# snmp_target_mib

### MODULE

snmp_target_mib

### MODULE SUMMARY

Instrumentation Functions for SNMP-TARGET-MIB

### DESCRIPTION

The module `snmp_target_mib` implements the instrumentation functions for the SNMP-TARGET-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 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 files read are: `target_addr.conf` and `target_params.conf`.

`reconfigure(ConfDir) -> void()`

Types:

`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-TARGET-MIB, after this function has been called, is the data 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 , 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 files read are: `target_addr.conf` and `target_params.conf`.

`set_target_engine_id(TargetAddrName, EngineId) -> boolean()`

Types:

`TargetAddrName = string()`
`EngineId = string()`

Changes the enigne id for a target in the `snmpTargetAddrTable`. If notifications are sent as Inform requests to a target, its engine id must be set.

`add_addr(Name, Ip, Port, Timeout, Retry, TagList, Params, EngineId, TMask, MMS) -> Ret`

Types:

`Name = string()`
`Ip = [integer()], length 4`
`Port = integer()`
`Timeout = integer()`
`Retry = integer()`
`TagList = string()`
`ParamsName = string()`
`EngineId = string()`
`TMask = string(), length 0 or 6`
`MMS = integer()`
`Ret = {ok, Key} | {error, Reason}`
`Key = term()`
`Reason = term()`

Adds a target address definition to the agent config. Equivalent to one line in the `target_addr.conf` file.

`delete_addr(Key) -> Ret`

Types:

`Key = term()`
`Ret = ok | {error, Reason}`
`Reason = term()`

Delete a target address definition from the agent config.

`add_params(Name, MPModel, SecModel, SecName, SecLevel) -> Ret`

Types:

`Name = string()`
`MPModel = v1 | v2c | v3`
`SecModel = v1 | v2c | usm`
`SecName = string()`
`SecLevel = noAuthNoPriv | authNoPriv | authPriv`
`Ret = {ok, Key} | {error, Reason}`
`Key = term()`
`Reason = term()`

Adds a target parameter definition to the agent config. Equivalent to one line in the `target_params.conf` file.

`delete_params(Key) -> Ret`

Types:

`Key = term()`
`Ret = ok | {error, Reason}`
`Reason = term()`

Delete a target parameter definition from the agent config.
