snmpm
Interface functions to the SNMP toolkit manager
The module snmpm
contains interface functions to the
SNMP manager.
Common Data Types
The following data types are used in the functions below:
oid() = [byte()] - The oid() type is used to represent an ASN.1 OBJECT IDENTIFIER snmp_reply() = {error_status(), error_index(), varbinds()} error_status() = noError | atom() error_index() = integer() varbinds() = [varbind()] atl_type() = read | write | read_write target_name() = string() - Is a unique *non-empty* string vars_and_vals() = [var_and_val()] var_and_val() = {oid(), value_type(), value()} | {oid(), value()} value_type() = o ('OBJECT IDENTIFIER') | i ('INTEGER') | u ('Unsigned32') | g ('Unsigned32') | s ('OCTET SRING') | b ('BITS') | ip ('IpAddress') | op ('Opaque') | c32 ('Counter32') | c64 ('Counter64') | tt ('TimeTicks') value() = term()
Functions
monitor() -> Ref
Ref = reference()
Monitor the SNMP manager. In case of a crash, the calling (monitoring) process will get a 'DOWN' message (see the erlang module for more info).
demonitor(Ref) -> void()
Ref = reference()
Turn off monitoring of the SNMP manager.
notify_started(Timeout) -> Pid
Timeout = integer()
Pid = pid()
Request a notification (message) when the SNMP manager has started.
The Timeout
is the time the request is valid. The
value has to be greater then zero.
The Pid
is the process handling the supervision of the
SNMP manager start. When the manager has started a completion
message will be sent to the client from this process:
{snmpm_started, Pid}
. If the SNMP manager was not started
in time, a timeout message will be sent to the client:
{snmpm_start_timeout, Pid}
.
A client application that is dependent on the SNMP manager will use this function in order to be notified of when the manager has started. There are two situations when this is useful:
-
During the start of a system, when a client application could start prior to the SNMP manager but is dependent upon it, and therefor has to wait for it to start.
-
When the SNMP manager has crashed, the dependent client application has to wait for the SNMP manager to be restarted before it can reconnect.
The function returns the pid() of a handler process, that does the supervision on behalf of the client application. Note that the client application is linked to this handler.
This function is used in conjunction with the monitor function.
cancel_notify_started(Pid) -> void()
Pid = pid()
Cancel a previous request to be notified of SNMP manager start.
register_user(Id, Module, Data) -> ok | {error, Reason}
register_user(Id, Module, Data, DefaultAgentConfig) -> ok | {error, Reason}
Id = term()
Module = snmpm_user()
Data = term()
DefaultAgentConfig = [default_agent_config()]
default_agent_config() = {Item, Val}
Item = community | timeout | max_message_size | version | sec_model | sec_name | sec_level
Val = term()
Reason = term()
snmpm_user() = Module implementing the snmpm_user behaviour
Register the manager entity (=user) responsible for specific agent(s).
Module
is the callback module (snmpm_user behaviour) which
will be called whenever something happens (detected
agent, incoming reply or incoming trap/notification).
Note that this could have already been done as a
consequence of the node config. (see users.conf).
The argument DefaultAgentConfig
is used as default values when
this user register agents.
The type of Val
depends on Item
:
community = string() timeout = integer() | snmp_timer() max_message_size = integer() version = v1 | v2 | v3 sec_model = any | v1 | v2c | usm sec_name = string() sec_level = noAuthNoPriv | authNoPriv | authPriv

Val = term()
Data = term()
Reason = term()
snmpm_user() = Module implementing the snmpm_user behaviour
Register the monitored manager entity (=user) responsible for specific agent(s).
The process performing the registration will be monitored. Which means that if that process should die, all agents registered by that user process will be unregistered. All outstanding requests will be canceled.
Module

Val = term()
Reason = term()
Explicitly instruct the manager to handle this agent, with
UserId
as the responsible user.

