Instrumentation Functions for STANDARD-MIB and SNMPv2-MIB

The module `snmp_standard_mib` 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.

# Summary

## Functions

configure(ConfDir)

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

inc(Name)

Equivalent to `inc/2`.

inc(Name, N)

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

reconfigure(ConfDir)

Inserts all data in the configuration files into the database and destroys all old data, including the rows with StorageType `nonVolatile`. The rows created from the configuration file will have StorageType `nonVolatile`.

reset()

Resets all `snmp` counters to 0.

sys_up_time()

Gets the system up time in hundredth of a second.

# configure(ConfDir)

View Source

    -spec configure(ConfDir) -> snmp:void() when ConfDir :: string().

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

Inserts all data in the configuration files into the database and destroys all old rows with StorageType `volatile`. The rows created from the configuration file will have StorageType `nonVolatile`.

All `snmp` counters are set to zero.

If an error is found in the configuration file, it is reported using the function `config_err/2` of the error report module, and the function fails with the reason `configuration_error`.

`ConfDir` is a string which points to the directory where the configuration files are found.

The configuration file read is: `standard.conf`.

    -spec inc(Name, N) -> snmp:void() when Name :: atom(), N :: integer().

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

# reconfigure(ConfDir)

    -spec reconfigure(ConfDir) -> snmp:void() when ConfDir :: string().

Inserts all data in the configuration files into the database and destroys all old data, including the rows with StorageType `nonVolatile`. The rows created from the configuration file will have StorageType `nonVolatile`.

Thus, the data in the SNMP-STANDARD-MIB and SNMPv2-MIB, after this function has been called, is from the configuration files.

All `snmp` counters are set to zero.

If an error is found in the configuration file, it is reported using the function `config_err/2` of the error report module, and the function fails with the reason `configuration_error`.

`ConfDir` is a string which points to the directory where the configuration files are found.

The configuration file read is: `standard.conf`.
