Overview
On Februrary 14, 2012 Fermi nagios notification was migrated over to the SCS nagios system. Access privileges are required to use the commands in this document.
This documentation is intended to apprise someone, new to Nagios, about how to work within SCS Nagios. This documentation is intended to be used only as a starting guide; therefore, this documentation is not extensive and focuses on only the features of Nagios available to Nagios administrators for Fermi. This documentation will outline the general procedure for completing a Nagios related task, such as
- Schedule Downtime For Host or Service
- Where exactly the Nagios software resides
- Procedure to modify the Nagios configuration for a host or service
- View Nagios configuration in SVN
Nagios has extensive documentation available online (we are using Nagios 3.2.3) Nagios Core Version 3.x Documentation and Nagios Documentation (Library, Guides and Links)
What is Nagios?
Nagios is a network, and system, monitoring application. Essentially, Nagios watches specified hosts, and services, then alerts you when something goes wrong. Slac nagios is currently using Nagios core 3.2.3
Motivation
The Fermi Gamma-ray Telescope mission relies heavily on computers and network services for tasks, such as Science Analysis Software development, ground processing and data handling, data storage, etc.. The Fermi team heavily depends on machines, and services, at SLAC, Goddard Space Flight Center, and other participating institutions. Therefore, team-members need to immediately know whenever equipment, services, or hosts, have any problems. Nagios 3.x is the open source host, and service, monitoring software that we are using to monitor hosts and services, and alert team-members about specified host and service events.
