This will generate some code from the yang models. +* Modify the model yang file under the model project. +* Follow the comments in the generated provider class to wire your new provider into the generated +code. +* Modify the generated provider model to respond to and handle the yang model. Depending on what +you added to your model you may need to inherit additional interfaces or make other changes to +the provider model. + +Generated Bundles +====================== +* model + - Provides the yang model for your application. This is your primary northbound interface. +* provider + - Provides a template implementation for a provider to respond to your yang model. +* features + - Defines a karaf feature. If you add dependencies on third-party bundles then you will need to + modify the features.xml to list out the dependencies. +* installer + - Bundles all of the jars and third party dependencies (minus ODL dependencies) into a single + .zip file. + +Usage +====================== +## Purpose +The purpose of this ODL feature is to support geo-redundancy through a series of ODL integrated health checks and tools. + +## Properties File +On initialization gr-toolkit expects to find a file named ```gr-toolkit.properties``` located in the ```SDNC_CONFIG``` directory. The properties file should contain: +- ```akka.conf.location``` + - The path to the akka.conf configuration file. +- ```adm.useSsl``` + - true/false; Determines whether or not to use http or https when making requests to the Admin Portal. +- ```adm.fqdn``` + - The FQDN or url of the site's Admin Portal. +- ```adm.healthcheck``` + - The url path of the Admin Portal's health check page. +- ```adm.port.http``` + - The HTTP port for the Admin Portal. +- ```adm.port.ssl``` + - The HTTPS port for the Admin Portal. +- ```controller.credentials``` + - username:password; The credentials used to make requests to the ODL controller. +- ```controller.useSsl``` + - true/false; Determines whether or not to use http or https when making requests to the controller. +- ```controller.port.http``` + - The HTTP port for the ODL Controller. +- ```controller.port.ssl``` + - The HTTPS port for the ODL Controller. +- ```controller.port.akka``` + - The port used for Akka communications on the ODL Controller. +- ```mbean.cluster``` + - The Jolokia path for the Akka Cluster MBean. +- ```mbean.shardManager``` + - The Jolokia path for the Akka ShardManager MBean. +- ```mbean.shard.config``` + - The Jolokia path for the Akka Shard MBean. This should be templated to look like ```/jolokia/read/org.opendaylight.controller:Category=Shards,name=%s,type=DistributedConfigDatastore```. GR Toolkit will use this template with information pulled from the Akka ShardManager MBean. +- ```site.identifier``` + - A unique identifier for the site the ODL Controller resides on. + +## Site Identifier +Returns a unique site identifier of the site the ODL resides on. + +> ### Input: None +> +> ### Output +> ```json +> { +> "output": { +> "id": "UNIQUE_IDENTIFIER_HERE", +> "status": "200" +> } +> } +> ``` + +## Admin Health +Returns HEALTHY/FAULTY based on whether or not a 200 response is received from the Admin Portal's health check page. + +> ### Input: None +> +> ### Output +> ```json +> { +> "output": { +> "status": "200", +> "health": "HEALTHY" +> } +> } +> ``` + +## Database Health +Returns HEALTHY/FAULTY based on if DbLib can obtain a writeable connection from its pool. + +> ### Input: None +> +> ### Output +> ```json +> { +> "output": { +> "status": "200", +> "health": "HEALTHY" +> } +> } +> ``` + +## Cluster Health +Uses Jolokia queries to determine shard health and voting status.

A FAULTY Admin Portal or Database health status will constitute a FAULTY site; in a 3 ODL node configuration, 2 FAULTY nodes constitutes a FAULTY site. If any portion of the health check registers as FAULTY, the entire site will be designated as FAULTY. In a 6 node configuration these health checks are performed cross site as well. + +> ### Input: None +> +> ### Output +> ```json +> { +> "output": { +> "sites": [ +> { +> "id": "SITE_1", +> "role": "ACTIVE", +> "health": "HEALTHY" +> }, +> { +> "id": "SITE_2", +> "role": "STANDBY", +> "health": "FAULTY" +> } +> ], +> "status": "200" +> } +> } +> ``` + +## Halt Akka Traffic +Places rules in IP Tables to block Akka traffic to/from a specific node on a specified port. + +> ### Input: +> ```json +> { +> "input": { +> "node-info": [ +> { +> "node": "your.odl.node", +> "port": "2550" +> } +> ] +> } +> } +> ``` +> +> ### Output +> ```json +> { +> "output": { +> "status": "200" +> } +> } +> ``` + +## Resume Akka Traffic +Removes rules in IP Tables to allow Akka traffic to/from a specifc node on a specified port. + +> ### Input: +> ```json +> { +> "input": { +> "node-info": [ +> { +> "node": "your.odl.node", +> "port": "2550" +> } +> ] +> } +> } +> ``` +> +> ### Output +> ```json +> { +> "output": { +> "status": "200" +> } +> } +> ``` + +## Failover +Only usable in a 6 ODL node configuration.
