Mandate
- assess the support status of various Nagios probes available
- recommend removal or replacement of unsupported probes from the SAM Nagios framework
- 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
Tasks
Documentation
Generic improvements
- Eliminate Broken Links
- collect all documentation links in a central place
Developers Documentation
- (add link)
- colelct requierments and suggestions from Developers
Probes
- Identified Isuses:
- NGI SAM Nagioses have documentation URL hardcoded in metric configuration
- changing the URLs requires SAM update
- Solution: - Plan the Change
- SAM CE Nagios framework is unsupported
- used for WN* tests
- Solution: - replace them
- SRM tests (add reference) cause false alarms on new DPM versions (add link to GGUS tkt)
- Solution: - ??
- org.gstat.SanityCheck - not maintained anymore
- checks small subset of BDII GLUE 1.2 data
- (add reference to profiles were it is enabled)
- Solution: replace with org.bdii.GLUE2-Validate - through validation of GLUE 2 data
- LFC decommissioning - with implications in tests depending on it
- org.sam.WN-Rep* (CREAM-CE)
- org.sam.WN-Rep* (CREAM-CE)
- Solutions:
- remove all LFC-dependent tests, or find replacement
- deploy dedicated LFC and reconfigure all NGI SAM Nagioses
- SAM requires unsupported software
- UMD 2 middleware:
- Solution: migration to UMD-3 planned in September - FOllow-Up
- 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
- NGI SAM Nagioses have documentation URL hardcoded in metric configuration
