OpEvent Advanced regex: question

In opEvents, per Advanced, the search per regex is possible, on the bottom is noted:

*use "regex:[regular expression] for advanced filtering".

Now, I have here nodes, called worker[01-15]-*. I used the following regex:

regex: "([worker])" => shows all entries for all nodes in the selected time period

"([worker])" => no data to display

"^[worker]*$" => no data to display

Any tips?


thanks

      the regex:XYZ idiom in opevents' advanced search dialog refers to MongoDB's regex query operator, which supports perl-compatible regexps (aka PCRE - see this link for introduction to regular expressions).

      your use of '[]'  is misbehaving as it's meant for character classes. the 'regex:([worker])' happens to work more or less because it checks for 'an occurrence of any of the characters w, o, r, k, e or r anywhere'.

      i'd suggest something like 'regex:^worker-\d{2}-' if your node numbers are 0-padded, or 'regex:^worker-\d{1,2}-' if you have both "worker-4-something" and "worker-11-otherthing".
