OpenStack- Cinder Opspack Overview
OpenStack is an open source software platform for cloud computing and mostly deployed as an infrastructure-as-a-service (IaaS). The main initiative of OpenStack is to create and manage large groups of virtual private servers in a data center via web-based dashboards, command-line tools, or a RESTful API. OpenStack supports compatibility between cloud services and enable businesses to build Amazon-like cloud services in their own data centers. Freely available under the Apache 2.0 license, OpenStack is commonly labeled as the “Linux of the Cloud".
Cinder is a Block Storage service for OpenStack. It's designed to present storage resources to end users that can be consumed by the OpenStack Compute Project (Nova).
What You Can Monitor
Opsview Monitor's Cinder Opspack can help detect issues within your Cinder environment by providing performance counters for volumes and snapshots. There are specific service checks that monitor both the status and size of your critical snapshots or volumes, ensuring that they remain active and do not become too large. By having a quick view into these key statistics, you can utilize these service checks to receive alerts, display them in a customizable dashboard, or graph data size of a volume in our Graph Center.
