"""Tools for analyzing ZEO Server logs.
This script contains a number of commands, implemented by command
functions. To run a command, give the command name and it's arguments
as arguments to this script.
Commands:
blocked_times file threshold
Output a summary of episodes where thransactions were blocked
when the episode lasted at least threshold seconds.
The file may be a file name or - to read from standard input.
The file may also be a command:
script blocked_times 'bunzip2 <foo.log.bz2' 60
If the file is a command, it must contain at least a single
space.
The columns of output are:
- The time the episode started
- The seconds from the start of the episode until the blocking
transaction finished.
- The client id (host and port) of the blocking transaction.
- The seconds from the start of the episode until the end of the
episode.
time_calls file threshold
Time how long calls took. Note that this is normally combined
with grep to time just a particulat kind of call:
script time_calls 'bunzip2 <foo.log.bz2 | grep tpc_finish' 10
time_trans threshold
The columns of output are:
- The time of the call invocation
- The seconds from the call to the return
- The client that made the call.
time_trans file threshold
Output a summary of transactions that held the global transaction
lock for at least threshold seconds. (This is the time from when
voting starts until the transaction is completed by the server.)
The columns of output are:
- time that the vote started.
- client id
- number of objects written / number of objects updated
- seconds from tpc_begin to vote start
- seconds spent voting
- vote status: n=normal, d=delayed, e=error
- seconds wating between vote return and finish call
- time spent finishing or 'abort' if the transaction aborted
minute file
Compute production statistics by minute
The columns of output are:
- date/time
- Number of active clients
- number of reads
- number of stores
- number of commits (finish)
- number of aborts
- number of transactions (commits + aborts)
Summary statistics are printed at the end
minutes file
Show just the summary statistics for production by minute.
hour file
Compute production statistics by hour
hours file
Show just the summary statistics for production by hour.
day file
Compute production statistics by day
days file
Show just the summary statistics for production by day.
verify file
Compute verification statistics
The columns of output are:
- client id
- verification start time
- number of object's verified
- wall time to verify
- average miliseconds to verify per object.
