If we have 500 devices does it ping all devices at the same time and log the data? Or does it ping 1 device at a time and log it?

Q: We are looking into your product and would like some more information of how your ping monitor works If we have 500 devices does it ping all devices at the same time and log the data? Or does it ping 1 device at a time and log it?

A: One monitor should be created for each device (so there will be 500 PING monitors). Monitor polls the device periodically at certain interval (for PING monitor default is 30 seconds and may be decreased if needed).

One poll consists in sending up to 3 ICMP Request packets (pings). Once the ICMP Replay is received the response time is calculated and used as a current performance value for the monitor to be logged. So, the percentage of the packets lost is not calculated and not logged.

If ICMP Replay is not received after 3 requests sent, the poll attempt is considered unsuccesfull. IPHost has a parameter which specifies how may failed attempts should be done before turning the monitor to Down state (for the PING monitor one attempt is done by default).

So, IPHost pings all the devices at the same time, meaning that each device will be pinged independently in the configured rate.
