Yeah. It annoys me that I had to do it this way, but I thought it was preferable to dragging all of the data out of the database to do it in php.

The code which builds the alert checker associations uses a MySQL query, so the regexp syntax you need to use in that box is limited to what MySQL can handle (which is not as powerful as the PCRE standard, of course). From the match_device_entities() function in <root>/includes/alerts.inc.php, line 724 (r8181, we use the stable branch):
case 'notregexp': case 'notregex': case '!regexp': case '!regex': $sql .= ' AND IFNULL(`' . $attrib['attrib'] . '`, "") NOT REGEXP ?'; $param[] = $attrib['value']; break;The code which actually tests the checker conditions, on the other hand, uses PHP's preg_match() function (within the test_condition() function, line 512 of the same alerts.inc.php file on my install), so you can use PCRE standard regexes in those (though there isn't as much of a need for anything terribly complex for the conditions itself, I would imagine.)
Hope that helps!

No, that didn't work either...
^\d.* also didn't help, just in case
Meh. Initial problem solved, but maybe it's not going to go so well
with more complex regex syntax.

Did you try ^\d.* ?

Though I can't figure out why the others aren't working (even
^\d.*).
Does the interface choke on the backslashes?

I'm having trouble making a fairly basic regex string match in
the
alerting system.
I want to not match any devices that have hostnames starting with
a
digit.
Easy, right.
I think my problem is not finding the right bracing to build the
syntax
within the ui.
Things I have tried that don't seem to work:
hostname notregexp \b\d.* hostname notregexp /\b\d.*/ hostname notregexp /(\b\d.*)/ hostname notregexp '/\b\d.*/' hostname notregexp "\b\d.*" hostname notregexp "/\b\d.*/" hostname notregexp '\b\d.*'
Has anybody figured out what the secret handshake is?
