Details

Nagios is a host and service monitor designed to inform you of network problems before your clients, end-users or managers do. It has been designed to run under the Linux operating system, but works fine under most *NIX variants as well.

The monitoring daemon runs intermittent checks on hosts and services you specify using external"plugins" which return status information to Nagios. When problems are encountered, the daemon can send notifications out to administrative contacts in a variety of different ways (email, instant message, SMS, etc.). Current status information, historical logs, and reports can all be accessed via a Web browser.

Features

• Monitoring of network services (SMTP, POP3, HTTP, NNTP, PING, etc.)
• Monitoring of host resources (processor load, disk and memory usage, running processes, log files, etc.)
• Monitoring of environment / temperature
• Simple plugin design that allows users to easily develop their own host and service checks
• Ability to define network host hierarchy, allowing detection of and distinction between hosts that are down and those that are unreachable
• Contact notifications when service or host problems occur and get resolved (via email, pager, or other user-defined method)
• Optional escalation of host and service notifications to different contact groups
• Ability to define event handlers to be run during service or host events for proactive problem resolution
• Support for implementing redundant and distributed monitoring servers
• External command interface that allows on-the-fly modifications to be made to the monitoring and notification behavior through the use of event handlers, the Web interface, and third-party applications
• Retention of host and service status across program restarts
• Scheduled downtime for supressing host and service notifications during periods of planned outages
• Ability to acknowlege problems via the Web interface
• Web interface for viewing current network status, notification and problem history, log file, etc.
• Simple authorization scheme that allows you restrict what users can see and do from the Web interface

• realy good tool for an absolute acceptable price Thanks to the community
• Best network monitor program!
• I've been using this in our shop of 25 netware servers, 4 win32, and 5 linux machines and wouldn't be able to manage failures without this little guy.
• Very advanced tool. In our little shop we've already set up 99 service checks for our 10 servers, and this was done over a couple of days. We're still adding service checks, so we'll probably be well over 150 soon. Already it has payed of, our Groupwise server went down, and I got an SMS immediately.
