ServiceGuard and OpenSVC

2012-05-10 22:41:30

A new class of service has been added to OpenSVC. This class allows wrapping a ServiceGuard package into an OpenSVC service. No action is actually possible on such a service, but status, service inventory, disks inventory are consolidated into the collector views along with pure OpenSVC services. Moreover, compliance modulesets and rulesets can be attached to ServiceGuard packages through their wrappers. Configuration of such wrapper services is trivial, as all resources and most service information are gathered directly from ServiceGuard.

Storage Array parsers

2012-05-10 22:36:21

The storage management views of the collector are fed by the OpenSVC agents from nodes side, and by ad-hoc array parsers from the storage side. This news bill announce the availability of the following parsers: NEC ISM, EMC DMX and DMX-3, HP StorageWorks EVA, IBM SVC and DataCore appliances. Parsers are quite easy to develop, so more will come when the need arises.

OpenSVC Storage Management

2012-05-10 22:22:02

Starting with opensvc agent version 1.4, the collector gets fed with storage information from the nodes : hba port names, visible target port names and disk regions in relation to their consumer (node or service). The collector has a new view to mine this information, the disks view, filterable by array information, service name, nodename and application code. This view aggregates the filtered data into per-service, per-application code and per-array donut charts. The collector has also gained a quota view, to define per application code and per array disk group allocation quota. A new LUN provisioning tool allows delegation of LUN creation to end-users, enforcing the application quota and the provisioner privileges.

New documentation

2012-04-16 07:47:33

The documentation has moved to its own address: http://docs.opensvc.com, accessible through the 'Documentation' link above. The new documentation is built with sphinx, which brings many benefits : the search tool and the source tracker friendly format being the most interesting to OpenSVC. The docs.opensvc.com is now open for contribution on http://git.opensvc.com too. The initial content is heavily based on the former documentation material, with addition of nodemgr and nodemgr manpages.

DataCore drivers

2011-12-19 23:20:32

Two new drivers are available in the OpenSVC nodeware.

• The DataCore snapshot driver, dedicated to service data instant copy for use by other services
• The DataCore checkpointing replication driver, dedicated to off-site replication maintenance and DRP activation actions

Collector management CLI

2011-10-23 22:45:52

The collector data can now be accessed from the svcmgr and nodemgr commands. The list of supported commands is:

• status
• checks
• events
• alerts
• list actions
• show actions
• ack action
• list unavailability
• ack unavailability

On 21th October, in Paris, OpenSVC will be presented at the Asyd conference. We'll be happy to meet interested people and answer questions. Subscription form and sessions schedule at http://sysadmin.asyd.net/.

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.
