[rabbitmq-discuss] RabbitMQ 3.1.0 HTTP API rates are always zero

Mon Jun 3 11:24:46 BST 2013

Hmm, not sure I can say much more than "works for me".

The numbers that are shown in the web UI are taken from the request 
http://xxx:15672/api/overview (albeit without the ?columns= parameter); 
there is only one source for these numbers.

One thing you might want to check is if you are using a different user 
for web UI vs nagios. Users that do not have the "administrator" or 
"monitoring" tags will only see message rates for vhosts they have 
access to - could you be seeing that?

Another possibility (and I know this might sound patronising, but we all 
make mistakes) - are you talking to the same server in each case?

Cheers, Simon
