问题
Need to use this httperf as ab is returning SSL errors.
Operating System
Ubuntu 16 (Google Cloud Linux tools 4.15.0-1036-gcp #38~16.04.1-Ubuntu)
curl (curl works fine)
ACCESS_TOKEN=`gcloud auth print-access-token`
export URL=https://ml.googleapis.com/v1/projects/dpe-cloud-mle/models/pretrained_model/versions/gpu:predict
curl -X POST $URL -d @image_b64.json \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $ACCESS_TOKEN"
ab testing tool
ab -n 10 -c 1 -s 300 \
-f ALL \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $ACCESS_TOKEN" \
-H "Accept-Encoding: gzip,deflate" \
-p image_b64.json $URL
Returns errors and in packet capture SSL handshake never completes. My understanding is that apache ab does not handle SSL properly most of the time. Reference: How do I fix "ssl handshake failed" with ApacheBench?

How can I configure httperf to send image_b64.json?
image_b64.json is a ~56K file .
httperf --hog --server ml.googleapis.com \
--uri=/v1/projects/dpe-cloud-mle/models/pretrained_model/versions/gpu:predict \
--ssl \
--method=POST \
--add-header="Content-Type: application/json\n" \
--add-header="Authorization: Bearer $ACCESS_TOKEN\n" \
--timeout=10 --num-conns=10 --rate=1 \
--wsesslog=150,0,httprefpost_data.txt
My understanding is that I need to setup: httprefpost_data.txt
/v1/projects/dpe-cloud-mle/models/pretrained_model/versions/gpu:predict method=POST contents=
and next to contents I assume I need to put the whole content of image_b64.json?
When I do that I get:
httperf --hog --server ml.googleapis.com --uri=/v1/projects/dpe-cloud-mle/models/pretrained_model/versions/gpu:predict --ssl --method=POST --add-header="Content-Type: application/json\n" --add-header="Authorization: Bearer $ACCESS_TOKEN\n" --timeout=10 --num-conns=1 --rate=1 --wsesslog=150,0,httprefpost_data.txt
httperf --hog --timeout=10 --client=0/1 --server=ml.googleapis.com --port=443 --uri=/v1/projects/dpe-cloud-mle/models/pretrained_model/versions/gpu:predict --rate=1 --send-buffer=4096 --recv-buffer=16384 --ssl --add-header='Authorization: Bearer ya29.c.ElxdB5jHc_XhRiuh1kBStykfzIOV9NZBL-Wn1NASWcNmtFj7dzWVc6dlTJdFltP3hYfszayQwe7YFW3tIRhC7v9q7nQDWPTgytrI82-Y4pFCYPRSMveffN4ImYK97Q\n' --method=POST --wsesslog=150,0.000,httprefpost_data.txt
