Handler that uses hotshot to store profile data.
|
||
|
|
|
||
|
|
Stores profile data in PROFILE_DATA_DIR. Since hotshot has no way (that I
|
||
|
|
know of) to append profile data to a single file, each request gets its own
|
||
|
|
profile. The file names are in the format <url>.<n>.prof where <url> is
|
||
|
|
the request path with "/" replaced by ".", and <n> is a timestamp with
|
||
|
|
microseconds to prevent overwriting files.
|
||
|
|
|
||
|
|
Use the gather_profile_stats.py script to gather these individual request
|
||
|
|
profiles into aggregated profiles by request path.
