  1. Operational Tools Milestones James Casey SA1 Management Meeting Catania

  2. Introduction Architecture and design phase now finished All tools have provided plans with functionality and milestones for delivery • Some deployment milestones too Aim is for a set of milestone deliverables which given a certain complete functionality • 3 month intervals, starting April 2009 If timescales slip, we can stop at any of the milestones and have a complete functional solution • Sacrificing functionality or distribution

  3. Milestones and timeline

  4. M1 Features - April 2009 Regional Dashboard • ‘Regionalized’ dashboards at IN2P3 using current SAM tests for alarms GOCDB • Programmatic Interface (XML over HTTP) available • GOCDB 4 schema deployed with current data inserted for validation Configuration repositories • Aggregate Topology Provider (ATP) • What resources should I test ? • Metric Description Database • What tests should I use ? Gstat • First prototype of new monitoring (based on Nagios) done

  5. M1 Features – April 09 ROC level nagios based monitoring available • Configured from Metric Description Database and ATP • ‘SAM Portal’ level of visualization complete Full Nagios testing of all resources in grid running • At CERN – Central system, simulating 11 ROCs • Used to validate equivalence to SAM • Availability calculation using current algorithm but with new metrics QR Reporting Portal (MSA1.3) • Initial version with metrics for job usage implemented Accounting • Central infrastructure for ActiveMQ based accounting deployed

  6. M1 Deployment location of tools

  7. M1 impact on ROCs Not much ! • Something to look at and play with • No impact on operations Can start integrating GOCDB PI into tools which currently use direct DB connection to GOCDB

  8. M2 Features – July 09 Regional Dashboard • ‘Regionalized’ dashboards interfaced with regional Nagios • Raising alarms based on Nagios Configuration repositories • Metric Description Database • Availability calculation definition implemented GOCDB • Write functions for Programmatic Interface (XML over HTTP) available • XML over HTTP, Web Service and API available • Prototype interface to new GOCDB4 available • ‘region1’ use case deployed. Interfaces to ‘region3’ usecase defined

  9. GOCDB Regional models A reminder of some terms : • Region 1 • Use a distributed GOCDB instance • Customise it to their needs with minimal effort • Region 2 • Keep on using central GOCDB • Region 3 • Use their own model and implementation • Publish required data to a central system

  10. GOCDB details and components Region 3 Region 3 local portal Publisher Region 3 homemade local DB RAL 3rd party tools WS interface Central portal End users Query interface Region 1 Region 1 local portal Data processor data metadata Data collector Region 3 Query interface R3 GOCDB internal queries Region 2 R2 • Region 1 R1 Custom tables Region 1 R1

  11. M2 Features – July 09 ROC level Nagios based monitoring available • Now publishes to new central metric storeSubmission framework fully uses ATP • Central metric store result visualization (SAM Portal/gridview) QR Reporting Portal (MSA1.3) • Added reports for operations and user support use cases • Some still missing (operations.{1,2}, size.2) Accounting • Tested ActiveMQ transport with some selected sites • Patch submitted for gLite certification GGUS • MSG interface for ticket submission/update available SLA Calculation • Multiple simultaneous availability calculations for a VO

  12. M2 Component Deployment

  13. Data flow in M2

  14. M2 Impact on ROC Things are ready to be deployed • GOCDB • At east one ROC will have a regional GOCDB instance communicating with the central instance as a prototype • Regional Nagios for monitoring which can interact with operations dashboard • Accounting now will work with MSG • You can start the migration away from R-GMA This is point at which we could turn off SAM OPS tests • Relying now on Nagios testing, either centrally from CERN, or from the ROC • Smooth migration of testing from central to regional as ROCs come on board

  15. M3 Features – October 09 GOCDB • GOCDB4 in production • At least 2 regional instance working in parallel Gstat • First version of Gstat 2 available QR Reporting Portal (MSA1.3) • Remaining metrics added Accounting • APEL consumer/publisher available for use in regional model Aggregate topology Provider • Aggregate topology provider packaged for easy deployment in regions • For use with other regional tools (e.g. accounting, …)

  16. M3 Component deployment

  17. M3 Impact on ROC More regionalization available • Accounting • Aggregate topology provider • For regional tools which need integrated topology views • GOCDB – more regions could have moved • To either region 1 or region 3 model We can do QR metric report generation automatically from a portal

  18. M4 – December 09 Regional Dashboard • First prototype of pure regional dashboard Availability Calculation • Regional version of availability calculation available Metric Store • Regional version of metric store available to function along with regional availability calculator Accounting • Testing publication via MSG with regions who don’t use APEL Gstat • Gstat 2 in production • Possibility to deploy regional instances

  19. M4 Component deployment

  20. M4 Impact on ROC Where possible, components now available for integration as pure regional tools • Nagios for testing • Dashboard for operational ticketing • Metric store + Availability Calculator • Accounting In my personal opinion, very optimistic • Perhaps take as a “target” instead of a “milestone”

  21. Summary Progressive Milestones • Incremental changes in both functionality and regionalization 2 ‘big’ milestones for ROCs • July • Regional monitoring deployment • December • Regional version of dashboard • Regional version of availability calculation Risks • Regionalisation comes too late in the project • When people are winding down We aim to have a stable ‘escape point’ at each milestone • And can run with the system delivered at any point
