Introduction
Three set of tests are used in EGI monitoring:
- SAM tests: tests executed on NGI/ROC SAM instances
- Operations tests: tests which raise alarms in the Operations Portal
- Availability&reliability tests: tests which are used for availability calculation by the GridView
Within SAM/Nagios world we use the following naming:
- Test - procedure which checks specific functionality of a given service, i.e. single measurement (e.g. org.bdii.Freshness, hr.srce.RGMA-CertLifetime)
- Probe - code which implements single or multiple metrics.
These sets are different as they are used for different purposes. Below are description of tests and procedures for adding new tests.
SAM tests
Tests on NGI/ROC SAM instances are the one which frameworks includes in the SAM configuration. In addition SAM admins can add their own probes to these instances.
SAM teams proposes addition of new probes. The addition of probes is part of SAM release and thus part of the staged rollout. It was agreed that prior to release new list of probes will be briefly presented at the OMB meeting. Probes which perform internal components of SAM are not presented at OMB.
Operations tests
Tests on Operations Portal are the ones used for raising alarms for ROD and COD teams. Operations portal does not execute these tests, but receives alarms from NGI/ROC SAM instances. Operations Portal contains list of the probes used for alarms and others are filtered.
The procedure for adding a new probe can be found here.
The list of tests can be found here.
Availability&reliability tests
Set of tests used for calculating availability and reliability of sites and services. The A/R calculation is related to the OLA. As in case of Operations Portal, availability calculation component receives results from NGI/ROC SAM instances.
TSA1.8 proposes a change in avail calculation (which probe results count in it) and the OMB approves.
The list of tests can be found here.
