- The document discusses Neutron L3 HA (VRRP) and summarizes a presentation given on the topic.
- Neutron L3 HA uses the VRRP protocol to provide redundancy and failover for virtual routers across multiple network nodes. A heartbeat network is created for each tenant using their tenant network.
- When a router is created, a heartbeat port and interface are created on each L3 agent node using the tenant's heartbeat network to enable communication between the agents for the VRRP implementation.

Fluent-plugin-dstat is a plugin for the Fluentd logging system that allows it to monitor system resources in real-time by parsing output from the dstat system monitoring tool. It can be configured to capture CPU, disk, network, and process statistics from servers and send the data to MongoDB for centralized cluster monitoring and display on a web-based client using WebGL rendering. The demo configuration shows Fluentd running on master and slave servers to collect dstat metrics and send them to a central MongoDB database for real-time monitoring of resources across a cluster.
