I am facing an issue in running tracerstats and tracestats tools offered by libtrace and it fails with the following exception:
Failed to start trace(equinix-chicago.dirA.20150219-125911.UTC.anon.pcap.gz): Trace cannot start IO in pcapfile_start_input()
I tried the same command with different filters and different data set as well but it does not work. Moreover, I presume that tracestats would return count data in terms of the packet count against each time interval.
