STATISTICS module
Admin Guide
Section titled “Admin Guide”Overview
Section titled “Overview”The Statistics module is a wrapper over the internal statistics manager, allowing the script writer to dynamically define and use of statistic variables.
By bringing the statistics support into the script, it takes advantage of the script flexibility in defining logics, making possible implementation of any kind of statistic scenario.
Statistic Groups
Section titled “Statistic Groups”Starting with OpenSIPS 2.3, statistics may be grouped by prefixing their names with the name of the desired group, along with a colon separator (e.g. $stat(method:invite) or update_stat(“packets:$var(ptype)”, “+1”)). In order for this to work, the groups must be defined prior to OpenSIPS startup using the modparam stat groups module parameter.
The module allows easy iteration over the statistics of a group using the modfunc stat iter init and modfunc stat iter next functions.
By default, all statistics belong to the “dynamic” group.
Dependencies
Section titled “Dependencies”OpenSIPS Modules
Section titled “OpenSIPS Modules”The following modules must be loaded before this module:
- No dependencies on other OpenSIPS modules.
External Libraries or Applications
Section titled “External Libraries or Applications”The following libraries or applications must be installed before running OpenSIPS with this module loaded:
- None.
Exported Parameters
Section titled “Exported Parameters”variable (string)
Section titled “variable (string)”Name of a new statistic variable. The name may be followed by additional flag which describe the variable behavior:
- no_reset : variable cannot be reset.
modparam("statistics", "variable", "register_counter")modparam("statistics", "variable", "active_calls/no_reset")stat_groups (string)
Section titled “stat_groups (string)”A comma-separated values string, specifying the statistic groups that may be used throughout the OpenSIPS script. Groups cannot contain leading or trailing whitespace characters.
modparam("statistics", "stat_groups", "method, packet, response")Exported Functions
Section titled “Exported Functions”update_stat(variable, value)
Section titled “update_stat(variable, value)”Updates the value of the statistic variable with the new value.
Meaning of the parameters is as follows:
- variable - variable to be updated (it can be a string or a pseudovariable);
- value - value to update with; it may be also negative; variables (holding integer values) are also allowed.
This function can be used from REQUEST_ROUTE, BRANCH_ROUTE, FAILURE_ROUTE and ONREPLY_ROUTE.
...update_stat("register_counter", "+1");...$var(a_calls) = "active_calls";update_stat("$var(a_calls)", "-1");...reset_stat(variable)
Section titled “reset_stat(variable)”Resets to zero the value of the statistic variable.
Meaning of the parameters is as follows:
- variable - variable to be reset-ed (it can be a string or a pseudovariable).
This function can be used from REQUEST_ROUTE, BRANCH_ROUTE, FAILURE_ROUTE and ONREPLY_ROUTE.
...reset_stat("register_counter");...$var(reg_counter) = "register_counter";update_stat("$var(reg_counter)");...stat_iter_init(group, iter)
Section titled “stat_iter_init(group, iter)”Re-initializes “iter” in order to begin iterating through all statistics belonging to the given “group”.
Meaning of the parameters is as follows:
- group - string
- iter - string (internally matched to a corresponding iterator)
This function can be used from REQUEST_ROUTE, BRANCH_ROUTE, FAILURE_ROUTE and ONREPLY_ROUTE.
...stat_iter_init("packet", "iter");...stat_iter_next(name, val, iter)
Section titled “stat_iter_next(name, val, iter)”Attempts to fetch the current statistic to which “iter” points. If successful, the relevant data will be written to “name” and “val”, while also advancing “iter”. Returns negative when reaching the end of iteration.
Meaning of the parameters is as follows:
- name - script variable
- val - script variable
- iter - string (internally matched to a corresponding iterator)
This function can be used from REQUEST_ROUTE, BRANCH_ROUTE, FAILURE_ROUTE and ONREPLY_ROUTE.
...stat_iter_init("packet", "iter");while (stat_iter_next("$var(k)", "$var(v)", "iter")) { ...}...Exported Pseudo-Variables
Section titled “Exported Pseudo-Variables”Allows “get” or “reset” operations on the given statistics.
The name of a statistic may be optionally prefixed with a searching group, along with a colon separator.
If a searching group is not provided, the statistic is first searched for in the core groups. If not found, search continues with the “dynamic” group which, by default, holds all non-explicitly grouped statistics which are not exported by the OpenSIPS core.
...xlog("SHM used size = $stat(used_size), no_invites = $stat(method:invite)\n");...$stat(err_requests) = 0;...doc copyrights:
