    <p>I'm trying to benchmark a simple webserver I wrote, but I'm having trouble deciphering what Autobench has outputted. I've been googling all over for help on this (even going through the autobench and httperf source code) but haven't been able to grok what's going on.</p> <p>I ran the following benchmark on my server:</p> <pre><code>autobench --single_host --host1 10.0.1.5 --port1 5555 --uri1 /Tests --quiet --low_rate 20 --high_rate 200 --rate_step 20 --num_call 10 --num_conn 5000 --timeout 5 --file results.csv </code></pre> <p>Here's my results.csv file (with some extra whitespace for readability):</p> <pre><code>dem_req_rate,req_rate,con_rate,min_rep_rate,avg_rep_rate,max_rep_rate,stddev_rep_rate,resp_time,net_io,errors 200, 40.0, 20.0, 20.0, 20.0, 20.0, 0.0, 6.2, 15.6, 100 400, 80.0, 40.0, 40.0, 40.0, 40.0, 0.0, 6.4, 31.2, 100 600, 119.9, 60.0, 57.0, 59.9, 61.4, 0.9, 17.9, 46.8, 100.160256410256 800, 159.5, 79.9, 76.0, 79.5, 82.4, 2.1, 32.5, 62.1, 100.48231511254 1000, 155.9, 94.0, 55.8, 64.7, 75.8, 6.2, 129.4, 50.4, 151.975683890577 1200, 156.7, 112.6, 28.0, 45.5, 63.2, 11.3, 148.0, 38.9, 255.232261357836 1400, 154.7, 121.8, 22.2, 38.1, 51.6, 9.3, 175.6, 34.2, 328.299409061064 1600, 154.5, 134.7, 15.6, 28.7, 52.8, 13.3, 211.6, 27.7, 498.504486540379 1800, 143.5, 138.7, 3.2, 18.6, 41.0, 11.7, 185.1, 21.1, 768.049155145929 2000, 158.8, 159.4, 5.6, 18.0, 45.6, 14.6, 234.7, 21.6, 925.925925925926 </code></pre> <p>I'm wondering:</p> <p>What does <code>dem_req_rate</code> mean? What does <code>net_io</code> mean? What does <code>errors</code> mean? How does <code>errors</code> relate to <code>dem_req_rate</code>? What units are all of these in?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
