16. A Hard Puppexit from 3 to 4

Jerome Belleman (CERN)

24/04/2017, 16:15

Basic IT Services

During the first quarter of 2017 CERN IT migrated from a Puppet 3-based service to a Puppet 4 one. We highlight the steps we took, the methods we used and the problems we discovered along the way.

39. salt stack - Using, Extending, and programming

Owen Synge

Basic IT Services

saltstack is a newer configuration management tool, first developed for remote execution. This talk will cover my experiences with salt in two organizations, with two different roles.

• Cleaning up an organizations use of salt.
• Making ceph execution modules in python.

27. Centralising Elasticsearch

Ulrich Schwickerath (CERN)

Basic IT Services

In January 2016 CERN launched a new project with the aim to provide a centralised Elasticsearch service. This presentation will summarise the status of the project,
challenges, experiences from the pre-production phase, and methods applied to configure access control.

10. The evolution of monitoring system: the INFN-CNAF case study

Mr Stefano Bovina (INFN)

27/04/2017, 14:55

Basic IT Services

Over the past two years, the operations at CNAF, the ICT center of the Italian Institute for Nuclear Physics, have undergone significant changes. The adoption of configuration management tools, such as Puppet, and the constant increase of dynamic and cloud infrastructures have led us to investigate a new monitoring approach. The present work deals with the centralization of the monitoring...

36. Unified Monitoring Architecture for CERN IT and Grid Services

Jaroslava Schovancova (CERN)

27/04/2017, 15:20

Basic IT Services

For over a decade, the CERN IT Data Centres have been using a centralized monitoring infrastructure collecting data from hardware, services and applications via in-house sensors, metrics and notifications. Meanwhile also the LHC experiments were relying on dedicated WLCG Dashboards visualizing and reporting the status and progress of the job execution, data transfers and sites availability...

19. Data Collection and Monitoring update

Cary Whitney (LBNL)

27/04/2017, 16:15

Basic IT Services

Touching on the fact that we have an ongoing data collection project and its progression to the next phase, monitoring. Talk about a couple of monitoring paths taken, ones that look promising also talk about the ones that failed.

Building upon last year, I'll discuss a bit about how to create a small data collection and monitoring setup. Instruction will be place on the HEPiX twiki.

6. Flexible, scalable and secure logging using syslog-ng

Mr Péter Czanik (Balabit)

27/04/2017, 16:40

Basic IT Services

Event logging is a central source of information for IT.
The syslog-ng application collects logs from many different
sources, performs real-time log analysis by processing and filtering them,
and finally it stores the logs or routes them for further analysis.

In an ideal world, all log messages come in a structured format, ready to
be used for log analysis, alerting or dashboards. But in a...

2. Typical syslog-ng use-cases at our Tier-1

Fabien Wernli (CCIN2P3)

27/04/2017, 17:05

Basic IT Services

We present the log infrastructure at CCIN2P3 and illustrate how syslog-ng plays a central part in it.
Following up on Balabit's talk on syslog-ng's features, we present several use-cases which are likely to be of interest to the HEPiX community.
For instance, we present real-life examples on how to parse and correlate operating system and batch scheduler events.
We present its integration...
