Description: Enterasys Networks MIB for retrieving and monitoring system diagnostic log messages on Enterasys products.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ENTERASYS-DIAGNOSTIC-MESSAGE-MIB?

The ENTERASYS-DIAGNOSTIC-MESSAGE-MIB is an Enterasys Networks (later Extreme Networks) enterprise MIB for retrieving system diagnostic log messages generated internally by the device's diagnostic subsystem. It exposes a summary count and change counter for diagnostic messages plus detailed tables recording each message's timestamp, type, summary text, associated firmware revision, and status. This is a direct software/hardware fault-monitoring tool: administrators poll it to detect new diagnostic events, which typically correspond to hardware self-test failures, firmware faults, or other internal error conditions, shortly after they occur, and the firmware-revision field helps correlate faults to a specific software build. It is a self-contained module within Enterasys's enterprise MIB tree, generally used alongside standard SNMP trap mechanisms for real-time alerting. It is deployed on Enterasys/Extreme Networks switches and routers in enterprise networks, where ENTERASYS-DIAGNOSTIC-MESSAGE-MIB SNMP monitoring is valuable for proactive fault detection via centralized diagnostic-log collection.

IPNetwork Monitor allows you to monitor SNMP objects defined in ENTERASYS-DIAGNOSTIC-MESSAGE-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Enterasys/Extreme Networks switches and routers

Monitoring Examples

An administrator would poll etsysDiagnosticMessageCount and etsysDiagnosticMessageChanges to detect that new diagnostic entries have appeared, then walk etsysDiagnosticMessageTable/etsysDiagnosticMessageEntry to read etsysDiagnosticMessageType, etsysDiagnosticMessageSummary, and etsysDiagnosticMessageStatus for each new message. A cluster of new messages referencing the same etsysDiagnosticMessageFWRevision could point to a firmware-specific fault worth escalating to the vendor.

What Can Be Monitored

diagnostic message count
diagnostic message type/summary
diagnostic message status
firmware revision at time of fault
diagnostic message timestamp

How to Use in IPNetwork Monitor

Example using etsysDiagnosticMessageCount OID:

Select an Enterasys Networks switch (legacy, later Extreme Networks)/router (diagnostic log messages) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type etsysDiagnosticMessageCount into the Find box to locate it in the OID tree, then select it and click OK. The number of messages logged on this entity since the beginning of time. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
etsysDiagnosticMessageMIB	1.3.6.1.4.1.5624.1.2.13			This MIB module defines a portion of the SNMP enterprise MIBs under the Enterasys enterprise OID pertaining to the retrieval of diagnostic messages.
etsysDiagnosticMessage	1.3.6.1.4.1.5624.1.2.13.1
C32 etsysDiagnosticMessageCountEx	1.3.6.1.4.1.5624.1.2.13.1.1	Counter32	read-only	The number of messages logged on this entity since the beginning of time. This value must be persistent. There should be no facility to clear this value.
C32 etsysDiagnosticMessageChanges	1.3.6.1.4.1.5624.1.2.13.1.2	Counter32	read-only	The number of changes to the message log since the last reboot. Changes should include, clearing the message log, deleting a message, and the logging of new messages.
etsysDiagnosticMessageTable	1.3.6.1.4.1.5624.1.2.13.1.3		not-accessible	This table lists a summary of the diagnostic messages stored on the managed entity.
etsysDiagnosticMessageEntry	1.3.6.1.4.1.5624.1.2.13.1.3.1		not-accessible	An entry describing a particular diagnostic message. Every message that is stored in non-volatile memory is required to appear in this table.
U32 etsysDiagnosticMessageIndex	1.3.6.1.4.1.5624.1.2.13.1.3.1.1	Unsigned32	not-accessible	A unique arbitrary identifier for this message. For stateless message log implementations it may be valid only while etsysDiagnosticMessageChanges remains unchanged.
DAT etsysDiagnosticMessageTime	1.3.6.1.4.1.5624.1.2.13.1.3.1.2	DateAndTime	read-only	The time and date that this message was stored.
STR etsysDiagnosticMessageType	1.3.6.1.4.1.5624.1.2.13.1.3.1.3	SnmpAdminString	read-only	A description of the type of message shown in this entry.
STR etsysDiagnosticMessageSummary	1.3.6.1.4.1.5624.1.2.13.1.3.1.4	SnmpAdminString	read-only	A brief summary of the diagnostic message.
STR etsysDiagnosticMessageFWRevision	1.3.6.1.4.1.5624.1.2.13.1.3.1.5	SnmpAdminString	read-only	The string representing the version of firmware running on the the managed entity at the time the message was stored.
BIT etsysDiagnosticMessageStatus	1.3.6.1.4.1.5624.1.2.13.1.3.1.6	Bits	read-only	A list of attributes associated with this message. Generally these attributes would be considered exceptional, but could potentially be extended to indicate any number of conditions.
etsysDiagnosticMessageDetails	1.3.6.1.4.1.5624.1.2.13.2
etsysDiagnosticMessageDetailsTable	1.3.6.1.4.1.5624.1.2.13.2.1		not-accessible	This table contains the complete diagnostic messages for entries in the etsysDiagnosticMessageSummaryTable. This allows a message of virtually unlimited length to be accessible via SNMP.
etsysDiagnosticMessageDetailsEntry	1.3.6.1.4.1.5624.1.2.13.2.1.1		not-accessible	An entry describing a particular fragment of a message.
U32 etsysDiagnosticMessageDetailsIndex	1.3.6.1.4.1.5624.1.2.13.2.1.1.1	Unsigned32	not-accessible	A unique arbitrary identifier for this message fragment. Ideally this index should have the values 1 - n, where 'n' is the number of message fragments. It, at a minimum, must be chosen such that the lexicographical ordering will allow the fragments to be assembled in the proper order.
STR etsysDiagnosticMessageDetailsText	1.3.6.1.4.1.5624.1.2.13.2.1.1.2	LongAdminString	read-only	The text that makes up a fragment of a message.
