Category: Web and Application Servers

Description: Manages World Wide Web services (HTTP and FTP servers/proxies), providing service information, protocol statistics, and document access counters.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring WWW-MIB with a free 30-day trial of IPNetwork Monitor.

What Is WWW-MIB?

WWW-MIB is a vendor-neutral, IETF standards-based MIB module used to monitor 'Document Transfer Protocol' services such as HTTP and FTP servers and proxies. It exposes a service table describing each configured web/FTP service instance -- its protocol, name, type, description, and administrative contact -- along with operational status and summary statistics objects. It is used to monitor the software-service status of a device running such services: whether the service is up (wwwServiceOperStatus), when it was started (wwwServiceStartTime), and when its configuration last changed (wwwServiceLastChange), essentially tracking service availability rather than hardware sensors. It has no significant dependency on other MIBs beyond standard SNMPv2-SMI/SNMPv2-CONF conventions, though it is conceptually related to other IETF application-layer service MIBs. It is typically deployed on any general-purpose server or network appliance running HTTP or FTP services that an operator wants visible to a standards-based SNMP management system. Engineers implementing or auditing this functionality typically reference the WWW-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in WWW-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

vendor-neutral, standards-based MIB, not tied to a specific manufacturer
any server or network appliance running HTTP/FTP services

Monitoring Examples

An administrator would poll wwwServiceTable/wwwServiceEntry, keyed by wwwServiceIndex, to see each configured HTTP or FTP service's wwwServiceProtocol, wwwServiceName, and wwwServiceOperStatus. If wwwServiceOperStatus for a given entry unexpectedly shows 'down' while wwwServiceLastChange shows a recent timestamp, that indicates the web/FTP service just failed or was reconfigured, prompting investigation. The wwwSummaryTable would additionally be checked for aggregate protocol statistics across all configured services on the device.

What Can Be Monitored

web/FTP service operational status
service start time
service configuration last-change time
service protocol/type/name
aggregate service summary statistics

How to Use in IPNetwork Monitor

Example using wwwSummaryInRequests OID:

Select a device implementing WWW-MIB 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 wwwSummaryInRequests into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of requests successfully received. 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.

TIK wwwDocCtrlLastNLock	1.3.6.1.2.1.65.1.3.1.1.2	TimeTicks	read-write	This object allows a manager to lock the wwwDocLastNTable in order to retrieve the wwwDocLastNTable in a consistent state. The agent is expected to take a snapshot of the wwwDocLastNTable when it is locked and to continue updating the real wwwDocLastNTable table so that recent information is available as soon as the wwwDocLastNTable is unlocked again. Setting this object to a value greater than 0 will lock the table. The timer ticks backwards until it reaches 0. The table unlocks automatically once the timer reaches 0 and the timer stops ticking. A manager can increase the timer to request more time to read the table. However, any attempt to decrease the timer will fail with an inconsistentValue error. This rule ensures that multiple managers can simultaneously lock and retrieve the wwwDocLastNTable. Note that managers must cooperate in using wwwDocCtrlLastNLock. In particular, a manager MUST not keep the wwwDocLastNTable locked when it is not necessary to finish a retrieval operation.
U32 wwwDocCtrlBuckets	1.3.6.1.2.1.65.1.3.1.1.3	Unsigned32	read-write	The maximum number of buckets maintained by the agent before the oldest bucket is deleted. The buckets are used to populate the wwwDocAccessTopNTable and the wwwDocBytesTopNTable. The time interval captured in each bucket can be configured by setting the wwwDocCtrlBucketTimeInterval object.
NUM wwwDocCtrlBucketTimeInterval	1.3.6.1.2.1.65.1.3.1.1.4	TimeInterval	read-write	The time interval after which a new bucket is created. Changing this object has no effect on existing buckets.
U32 wwwDocCtrlTopNSize	1.3.6.1.2.1.65.1.3.1.1.5	Unsigned32	read-write	The maximum number of entries shown in the wwwDocAccessTopNTable and the wwwDocBytesTopNTable. Changing this object has no effect on existing buckets.
wwwDocLastNTable	1.3.6.1.2.1.65.1.3.2		not-accessible	The table which logs the last N access attempts.
wwwDocLastNEntry	1.3.6.1.2.1.65.1.3.2.1		not-accessible	An entry which describes a recent access attempt.
U32 wwwDocLastNIndex	1.3.6.1.2.1.65.1.3.2.1.1	Unsigned32	not-accessible	An arbitrary monotonically increasing integer number used for indexing the wwwDocLastNTable. The first document accessed appears in the table with this index value equal to one. Each subsequent document is indexed with the next sequential index value. The Nth document accessed will be indexed by N. This table presents a sliding window of the last wwwDocCtrlLastNSize documents accessed. Thus, entries in this table will be indexed by N-wwwDocCtrlLastNSize thru N if N > wwwDocCtrlLastNSize and 1 thru N if N <= wwwDocCtrlLastNSize. The wwwDocCtrlLastNLock attribute can be used to lock this table to allow the manager to read its contents.
WWW wwwDocLastNName	1.3.6.1.2.1.65.1.3.2.1.2	WwwDocName	read-only	The name of the document for which access was attempted.
DAT wwwDocLastNTimeStamp	1.3.6.1.2.1.65.1.3.2.1.3	DateAndTime	read-only	The date and time of the last attempt to access this document.

WWW wwwDocLastNResponseType	1.3.6.1.2.1.65.1.3.2.1.5	WwwResponseType	read-only	The protocol response type which was sent to the client as a result of this attempt to access a document. This object contains the type of the primary response if there were multiple responses to a single request.
STR wwwDocLastNStatusMsg	1.3.6.1.2.1.65.1.3.2.1.6	Utf8String	read-only	This object contains a human readable description of the reason why the wwwDocLastNResponseType was returned to the client. This object defines the implementation-specific reason if the value of wwwDocLastNResponseType indicates an error. For example, this object can indicate that the requested document could not be transferred due to a timeout condition or the document could not be transferred because a 'soft link' pointing to the document could not be resolved.
U32 wwwDocLastNBytes	1.3.6.1.2.1.65.1.3.2.1.7	Unsigned32	read-only	The number of content bytes that were returned as a result of this attempt to access a document.
wwwDocBucketTable	1.3.6.1.2.1.65.1.3.3		not-accessible	This table provides administrative summary information for the buckets maintained per WWW service.
wwwDocBucketEntry	1.3.6.1.2.1.65.1.3.3.1		not-accessible	An entry which describes the parameters associated with a particular bucket.
U32 wwwDocBucketIndex	1.3.6.1.2.1.65.1.3.3.1.1	Unsigned32	not-accessible	An arbitrary monotonically increasing integer number used for indexing the wwwDocBucketTable. The index number wraps to 1 whenever the maximum value is reached.

U32 wwwDocBucketDocuments	1.3.6.1.2.1.65.1.3.3.1.4	Unsigned32	read-only	The total number of different documents for which access was attempted this this WWW service during the time interval over which this bucket was created.
U32 wwwDocBucketBytes	1.3.6.1.2.1.65.1.3.3.1.5	Unsigned32	read-only	The total number of content bytes which were transferred from this WWW service during the time interval over which this bucket was created.
wwwDocAccessTopNTable	1.3.6.1.2.1.65.1.3.4		not-accessible	The table of the most frequently accessed documents in a given bucket. This table is sorted by the column wwwDocAccessTopNAccesses. Entries having the same number of accesses are secondarily sorted by wwwDocAccessTopNBytes. Entries with the same number of accesses and the same number of bytes will have an arbitrary order.