TargetName
is a non-empty string,
uniquely identifying the agent.
The type of Val

is an opaque data structure passed on to
the net-if process. The net-if process included in this
application makes no use of this info, so the only use for it
in such a configuration (when using the built in net-if) would
be tracing.

Converts an Audit Trail Log to a readable text file.
OutFile
defaults to "./snmpm_log.txt".
LogName
defaults to "snmpm_log".
LogFile
defaults to "snmpm.log".
See snmp:log_to_txt
for more info.
change_log_size(NewSize) -> ok | {error, Reason}
NewSize = {MaxBytes, MaxFiles}
MaxBytes = integer()
MaxFiles = integer()
Reason = term()
Changes the log size of the Audit Trail Log. The application must be configured to use the audit trail log function. Please refer to disk_log(3) in Kernel Reference Manual for a description of how to change the log size.
The change is permanent, as long as the log is not deleted. That means, the log size is remembered across reboots.
set_log_type(NewType) -> {ok, OldType} | {error, Reason}
NewType = OldType = atl_type()
Reason = term()
Changes the run-time Audit Trail log type.
Note that this has no effect on the application configuration as defined by configuration files, so a node restart will revert the config to whatever is in those files.
This function is primarily useful in testing/debugging scenarios.
load_mib(Mib) -> ok | {error, Reason}
Mib = MibName
MibName = string()
Reason = term()
Load a Mib
into the manager. The MibName
is the
name of the Mib, including the path to where the compiled mib is
found. For example,
Dir = code:priv_dir(my_app) ++ "/mibs/", snmpm:load_mib(Dir ++ "MY-MIB").
unload_mib(Mib) -> ok | {error, Reason}
Mib = MibName
MibName = string()
Reason = term()
Unload a Mib
from the manager. The MibName
is the
name of the Mib, including the path to where the compiled mib is
found. For example,
Dir = code:priv_dir(my_app) ++ "/mibs/", snmpm:unload_mib(Dir ++ "MY-MIB").
which_mibs() -> Mibs
Mibs = [{MibName, MibFile}]
MibName = atom()
MibFile = string()
Get a list of all the mib's loaded into the manager.
name_to_oid(Name) -> {ok, Oids} | {error, Reason}
Name = atom()
Oids = [oid()]
Transform a alias-name to its oid.
Note that an alias-name is only unique within the mib, so when loading several mib's into a manager, there might be several instances of the same aliasname.
oid_to_name(Oid) -> {ok, Name} | {error, Reason}
Oid = oid()
Name = atom()
Reason = term()
Transform a oid to its aliasname.
oid_to_type(Oid) -> {ok, Type} | {error, Reason}
Oid = oid()
Type = atom()
Reason = term()
Retreive the type (asn1 bertype) of an oid.
backup(BackupDir) -> ok | {error, Reason}
BackupDir = string()
Backup persistent data handled by the manager.
BackupDir cannot be identical to DbDir.
info() -> [{Key, Value}]
Key = atom()
Value = term()
Returns a list (a dictionary) containing information about the manager. Information includes statistics counters, miscellaneous info about each process (e.g. memory allocation), and so on.
verbosity(Ref, Verbosity) -> void()
Ref = server | config | net_if | note_store | all
Verbosity = verbosity()
verbosity() = silence | info | log | debug | trace
Sets verbosity for the designated process. For the lowest
verbosity silence
, nothing is printed. The higher the
verbosity, the more is printed.
format_reason(Reason) -> string()
format_reason(Prefix, Reason) -> string()
Reason = term()
Prefix = integer() | string()
This utility function is used to create a formatted (pretty printable) string of the error reason received from either:
-
The
Reason
returned value if any of the sync/async get/get-next/set/get-bulk functions returns{error, Reason}
-
The
Reason
parameter in the handle_error user callback function.
Prefix
should either be an indention string
(e.g. a list of spaces) or a positive integer (which will be used
to create the indention string of that length).
