How to monitor cas's clustering.

[Toby Archer]

We are having intermittent issues with our CAS deployment where it seems the clustering breaks down. I've been trying to find a way to even look at the problem but have not had any luck all day. Mainly I've tried to get my computer into the hazelcast group through various methods to no avail. I started searching around on this mailing list and I ran across this post:

https://groups.google.com/a/apereo.org/forum/#!searchin/cas-user/hazelcast$20monitor|sort:date/cas-user/9XjQUU5xhwk/QVeKYr1hGAAJ

Which lead me here:

https://apereo.github.io/cas/5.0.x/installation/Monitoring-Statistics.html

and then:

https://apereo.github.io/cas/5.0.x/installation/Configuration-Properties.html

Which I haven't managed to get working. see this gist to see how I configured it if you have any ideas what I did wrong.

Anyway. I'm not having any luck getting any diagnostics tools working. Any suggestions on how I can get some insight into the clustering?

Hi Toby,

Seems like you are using 5.0.x from the documentation cited by you, but if not and you are using 5.3.x, you might want to read this, maybe related: https://groups.google.com/a/apereo.org/forum/?nomobile=true#!topic/cas-user/htBkshVVaFg

Other than that, I have no idea too with the information provided, maybe other can help?

oops. Yea, I'm actually running 5.2.7. I frequently forget to make sure I'm using the right version of the documentation after I've searched my way to it. I've updated the gist with the settings that the 5.2.x docs recommend, but all i'm getting is 401 "Access Denied You do not have permission to view this page." I press the "login again" button but to no avail. I can't seem to get the security on the dashboard to co-operate.
