The Cricket folks have excellent spike-removal technology (now, if we could only prevent the damn spikes from happening in the first place). Please see the Cricket contrib page at: http://www.certaintysolutions.com/tech-advice/cricket-contrib/ You'll be interested in these two programs: killspike2 (by Matt Zimmerman) - removes entries in a DS that exceed a specified value. rrdcut (by yours truly) - removes all entries in the RRD file between a specified date and time. I've used both of these scripts for Cricket RRD files, I'm not familiar with the construction of a Smokeping RRD, but these scripts have no Cricket-specific stuff in them so they might work for you. Suggest you set up a test copy of an RRD and experiment with it. -- Ed -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/smokeping-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
