Reports are of two types: cumulative or detailed. The default is cumulative.
Data is taken from the Zope detailed request log (the -M log).
For cumulative reports, each line in the profile indicates information
about a Zope method (URL) collected via the detailed request log (the -M log).
For detailed reports, each line in the profile indicates information about
a single request.
'filename' is the path to the '-M' log that contains detailed request data.
If a 'sort' value is specified, sort the profile info by the spec. The sort
order is descending unless indicated. The default cumulative sort spec is
'total'. The default detailed sort spec is 'start'.
For cumulative reports, the following sort specs are accepted:
'hits' -- the number of hits against the method
'hangs' -- the number of unfinished requests to the method
'max' -- the maximum time in secs taken by a request to this method
'min' -- the minimum time in secs taken by a request to this method
'mean' -- the mean time in secs taken by a request to this method
'median' -- the median time in secs taken by a request to this method
'total' -- the total time in secs across all requests to this method
'url' -- the URL/method name (ascending)
For detailed (non-cumulative) reports, the following sort specs are accepted:
'start' -- the start time of the request to ZServer (ascending)
'win' -- the num of secs ZServer spent waiting for input from client
'wout' -- the secs ZServer spent waiting for output from ZPublisher
'wend' -- the secs ZServer spent sending data to the client
'total' -- the secs taken for the request from begin to end
'endstage' -- the last successfully completed request stage (B, I, A, E)
'osize' -- the size in bytes of output provided by ZPublisher
'httpcode' -- the HTTP response code provided by ZPublisher (ascending)
'active' -- total num of requests pending at the end of this request
'url' -- the URL/method name (ascending)
NOTE: 'active' count may be fooled by Zope restarts, which aren't
reflected in the -M log.
If the 'top' argument is specified, only report on the top 'n' entries in
the profile (as per the sort). The default is to show all data in the profile.
If the 'verbose' argument is specified, do not trim url to fit into 80 cols.
If the 'today' argument is specified, limit results to hits received today.
If the 'start' argument is specified in the form 'DD/MM/YYYY HH:MM:SS' (UTC),
limit results to hits received after this date/time.
If the 'end' argument is specified in the form 'DD/MM/YYYY HH:MM:SS' (UTC),
limit results to hits received before this date/time.
Examples:
%(pname)s debug.log
Show cumulative report statistics for information in the file 'debug.log',
by default sorted by 'total'.
%(pname)s debug.log --detailed
Show detailed report statistics sorted by 'start' (by default).
%(pname)s debug.log --cumulative --sort=mean --today --verbose
Show cumulative report statistics sorted by mean for entries in the log
which happened today, and do not trim the URL in the resulting report.
%(pname)s debug.log --detailed --start='2001/05/10 06:00:00'
--end='2001/05/11 23:00:00'
Show detailed report statistics for entries in 'debug.log' which
begin after 6am UTC on May 10, 2001 and which end before
11pm UTC on May 11, 2001.
%(pname)s debug.log --top=100 --sort=max
Show cumulative report of the the 'top' 100 methods sorted by maximum
elapsed time.""" % {'pname':pname}
