Gauge dashlets disappeared

[bbackstrom]

We created a dashboard with several different gauge dashlets to measure response for certain pages of a web site. Some of the gauges (not all) suddenly stopped appearing, even though the placeholder is there when you hover in the area. What could have happened?

Hello, @bbackstrom. Have you updated XI recently? What version of XI is that? If you have google chrome right click on the placeholder, choose the Developers Console and look for the errors.

[bbackstrom]

We have not updated recently, no (though we plan to). This is version Nagios XI 5.4.13. I logged in with Chrome but when I right click on any of the placeholders I do not get a menu option for developers console.

[bbackstrom]

I think I found the console by selecting 'inspect element'. Will see what information is there.

@bbackstrom, Here's how to access it.

@bbackstrom, How long have you had the Mod Security on this server? Is this something you implemented just recently?

[Thu Nov 08 17:00:39.230422 2018] [:error] [pid 15139] [client 127.0.0.1] ModSecurity: Access allowed (phase 1). Pattern match "^127\\\\.0\\\\.0\\\\.1$" at REMOTE_ADDR.

Perhaps its blocking JQuery acess to the CDN repo?

[bbackstrom]

I am not sure on that. Will ask internally. Thank you.

[npolovenko]

@bbackstrom, Sounds good. Basically, I'd like to know if that or anything else on the network could be blocking the access to jquery CDN. And what kind of changes were done to this XI server during the past few days before these dashlets broke? Thank you!

[bbackstrom]

We discovered a change was made to a script workflow which caused a rename. We suspect this is the root cause and will have to add back the gauges. Thanks for the help!
