According to one or more embodiments of the disclosure, techniques herein provide for auto discovery of network proxies. In particular, in one embodiment, a controller in a computer network receives, from both source devices and destination devices, corresponding Transmission Control Protocol/Internet Protocol (TCP/IP) information and associated transaction identifiers (IDs) for packets sent by the source devices and for packets received at the destination devices. The controller may then correlate particular source TCP/IP information to particular destination TCP/IP information based on associated transaction IDs being the same, and can compare the correlated source TCP/IP information and destination TCP/IP information in order to determine whether a proxy device exists (e.g., and which particular type of proxy device exists) between the source device and the destination device.

Auto discovery of network proxies

In one embodiment, an agent process produces synthetic packet traffic and iteratively performs a sub-process that determines isolated network segments of the communication channel between intermediate nodes and computes a set of network metrics for the isolated network segments based at least in part on incrementing TTL expiry error data points. The sub-process also encapsulates, for inclusion within the next packet to be sent, a list of intermediate node IDs along the communication channel up to a latest received node ID and computed sets of network metrics for respective network segments. The agent process may then generate, upon termination of the sub-process, a report, the report including the list of intermediate node IDs along the communication channel up to a latest received node ID and computed sets of network metrics for respective network segments.

Isolation of network segments affecting application performance

A cluster analysis feature is provided to monitor and troubleshoot infrastructure issues impacting a distributed business application. Performance trends of one or more tiers of applications may be monitored, analyzed, and reported. By monitoring and reporting performance issues for tiers of applications, valuable time is saved from to individually go through each application individually. Agents installed on individual applications may monitor the performance of applications, collect metrics, aggregate the metrics and report the metrics back to a server. Clustering algorithms may be used to cluster infrastructure metrics and then correlate those metrics with the application nodes using the same algorithms.

Application aware cluster monitoring

In one embodiment, a network agent, associated with an operating system of a computing device, tracks socket connection calls made by a plurality of cotenant processes on the computing device that share a common network transport between the computing device and a remote computing device. The network agent may then extract a process identification (ID) for the socket connection calls, the process ID identifying which particular cotenant process of the plurality of cotenant processes is making each particular socket connection call. While monitoring network metrics of network traffic flows over socket connections between the computing device and the remote computing device, the network agent may attribute given network metrics from particular socket connections to a corresponding cotenant process based on the correlated process ID for the socket connection. As such, the network agent may then report the network metrics as attributed to the corresponding cotenant processes.

Network visibility for cotenant processes

A system monitors applications and network flows used during the business transaction to determine distributed business transaction anomalies caused at least in part by network performance issues. A network flow associated with a business transaction is monitored by a network agent. The network agent may capture packets, analyze the packets and other network data to determine one or more baselines, and dynamically compare subsequent network flow performance to those baselines to determine an anomaly. When an anomaly in a network flow is detected, this information may be provided to a user along with other data regarding a business transaction that is utilizing the network flow. Concurrently with the network agent monitoring, application agents may monitor one or more applications performing the business transaction. The present system reports performance data for a business transaction in terms of application performance and network performance, all in the context of a distributed business transaction.

Network aware distributed business transaction anomaly detection

A system and method is disclosed for seamless network management monitoring when a device or Virtual Machine migrates. As part of a network management monitoring system and method, a separate distinct identifier is designated to each port and each device or VM being monitored. When a device is located a specific port a correlation between the distinct identifier of that port and the distinct identifier of the device is stored in a correlation table and monitored. Once this correlation changes, the network management monitoring system recognizes a migration has occurred and updates the correlation table to correlate the new port's distinct identifier with the device's distinct identifier. Parameters that were set up to be monitored for the device can then continue to be monitored at the new location.

Smart migration of monitoring constructs and data

A desired node is selected from a tree structure or list and then a number of levels from that node are displayed in a map. For edge nodes, the number of undisplayed links from that node is displayed. When another node is selected on the map, the number of levels is recalculated based on that node or the existing nodes remain and the desired level is additionally displayed from the selected node. Multiple nodes can be selected from the list, which may result in separated islands which join when an common node is displayed in each island. Filters can be applied to limit the number of nodes. The filtering may either remove nodes from the display or provide an indication of the number of undisplayed nodes meeting the filter and any displayed nodes meeting the filter. The technique can be used on most linked networks.
