ziomon - Collect FCP performance data

Use the ziomon tool to gather FCP performance data. The monitor tool ziomon collects information and details about:

Use the ziorep tools to analyze the reports created by ziomon. The process is illustrated in Figure 1.

Authorization

Root access is required on Linux™ operating systems.

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

-i <interval>: Specifies the elapsed time between writing data to disk in seconds. Defaults to 60 seconds.
-d <duration>: Specifies the monitoring duration in minutes. Must be a multiple of the interval length.
-l <size limit of output file>: Defines the upper limit of the output files. Must include one of the suffixes M (megabytes), G (gigabytes), or T (terabytes). This limit is only a tentative value that can be slightly exceeded.
-o <output file>: Specifies the prefix for the log file, configuration file, and aggregation file.
<device>: Denotes one or more device names that are separated by blanks.

To generate a diagnostic report for devices /dev/sda and /dev/sdb, issue the command:

[root@system]# ziomon -i 20 -d 5 -l 50M -o trace_data /dev/sda /dev/sdb

The ziomon tool creates two output files in the directory where it was started:

<output file>.cfg holds various configuration data from the system
<output file>.log holds the raw data samples that are taken during the data collection phase in a binary format
<output file>.agg aggregates old sample data when the .log file grows larger than the allowed limit, thus freeing the log file for more recent data.
