When the Gateway is unable to keep up with the polling interval for a device, a Device Communication Alert warning alarm is generated. The alarm message is <device name> is responding slowly to polling.
The Device Communication Alert alarm is generated after five consecutive polls exceed the polling interval. The alarm clears after five consecutive polls complete within the polling interval.
You can do one or more of the following:
Reduce the number of devices the Gateway is polling at 1 minute (Gateway 1.13 and newer).
Reduce the number of devices the Gateway is polling.
Add more CPU and memory to the Gateway.
Investigate network latency issues, or put the Gateway on the same local area network (LAN) as the device.
