>In the webfrontend, the summary "CPUs Total" shows nothing, however, the "CPUs Total" for the data_source running gmetad 3.0.7 is correct. I actually had done the 3.0 backport and attached it to bug #76. Then I later saw this behavior as well and had to revert to my original patch. Basically, the /?filter=summary that the web frontend uses no longer works. I can't understand why. While looking at this, I think I see an area for efficiency improvement. Say I have a gmetad "child" that pulls from several large clusters. It must sum up all the hosts of all those clusters to generate its __SummaryInfo__, both for each cluster and for the "child" grid itself. Now I configure a gmetad "parent" which has "child" as one of its sources. It only needs the final sum which child has already calculated. However, it gets the full XML details of "child" and all its individual clusters and even hosts. It looks like it recalculates the sum that child has already calculated. Do I understand this right? For large clusters/grids, this can be a huge amount of XML that is getting passed, parsed and recalculated. I see that in 3.1 the raw XMl gets even larger. What would be cool is if the gmetad could talk to the interactive port of the child gmetad and use the /?filter=summary. Could this work? I tried connecting a data source to the interactive port but I get: poll() timeout for [child] data source after 0 bytes read likely because it is not giving the /?filter=summary command. -twitham ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
