TopBDII flooding unnecessary connections
It has been reported to EGI Operations that the TopBDII is trying many unnecessary connections to 2180/tcp because of how it's configured. This is basically due to the OSG flag still configured to "true" in /etc/glite/glite-info-update-endpoints.conf, resulting in a hourly cronjob to try establishing many useless connections.
It is enough to set OSG=false in order to prevent this useless traffic. Sites providing TopBDII are kindly asked to apply OSG=false to their configuration. An update to the glite-info-update-endpoints package will be released in UMD4 in the next days together with the regular UMD update.

Feedback from DMSU
Notifications from ARGO about the nagios probes failures
In the process of implementing the notification system in ARGO, it was introduced the following changes in GOC-DB:
- Notifications flag at the site level
- Notifications flag at the service endpoint level
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:
If there isn't any email contact defined at the service endpoint level, it will be used the site contact. Please review your contacts.
You can enable the notifications.
NOTE: It is not mandatory for the sites

Decommissioning EMI WMS
WMS servers can be decommissioned. Please follow the procedure PROC12. The plan is:
- Starting from January 2018, put the WMS servers in draining: this will block the submission of new jobs and will allow the jobs previously submitted to finish
- inform in advance your users that you are going to put in draining and then dismiss the WMS servers (as per PROC12)
- there might be several VOs enabled on your WMS servers: in case only few of them need to use the service for few weeks more, you might disable the other VOs
- On Dec 14th EGI Operations sent a new broadcast to the VOs reminding the users the forthcoming WMS decommission
- From March, the nagios probe eu.egi.sec.WMS will return a CRITICAL status for the servers still in production, and the ROD teams will open a ticket to the sites that haven't finished the decommission process yet
Tickets opened Oct 4th:
- BUDAPEST: https://ggus.eu/index.php?mode=ticket_info&ticket_id=137553 (SOLVED)

IPv6 readiness plans
- assessment ongoing https://wiki.egi.eu/w/index.php?title=IPV6_Assessment
- still missing NGIs/ROCs
- added column in FedCloud wiki to monitor IPv6 readiness of cloud sites https://wiki.egi.eu/wiki/Federated_Cloud_infrastructure_status#Status_of_the_Federated_Cloud
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.
- webdav endpoints registered in GOC-DB: https://goc.egi.eu/gocdbpi/public/?method=get_service&&service_type=webdav
- link to nagios results: https://argo-mon.egi.eu/nagios/cgi-bin/status.cgi?servicegroup=SERVICE_webdav&style=detail
- 5 CRITICAL out of 34 (OK status: 85.3%)
List of sites that not have completed the configuration yet:
- NGI_HR: egee.irb.hr https://ggus.eu/index.php?mode=ticket_info&ticket_id=134458 (webdav URL missing in GOC-DB...)
Storage accounting deployment
During the September 2017 meeting, OMB has approved the full-scale deployment of storage accounting. The APEL team 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.
Test portal: http://accounting-devel.egi.eu/storage.php
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.
