Nagios Fusion Host Group Dashlet

All,

I have a host group with 1,452 hosts and the dashlet is dropping the 4th digit...showing 452. I have deleted and re-added with the same results of 3 digits? I can view the same host group on the Nagios XI server and it shows the correct number of 1,452. Am i missing something...

I labbed this up and it's working properly on mine. What version of Fusion are you running?

Try running this command and then waiting 15 minutes for the data to rebuild:

Code: Select all

/usr/local/nagiosfusion/scripts/truncate_polled.php
Then logout of your account in Fusion, then re-login again.

Thanks for your reply...I tried the command and waited 15 minutes and have the same result. I am on version 4.1.7 for Fusion and 5.6.6 for Nagios XI.
In your lab did you create a host group that had over 1,400 hosts? The dashlet works fine on host counts under 4 digits for me.

Yes, I created 1850 hosts and added them to a single hostgroup, the number showed properly.

Do this, run this command as root on the fusion server and leave it running:

Code: Select all

tail -Fn0 /var/log/httpd/error_log /var/log/httpd/ssl_error_log
Then open the page that shows that dashlet and once it loads send us the full output of the still running tail command.

Is the user you logged into the Fusion web interface as an Admin on that XI server?

Please attach this file:

Code: Select all

/usr/local/nagiosfusion/html/includes/dashlets/hostgroup_summary/hostgroup_summary.php

Same as mine, I think we'll need to debug this on a remote session as the tables are pretty big.

Please create a ticket for this and include a link back to this forum thread so we can get a remote session setup:
