Rudimentary filtering already exists on the "interactive" port: 8652. See this thread for details on the current implementation: http://www.mail-archive.com/[EMAIL PROTECTED]/msg03619.html Basically, you can restrict the output by /cluster, /cluster/host, and /cluster/host/metric. However, you cannot currently query for "cpu_user" from all hosts (yet). There was some discussion at the recent meet-up about extending this somewhat. -- Jesse Becker GPG Fingerprint -- BD00 7AA4 4483 AFCC 82D0 2720 0083 0931 9A2B 06A2 ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
