Procedure Infrastructure Monitoring

D4ScienceAn e-Infrastructure operated by the D4Science.org initiative. Infrastructure Monitoring

The monitoring of the D4ScienceAn e-Infrastructure operated by the D4Science.org initiative. infrastructure is carried out by Infrastructure Managers, Site Managers, VRE Managers, VO Admins, and Data Managers. Such activity is done on a regular basis using the different tools provided to monitor the status of the Resources (check below).

In case a new problem is identified an incident should be reported immediately following the Incident Management procedure.

D4ScienceAn e-Infrastructure operated by the D4Science.org initiative. Resources

The monitoring of the D4ScienceAn e-Infrastructure operated by the D4Science.org initiative. Resources of the infrastructure is based on several systems:

• IS Monitoring: Based on information published in the gCube Information System. This information is accessible from:
  • Advanced Monitoring
• Messaging System: Based on the information published by probes local to each node. This information is used to send emails to Site Managers when problems are found.
• Nagios: Based on the information gathered by Nagios about the availability of each gHN. In case of problems Nagios notifies by mail the Infrastructure Managers. The D4ScienceAn e-Infrastructure operated by the D4Science.org initiative. Nagios server is available at Nagios Server

Hadoop Resources

The Hadoop clusters are monitored through the Hadoop internal monitoring and tracking systems. These tools provide monitoring for MapReduce jobs and for HDFS filesystems.

CNR	Job Tracker	DFS Health

Runtime Resources

The monitoring of the Runtime Resources of the infrastructure is based on 2 systems:

• IS Monitoring: Based on information published in the gCube Information System. This information is accessible from:
  • Advanced Monitoring
• Nagios: Based on the information gathered by Nagios about the availability of each Runtime Resource. For some of the Runtime Resources additional checks are going to be instrumented ( e.g. Mysql or PSQL DB DB sizes, or Index Usages) in Nagios.In case of problems Nagios notifies by mail the Infrastructure Managers. The iMarine Data e-InfrastructureAn operational combination of digital technologies (hardware and software), resources (data and services), communications (protocols, access rights and networks), and the people and organizational structures needed to support research efforts and collaboration in the large. Nagios server is available at Nagios Server
