# snmp_community_mib

### MODULE

snmp_community_mib

### MODULE SUMMARY

Instrumentation Functions for SNMP-COMMUNITY-MIB

### DESCRIPTION

The module `snmp_community_mib` implements the instrumentation functions for the SNMP-COMMUNITY-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 reason `configuration_error`.

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

The configuration file read is: `community.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-COMMUNITY-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 reason `configuration_error`.

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

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

`add_community(Idx, CommName, SecName, CtxName, TransportTag) -> Ret`

Types:

`Idx = string()`
`CommName = string()`
`SecName = string()`
`CtxName = string()`
`TransportTag = string()`
`Ret = {ok, Key} | {error, Reason}`
`Key = term()`
`Reason = term()`

Adds a community to the agent config. Equivalent to one line in the `community.conf` file.

`delete_community(Key) -> Ret`

Types:

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

Delete a community from the agent config.
