Hi Support,

Please help:

I am using xi

My problem:
I never get host down alerts

I do get service down/unreachable/unknown alerts for these hosts.

### My host configuration ###
Check_Command: check-host-alive
$USER1$/check_icmp -H $HOSTADDRESS$ -w 10000.0,80% -c 15000.0,100% -p 5

I went to reports > under (Legacy Reports) clicked on Notifications and on that page I can see all hosts along with the type of notification mentioned.
For example I can see somehost1 with HOST UP - Time - Contact - Notification command( notify-host-by-email)
Similarly I can see somehost2 with HOST DOWN - Time - Contact - Notification command( notify-host-by-email)

Please suggest where I am wrong and how I can fix this issue.

Regarding you issue, It looks like notifications are beings sent but I believe the contact might not be getting the email.

For example I can see somehost1 with HOST UP - Time - Contact - Notification command( notify-host-by-email)
Similarly I can see somehost2 with HOST DOWN - Time - Contact - Notification command( notify-host-by-email)

If the the contact was added within XI, it may not have the right notification handler. You can check this by following the steps in the guide below.
