The Ping Monitor sends out a typical ICMP 'ping' message to the specified host as often as is specified by the Schedule button. If the host doesn't respond before the given timeout value, the configured actions are fired.
The host name is resolved each time the ping happens which allows this monitor to also watch DNS servers. The time to resolve an address is not counted towards the total ping timeout.
Ping result times are recorded for report generation. If a ping response is never returned, a time of 30,000 is used to indicate the failure in reports. The Uptime Report is very useful with Ping data.
Many system administrators only want to be alerted after a few ping responses are missed. Configure that under the Alert Suppression setting in Advanced Options.
The Ping Server monitor can create reports based on the ping response from the target server/device. This data can be charted as well as output in .CSV or HTML tabular form. In addition, you can define what 'up' means and create an uptime report showing a percentage of uptime over a given time period.
