I'm trying the Applications Manager to monitor remote routers, using the Ping Monitor. I've got a few router ip's added as monitors. 

Most the time they respond as up, but every day I will get emailed saying something is down. On the next ping/email alert (15mins time) it will generally be up.

Is there any options to say if it hasnt repsonded retry before marking the device as down, to stop these false reports.

Thanks in advance
