One of the biggest operational concerns for IT Operations and Virtual Infrastructure (VI) administrators is the lack of visibility between the virtual and physical networking – VI administrators have no tools to trace network traffic tunneled in the overlay protocols (e.g. VXLAN) and troubleshoot connectivity issues in mixed virtual and physical networks. The lack of traceability leads to longer time to resolution, and unacceptably long network outages.
Network Health and Path Analytics App provides VI Administrators with the means of identifying failing or unstable elements in both virtual and physical parts of a network. For each network interface and each network device as a whole the App computes important vitality metrics such as health and failure risk scores and provides a visual indication of a network element’s condition.
Also the App enables VI Administrator to monitor tunneled network conversations between network peers by tracing paths in the network taken by data packets within the tunnels. VI Administrator can trace communications between individual VMs, VMs communicating with network hosts residing on a physical network, and VM communications tunneled in overlay protocols. While tracing network communications VI Administrator can see the network devices which relayed the traffic and the interfaces on these devices through which communication has occurred.
Network Health and Path Analytics Splunk App is powered by the NetFlow Logic’s NetFlow Integrator™ (NFI) flow analysis engine and the Network Operations Monitor NFI Module (NetOps). NFI is an analytical engine for all kinds of network flow data (NetFlow, IPFIX, sFlow, etc.). NFI receives network flow data provided by virtual and physical network devices (routers, switches, firewalls), applies multivariate analytical algorithms to the flow data and sends results of the analysis in a syslog format to Splunk Enterprise in Common Information Model (CIM) for visualization
