Description
EGEE JRA4 Network Performance Monitoring (NPM) is now working on a solution for providing NPM data to resource brokering middleware (RBMW), specifically the WMS and DM services.
Proposed topics for discussion:
- What kind of data would the RBMW like to access?
- metrics: confirmation of those already discussed mid-September
- times: past 24h of data? current data? predicted data?
- resolution: how often must unique measurements be available? every 5 mins? does this vary per metric?
- statistics: raw, min, max, mean? if stat, what interval?
- methodologies: parameters / tools desired
- including parameters per metric, acceptable load induced by measurements (if known)
- paths: between every CE/SE pair? every SE/SE pair? a manually configured set of nodes? will they be specified using the SE/CE id or by hostname (if they are different) or hostname of network monitoring point?
- How would the RBMW like to get access to the data?
- interface requirements: web service? ISM? R-GMA? SQL?
- timing requirements: how quickly must a response be provided for a request - can this be met with the chosen interface?
- expected load: requests per second, what combination of parameters each time?
- security: what kind of authentication can be provided (e.g. user's proxy) - perhaps only relevant for a web service interface
