[opennms-discuss] Waiting for availability data. One or more categories have never been updated.

[Dan S. <dan...@pr...>]

After working through a couple issues with the latest upgrade I was 
finally able to start OpenNMS and log in again. Now there is no data 
showing for any categories. I started reading through the log files and 
came across entries like this in the rtc.log:

2017-02-23 09:05:02,588 WARN  [DataSender-Thread-1-of-5]

The same message is shown for every category. I'm not sure where to look 
next. Any ideas would be appreciated.

Thanks,
Dan
