Chapter 1. Admin Guide

1.1. Overview

   The event_flatstore module provides a logging facility for
   different events, triggered through the OpenSIPS Event
   Interface, directly from the OpenSIPS script. The module logs
   the events along with their parameters in plain text files.

1.2. Flatstore socket syntax

   flatstore:path_to_file

   Meanings:
     * flatstore: - informs the Event Interface that the events
       sent to this subscriber should be handled by the
       event_flatstore module.
     * path_to_file - path to the file where the logged events
       will be appended to. The file will be created if it does
       not exist. It must be a valid path and not a directory.

1.3. Dependencies

1.3.1. OpenSIPS Modules

   The following modules must be loaded before this module:
     * No dependencies on other OpenSIPS modules.

1.4. External Libraries or Applications

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

1.5. Exported Parameters

1.5.1. max_open_sockets (integer)

   Defines the maximum number of simultaneously opened files by
   the module. If the maximum limit is reached, an error message
   will be thrown, and further subscriptions will only be possible
   after at least one of the current subscriptions will expire.

   Default value is “100”.

   Example 1.1. Set max_open_sockets parameter
...
modparam("event_flatstore", "max_open_sockets", 200)
...

1.5.2. delimiter (string)

   Sets the separator between the parameters of the event in the
   logging file.

   Default value is “,”.

   Example 1.2. Set delimiter parameter
...
modparam("event_flatstore", "delimiter", ";")
...

1.5.3. file_permissions (string)

   Sets the permissions for the newly created logs. It expects a
   string representation of a octal value.

   Default value is “644”.

   Example 1.3. Set file_permissions parameter
...
modparam("event_flatstore", "file_permissions", "664")
...

1.5.4. suppress_event_name (int)

   Suppresses the name of the event in the log file.

   Default value is “0/OFF” (the event's name is printed).

   Example 1.4. Set suppress_event_name parameter
...
modparam("event_flatstore", "suppress_event_name", 1)
...

1.6. Exported Functions

   No exported functions to be used in the configuration file.

1.7. Exported MI Functions

1.7.1.  evi_flat_rotate

   It makes the processes reopen the file specified as a parameter
   to the command in order to be compatible with a logrotate
   command. If the function is not called after the mv command is
   executed, the module will continue to write in the renamed
   file.

   Name: evi_flat_rotate

   Parameters: path_to_file

   MI FIFO Command Format:
                opensips-cli -x mi evi_flat_rotate _path_to_log_file_

   (project_lines_added / project_commits) + author_lines_deleted
   / (project_lines_deleted / project_commits)

   (2) including any documentation-related commits, excluding
   merge commits. Regarding imported patches/code, we do our best
   to count the work on behalf of the proper owner, as per the
   "fix_authors" and "mod_renames" arrays in
   opensips/doc/build-contrib.sh. If you identify any
   patches/commits which do not get properly attributed to you,
   please submit a pull request which extends "fix_authors" and/or
   "mod_renames".

   (3) ignoring whitespace edits, renamed files and auto-generated
   files
