NAME
       schedulerinfo - Displays extended scheduler tasks information.

SYNOPSIS
       torrus schedulerinfo --tree=TREENAME [options...]

DESCRIPTION
       This utility displays the extended scheduler tasks information for tree
       TREENAME on standard output. This might be useful for scheduler
       planning and analysis.

OPTIONS
       --config
           Reports scheduler's configuration. The values are explained below.

           Total collector/monitor leaves: N
                   Total number of datasources being processed by collector or
                   monitor daemon.

           Scheduled leaves by type
                   Torrus supports arbitrary number of collector types, and
                   this report shows how many datasources belong to every
                   type. Currently the monitor leaves are not divided into
                   types.

           Least common period: N seconds
                   The report below shows how the tasks are distributed across
                   the time line, and the least common period shows the period
                   of this time line.

           Tasks execution timeline
                   This report tells which task and how many datasources are
                   involved in each task startup event, and how these events
                   are dispersed across the time.  The column Interval shows
                   the time interval from each task execution event to the
                   next event on the timeline.

       --runtime
           Reports scheduler's runtime statistics, such as running cycle
           times, late starts etc. The meaning of the output values is as
           follows. Values that have zero values are usually not printed.

           Task: Name, Period: N seconds, Offset: M seconds
                   Each scheduler task is characterized by its name (usually
                   Collector or Monitor), period, and timeoffset. Fore
                   example, if period is set to 300 seconds, and offset is 14
                   seconds, then the task would be executed at 00:00:14,
                   00:05:14, 00:10:14, and so on for every hour in a day.

           N running cycles passed
                   How many times the task was executed since last reset. The
                   counter is normally reset after torrus_compilexml(1)
                   successfully compiles the configuration.

           N late starts
                   How many times the task has started with a delay from its
                   normal schedule.

           N too long runs
                   How many times the task execution time was longer than its
                   period.

           N overrun periods
                   How many periods have been missed because of too long
                   executions.

           N missed periods
                   How many periods were missed because of any reason (such as
                   other tasks delaying).

           Min, Max, Average, Exp Average
                   The time values are displayed in four columns: Mimimum,
                   Maximum and Average values since last reset, and
                   Exponential decay value, which may be interpreted as the
                   average for last several values. With defaults defined in
                   torrus-config.pl, 95% of the average is calculated from
                   last 3 values.

           Running Time
                   How long the task executes each period.

           Late Start
                   How long the task start was delayed.

           Too Long
                   How much time the too long run took.

           RRD Queue
                   In a multithreaded environment, the RRD files are writen in
                   a background thread. This value shows the length of the RRD
                   update queue at the beginning of each update cycle.

       --help
           Displays a help message.
