Sudo apt-get update & sudo apt-get install influxdb # Update the repositories, and install influx # Trust the Influx GPG keyĮcho "deb $ stable" | sudo tee /etc/apt//influxdb.list The installation for Influx is pretty straight forward, and taken direct from their documentation pages. The host OS for my collector is Ubuntu 18.04.03. The devices I’m going to be streaming the data from is a Cisco CSR1000V a Cisco XRv, and a Juniper vMX. In this blog post I’m going to walk through setting up Telegraf to ingest telemetry data, Influx to store the data, and Grafana to display the data. This reduces load on the control plane while allowing more fine grained statistics to be gathered. This alternative method of data generation allows a lot of the processing to be pushed down to the line cards. The metrics that an operator are interested in are set up in advance, and then the devices send their metrics to the collector in regular intervals without any further requests. Streaming telemetry overcomes this by operating a subscription model. Due to this, there is a limitation on the granularity of the statistics that can be collected. As the number of metrics you with to measure increases, this places an increased burden on the control plane. All statistics need to be collected and provided by the routing engine. While this has worked fine for many years, it has its limitations. This can provide lots of in depth statistics about the health and status of the network. The current methods of getting statistics out of the network equipment is to use SNMP.
