ziorep_traffic - Traffic report

Edit online

Use the ziorep_traffic command produces a report about the systems I/O traffic through FCP channels and traffic latency. Use the .log file from ziomon as input.

There are two reports available, varying by the level of detail:
  • The default report shows traffic information on a summary level.
  • A report that is limited to certain devices that gives detailed traffic information.
Each device is identified by WWPN or LUN and gives information about I/O rate and throughput and latencies in the I/O subsystem, channel, and fabric. See the ziorep_traffic man page for the complete syntax and all options.

ziorep_traffic syntax

See the ziorep_config man page for the complete syntax and all options.

1  ziorep_traffic?  -i <time> ?  -D?  -C <val>  <out_file>

Example

To generate a traffic report from the trace_data.log created by ziomon, for all devices with the data aggregated to a 60-second interval, issue the following command:
[root@system]# ziorep_traffic -i 60  trace_data.log
To generate the same traffic report and export it to a CSV file, issue the following command:
[root@system]# ziorep_traffic -i 60  trace_data.log -x
In this example, the data is exported to a file called trace_data_traffic.csv.
