CDP events for identification of duplex or native VLAN mismatch errors and CDP neighbor monitoring.A table with routing events, route metrics, and alerts on route flapping.A list of routing protocols used in the network and the number of neighbors/adjacencies.Before you know it, you can have your custom dashboard and custom alerts firing when something is off. There are visualizations that will provide topology diagrams as well.

The following is a list of questions/searches you might ask of your switch and router data after you have a full inventory. Begin working each KPI individually and build out your dashboard. Start with evaluating switch and router features, document them and order them by priority. From there, you can focus your searches on the data that report on critical SLAs or metrics provided by those features. Spoiler alert, it’s UDP.Īs you develop your custom dashboard for IT infrastructure monitoring, begin with the features currently enabled on your switches and routers. TCP is also supported, but before making the final call, here’s a blog post written by one of our colleagues, Ryan Faircloth, who discusses the difference between TCP and UDP Syslog.

On the right, SC4C is running on a node that the edge devices are sending UDP Syslog to. On the left side of the diagram below, you see the traditional setup that leverages Syslog-NG and the Splunk Universal Forwarder (UF) to read and send that data to the indexers. Simply run SC4S on a Linux host and configure two files (essentially a startup file and an environmentals file). An all-in-one solution that is simple to deploy and configure. The official Splunk recommendation is to use Splunk Connect for Syslog (SC4S) as a turn-key method of collecting and sending Syslog to Splunk. This is well documented in the post (any many others). Enterprise organizations should be running a Syslog server environment per Splunk best practices. Although Splunk ingests all Syslog data coming from network infrastructure components (e.g., routers, switches, wireless controllers, etc.), the collection of Syslog is done one layer away. One of the main ideas here and in Jeff's post is Syslog.
