 What was the output on the combo check page, during the outage?

 Purely a sort of FYI I guess...  not sure what was occurring but last Friday early hours the clusetrr had a bit of a tizz and both nodes had no mysqld running and so procs was not green on both nodes...  but the combo check remained green throughout..

intrigiingly the actual output on that combo check shows



(wp-vldyn-estrela.ports)||(wp-vldyn-rafeiro.ports) = (0-0-1)||(0-0-1) = 1
 <snip>

i.e. its all showing clear for the individual lines which are also separated where the hostname includes a hyphen...  is that all correct ?


I don't think so. From the manpage of combo.cfg:
"Note: If the expression involves hostnames with a character that is also an operator - e.g. if you have a host "t1-router-newyork.foo.com" with a dash in the hostname - then the operator-character must be escaped with a backslash '\' in the expression, or it will be interpreted as an operator. E.g. like this:
 nyc.conn = (t1\-router\-nyc.conn || backup\-router\-nyc.conn)"
That's why it thinks you have hostnames like "wp" and "vldyn". It's almost certainly not testing what you want it to be testing.
CheersJeremy
