MindSphere Managed Backing Services¶
This section gives an overview of the included Backing Services. Each instance of a Backing Service runs on a dedicated virtual machine. These virtual machines and services are operated by MindSphere.
Available Backing Services¶
The following Backing Services are currently included:
| Backing Service | Description | Plan |
|---|---|---|
| MongoDB | MongoDB is a document data base that stores data in flexible, JSON-like documents, meaning fields can vary from document to document and data structure can be changed over time | mongodb-xs and mongodb-m |
| PostgreSQL | PostgreSQL is a powerful, open source object-relational database system. | postgresql-xs and postgresql-m |
| Redis | Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker. | redis-xs and redis-m |
| RabbitMQ | RabbitMQ is the most widely deployed open source message broker. | rabbitmq-xs and rabbitmq-m |
| Elasticsearch | Elasticsearch is a distributed, RESTful search and analytics engine capable of solving a growing number of use cases. As the heart of the Elastic Stack, it centrally stores your data so you can discover the expected and uncover the unexpected. | elasticsearch-xs and elasticsearch-m |
| LogMe | LogMe allows to provision Elasticsearch, Logstash and Kibana, i.e. the ELK-stack. Simply bind your Cloud Foundry app to LogMe and it will automatically start collecting metrics and syslogs from your apps and services. | logme-xs and logme-m |
Service Plans¶
All service plans (*-xs and *-m) are enabled for every Org. Those plans are all marked as paid plans as you can buy additional instances of those. Depending on your offering a certain amount of concurrent instances is included. The following table lists those for the MindAccess Developer Plan:
| Offering | Concurrent instances included |
|---|---|
| Developer Plan S | 2 XS instances |
| Developer Plan M | 4 XS instances |
| Developer Plan L | 6 XS instances |
You can buy additional service instances in different sizes via the MindSphere Store. Therefore, the Cloud Foundry quota of your Org does not reflect allowed number of concurrent service instances.
Update to a larger Service Plan¶
Upgrade the service plan using the following command:
1 | cf update-service <serviceName> -p <largerPlanName> |
Disk Alerts¶
Every service instance is monitored by a Parachute component to evaluate the ephemeral and persistent disk usage. If a disk usage reaches the configured threshold Parachute stops all of this instance's processes and writes a message into the log directory:
Limit reached for: <persistent/ephemeral> disk
Restart Stopped Instances¶
The disk usage threshold for service instances is set to 80% by default. When restarting a stopped service instance, the threshold can be configured using the max_disk_threshold parameter. It accepts integer values between 0 and 100. The following sample shows how to restart a service instance with a threshold of 90%:
1 | cf update-service <serviceName> -c '{"max_disk_threshold": "90"}' |
Restarting the service instance takes a few minutes.
Attention
This is only a temporary solution. The service instance is stopped when the threshold is reached again. For a long-term solution, the service instance must be updated to a larger plan size if available.
