Monitor Host Up or Down State with Internet Control Message Protocol (ICMP) for a Device on Cisco OnPlus Portal
Event Monitors are mainly used to monitor the device in order to provide notifications to the technicians in a timely manner if there are any problems with the device performance. Testing in a network is done mainly to check the performance of the network. There are various tests which are available based on the monitors which are present in the device.
Internet Control Message Protocol (ICMP) is a protocol which is used to give feedback about the transmission of datagrams. The Host Up or Down State monitor is used to monitor whether the host is up or down with the help of the IPv4 ICMP echo requests. Only hosts which do not require a latency or loss performance measurements can use this monitor as it not give those measurements.
This article explains the steps of how to monitor Host Up or Down State with the help of ICMP on a device connected to the OnPlus and gives the test results. This monitor is for any connected device except the OnPlus Network Agent, such as security appliances, switches, and so on.
