General information

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.

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:

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.

You can enable the notifications.

NOTE: It is not mandatory for the sites

Monthly Availability/Reliability

suspended sites:

Decommissioning EMI WMS

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

WMS servers in downtime on GOC-DB

7 WMS still registered on GOC-DB as production and monitored

Status on nagios

Tickets opened Oct 4th:

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 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.
