zanalyse

Using zanalyse:

zanalyse [-i intervall] [-n numberLongRequests] [[-b] requestsBasename] [[-d] startDate]

prints an 'sar' like requests summary from the Zope requests log file identified by requestsBasename and startDate.

The '-i' option specifies the granularity in minutes. It defaults to "10".

requestsBasename is either an instance tag (in which case it expands to '/var/log/zope/requestsBasename/zope_requests.') or the name of a zope requests file (not ending in '.') or of a zope requests file family (ending in '.'). requestsBasename defaults to the instance tag 'Main'. startDate must have the format year, month and day, each with 2 digits e.g. '040803'. It defaults to the current date. Note that requestsBasename must be an instance tag or a family name, when you default startDate.

Example output:

$ bin/zanalyse -i 10 instance

short    load    reqs    rate     avg     min     max  median
         0.05     217    0.36     145       3   24640       5

ztop

Using ztop:

ztop [-i interval] [-s shortPeriod] [-m medPeriod] [-l longPeriod]
     [-n numberLongRequests [-t time] [-r]] [[-b] requestsBasename] [[-d] startDate]

displays request information by analysis of the Zope requests log file identified by requestsBasename and startDate.

Information contains summaries for up to three periods: 'short', 'med' and 'long'. Their length is given by shortPeriod (default: 120), medPeriod (default: 600) and longPeriod (default: 3600) in seconds. Summaries contain load averaged over the period, number of finished requests, request rate, average, min, max and median request times (in ms) and the numberLongRequests (default: 3) longest requests in this period. A period length of "0" suppresses information about this period.

The information is repeated every interval seconds. interval defaults to the value of shortPeriod or 120. A "0" value causes 'ztop' to stop after one display.

The '-t' option tells 'ztop' to display information for time and then to stop. time is an ISO datetime or time value, e.g. '2004-08-03T12:00:00' or '12:00:00'.

The '-r' option tells 'ztop' to display information for the last restart time and then to stop. '-r' is equivalent to '-t <restartTime>'. This is meant to facilitate the analysis of restarts.

requestsBasename is either an instance tag (in which case it expands to '/var/log/zope/requestsBasename/zope_requests.') or the name of a zope requests file (not ending in '.') or of a zope requests file family (ending in '.'). requestsBasename defaults to the instance tag 'Main'. startDate must have the format year, month and day, each with 2 digits e.g. '040803'. It defaults to the current date. Note that requestsBasename must be an instance tag or a family name, when you default startDate.
