We have been debugging a problem in 3.1.7 when using gmetric with SPOOF_HOST on large clusters. The symptom is that the individual host data is correct for all hosts and the summary_info data is correct for clusters with <32 hosts, but the summary_info rrd file is missing on clusters with >32 hosts. Latests TOT code fixes this problem. It may be related to this fix in process_xml.c: > /* $Id: process_xml.c 2277 2010-02-05 22:03:45Z bnicholes $ */ 6a7 > #include <ganglia.h> 810a812,818 > /* do not add every SPOOF_HOST element to the summary table. > if the same metric is SPOOF'd on more than ~MAX_EXTRA_ELEMENTS hosts > then its summary table is destroyed. > */ > if ( strlen(new_name) == 10 && !strcasecmp(new_name, SPOOF_HOST) ) > return 0; Anyway, we are now using the TOT version in production. So far without problems. The improved calendar support is nice also. This change to support clusters with >32 hosts is helpful to us, hopefully it will be retained in the next release. If we have problems with the TOT snapshot, would it be possible for us to patch this one change into a known good release? Suggestions on best path forward? Thanks, Ron
