Both llstat and llobdstat are great tools for summarizing Lustre /proc data for analysis and plotting, but am not aware of a similar Lustre tool for rpc_stats or brw_stats. Have found that Collectl parses these files much like ll[obd]stat parses stats files, but there appears to be an incompatibility (http://sourceforge.net/p/collectl/bugs/21/) which prevents Collectl from fully parsing rpc_stats.
Thus, having a Lustre provided/supported tool to parse these files would seem to be of great benefit to monitoring [brw|rpc]_stats files over time. Thanks.
