1. IntrodUCtion

A networked application is a realization of some well defined service

on one or more host computers that is Accessible via some network,

uses some network for its internal operations, or both.

There are a wide range of networked applications for which it is

appropriate to provide SNMP monitoring of their network usage. This

includes applications using both TCP/IP and OSI networking. This

document defines a MIB which contains the elements common to the

monitoring of any network service application. This information

includes a table of all monitorable network service applications, a

count of the associations (connections) to each application, and

basic information about the parameters and status of each

application-related association.

This MIB may be used on its own for any application, and for most

simple applications this will suffice. This MIB is also designed to

serve as a building block which can be used in conjunction with

application-specific monitoring and management. Two examples of this

are MIBs defining additional variables for monitoring a Message

Transfer Agent (MTA) service or a Directory Service Agent (DSA)

service. It is eXPected that further MIBs of this nature will be

specified.

This MIB does not attempt to provide facilities for management of the

host or hosts the network service application runs on, nor does it

provide facilities for monitoring applications that provide something

other than a network service. Host resource and general application

monitoring is handled by the Host Resources MIB at present;

development of an additional application MIB is currently underway in

the IETF.

3. The SNMPv2 Network Management Framework

The SNMPv2 Network Management Framework consists of seven major

components. They are:

o RFC1902 [1] which defines the SMI, the mechanisms used for

describing and naming objects for the purpose of management.

o RFC1903 [2] defines textual conventions for SNMPv2.

o RFC1904 [3] defines conformance statements for SNMPv2.

o RFC1905 [4] defines transport mappings for SNMPv2.

o RFC1906 [5] defines the protocol operations used for network

access to managed objects.

o RFC1907 [6] defines the Management Information Base for SNMPv2.

o RFC1908 [7] specifies coexistance between SNMP and SNMPv2.

The Framework permits new objects to be defined for the purpose of

experimentation and evaluation.

3.1. Object Definitions

Managed objects are accessed via a virtual information store, termed

the Management Information Base or MIB. Objects in the MIB are

defined using the subset of Abstract Syntax Notation One (ASN.1)

defined in the SMI. In particular, each object type is named by an

OBJECT IDENTIFIER, an administratively assigned name. The object type

together with an object instance serves to uniquely identify a

specific instantiation of the object. For human convenience, we

often use a textual string, termed the descriptor, to refer to the

object type.

4. Rationale for having a Network Services Monitoring MIB

Much effort has been expended in developing tools to manage lower

layer network facilities. However, relatively little work has been

done on managing application layer entities. It is neither efficient

nor reasonable to manage all ASPects of application layer entities

using only lower layer information. Moreover, the difficulty of

managing application entities in this way increases dramatically as

application entities become more complex.

This leads to a substantial need to monitor applications which

provide network services, particularly distributed components such as

MTAs and DSAs, by monitoring specific aspects of the application

itself. Reasons to monitor such components include but are not

limited to measuring load, detecting broken connectivity, isolating

system failures, and locating congestion.

In order to manage network service applications effectively two

requirements must be met:

(1) It must be possible to monitor a large number of components

(typical for a large organization).

(2) Application monitoring must be integrated into general network

management.

This specification defines simple read-only access; this is

sufficient to determine up/down status and provide an indication of a

broad class of operational problems.

4.1. General Relationship to Other MIBs

This MIB is intended to only provide facilities common to the

monitoring of any network service application. It does not provide

all the facilities necessary to monitor any specific application.

Each specific type of network service application is expected to have

a MIB of its own that makes use of these common facilities.

4.2. Restriction of Scope

The framework provided here is very minimal; there is a lot more that

could be done. For example:

(1) General network service application configuration monitoring

and control.

(2) Detailed examination and modification of individual entries in

service-specific request queues.

(3) Probing to determine the status of a specific request (e.g.

the location of a mail message with a specific message-id).

(4) Requesting that certain actions be performed (e.g. forcing an

immediate connection and transfer of pending messages to some

specific system).

All these capabilities are both impressive and useful. However,

these capabilities would require provisions for strict security

checking. These capabilities would also mandate a much more complex

design, with many characteristics likely to be fairly

implementation-specific. As a result such facilities are likely to

be both contentious and difficult to implement.

This document religiously keeps things simple and focuses on the

basic monitoring aspect of managing applications providing network

services. The goal here is to provide a framework which is simple,

useful, and widely implementable.

4.3. Configuration Information

This MIB attempts to provide information about the operational

aspects of an application. Further information about the actual

configuration of a given application may be kept in other places; the

applDirectoryName or applURL may be used to point to places where

such information is kept.

5. Application Objects

This MIB defines a set of general purpose attributes which would be

appropriate for a range of applications that provide network

services. Both OSI and non-OSI services can be accomodated.

Additional tables defined in extensions to this MIB provide

attributes specific to specific network services.

A table is defined which will have one row for each operational

network service application on the system. The only static

information held on the application is its name. All other static

information should be oBTained from various directory services. The

applDirectoryName is an external key, which allows an SNMP MIB entry

to be cleanly related to the X.500 Directory. In SNMP terms, the

applications are grouped in a table called applTable, which is

indexed by an integer key applIndex.

The type of the application will be determined by one or both of:

(1) Additional MIB variables specific to the applications.

(2) An association to the application of a specific protocol.

7. Changes made since RFC1565

The only changes made to this document since it was issued as RFC

1565 [11] are the following:

(1) applDescription and applURL fields have been added. These

fields are intended to identify and describe the application.

(2) A number of DESCRIPTION fields have been reWorded, hopefully

making them clearer.

(3) The new "quiescing" state has been added to applOperStatus.

(4) The prose about "dynamic single threaded processes" has been

removed -- it was simply too confusing.

(5) Various RFCreferences have been updated to refer to more

recent versions.

(6) The MIB has been renamed from APPLICATION-MIB to NETWORK-

SERVICES-MIB. This was done because an application MIB is now

under development within the IETF that provides very different

functionality from this MIB.

8. Acknowledgements

This document is a product of the Mail and Directory Management

(MADMAN) Working Group. It is based on an earlier MIB designed by S.

Kille, T. Lenggenhager, D. Partain, and W. Yeong. The Electronic

Mail Association's TSC committee was instrumental in providing

feedback on and suggesting enhancements to RFC1565 [11] that have

led to the present document.

10. Security Considerations

This MIB does not offer write access, and as such cannot be used to

actively attack a system. However, this MIB does provide passive

information about the existance, type, and configuration of

applications on a given host that could potentially indicate some

sort of vulnerability. Finally, the information MIB provides about

network usage could be used to analyze network traffic patterns.
