12. Nagios Use In the Library Nagios offers complete monitoring and alerting for servers, switches, applications, and services Nagios alerts IT staff to problem situations Nagios provides information on outage patterns both for in-house troubleshooting and discussions with service providers.

13. Nagios Use In the Library Nagios comes with several pre-built plugins you can use to monitor common services such as HTTP, FTP, DNS, etc. Makes configuring Nagios relatively easy for these services Nagios allows you to create custom plugins to meet your exact needs. For example, you can create the plugin to monitor to service a number of ways.

14. Nagios Use In the Library Nagios provides access control through the combination of settings in the cgi.cfg and htpasswd.users files. Library administration and staff, as well as patrons, may appreciate the ability to see the status of the various systems

15. Nagios Issues Monitoring uses bandwidth and adds to the load of machines being monitored IT departments should only monitor servers or devices it has permission to monitor Care should be taken to avoid disclosing sensitive information regarding the network or passwords, or allowing access to CGI programs that perform actions. User contributed plug-ins often require the installation of other software, most notably Perl modules. Issues with Configuration All remote host have to have a configuration file and every type of service to monitor has to have a configuration file. Then all these configuration file have to be incorporated together to build the monitor configuration. This can cause getting Nagios to perform the checks the way you want it to be confusing and difficult. Although Nagios is free, installing and configuring has a learning curve which takes time and computing resources
