|Title||Modification of the set of AVAILABILITY tests|

|Policy Group Acronym||OMB|
|Policy Group Name||Operations Management Board|
|Contact Person||E. Imamagic|
|Procedure Statement||This document specifies the procedure for modifying the set of AVAILABILITY tests, i.e. of those tests whose results affect the computation of the monthly Availability and Reliability statistics.|
The purpose of this document is to clearly describe the procedure for modifying the set of AVAILABILITY tests, i.e. of those tests whose results affect the computation of the monthly Availability and Reliability (A/R) statistics.
This procedure applies to set of AVAILABILITY tests which are run under OPS VO and its range is global, applies for all Operations Centres in EGI project. These tests are used in the official EGI ACE profile used for generating monthly A/R reports.
This procedure does not apply to A/R statistics calculated for other VOs (e.g. user communities, national operations VOs).
This procedure requires usage of ACE system for generating monthly A/R statistics. The procedure does not cover GridView system which is currently used. The critical feature which ACE supports and GridView lacks is definition of multiple profiles for A/R statistics. Detailed information about ACE system can be found on the following link: https://tomtools.cern.ch/confluence/display/SAM/ACE.
In case when modification request includes addition of new tests, each test MUST first go through following procedures:
Two procedures above assure that the new tests are included in SAM release, deployed on all NGI SAM instances and accepted by operators.
- Everyone is allowed to submit the request for modifying the set of AVAILABILITY tests.
- The procedure requires generation of two A/R reports for comparison (find details below). Therefore only one request will be processed at a time. Order of processing requests will be defined by the SA1 activity leader.
|1||Requester||Opens a RT ticket in queue noc-managers.
Subject: Request for adding/removing XXX(,YYY,...) test(s) from the set of AVAILABILITY tests We would like to request adding/removing XXX(,YYY,...) test(s) from the set of AVAILABILITY tests Prerequisite data: * name of nagios probe: * name of service on which the test runs: * link to documentation page: * motivation (which part of the infrastructure will be improved with the new probe or description of users' problems which will be avoided in future - provide list of GGUS tickets is possible)
|2||SA1 activity leader||Schedules presentation of the new probe at the next possible OMB meeting.|
|3||Requester||Explains the reason for modifying set of AVAILABILITY tests|
|4 (*)||SA1 activity leader||Opens a ticket in JIRA requestting creation of new ACE profile with modified set of AVAILABILITY tests.|
|5 (*)||ACE team||ACE team creates the new ACE profile.|
|6||SA1.8 task staff||For the following one month two A/R reports are generated. SA1.8 task staff compares the figures and presents them at the next OMB meeting.|
|7||OMB||If the A/R statistics generated with the new A/R profile are satisfactory OMB approves the modification|
|8 (*)||SA1 activity leader||Opens a ticket in JIRA requestting that the new A/R profile becomes the official for EGI. The previous profile is to be removed.|
|9||SA1 activity leader||Broadcasts the modification to all relevant parties (i.e. noc-managers, inspire-sa1). Closes the initial RT ticket.|
(*) - These steps depend on the procedure for creating new profiles which will be defined by the ACE team once the ACE is in production. Steps defined here have been provided by the ACE team. This procedure will be updated if any change occurs.
