MODULE SUMMARY

Instrumentation Functions for STANDARD-MIB and SNMPv2-MIB

DESCRIPTION

This module implements the instrumentation functions for the STANDARD-MIB and SNMPv2-MIB, and functions for configuring the database.

The configuration files are described in the SNMP User's Manual.

EXPORTS

configure(ConfDir) -> void()

Types:
ConfDir = string()

This function is called from the supervisor at system start-up.

Inserts all data in the configuration files into the database. It does not destroy any old permanent data. For example, if a manager has changed the value for sysContact, this value will be preserved even if the agent reboots.

All snmp counters are set to zero.

If an error is found in the configuration file, it is reported using the function snmp_error:config_err/2, and the function fails with reason configuration_error.

ConfDir is a string including a trailing directory delimiter, which points to the directory where the configuration files are found.

inc(Name) -> void()
inc(Name, N) -> void()

Types:
Name = atom()
N = integer()

Increments a variable in the MIB with N, or one if N is not specified.

reconfigure(ConfDir) -> void()

Types:
ConfDir = string()

This function works as configure/1, but it forces a reload of the configuration files; i.e. changes done by the manager are lost.

sys_up_time() -> Time

Types:
Time = int()

Gets the system up time in hundredth of a second.
