Problems solved by technology
[0003] In particular, in some large networks, the diagnostic and monitoring traffic generated between a monitoring application and multiple monitors can be substantial
In addition to consuming network resources (i.e., bandwidth), heavy diagnostic traffic can cause critical "signals" to be drowned in routine non-critical "noise"
That said, it can be difficult to extract information from overloaded, partly Significant events and status information for network resources such as failures or mass failures
[0004] Furthermore, the type and granularity of information reported by traditional network monitors, while adequate for routine maintenance tasks such as load balancing, are often insufficient for diagnosing faults or other critical conditions within the network
Therefore, even though system administrators can spot critical resource monitor reports, often these reports do not contain enough information for in-depth diagnosis and troubleshooting

Embodiment Construction
[0011] The present invention meets the needs of computer network system management by automatically deploying dissolving monitors for network nodes reporting critical events or states. Digestion Monitor automatically collects detailed diagnostic, status and event information for detailed reporting to a monitoring application. This allows system administrators to more quickly discover critical network nodes and perform meaningful troubleshooting. Over time and in response to various conditions (as will be explained below), the resolution resource monitor sends fewer and fewer reports and finally stops functioning and is removed from the relevant network node, freeing the node resources it occupies. According to an exemplary embodiment of the present invention, detection of critical events / states, deployment and operation of resolution monitors, and removal of resolution monitors from deployed nodes are all automated.

A network monitoring application deploys conventional monitor applications to network nodes and receives diagnostic events from the monitors. In response to a monitor reporting a high severity event or condition, the monitor application automatically deploys a dissolving monitor to the network node that automatically ceases operation at the conclusion of a predetermined lifespan. The dissolving monitor automatically reports verbose diagnostic events to the monitoring application, including diagnostic events not reported by the conventional monitor. The dissolving monitor removes itself from the node at the end of its lifespan by freeing all resources of said node that it consumed. In some embodiments, the dissolving monitor reports diagnostic events with decreasing frequency prior to its dissolution. The dissolution of the dissolving monitor may be triggered by time since its deployment, performance and status of the monitored node, error or anomaly counts, or combinations thereof.
Description
technical background [0001] The present invention belongs to the field of computer network management, and in particular relates to a method for automatically monitoring key network nodes through a self-terminating monitor application. [0002] The increasing capacity and throughput of computer networking technologies has led to the deployment of very large and complex computer networks. As networks continue to grow in size and complexity, it becomes increasingly difficult to monitor the health and status of network elements and efficiently manage network resources. One known method of network monitoring and management is to configure a "monitor" for some or all of the network or computing resources (referred to herein as network "nodes") within the network. This traditional monitor is an autonomous application that monitors the status and performance of a node, sending event, status and / or diagnostic information to one or more monitoring applications. A single monitoring ap...
