<div dir="ltr">Hi,<div><br></div><div>I've built the beginnings of a simple tool that lets you specify rrd aggregation 'recipes' using regular expressions on the paths to rrd files [1]. So suppose you have data for N nodes in the following directory structure, where the first two letters refer to a location:</div>
<div><br></div><div><a href="http://us1.mydomain.org">us1.mydomain.org</a></div><div><a href="http://us2.mydomain.org">us2.mydomain.org</a></div><div>...</div><div><a href="http://eu1.mydomain.org">eu1.mydomain.org</a></div>
<div><a href="http://eu2.mydomain.org">eu2.mydomain.org</a></div><div>...</div><div><br></div><div>Then you could aggregate the data for all possible locations using this regular expression:</div><div>(..)\d+.<a href="http://mydomain.org/.*rrd">mydomain.org/.*rrd</a></div>
<div><br></div><div>Rather than building a new processor, I leveraged rrdxport's nice aggregation interface. In other words, recipes in yaml format are converted into invocations of rrdxport.</div><div><br></div><div>
<b>This works fine, except when the number of DEFS in rrdxport exceeds a certain number. At that point, rrdxport simply returns without giving any error messages.</b></div><div><br></div><div>Is there a limit on the number of DEFS you can pass in a single rrdxport invocation, and if so then is there a way of raising the limit?</div>
<div><br></div><div>This is the version of rrdtool that I am using:</div><div><br></div><div><div>RRDtool 1.4.8 Copyright 1997-2013 by Tobias Oetiker <<a href="mailto:tobi@oetiker.ch">tobi@oetiker.ch</a>></div><div>
