Various users were reporting problems with no performance graphs and no live data / updates in the Ui after clean installs of fifo. E.g. no % complete when importing datasets or MB uploaded when creating backups.
I also noticed that when users were posting screenshots etc often there would be a not connected icon in the top right corner of the Jingles ui.
I had a hunch it was hunter related and altho my install was on the latest version of chunter and jingles I decided to run the counter updates script on my nodes and see what would happen.
Immediately following a chunter update the same bug/issue was seen on my fifo, no graphs no live updates etc. I tried various things in troubleshooting. namely:
downgrading to earlier versions of chunter
restarting chunter and fifo services
clearning browser cache
removing hypervisor manually via fifoadm
Eventually the trick for that solved the issue was to perform the following actions in this sequence.
Downgrade jingles to fifo-jingles-0.6.1p2 from fifo-jingles-0.6.1p3
Restart fifo services
Manually remove hypervisors via "fifoadm hypervisors delete uuid"
Restart hunter on the nodes.
Following this above sequence graph and live updates immediately return.
These sequence/steps has been confirmed to resolve the issue for other users effected e.g. Digidaz with clean install.
It appears that something related to fifo-jingles-0.6.1p3 in combination with chunter is causing the issue.
