I'll give this a try today before I rectify the DNS issue altogether. I wanted to track down and understand the cause internally before just fixing DNS... This actually seems to describe the situation I have now though, only the hosts with incorrect PTR's and not populating their RRD's; also the cluster stats aren't being aggregated.
Thanks for your input! /eli -----Original Message----- From: Martin Knoblauch [mailto:[EMAIL PROTECTED] Sent: Thu 3/30/2006 1:36 AM To: Eli Stair; [EMAIL PROTECTED] Cc: [email protected] Subject: RE: [Ganglia-general] Re: gmetad not updating RRD's/hosts that are proper in gmond XML Eli, OK, the messages coming from RRDTOOL, just telling that you tried to update the same metric with exactely the same timestamp. Do you see any messages prefixed "RRD_create" in your logfiles? The problem is that if one of the rrd_updates fails, gmetad stops working on anything. Do you have a chance to rebuild gmetad with the following patch? It is against current CVS, but should apply against 3.0.2. If it helps, all hosts (metrics) except the one causing problems should be OK. It might not be the real solution, but may help us to track it down. [gmetad]$ diff -udp rrd_helpers.c rrd_helpers.c-new --- rrd_helpers.c 2005-03-15 19:11:33.000000000 +0100 +++ rrd_helpers.c-new 2006-03-30 11:28:26.000000000 +0200 @@ -54,7 +54,7 @@ RRD_update( char *rrd, const char *sum, { err_msg("RRD_update (%s): %s", rrd, rrd_get_error()); pthread_mutex_unlock( &rrd_mutex ); - return 1; + return 0; } /* debug_msg("Updated rrd %s with value %s", rrd, val); */ pthread_mutex_unlock( &rrd_mutex ); In addition, do you see any messages prefixed "RRD_create" in your logfiles? You should, as some of the RRD files seem to be missing.
