It would be really useful to have statistics on the number of errors and warnings in the RM and NM web UI. I'm thinking about - 1. The number of errors and warnings in the past 5 min/1 hour/12 hours/day 2. The top 'n'(20?) most common exceptions in the past 5 min/1 hour/12 hours/day By errors and warnings I'm referring to the log level. I suspect we can probably achieve this by writing a custom appender?(I'm open to suggestions on alternate mechanisms for implementing this). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
