* buildstats.bbclass: Adding disk io measurementBeth Flanagan2011-08-051-78/+142
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds disk-io statistics functionality on a build and per-task basis. It pulls measurements for whatever partition TMPDIR exists on. This data could be off if SSTATE_DIR and DL_DIR exist on a different partition/volume. Notes on what this pulls: ReadsComp: Total number of reads complete ReadsMerged: Total number of adjacent reads merged SectRead: Total number of sectors read TimeReads: Total number of m/s spent reading WritesComp: Total number of writes completed SectWrite: Total number of sectors written TimeWrite: Total number of m/s spent writing IOinProgress: Total amount of IO in progress at the time of we look at /proc/diskstats. TimeIO: Total number of m/s spent doing IO WTimeIO: Weighted time doing I/O. From iostats.txt: "This field is incremented at each I/O start, I/O completion, I/O merge, or read of these stats by the number of I/Os in progress (field 9) times the number of milliseconds spent doing I/O since the last update of this field. This can provide an easy measure of both I/O completion time and the backlog that may be accumulating."
