It shouldn't segfault. That's not right. Is 1.0.46 the latest version? Checking... no, it isn't, 1.0.50 is. Maybe this is a known bug fixed in newer versions. Anyway, unless I'm mistaking, it should produce an error message about a non-existing file. This one to be precise: "tgcp_to_ncsa_home,package=tgcp,service=transfer,serviceType=data,resource=ia64,site=anl,vo=teragrid.rrd" Yes, that's one big filename. Or maybe it selects "tgcp,service=transfer,serviceType=data,resource=ia64,site=anl,vo=teragrid.rrd" or maybe "transfer,serviceType=data,resource=ia64,site=anl,vo=teragrid.rrd" and so on. Also, I'm not sure about the DEFinded datasource name "exitStatus,test" or perhaps "exitStatus,test=tgcp_to_ncsa_home,package" or perhaps "exitStatus,test=tgcp_to_ncsa_home,package=tgcp,service" and so on. Where did you get the idea to use commas and multiple equal signs? What is your intention? > DEF:ncsa_home=exitStatus,test=tgcp_to_ncsa_home,package=tgcp,service=transfe > r,serviceType=data,resource=ia64,site=anl,vo=teragrid.rrd:tgcp:LAST \ If you want datasource "tgcp" from file "teragrid.rrd", the line should read DEF:ncsa_home=teragrid.rrd:tgcp:LAST or DEF:ncsa_home=/path/to/teragrid.rrd:tgcp:LAST Simple: name to use, followed by "=", followed by a filename, followed by a colon, followed by the datasource name you want from that file, etc. If you want multiple datasources, you need to use multiple DEF statements. DEF:var1=/path/to/teragrid.rrd:ds1:LAST DEF:var2=/path/to/teragrid.rrd:ds2:LAST DEF:var3=/path/to/other.rrd:ds1:LAST DEF:var4=/path/to/other.rrd:ds2:LAST and so on.
