I solved the problem I was experiencing WRT building a graph from a home-made Nagios style command plugin. Hopefully posting the fix will help the next person.
I thought I had an issue with a Graph Point on a Graph Definition. The actual issue was up at the Data Sources level. For the Data Source named "status" the command was executing correctly, but the DataPoint "ut" had the wrong Type. This mean the RRD file was not storing the data I expected. This mean the graph would be wrong, as it's built from the RRD file . A setting of Type: GUAGE appears to provide the data I expect. A setting of Type: COUNTER does not work correctly for this data. Neither does Type: ABSOLUTE. The RRD file for device batty from Data Source status and data point ut is stored at /opt/zenoss/perf/Devices/batty/status_ut.rrd on my system. These two commands were really useful in debugging the issue: Code: $ rrdtool info /opt/zenoss/perf/Devices/batty/status_ut.rrd $ rrdtool fetch /opt/zenoss/perf/Devices/batty/status_ut.rrd AVERAGE Thanks, David -------------------- m2f -------------------- Read this topic online here: http://forums.zenoss.com/viewtopic.php?p=28491#28491 -------------------- m2f -------------------- _______________________________________________ zenoss-users mailing list [email protected] http://lists.zenoss.org/mailman/listinfo/zenoss-users
