APPLICATION SUMMARY

The SNMP Application

DESCRIPTION

This chapter describes the snmp application in OTP. The SNMP application provides the following services:

• a multilingual extensible SNMP agent
  
• a MIB compiler
  
• a simple manager
  

Configuration

The following configuration parameters are defined for the SNMP application. Refer to application(3) for more information about configuration parameters.

audit_trail_log = false | write_log | read_write_log <optional>

Specifies if an audit trail log should be used. The disk_log module is used to maintain a wrap log. If write_log is specified, only set requests are logged. If read_write_log, all requests are logged. Default is false.


audit_trail_log_dir = string() <optional>

Specifies where the audit trail log should be stored. If audit_trail_log specifies that logging should take place, this parameter must be defined.


audit_trail_log_size = {MaxBytes, MaxFiles} <optional>

Specifies the size of the audit trail log. This parameter is sent to disk_log. If audit_trail_log specifies that logging should take place, this parameter must be defined.


bind_to_ip_address = bool() <optional>

If true the agent binds to the agent IP adress. If false the agent listens on any IP address on the host where it is running. Default is false.


force_config_load = bool() <optional>

If true the configuration files are re-read during startup, and the contents of the configuration database ignored. Thus, if true, changes to the configuration database are lost upon reboot of the agent. Default is false.


no_reuse_address = bool() <optional>

If true the agent does not specify that the IP and port address should be reusable. If false the agent the address is set to reusable. Default is false.


snmp_agent_type = master | sub <optional>

If master, one master agent is started. Otherwise, no agents are started. Default is master.


snmp_config_dir = string() <mandatory>

Defines where the SNMP configuration files and the compiled master agent MIB files are stored.


snmp_db_dir = string() <mandatory>

Defines where the SNMP internal db files are stored.


snmp_master_agent_mibs = [string()] <optional>

Specifies a list of MIB names and defines which MIBs are initially loaded into the SNMP master agent. These MIBs are loaded from snmp_config_dir.


snmp_multi_threaded = bool() <optional>

If true, the agent is multi-threaded, with one thread for each get request. Default is false.


snmp_priority = atom() <optional>

Defines the Erlang priority for all SNMP processes. Default is normal.


v1 = bool() <optional>

Defines if the agent shall speak SNMPv1. Default is true.


v2 = bool() <optional>

Defines if the agent shall speak SNMPv2c. Default is true.


v3 = bool() <optional>

Defines if the agent shall speak SNMPv3. Default is true.
