1. Overview

   This module provides a statistics collector engine. It can track the
   values of various internal Kamailio statistics for a specific period of
   time, allowing to retrieve them or a report over them via RPC commands.

2. Dependencies

   2.1. Kamailio Modules
   2.2. External Libraries or Applications

2.1. Kamailio Modules

   The following modules must be loaded along this module:
     * various - for getting access to the statistics exported by these
       modules.

2.2. External Libraries or Applications

   The following libraries or applications must be installed before
   running Kamailio with this module loaded:
     * none

3. Parameters

   3.1. interval (int)
   3.2. items (int)
   3.3. track (str)

3.1. interval (int)

   Timer interval when to record the value for statistics.

   Default value is 900 (15min).

   Example 1.1. Set interval parameter
...
modparam("statsc", "interval", 300)
...

3.2. items (int)

   How many items to store for each statistic.

   Default value is 100.

   Example 1.2. Set items parameter
...
modparam("statsc", "items", 200)
...

3.3. track (str)

   Specify the statistics to track. The parameter can be set many times
   and one value can speficy many statistics.

   The format is "rname=sname", where the rname is the name for report and
   sname is internal Kamailio statistic name.

   Next statistics are tracked by default:
     * shm.free - the internal statistc 'free_size' (from group 'shmem').
     * shm.used - the internal statistc 'used_size' (from group 'shmem').
     * shm.real_used - the internal statistc 'real_used_size' (from group
       'shmem').

   Default value is "".

   Example 1.3. Set track parameter
...
modparam("statsc", "track", "req.received=rcv_requests")
modparam("statsc", "track", "req.received=rcv_requests;rpl.received=rcv_replies"
)
...

4. RPC Commands

   4.1. statsc.exec

4.1.  statsc.exec

   Get the report of recorded statistics.

   Name: statsc.report

   Parameters:
     * _type_ :
          + “list”: list recorded values
          + “diff”: show diff between recorded values
     * _name_: (optional) name of the statistic to show the report for. If
       missing or set to 'all', then the reports for all recorded
       statistics are done.
     * _limit_: (optional) how many items to be included in the report

   Example:
...
# prototype: kamcmd statsc.report _type_ _name_ _limit_
kamcmd statsc.report list
kamcmd statsc.report list all 10
kamcmd statsc.report diff
...
