Storage dashboard

Status reportA.Baranovski

Summary from prev. meeting

• Information exchange board with functions that facilitate status “overview”

• Reuse LCG grid view tools• Understand if existing s/w extensible for

feature additions / changes• Display of the storage topology would be

desired• Ease of “scoping” - i.e. display only

relevant objects.

Integration with LCG s/w

• gridview project developers:– “I do not think it will be of much use … the

gridview displays is just a tip of the iceberg.”

• Lets scope down and deploy LCG SAM (basic display, no advance reporting tools)– Depends on Oracle 10g , LCG testing

framework • No effort to handle all that within reasonable time. • Not clear if result would actually be of any use

Status

• gridview is the comprehensive solution that by itself requires support effort (apart from integration development)– … in the process of handing it over to the

operations group here, so for that we are formalizing release procedures, writing admin and troubleshooting manuals and things like that …

Conclusion

• Timeframe to mature gridview s/w enough to make it reusable does not fit into the effort for building storage dashboard at Fnal.– Paradoxically it was simpler to prototype

generic resource display than to pursue existing framework

Resource dashboard

• 2D map of objects each aggregating some sort of pre-defined state. – Rendered on a single HTML page.

• Benefits from emerging WEB technologies not available at the time existing reporting tools had been developed.– Freedom in implementing features to make the tool

visually appealing and intuitive at little cost.

• Focused on context independent data format– Render storage, ce, network elements and their

properties

Resource dashboard basic design goals

• Look simple

• Support language and features which allow user to make “his” own kind of display

• Multiple data feeds

Where to go

• Focus on info exchange / GOC integration• RSS (Really Simple Syndication)

– Storage “news” concept. Keep yourself updated about status changes ( via google reader for example)

• Attribute time graphs as requested by user (space, status, bandwidth, etc)

• Editable content• Multiple data feeds ( currently Glue)• Complicated topology displays
