Service Availability Metrics (SAM) Plot Interface

Links to SAM Graph Generators

The CERN SAM query web interface changes quite frequently, and it is unreliable as a source of scraped graphs for our local monitoring.

We have implemented instead local graph generators for availability and reliability plots which are based on the published API. Using this API we formulate json-based queries. Then we use the PHPlot library to generate local copies of SAM graphs from the json-formatted data; for example:

TRIUMF-LCG2

This is the current list of plotting resources; it will evolve as we improve the interface. Please let me know what is missing or what needs fixing.
