A Tool for Understanding OpenStack Cloud Performance using Stacktach and the OpenStack Notification System
In one of our projects, FICORE the continuation of FIWARE, we need to offer an Openstack-based service. One aspect of service operations is to understand the performance of the system and one particular aspect of this is to understand how long basic operations take; it is interesting to see how this evolves over time as, […]
N_O_conf: nagios-based monitoring of Openstack made easy
“The autoscaling cloud monitoring system that requires no manual reconfiguration” “Nagios OS autoconfigurator” (N_O_conf) is a cloud monitoring system that automatically adapts its monitoring behavior to the current user-initiated VM infrastructure. N_O_conf works by installing a cloud environment change listener daemon which is repeatedly polling the OpenStack API for changes in the VM infrastructure. As […]
Full-stack Monitoring for OpenStack
Introduction The Ceilometer project is a core OpenStack service that provide collection of metering data on managed virtual resources (e.g. compute, storage, networking). Before it was only possible to collect data from OpenStack virtual resources which are running upon an OpenStack deployment. The work presented hereafter addresses this issue outlines a means to monitor both virtual […]
Ceilometer Performance issues
Update: This does not apply to Icehouse. This flag was to activate an experimental feature -this option no longer exists in Icehouse. (It is in Havana, however). There have been some criticisms of the implementation of Ceilometer (or Telemetry as of Icehouse) – however, it’s still the main show in town for understanding what’s going […]
Nagios / Ceilometer integration: new plugin available
The famous Nagios open source monitoring system has become a de facto standard in recent years. Unlike commercial monitoring solutions Nagios does not come as a one-size-fits-all monitoring system with thousands of monitoring agents and monitoring functions. Nagios is rather a small, lightweight monitoring system reduced to the bare essential of monitoring: an event management […]
When do you need to scale up?
A big issue in cloud computing is knowing when you should upstart more VMs or switch to a more powerful virtual machine in order to process user requests efficiently. Monitoring system utilization is very important for detecting if VM utilization is too high to guarantee stable and high performing IT services. But how can one […]
High Availability on OpenStack
ICCLab’s MobileCloud Networking solution is supposed to offer private cloud services to end users. MobileCloud is based on OpenStack. Since our OpenStack installation is supposed to be used mainly by end users, it is necessary to provide High Availability.
As mobile end users we all know that we want our IT services to be available everytime and everywhere – 24 hours per day, 7 days per week, 365 days per year. End users normally don’t reflect that this requirement is challenge for system architects, developers and engineers who offer the IT services. Cloud components must be kept under regular maintenance to remain stable and secure. While performing maintenance changes, engineers have to shut down components. At the same time the service should still remain available for the end user. Achieving High Availability in a cloud environment is a very complex and challenging task.
ICCLab Present on Ceilometer at 2nd Swiss OpenStack User Group Meeting
On the 19th February the 2nd Swiss OpenStack User Group Meeting took place. One of the presentations was held on Ceilometer by Toni and Lucas from the ICCLab. They talked about the history, the current and future features, the architecture and the requirements of ceilometer and explained how to use and extend it. You can […]
Monitoring and OpenStack
Many people think it maybe an unnecessary burden to set up a monitoring system for their infrastructure. However this, when it comes to an OpenStack installation should be considered indispensable and required. Knowing which resources are used by which VMs (and tenants) is crucial for cloud computing providers as well for their customers from billing and usage perspectives.
