emi-nagios
metapackage there were dependency issues in case of EMI-1, the packages for EMI-2 installs properly.
EMI probes integration status (as for end of March 2012):
So far version of SAM-NAGIOS is based on gLite 3.2 UI, with partially integrated ARC and UNICORE probes for which special configuration is needed (see SAM-NAGIOS installation documentation for details).
Details of integration of the EMI probes with the SAM-NAGIOS framework are still under discussion. The major point is that until now environment for probe execution was done with YAIM configuration of glite-UI (an integral component of SAM-NAGIOS - so far...). In the new SAM-NAGIOS the gLite-UI YAIM configuration will be replaced with proper environment for each probe, which should be installed with all its dependencies and configured properly for independent execution. All this should be provided by EMI PTs releasing the probe. Only NAGIOS configuration part (NCG?) would be developed by SAM-Team (EGI).
Current implementation on the EMI Testbed:
NAGIOS and SAM-NAGIOS has been adopted as monitoring tools for Testbed resources. Minimal level of monitoring of a resource is HW/network availability (low-level monitoring). Service level monitoring is implemented for all services having probes integrated into SAM-NAGIOS.
In some cases, if partial integration of the EMI-probes in SAM-NAGIOS is done, service-level monitoring is used. Other service-level checks will be used for service-level Testbed monitoring when they will be integrated into SAM-NAGIOS framework.
Details about (SAM)-NAGIOS instances deployed at partner sites can be found on the Testbed inventory page.
CODE | KPI | Description | Method to Measure | Estimated Targets |
---|---|---|---|---|
KSA2.1 | SA2 Services Reliability | Percentage of uptime dependent only on the SA2 services themselves | Participating sites monitoring tools | 99.90% |
KSA2.2 | SA2 Services Availability | Total % uptime including the underlying suppliers | Participating sites monitoring tools | 97.00% |
KPI | Calculation Method |
---|---|
AVAILABILITY | Nagios reports per month, per server. Host time-up is considered in the calculation, since service probes are not available for all services. |
RELIABILITY | Reliability = Availability / (Availability + Unscheduled Downtimes). Example.1: Reliability is 100% only if NO Unscheduled Downtimes occurred in the period. Here just the final average value for the month (over servers) is provided. Example.2: Two out of ten hosts with availability of 97% and the rest of time in unscheduled downtime for 3% of the period, then reliability is: Reliability (for the 2 servers) = (97) / (97+3) = 97% ; Reliabilty (for other servers) = 100% (i.e. no unscheduled downtimes); Reliability (avg in the month) = (2*97 + 8*100)/10 = 99.4 %. Note that: since SA2.6 and EMI have no automatic downtime broadcast mechanism for testbed resources to set a scheduled downtime, all downtime announced at least 2 days in advance on the NEWS/WARNING section of this testbed twiki will be considered as SCHEDULED and therefore not affecting Reliability. |

In the near future, the VO will be deployed with EMI releases, and above info and files integrated in yaim profiles/examples and the certificate deployed through an rpm file
For ARC users: the VO configuration is described on NORDGUGRID VOMS usage notes page. For vomses file use the input as above.
For Unicore users: UNICORE does not support VOMS, so no configuration can be provided. UVOS, UNICORE VO solution, is to be phased out during the course of EMI, so we didn't deploy it in the testbed. It is planned to support the SAML based VOMS later on, but that is not available yet. If you require access to the testbed, you'll have to open a GGUS tkt send me your certificate and I will register it.
