Dashboard Issue

[ksafa]

I am attempting to create some dashboards with performance graphs. Some of these dashboards have a lot of elements in them and when I attempt to clone them it wipes out all my dashboard. Am i reaching some sort of limitation in regards to how many dashboards/dashlets one can have configured? I'm seeing the following errors in http error log:

There seem to be multiple errors:

Code: Select all

PHP Notice: unserialize(): Error at offset 65492 of 65535 bytes in /usr/local/nagiosxi/html/includes/utils-dashboards.inc.php 

^ That one indicates the dashboard failed to unserialize. Could be because of DB column type.

Code: Select all

PHP Notice: Undefined variable: home in /usr/local/nagiosxi/html/includes/utils-dashboards.inc.php 

^ That one indicates you don't have a home dashboard, which is sort of needed.

I have a home dashboard prior to attempting to clone. 1st clone attempt works then when i try to clone again it erases all my previous dashboards and just leaves home dashboard.

I think you may need to do the steps referenced in this post and not the following ones first.

The above is assuming dashboards are in a working state to begin with. If they are not you should make them so first including the home dashboard. If you need it, I can give you the SQL needed to restore default dashboards.

That resolved my issue.

Thanks

Glad to hear it has been resolved. Can we go ahead and lock the thread or did you have any follow up questions?

[ksafa]
