Notifications from ARGO about the nagios probes failures

In the process of implementing the notification system in ARGO, it has been recently introduced the following changes in GOC-DB:

In this way ARGO will retrieve from GOC-DB the information about the sites and services whom sending the email notification and the related recipients.

The logic of the notifications is the following:

Site Service Notify?
Y Y Y
Y N N
N Y N
N N N

If there isn't any email contact defined at the service endpoint level, it will be used the site contact. Please review your contacts. (the notifications are not implemented yet in ARGO)

NOTE: It is not mandatory for the sites

NGI ARGUS servers not properly configured

IMPORTANT: The ARGUS version that fixes the PAP permissions has been released in UMD 4.6: http://repository.egi.eu/2017/12/18/release-umd-4-6-0/ Please update to this version.

As reported by EGI-CSIRT during the February OMB, several NGI ARGUS servers are not properly configured and they are not passing the nagios tests (eu.egi.Argus-DNs probe):

How the probe works:

Requirements for passing the test:

Information about the nagios errors and possible solutions: https://wiki.egi.eu/wiki/EGI_CSIRT:Central_emergency_suspension#NGI_Argus_Monitoring

Information on global banning set-up: https://wiki.nikhef.nl/grid/Argus_Global_Banning_Setup_Overview#NGI_Argus

Decommissioning EMI WMS

WMS servers can be decommissioned. Please follow the procedure PROC12. The plan is:

WMS servers in downtime on GOC-DB

16 WMS still registered on GOC-DB as production and monitored (1 month ago they were 32)

Status on nagios

IPv6 readiness plans

webdav probes in OPERATORS profile

The webdav probes was included in the ARGO_MON_OPERATORS profile after the approval in the January OMB: in this way the failures will generate an alarm on the dashboard, and the ROD teams can open a ticket to the failing sites. If no particular issue occurs, and if at least 75% of webdav endpoint are passing the tests, the probes will be added in the ARGO_MON_CRITICAL profile, so the results of these probes will be taken into account for the A/R figures.

List of sites that not have completed the configuration yet:

List of sites that disabled webdav: UNIGE-DPNC, GR-01-AUTH, HG-03-AUTH, CETA-GRID, WUT

Storage accounting deployment

During the September meeting, OMB has approved the full-scale deployment of storage accounting. The APEL team has tested it with a group of early adopters sites, and the results prove that storage accounting is now production-ready.

Storage accounting is currently supported only for the DPM and dCache storage elements therefore only the resource centres deploying these kind of storage elements are requested to publish storage accounting data.

In order to properly install and configure the storage accounting scripts, please follow the instructions reported in the wiki: https://wiki.egi.eu/wiki/APEL/Storage

IMPORTANT: be sure to have installed the star-accounting.py script v1.0.4 (http://svnweb.cern.ch/world/wsvn/lcgdm/lcg-dm/trunk/scripts/StAR-accounting/star-accounting.py)

After setting up a daily cron job and running the accounting software, look for your data in the Accounting Portal: http://goc-accounting.grid-support.ac.uk/storagetest/storagesitesystems.html. If it does not appear within 24 hours, or there are other errors, please open a GGUS ticket to APEL who will help debug the process.

IMPORTANT: Do not encrypt the storage records with your host certificate, please comment out the “server_cert” variable in sender.cfg

List of sites already publishing and of tickets opened is reported here. Several sites are not publishing the storage accounting data yet. NGIs please follow-up with the sites the configuration of the script in order to speed-up the process.
