[collectd] key value in config does not support slash or back slash

[Zhihua Wen]

Hi, I am writing a new plugin for collectd, in my config, I want to add
some predefined common labels like the following, however, it seems the
config parser for collectd does not support back slash. I also tried to
quote the key value but the parser doesn't like quote either, is it
required for oconfig_item_t.key to contain only letter and digit? Is there
a workaround to this problem? thanks a lot.


<Plugin "write_monarch">
  <Label>
    www.example.com/location "us-central1-a"
    www.example.com/resource_id "123456789"
    www.example.com/resource_type "instance"
  </Label>
</Plugin>
