Hi All,

I have setup the web serving benchmark as defined in the installation
guideline. I need to gather
metrics when the frontend saturates. However, I am unable to do that. Once
it reaches around 200-250 users, it starts to throw exceptions such as:


   - Image at http://frontend:80/fileService.php?cache=false&file=e3774t.jpg
   size of 383 bytes is too small. Image may not exist
   - UIDriverAgent[0].146.doAddEvent: Multipart Post did not work, returned
   status code: 504
   - UIDriverAgent[0].125.doLogin: Found login prompt at index 1969, Login
   as d2zg1z6jm, 5876 failed.

I looked at the nginx logs and it has connection timeouts:

[error] 1186#0: *3208 upstream prematurely closed connection while reading
response header from upstream, client: X.X.X.X, server: localhost, request:
"POST /taggedEvents.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000",
host: "frontend"

I tried increasing timeout and keepalive parameters, but it did not help.

I am using variable load distribution, but even with static, the results
are similar. The maximum CPU utilization reached was 95%.

Any suggestion about what can be done is appreciated. Thanks!

Regards,
Shashank
