Ping monitor

The Ping monitor tests the availability of a specific computer or device on the Internet. The default interval is set to 60 seconds.

ipMonitor measures the round trip time by sending an Internet Control Message Protocol (ICMP) echo request to the specified IP address, and then waiting for a valid UDP packet to be returned.

The test passes if the monitor receives a valid return packet within the required timeout period. The test fails if the monitor's specified timeout period expires.

The Ping Monitor tests the following:

  • The route between ipMonitor's host machine and an IP-enabled computer device
  • The target computer or device is able to respond
  • The packet makes the complete round trip within a specific number of seconds

The Ping monitor is often used as a dependency for a group of monitors. For example, a web application group could include a web server, SQL server, drive space, and a Ping monitor that monitors the availability of the server computer.

In this example, you could assign the Ping monitor as a dependency for the web application group. If problems occur with the server, this configuration would prevent you from receiving alerts for all the application monitors and resource monitors configured to watch the server computer. This process would minimize the number of alerts you receive and help you identify the source of the problem.
