Nagios is a popular open source computer system and network monitoring application software. You can easily monitor all your hosts, network equipment and services. It can send alert when things go wrong and again when they get better.
The convenience and reliability that monitoring programs offer system administrators is astounding. Whether at home, commuting, or on vacation, admins can continuously monitor their networks, learning of issues long before they become catastrophes.
Nagios, the most popular open source solution for system and network monitoring, is extremely robust, but it’s also intensely complex. This eagerly anticipated revision of the highly acclaimed Nagios: System and Network Monitoring, has been updated to address Nagios 3.0 and will help readers take full advantage of the many powerful features of the new version. Ethan Galstad, the main developer of Nagios, called the first edition of Nagios “incredibly detailed.” He went on to say, “I don’t think I could have gone into that much detail if I wrote a book myself.”
Nagios, which runs on Linux and most *nix variants, can be configured to continuously monitor network services such as SMTP, POP3, HTTP, NNTP, SSH, and FTP. It can also supervise host resources (processor load, disk and memory usage, running processes, log files, and so on) and environmental factors, such as temperature and humidity. Readers of Nagios learn how to:
- Install and configure the Nagios core, all standard plugins, and selected third-party plugins
- Configure the notification system
- Program event handlers to take automatic action when trouble occurs
- Write Perl plugins to customize Nagios for unique system needs
- Quickly understand Nagios data using graphing and visualization tools
- Monitor Windows servers, SAP systems, and databases
This dense, all-inclusive guide to Nagios also contains a chapter that highlights the differences between Nagios versions 2 and 3 and gives practical migration and compatibility tips. Nagios, 2nd Edition is a key resource for any system and network administrator and will ease the pain of network monitoring migraines in no time.
Wolfgang Barth has written several books for professional network administrators, including The Firewall Book (Suse Press), Network Analysis (Suse Press), and Backup Solutions with Linux (Open Source Press). He is a professional system administrator with considerable experience using Nagios.
