Hi, I have both an architecture with: Apache+Fpm and Nginx+Fpm. I must test
them with an access log replay strategy.

Here is the format of the log:

00:00:00 vhost1.com /static_file_of_5279_bytes.png
00:00:00 vhost6.com /script.php?output=17359
00:00:01 vhost7.com /static_file_of_595_bytes.png
00:00:01 vhost8.com /static_file_of_1899_bytes.png
00:00:01 vhost2.com /script.php?output=2486274

Does anybody of you know HTTP/WebServer benchmark tools which can set their
proper header by reading the log, and generate the traffic whose rate is
based on the timestamp of the log? thanks.

it's going to take some work, but have a look at jmeter:

and/or grinder (we use this for very custom benchmarks, i imagine you could
program access log replays as well, its basically anything you can write in
python:

Thanks, does Grinder provide support to plot something like response-rate
stats-graph?

tried to make a grinder script which reads the file and sleep when seconds
change in order to replicate the traffic rate. It nearly works ok for a low
traffic log. But it introduces several shifts when it parses high-traffic
rate log: seems like that HTTPRequest.GET() behaves only in synchronous
way, and basically it stops the script until he receives a response from
the server.

Here is the code:

-----------------------

test1 = Test(1, "Log Replay Test")
request1 = HTTPRequest()
test1.record(request1)
LOG_FILE="/home/renzo/Desktop/test/grinder-3.11/logreplay/fasce/bot-0405.log"
def getSeconds(text):
items=text.strip().split(' ')
times=items[0]
values=times.strip().split(':')
seconds=values[2]
return int(seconds)

def calculateSleepTime(before,actual):
result=actual-before
if result < 0:
result=result+60
else:
result=result
return result


class TestRunner:
def __call__(self):
stream=open(LOG_FILE,"r")
line=stream.readline()
beforeTimeStamp=getSeconds(line)

while line:
actualTimeStamp=getSeconds(line)
items=line.strip().split(' ')
url="http://"+items[1]+""+items[2]+""
var=calculateSleepTime(beforeTimeStamp,actualTimeStamp)
grinder.sleep(var*1000)
request1.GET(url)
print line
beforeTimeStamp=actualTimeStamp
line=stream.readline()

--------------------------------------------

Is there a way to use request.GET() but without stopping the worker? Thanks.
