Hello,

please check the 'Settings'-tab of these Ping-Sensors. By default PRTG creates Ping-Sensors, with a ping count of '1'. Packet Loss can only be monitored with a higher ping count, so please enter for example '5' as ping count.
You could use the 'Multi-Edit' to change this for more than one Ping-Sensor at a time, if so please do it the following way:

  • in PRTGs web interface go to "Sensors"->"By Type"
  • select all sensors where you want to change this setting using the checkboxes
  • then use the 'Multi-Edit' (the little wrench in the upper right corner)
  • in the following tab please enter your chosen ping count
  • Click 'Continue'
    Best Regards.

Just a little tweak. I was looking for this for a week!

If I change the ping sensor to measure packet loss, at what point does the sensor error out and report a down state? Would it do this only at 100% packet loss?

I ask because I am having problems with SNMP sensors reporting down on the same device that the ping sensor is not (but where it does show higher than normal packet loss). What is the best way to deal with this?

Thanks.

John, please bear in mind, that Ping is ICMP and SNMP is UDP, usually these two protocols are treated differently and while one fails, the other might "still work". If you want an alarm already below 100 % packet loss (on the Ping Sensor), just set its Error Limit on the Packet Loss Channel accordingly.
