glusterfsiostat, in python which you can find attached with this email. Currently, the modifications done by my patch to io-stats which is under review as of now, dumps private information from the xlator object to the proper file for private info in the meta directory. This includes total bytes read/written along with read/write speed in the previous 10 seconds. The speed at every 1 second is identified by it's respective unix timestamp and hence given out in bytes/second. These values at discrete points of time can be used to generate a graph. </div><div class="yiv1423254471" style=""><br clear="none" class="yiv1423254471" style=""></div><div class="yiv1423254471" style="">The python tool first identifies all gluster mounts in the system, identifies the mount path and parses the meta xlator output in order to generate output similar to the iostat tool. Passing '-j' option gives you extra information in a consumable json format. By default, the
tool pretty prints the basic stats which are human readable. This tool is supposed to be a framework on which other applications can be built upon. I'm putting this out for community feedback so as to improve it further.</div><div class="yiv1423254471" style=""><br clear="none" class="yiv1423254471" style=""></div><div class="yiv1423254471" style=""><span class="yiv1423254471" style=""></span></div><div class="yiv1423254471" style="">Do you think the stats and the way they're generated as of now is something that might be usable by someone?
