Mandate
- assess the support status of various Nagios probes available
- recommend removal or replacement of unsupported probes from the SAM Nagios framework
- request improvement/correction of supported ones
- ease their maintenance and support by:
- reducing the number of probes
- reducing the dependencies between services (a reported service error should not be caused by the problems of another service in the same site)
- improve documentation:
- availability of references to the individual nagios probes/tests descriptions in a central place
- update known documentations web pages with proper references (avoid broken links)
- improve developers guides
- require change to SAM to remove harcoded documentation URLs in metrics configuration
Reference:OMB, June 26, 2014 - Re-factoring SAM probes
Tools
Tasks
Documentation
Generic improvements
- eliminate Broken Links
- collect all documentation links in a central place
- create a unique page collecting descriptions of all available tests/probes
Developers Documentation
- collect requierments and suggestions from Probes Developers
Probes
Identified Issues
- NGI SAM Nagioses have documentation URL hardcoded in metric configuration - GGUS #108242
- changing the URLs requires SAM update
- Solution:
- Plan the Change
- org.gstat.SanityCheck - not maintained anymore - GGUS #108243
- checks small subset of BDII GLUE 1.3 data
- (add reference to profiles were it is enabled)
- Solution:
- replace with org.bdii.GLUE2-Validate - through validation of GLUE 2 data
- SAM requires unsupported software
- UMD 2 middleware:
- Solution: migration to UMD-3 planned in September - - SAM/ARGO task #6
- CentOS/SL5
- Solution: - migration to CentOS/SL6 planned within EGI InSPIRE JRA2 activity
- UMD 2 middleware:
- org.sam.SRM-GetTURLs fails if webdav is published
- the probe takes from the BDII the list of protocols published in the GlueSEAccessProtocol object and tries to access them using SRM. This fails for webdav.
- Solution:
- CERN DPM PT is developping a webdav SAM probe - GGUS #108571
- improve org.sam.SRM-GetTURLs, under dCache PT maintenance, to not ask/test SRM for a webdav TURL
- MPI Nagios probe issues for GE batch system - GGUS #108443
- GGUS #101406 - WARNING: Publishes GlueCEPolicyMaxCPUTime (30) / GlueCEPolicyMaxWallClockTime (30) < 4
- Solution
- rewriting the test to take into acount that GE provider now also provides correct CPU limit in the BDII per core and include it in the next SAM update
- remove/replace FTS(2) probes - GGUS #108458
- FTS2 has been decommissioned since the 1st of August;
- the Nagios FTS probes are not suited for FTS3 and so they can be removed.
- Solution:
- follow-up with TP (OliverK & MaiteBL) the development of FTS3 probes and their integration in in SAM
- SAM CE Nagios framework is unsupported
- used for WN* tests
- Solution: - replace them
- LFC decommissioning - with implications in tests depending on it
- org.sam.WN-Rep* (CREAM-CE)
- org.sam.WN-Rep* (CREAM-CE)
- Possible Solutions (under evaluation:
- deploy dedicated LFC and reconfigure all NGI SAM Nagioses
- SRM tests (add reference) cause false alarms on new DPM versions (tests for SRM API all the interfaces published in the Top-BDII) (add link to GGUS tkt)
- Solution: - ??
