In an embodiment, a method comprises initiating a monitoring session for a communication path including creating and storing monitoring session state data; sending, to a first responder computer of the communication path, a first request to initiate a first state servlet that is configured to monitor continuously during the monitoring session one or more characteristics of one or more processes that the first responder computer may perform; sending, to the first responder computer, monitoring instructions to monitor the one or more characteristics of the one or more processes; while the monitoring session is active and the first responder computer is in the communication path, receiving and collecting monitored information from the first responder computer; in response to determining that the first responder computer is not in the communication path or that the monitoring session has become inactive, automatically and autonomously ending the monitoring session.

Continuous autonomous monitoring of systems along a path

A method is disclosed for transmitting system management requests to computer systems along a network path using a network control protocol, such as RSVP. For example, an originating node may send a single system management request along a path to a destination node using a network control protocol. Each computer system along the network path may analyze the network control protocol message to determine whether the message contains a system management request. If a system management request is found in the message, the computer system may perform the system management function identified in the request, and respond to it.

Performing path-oriented systems management

The network device is described that comprises an allocator to adaptively allocate respective event message rate limits to client network devices that is in communication with an event-based system logging server to send event messages to the logging server for processing. The adaptively allocated event message rate limits are communicated to the client network devices so that limiting of a global rate of event messages received by the logging server comprises limiting the respective rates at which the client network devices can transmit event messages to the logging server. Measurement of respective event message rates comprises a count of event messages actually received by the logging server from the corresponding client device within a defined time window.

Adaptive cross-network message bandwidth allocation by message servers

A method and apparatus for self-monitoring to identify an occurrence of a threshold and rebooting in response to the occurrence of the threshold is provided. In an embodiment, a data processing apparatus comprises one or more processors; logic coupled to the one or more processors and comprising one or more stored sequences of instructions which, when executed by one or more processors, cause the one or more processors to obtain a threshold associated with the apparatus; self-monitor the apparatus to identify an occurrence of the threshold; and self-reboot the apparatus responsive to the occurrence of the threshold.

Self-restarting network devices

A method is provided in one example and includes verifying a storage capacity of a network element coupled to an end device over a network connection. The method also includes executing script provided in the network element, which is configured for exchanging packets in a network environment. The script initiates a collection of data being retrieved from the end device. The data can be Fault, Configuration, Accounting, Performance, and Security (FCAPS) data associated with the end device. The data collected from the end device is communicated to a next destination.

System and method for providing a script-based collection for devices in a network environment

In one embodiment, a network device is described as including a rate monitor to monitor an actual individual message rate of event messages sent from each one of a plurality of sending devices operatively in communication with the network device, an allocator to allocate an individual message rate limit to each of the plurality of sending devices, and a communication module to communicate a rate limit instruction to at least one of the sending devices, the rate limit instruction to limit the transmission rate of event messages.

Techniques for system (syslog) messages are provided. As syslog messages are generated a dual sequence number is maintained for each syslog message. The first sequence number is consistent for each syslog message and represents a total number of syslog messages received. The second sequence number is maintained as a total message count for a specific session for which a syslog message is assigned.

Techniques for sequencing system log messages

In an embodiment, a data processing system comprises a repository configured to store a plurality of event message definitions for error messages, syslog messages, or other notification messages that may be emitted by one or more managed network elements; event annotation logic coupled to the data repository and configured to receive and store one or more annotations to each of the event message definitions, wherein each of the annotations specifies event context information to be collected in the managed network elements when an associated event message occurs; event forensics definitions generator logic coupled to the event annotation logic and configured to generate an event forensics definitions file capable of interpretation by one or more managed network elements and comprising event type identifiers and context information identifiers for context information to be collected, and configured to cause distributing the event forensics definitions file to the one or more managed network elements.

Adaptively collecting network event forensic data

A network device and a method for monitoring operational messages is described. The method comprises monitoring an occurrence of an operational message of the network device, and storing dynamic context information at the time that the operational message occurred. The stored dynamic context information is then associated with the operational message. The operational message (e.g., a syslog message) may be stored together with the dynamic context information in a metalog memory and may comprise a snapshot of a procedure stack, the procedure stack including information indicative of a sequence of procedure invocations.

System diagnostics with dynamic contextual information of events

An approach for propagating changes from a database to a client includes providing to the client a copy of a portion of the database, wherein the portion of the database contains a first data item. An updated value of the first data item is generated that reflects the application of a plurality of changes to the first data item. The updated value of the first data item is provided to the client with operator data that indicates one or more operations to be performed to update the copy of the portion of the database at the client with the updated value of the first data item. As used herein, the term 'data item' may refer to any type of data. For example, in the context of database systems, a data item may be an individual value, a database record containing several values, e.g., a row, a database table, or a group of database tables.
