Nagios Support Forum

I am trying to create an availability report and have it email the PDF out to several associates. It emails out but if you look at the PDF attachment there is no data just the title. I click on the link to view in Nagios and it just spins and spins until finally it stops and displays nothing. Is it normal behavior for the reports to take a long time to generate? I still have my old Nagios Core box up and running and the availability reports that I am generating spit out the data in a few seconds. Is there a way to generate the reports under Nagios Core and make it default? I usually look at last month to send out the availability report to our Business Units. I liked the schedule and automatically email a generated PDF but if there is no data in the PDF than it won't work.

I'd like to help with this, but will need to gather a bit more information -
1. Can you provide a screenshot of what you're seeing in the PDF attachment?
2. Are you forcing SSL?
3. What is your program URL / external URL? (found under Admin -> System settings)
4. Can you post the output of top|head-17?

1. Attached image
2. Not sure about forcing SSL but I am using SSL.
3. Attached

Can you also run the following commands and show the output?
Have you tried using an IP address in the "Program URL" instead of a FQDN?

I did try the IP address but got this for the PDF report:
Not Found
The requested URL /reports/availability.php was not found on this server.
Apache/2.2.15 (CentOS) Server at <Nagios IP Address> Port 443

If you need or want the exact IP and hostname let me know where I can send them. Don't want to put that information out on a message board.

When you changed your Program URL was it to https://nagiosip/nagiosxi/?

Also, from the Nagios server, can you run the following -

PING nagiosl1p.ws.wsfgrp.net (IP Address) 56(84) bytes of data.
64 bytes from nagiosl1p.ws.wsfgrp.net (IP Address): icmp_seq=1 ttl=64 time=0.052 ms
64 bytes from nagiosl1p.ws.wsfgrp.net (IP Address): icmp_seq=2 ttl=64 time=0.036 ms

I used the FQDN - https://nagiosl1p.ws.wsfgrp.net/nagiosxi/

In the XI GUI, can you go in to Admin > System Settings and fill in the External URL to match the Program URL. Then see if you can email and / or access the reports after the change.
Let us know if this works for you.

No same thing a blank report both if sent by email or clicking the PDF icon. The csv versions appear to be working just not as user friendly.

Can you try setting your Program URL to https://nagiosxiip/nagiosxi/ ?
