Description of problem: I'll attach three different archives, one for incoming traffic, one for outgoing traffic, and one containing both, all generated from the same CSV data. Using pminfo/pmval shows no differences for the corresponding metrics. Opening csv-data-lan-out with "pmchart -t 1m -a csv-data-lan-out" and plotting csv_data_lan_out.test.lan_outbytes_linux.eth0.txbyt_s works as expected but opening csv-data-lan-both with "pmchart -t 1m -a csv-data-lan-both" and plotting csv_data_lan_both.test.lan_outbytes_linux.eth0.txbyt_s produces an empty view. Version-Release number of selected component (if applicable): pcp-3.8.0-1.el6.x86_64 pcp-gui-1.5.8-2.el6.x86_64

| ... plotting csv_data_lan_both.test.lan_outbytes_linux.eth0.txbyt_s | produces an empty view It appears there is only a single value in the archive for this metric - is that expected? It also has a timestamp that is for the final fetch group in the archive. $ pmdumplog -z -a csv-data-lan-both | grep csv_data_lan_both.test.lan_outbytes_linux.eth0.txbyt_s PMID: 245.0.12 (csv_data_lan_both.test.lan_outbytes_linux.eth0.txbyt_s) 23:59:00.000 245.0.12 (csv_data_lan_both.test.lan_outbytes_linux.eth0.txbyt_s): value 657803.87 pmchart is going to have a hard time working with a single data point. Could this be a failure to import all the data you expected, Marko? (and also, is it an archive that would be susceptible to the earlier log import issues around out-of-time-order records?) thanks.
As per earlier comments, on closer inspection of the archive this appears to not be a bug.
Hi Nathan, yes, agreed, all the evidence suggests that this was also collateral damage of bug 958745. Thanks.
