[rabbitmq-discuss] mnesia tables

[Alain Dazzi]

Hi,

I was wondering if anyone had a procedure to connect to running rabbitmq
node and
 read/extract mnesia records using erlang. For the lack of such tool, I use
grep to try to find stuck
messages in the various queues (cd /var/lib/rabbitmq/mnesia/...node.../ and
grep one of the queues).

Something like ... which seems to only show the schema table.

adazzi at cumulonimbus:~$ erl name node
Erlang R13B03 (erts-5.7.4) [source] [64-bit] [smp:8:8] [rq:8]
[async-threads:0] [hipe] [kernel-poll:false]

Eshell V5.7.4  (abort with ^G)
1> mnesia:start().
ok
2> mnesia:change_config (extra_db_nodes, [ 'node at cumlonimbus.dev.foo.com'
]).
{ok,[]}
3> mnesia:info().
