James Casey, David Collados

2. SAM and Nagios in WLCG At Current Moment
Calculation of site availability for sites done in SAM
March Availability computations
Parallel computations based on SAM & Nagios probes
Equivalent metrics for CE, SRMv2 & sBDII
Using same algorithm (gridview)

3. March - Nagios Based Report
March Availability reports for EGEE sites
Official SAM report:
Unofficial Nagios report:
315 EGEE sites in the report
Sites whose availability changed > 10% 40 = 12.7%
Sites whose availability increased > 10% 19 = 6.0%
Sites whose availability decreased > 10% 21 = 6.7%

4. March - Nagios Based Report
Sites whose availability decreased > 10% 21 = 6.7%
12 failed due to messaging brokers discovery, now OK
5 due to timeouts in job submit or missing libraries on WNs, now 4 OK, 1 fails
4 failing sBDII tests, now 2 OK, 2 fail
Differences understood and corrected in Nagios
Sites can/should check their current Nagios status
In the GridView Nagios portal:
Or in their corresponding ROC Nagios or MyEGEE instances:
And report any issue through the Nagios Support Unit in GGUS

5. April - Availability
Official availability reports for April will not change
Still calculated based on SAM probe results
We will also generate availability reports based on Nagios results
Continue the validation of Nagios availability by sites and project
Sites should check their current Nagios status and report any issue
