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..

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.
Cheers
Jeremy
