empty/broken extra graphs place holders 4.3.17
I found a similar posting that better describes my problem <http://lists.xymon.com/archive/2012-March/034151.html>;. Apparently it's a well known issue with trends and mulitgraph. I removed the TRENDS:*,disk:disk|iostat-disk|iostat-part from the hosts.cfg entry and changed the GRAPHS= stanza in the xymonserver.cfg and added iostat-disk,iostat-part after "disk" GRAPHS="la,disk,iostat-disk,iostat-part and now the broken iostat-disk and iostat-part graphs are gone, but the some of the normal disk graphs still display broken/empty graphs due to design of the mulitgraphs, i believe. /* * Some reports (disk) use the number of lines as a rough measure for how many * graphs to build. * What we *really* should do was to scan the RRD directory and count how many * RRD database files are present matching this service - but that is way too * much overhead for something that might be called on every status logged. */ Thanks On Sun, Dec 7, 2014 at 8:41 PM, Scott Pfister <user-3f57de7c453d@xymon.invalid> wrote:
Upgraded from 4.2.3 to 4.3.17 and have noticed some strange behavior that is causing empty (broken) or extra graphs in 4.3.17 for the linux-iostat graphs as described in http://www.docum.org/drupal/content/linux-iotstat-graphs The linux-iostats script has been in use for years with out issue, until the upgrade. Now that we have upgraded to 4.3.17. There is only one iostat-disk.*.rrd file. How is first=5&count=4 calculated? it's redundant and empty. The first=1&count=4 is good. See debug snipit below. is tthe tps:Guage is being counted as extra graph value? I've looked at this until my eyes have crossed. Hoping a fresh set of eyes can point me in the right direct.ion.
