In this section describe the unique components that make up the scenario, +.. what each component provides and why it has been included in order +.. to communicate to the user the capabilities available in this scenario. + +This scenario deploys the High Availability OPNFV Cloud based on the +configurations provided in ha_nfv-kvm_ovs_bar_heat_ceilometer_scenario.yaml. +This yaml file contains following configurations and is passed as an +argument to deploy.py script + +* scenario.yaml:This configuration file defines translation between a + short deployment scenario name(os-nosdn-kvm_ovs_dpdk_bar-ha) and an actual + deployment scenario configuration file + (ha_nfv-kvm_nfv-ovs-dpdk_bar_heat_ceilometer_scenario.yaml) + +* deployment-scenario-metadata:Contains the configuration metadata like + title,version,created,comment. + +* stack-extensions:Stack extentions are opnfv added value features in form + of a fuel-plugin.Plugins listed in stack extensions are enabled and + configured. + +* dea-override-config: Used to configure the HA mode,network segmentation + types and role to node assignments. These configurations overrides + corresponding keys in the dea_base.yaml and dea_pod_override.yaml. + These keys are used to deploy multiple nodes(3 controllers,2 computes) + as mention below. + +* **Node 1**: This node has MongoDB and Controller roles. The controller + node runs the Identity service, Image Service, management portions of + Compute and Networking, Networking plug-in and the dashboard. The + Telemetry service which was designed to support billing systems for + OpenStack cloud resources uses a NoSQL database to store information. + The database typically runs on the controller node. + +* **Node 2**: This node has Controller and Ceph-osd roles. Ceph is a + massively scalable, open source, distributed storage system. It is + comprised of an object store, block store and a POSIX-compliant distributed + file system. Enabling Ceph, configures Nova to store ephemeral volumes in + RBD, configures Glance to use the Ceph RBD backend to store images, + configures Cinder to store volumes in Ceph RBD images and configures the + default number of object replicas in Ceph. + +* **Node 3**: This node has Controller role in order to achieve high + availability. + +* **Node 4**: This node has Compute role. The compute node runs the + hypervisor portion of Compute that operates tenant virtual machines + instances. By default, Compute uses KVM as the hypervisor. Collectd + will be installed on this node. + +* **Node 5**: This node has compute role. + +* dha-override-config:Provides information about the VM definition and + Network config for virtual deployment. These configurations overrides + the pod dha definition and points to the controller,compute and + fuel definition files. + +* os-nosdn-kvm_ovs_dpdk_bar-ha scenario is successful when all the 5 Nodes are + accessible, up and running. + +Scenario usage overview +---------------------------- +..

This should be an "introduction" to the userguide document, and explicitly link to it, +.. where the specifics of the features are covered including examples and API's + +After installation use of the scenario traffic on the private network will +automatically be processed by the upgraded DPDK datapath. + +Limitations, Issues and Workarounds +--------------------------------------- +..

Describe the specific features and how it is realised in the scenario in a brief manner +.. to ensure the user understand the context for the user guide instructions to follow. + +collectd is a daemon which collects system performance statistics periodically +and provides a variety of mechanisms to publish the collected metrics. It +supports more than 90 different input and output plugins. Input plugins +retrieve metrics and publish them to the collectd deamon, while output plugins +publish the data they receive to an end point. collectd also has infrastructure +to support thresholding and notification. + +Barometer has enabled the following collectd plugins: + +* *dpdkstat plugin*: A read plugin that retrieve stats from the DPDK extended + NIC stats API. + +* `ceilometer plugin`_: A write plugin that pushes the retrieved stats to + Ceilometer. It's capable of pushing any stats read through collectd to + Ceilometer, not just the DPDK stats. + +* *hugepages plugin*: A read plugin that retrieves the number of available + and free hugepages on a platform as well as what is available in terms of + hugepages per socket. + +* *RDT plugin*: A read plugin that provides the last level cache utilitzation and + memory bandwidth utilization + +* *Open vSwitch events Plugin*: A read plugin that retrieves events from OVS. + +* *mcelog plugin*: A read plugin that uses mcelog client protocol to check for + memory Machine Check Exceptions and sends the stats for reported exceptions + +All the plugins above are available on the collectd master, except for the +plugin as it's a python based plugin and only C plugins are accepted +by the collectd community. The ceilometer plugin lives in the OpenStack +repositories. + +Other plugins under development or existing as a pull request into collectd master: + +* *dpdkevents*: A read plugin that retrieves DPDK link status and DPDK + forwarding cores liveliness status (DPDK Keep Alive). + +* *Open vSwitch stats Plugin*: A read plugin that retrieve flow and interface + stats from OVS. + +* *SNMP Agent*: A write plugin that will act as a AgentX subagent that receives + and handles queries from SNMP master agent and returns the data collected + by read plugins. The SNMP Agent plugin handles requests only for OIDs + specified in configuration file. To handle SNMP queries the plugin gets data + from collectd and translates requested values from collectd's internal format + to SNMP format. Supports SNMP: get, getnext and walk requests. + +* *Legacy/IPMI*: A read plugin that reports platform thermals, voltages, + fanspeed, current, flow, power etc. Also, the plugin monitors Intelligent + Platform Management Interface (IPMI) System Event Log (SEL) and sends the + +**Plugins included in the Danube release:** + +* Hugepages +* Open vSwitch Events +* Ceilometer +* Mcelog + +collectd capabilities and usage +------------------------------------ +..
