[manager] When information from an unknown agent is received, - it was previously delivered to the default user via calls to all - the functions of the callback API depending on the info type - (pdu, trap, report or inform). - The problem was that the TargetName argument was useless - in this case (only an already known agent has a known/valid - TargetName, but the TargetName used in these calls - was generated "on the fly").

-

This has now been changed so that when a message is received - from an unknown agent, then only - handle_agent - (for the default user) is called, but now this call also has a - Type argument, which is - pdu | trap | report | inform, depending on what kind of - message was actually received, thus making it possible for the - user to properly analyze the data received.

[manager] A request for an oid of type BITS was actually - returned as OCTET STRING.

-

Values of type BITS are encoded as OCTET STRING, - which makes it impossible for the decoder to know that - they should really be of type BITS. - Instead, this has to be done higher up in the stack, where - there is knowledge of the MIB (assuming that the mib has - been loaded, there is info about the type of the mibentry).

-

This problem has now been fixed, but requires that the MIB - defining this mib-entry is loaded!

-

The utility function - oid_to_type - has been added, for debug purpose.

-

The utility function(s) - octet_string_to_bits - and - bits_to_octet_string - has also been added. These can be used if the user prefers to - handle the conversion on their own.

Per Hedeland

Own Id: OTP-7735

- -
- - -

[manager] A major flaw was discovered with the agent handling.

-

First, TargetName was never used as intended, as a unique - identifier for the target (agent in this case).

-

Second, TargetName had a default value, which meant - that several agents could have the same TargetName, causing - unpredictable behaviour in the manager.

-

Third, EngineID was not a mandatory config option and had - furthermore also a default value.

- -

These problems has been solved in the following way:

-

First, a new set of api functions has been introduced (and documented): - register_user/4, - register_user_monitor/4, - register_agent/3, - unregister_agent/2, - agent_info/2, - update_agent_info/4, - sync_get/3,4,5,6, - async_get/3,4,5,6, - sync_get_next/3,4,5,6, - async_get_next/3,4,5,6, - sync_set/3,4,5,6, - async_set/3,4,5,6, - sync_get_bulk/5,6,7,8 and - async_get_bulk/5,6,7,8 - that all use TargetName (and not, as previously, Addr - and Port) to identify the agent (also the return value of - which_agents has - been changed).

-

Second, for backward compatibility, the old functions still - exist, but are no longer documented and are now wrappers for the - new functions, including erroneous default value for EngineID and - all. The TargetName is however generated from the provided - Addr, Port and Version config options.

-

Third, the behaviour of the - SNMP manager user has - been changed to reflect this, i.e. - handle_pdu/4, - handle_trap/3, - handle_inform/3, - handle_report/3 - and the return-value of - handle_agent/4. - The old (non-documented) callback-functions (using Addr and Port) - will still be called if the agent was registered using the old - registration functions.

[manager] A request for an oid of type BITS was actually + returned as OCTET STRING.

+

Values of type BITS are encoded as OCTET STRING, + which makes it impossible for the decoder to know that + they should really be of type BITS. + Instead, this has to be done higher up in the stack, where + there is knowledge of the MIB (assuming that the mib has + been loaded, there is info about the type of the mibentry).

+

This problem has now been fixed, but requires that the MIB + defining this mib-entry is loaded!

+

The utility function + oid_to_type + has been added, for debug purpose.

+

The utility function(s) + octet_string_to_bits + and + bits_to_octet_string + has also been added. These can be used if the user prefers to + handle the conversion on their own.

+ + +

[manager] A major flaw was discovered with the agent handling.

+

First, TargetName was never used as intended, as a unique + identifier for the target (agent in this case).

+

Second, TargetName had a default value, which meant + that several agents could have the same TargetName, causing + unpredictable behaviour in the manager.

+

Third, EngineID was not a mandatory config option and had + furthermore also a default value.

+ +

These problems has been solved in the following way:

+

First, a new set of api functions has been introduced (and documented): + register_user/4, + register_user_monitor/4, + register_agent/3, + unregister_agent/2, + agent_info/2, + update_agent_info/4, + sync_get/3,4,5,6, + async_get/3,4,5,6, + sync_get_next/3,4,5,6, + async_get_next/3,4,5,6, + sync_set/3,4,5,6, + async_set/3,4,5,6, + sync_get_bulk/5,6,7,8 and + async_get_bulk/5,6,7,8 + that all use TargetName (and not, as previously, Addr + and Port) to identify the agent (also the return value of + which_agents has + been changed).

+

Second, for backward compatibility, the old functions still + exist, but are no longer documented and are now wrappers for the + new functions, including erroneous default value for EngineID and + all. The TargetName is however generated from the provided + Addr, Port and Version config options.

+

Third, the behaviour of the + SNMP manager user has + been changed to reflect this, i.e. + handle_pdu/4, + handle_trap/3, + handle_inform/3, + handle_report/3 + and the return-value of + handle_agent/4. + The old (non-documented) callback-functions (using Addr and Port) + will still be called if the agent was registered using the old + registration functions.
