Dear All,
as was previously announced, WLCG Experiments Test
Framework (ETF), which replaces the existing SAM/Nagios
infrastructure will enter production on 25th of April.
ETF is a framework to perform functional testing of
sites and services and it’s the main source of the
metrics for the the WLCG monthly availability and
reliability reports. It’s a re-designed and simplified
version of the previous framework, which is backward
compatible and will run the exact same plugins/metrics
as the previous one. A summary of the changes that ETF
introduces were presented at the WLCG operations
coordination on 18th of February and can be found at
https://indico.cern.ch/event/466818/.
The service change will be transparent in the SAM3
dashboards and APIs, which means that starting from 25th
of April the source of the measurements for the existing
profiles will be switched from the current SAM/Nagios
instances to the ETF. More details on the framework,
deployment and plugins can be found in the ETF
documentation at
http://etf.cern.ch/docs.
For any requests or comments, please open a GGUS ticket
to the WLCG Grid Monitoring support unit.
Best regards,
Marian Babik
