecting the TV to come back online. When the TV boots up and responds again, the AutoPing status is set back to an OK state and the cycle repeats.
Pro Tip #1: The Test Ping Diagnostic Tool can be used for remote debugging.
Especially useful when the PDU is the only device accessible on a remote network.
Pinging the gateway (router) to an external network is not always enough to detect a problem. Autoping can be set up to ping multiple IP addresses simultaneously.
An example where this might be useful is with the following network topology:
SynLink PDU <--> Managed Switch <--> Router Gateway <--> The Internet
In some failure modes, the router and switch may still respond to ping while in a locked-up state.
Solution: set up AutoPing to monitor the IP addresses of the managed switch, router, AND a device on an external network (Internet).
In this example, we chose to ping Google servers on the external network. It is assumed that something went wrong on the internal network if the AutoPing status on google.com becomes unreachable. The PDU attempts recovery by power cycling all networking equipment.
Pro Tip #2: This method is dependent on Google's servers staying up so choose your external ping device carefully.
When the problem was detected, the Networking Equipment outlet group was power cycled using the Outlet Grouping feature that's standard on all SynLink Switched PDUs. The group includes the router's outlet and the managed switch outlet. Outlet groups can be easily created using the SynLink web interface as shown below:
Automate turning on your office desk lamp and heater when you get to work and turning it off when you leave. Shout out our engineers for coming up with this one.
This is achieved by configuring AutoPing to check on your WIFI connected phone to detect when you have entered or left a physical location. When the phone makes a connection to WIFI (i.e. when you enter your office building), the PDU detect this with a successful ping response. When the phone disconnects from WIFI (i.e. when you leave the office), the PDU detects with a ping timeout.
*The detection feature is available on SynLink firmware v2.5.27 or newer.
Pro Tip #3: Make sure to set your phone to a static IP or assign a dhcp reservation on your router.
You will be redirected to the Automation overview page and should see the newly configured AutoPing event.
Status = OK means the device is actively responding to ping requests. If AutoPing Timeout occurs status will display Unreachable.
Pro Tip #4: Multiple actions can be set to the same event. For example, when ping fails, you can email yourself AND power cycle an outlet AND make an HTTP post request to a custom application.
Pro Tip #5: Check the event log to see a time-stamped history of events that were triggered and test your setup.
