Just like a car or any appliance, it may need maintenance or parts replaced to keep it in top working order. Network and server monitoring allows the Network Administrator to see how hardware and software are performing. We can look for certain signs or warnings that the system is not working efficiently and take action to fix things to prevent system degradation or failure. What is Nagios? — Monitoring of network services such as SMTP, POP2, HTTP, NNTP, ICMP, SNMP, FTP, SSH. A Real Example Of Nagios Monitoring — There are two major problems the monitoring solves: alerting and trending. Alerting is to notify the person in charge about a major event like service failing to work. Trending is to track the change of something over time – disk or memory usage, replication lag etc. graphios — A program to send nagios perf data to graphite (carbon) / statsd / librato / influxdb Sensu — Sensu’s platform is the solution to the monitoring problems you’re facing today, and the right foundation for your organization tomorrow.
