136 Here is a list of the columns and their descriptions.
137 Timestamps of the frames printed depict the ending of the respective timeframe.
141 I/O rate of the respective device in megabytes per second, considering individual requests and their total processing time, including channel latency, etc.
143 .IR "min" " and " "max"
144 give the minimum and maximum respectively.
148 Throughput of the respective device in megabytes per second, considering times of activity only.
150 .IR "avg" " and " "stdev"
151 give the average utilization as well as its standard deviation respectively.
155 Statistics on the numbers and kinds of I/O requests seen.
158 is the total number of requests,
161 is the number of read requests,
164 is the number of write requests and
167 is the number of bi-directional requests.
170 .BR "I/O subs. lat. in us"
171 Latency of the I/O subsystem in microseconds. This is the time needed to execute a request, from the I/O stack down to the hardware and back up again.
173 .IR "min" ", " "max" ", " "avg" " and " "stdev"
174 give the minimum, maximum and average latency as well as its standard deviation respectively.
177 .BR "channel lat. in us"
178 Channel latency in microseconds. This is the time needed to execute a request on the FCP adapter.
180 .IR "min" ", " "max" ", " "avg" " and " "stdev"
181 give the minimum, maximum and average latency as well as its standard deviation respectively.
184 .BR "fabric lat. in us"
185 Fabric latency in microseconds. This is the time needed for the requests within the fabric, from the FCP adapter to the target device and back again.
187 .IR "min" ", " "max" ", " "avg" " and " "stdev"
188 give the minimum, maximum and average latency as well as its standard deviation respectively.
194 Print a traffic report for all devices.
195 Only data after 8:57 April 5, 2008 should be considered.
196 Data should be aggregated to 60 second intervals.
198 ziorep_traffic -i 60 -b "2008-04-05 08:57" sample.log
202 Print a detailed traffic report for all devices connected to target port 0x500507630313c562.
203 Data should be aggregated over the whole data range.
