Collector performance

2011-09-26 23:56:10

The collector is now fully tuned to the 100000 services and nodes objective. The dashboard has been reworked to handle millions of alerts. This view now reloads only when its database table has changed. Finally the xmlrpc inserts are now queued in a fast path and asynchronously dequeued, which allows the a single collector https front-end to accept about a thousand calls per minute.

NFS High Availability cookbook

2011-09-19 19:57:00

A new cookbook has been added to the documentation. It covers the setup of a highly available NFS OpenSVC service. This cookbook applies to Linux in-kernel NFSd implementation. The examples apply to Red Hat Enterprise Linux file layout, but other layouts should be similar enough for readers to be able to adapt.

Collector performance

100000 nodes, 100000 services, 100 compliance modules. These are the test data cursor size the OpenSVC collector is being tuned to work with. Most views where optimized for during the summer. Smaller deployments will benefit too.

Application inventory

2011-09-01 22:24:17

The OpenSVC nodeware now can push to the collector key/value pairs for the applications started by OpenSVC services. If a launcher implements the 'info' method, and this method outputs "key: value" lines, these pairs are pushed to a collector view suited for datamining. Application and licence inventory, version and build options comparison all become accessible with a few clicks.

OpenHA heartbeat branch

2011-09-01 22:20:34

OpenSVC now hosts a branch of the OpenHA heartbeat project. The main incentive is to enhance the disk heartbeat subsystem. We added a DirectIO heartbeat and fixed some bugs. The branch is tracked on http://git.opensvc.com and the changes are pushed upstream.
