如何诊断长期运行的PHP curl请求

Question

Our PHP web app makes a series of curl requests to APIs in response to certain requests. We're debugging a problem where the request occasionally times out after 30 seconds with a 503 response code... we're pretty sure it's because one (or two) of the curl requests is taking too long.

In an effort to diagnose which curl requests are the problem, we'd like to log or track the individual requests. We're hosting the app on a Heroku Cedar instance with the Logentries add-on and we also use New Relic, but neither tools seem to offer an option to log/track the individual curl s. How do we do this?

I know we could set variables with timestamps and log them manually... but suspect we'd be "reinventing the wheel." What's the best way to do this, preferably without messing with our code base.

Answer 1

You're going to need xdebug and code modifications to diagnose it. I guess you don't have to change much on the code but set

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT ,0);  //set it to 0 for infinity
curl_setopt($ch, CURLOPT_TIMEOUT, 400); //timeout in seconds, increase that 

also don't forget to enlarge time execution of php script self:

`set_time_limit(0);//` to infinity for example
