RE: [Syslog] MIB Issue #2: document terminology.
Hi,
[speaking as a contributor]
We have already submitted the protocol document.
If everybody else is satisfied the terminology is clear in that
document, with the minor fixes you have made), then I will not oppose
it simply moving forward.
I do want to make sure the descriptions in the mib document are
consistent with the protocol document, and clear and unambiguous for
MIB implementers, who may be different personnel than the syslog
implementers. I find the mib document to be too abstract in its
architecture and terminology, and that makes it confusing. I think the
MIB document should be written in terms of senders and receivers and
relays, and not in terms of entities.
I am not concerned about the naming in the MIB tables for Issue#2; I
will tackle that in issue#3.
I am attaching the pre-02 revision. I recommend people look at the 02
revision and compare it to a reasonably current revision (I used 08,
since that was before some of the massive restructuring of the MIB, so
it is closer to 02).
I find the background text in rev 02 much clearer than in rev 11.
I find "How this MIB Works" somewhat enlightening in rev 02; it talks
about sending to multiple message aggregators. While more detailed,
rev 11 does not explain the purpose of a syslogSystem group and how
this portion of the MIB works. I walk away from the current text in
How the MIB Works thinking "what did that say?"
I am not saying we should use the text from 02; it obviously does not
represent the current terminology either. But the text in 02 is
concrete enough that the reader (even I!) can grasp what is being
discussed - "All Syslog collectors for an individual entity can be
defined to use the same UDP port number, syslog facility, and maximum
severity level, or any and all of these can be defined on a per
collector basis."; rev 11 just says "The default configuration
parameters for the group of syslog entities" leaving me wondering
"syslog entities? What types of syslog entities? What sorts of default
configuration parameters? Why are default configuration parameters
needed?".
The current text does not describe any use cases for the information
provided in the MIB module. Maybe that is what is really missing from
this text.

Abstract
This memo provides a MIB module that can be used to configure which
syslog collectors or relays a syslog device will attempt to send
syslog messages to. In addition it defines objects that allow the
collection of statistics related to the generation of syslog messages.
And finally it provides a means for controlling the messages that
individual applications on a device will generate.

1. Introduction
This document defines a portion of the Management Information Base
(MIB) for use with management protocols in the Internet community.
In particular, it describes managed objects used for configuring and
monitoring the Syslog message logging facility on syslog devices.
2. The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2571 [RFC2571].
o Mechanisms for describing and naming objects and events for the
purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and described in
STD 16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC
1215 [RFC1215]. The second version, called SMIv2, is described
in STD 58, RFC 2578 [RFC2578], RFC 2579 [RFC2579] and RFC 2580
[RFC2580].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
described in STD 15, RFC 1157 [RFC1157]. A second version of the
SNMP message protocol, which is not an Internet standards track
protocol, is called SNMPv2c and described in RFC 1901 [RFC1901]
and RFC 1906 [RFC1906]. The third version of the message
protocol is called SNMPv3 and described in RFC 1906 [RFC1906],
RFC 2572 [RFC2572] and RFC 2574 [RFC2574].
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in STD 15, RFC 1157 [RFC1157]. A second set of
protocol operations and associated PDU formats is described in
RFC 1905 [RFC1905].
o A set of fundamental applications described in RFC 2573
[RFC2573] and the view-based access control mechanism described
in RFC 2575 [RFC2575].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC 2570 [RFC2570].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A
MIB conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine readable
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process. However, this loss of machine
readable information is not considered to change the semantics of the
MIB.
The MIB contained in this document uses SMIv2 and utilizes the
"RowStatus" textual convention. Implementors should carefully read
the definition of this textual convention.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
3. Background
In order to efficiently manage and debug larger and more complex
networks the ability to log messages to a centralized message
collector is a necessity.
Under this proposal, a widely adopted third party message aggregation
facility, Syslog, will be used to collect messages from entire sets
of network entities.
Possible implementations of these services in the managed entity
include:
Case 1:
App1 -->|
App2 -->| |-----| |--> SCL1
App3 -->|----| SDS |----|--> SCL2
App4 -->| |-----| |--> SCL3
AppN -->|
Case 2:
|------|
| SDS1 |----> SCL1
/|------|
App1 -->| /
App2 -->| / |------|
App3 -->|----| SDS2 |----> SCL2
App4 -->| \ |------|
AppN -->| \
\|------|
| SDS3 |----> SCL3
|------|
App: Application
SDS: Syslog Device Software
SCL: Syslog Collector
In the first case a single syslog priority filter, facility, and
UDP port are applied to all messages for all collectors. In this case
none of the respective leaves need to have write access to implement
this MIB.
In the second case each message is processed based upon the collector
that it is being forwarded to. In this case any or all of the
respective leaves can be implemented read-create to allow per
collector control of the message priority, facility, and/or UDP port.
The implementation in the second case has the advantage that in a
customer environment where the customer is logging "management"
messages to one collector a support engineer could configure the
entity to log "diagnostic" messages to another collector, without
having to reconfigure the first collector, or worry about the impact
of the "diagnostic" messages on that collector.
In the context of keeping statistics for dropped messages, the
application to syslog device software interface is considered
the upstream side, and the syslog device software to syslog collector
interface is considered the down stream side.
Message levels are ranked from 0 (emergency), to 7 (debug).
4. How this MIB works.
The purpose of the Syslog Device Configuration MIB is to allow
the SNMP configuration of individual network entities in relation
to the generation and logging of diagnostic messages.
Each network entity can log messages to a number of Syslog message
aggregators. Minimally, a message aggregator is defined by its IP
address. All Syslog collectors for an individual entity can be defined
to use the same UDP port number, syslog facility, and maximum severity
level, or any and all of these can be defined on a per collector basis.
In addition each network entity may support a number of applications
that can be configured to generate various levels of messages. The
entities will enumerate the applications that they support, the default
maximum message level that they will generate, and will allow the
adjustment of that message level if applicable.

8. Security Considerations
There are a number of management objects defined in this MIB that
have a MAX-ACCESS clause of read-write and/or read-create. Such
objects may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations.
SNMPv1 by itself is not a secure environment. Even if the network
itself is secure (for example by using IPSec), even then, there is no
control as to who on the secure network is allowed to access and
GET/SET (read/change/create/delete) the objects in this MIB.
It is recommended that the implementers consider the security
features as provided by the SNMPv3 framework. Specifically, the use
of the User-based Security Model RFC 2574 [RFC2574] and the View-
based Access Control Model RFC 2575 [RFC2575] is recommended.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, is properly
configured to give access to the objects only to those principals
(users) that have legitimate rights to indeed GET or SET
(change/create/delete) them.
