또다른, Top5 free 네트워크/싯트메 모니터링 툴 리스트 입니다.

물른 Nagios는 빠지지 않았고, 그외 익숙한 Ganglia가 눈에 띕니다.

그외 Zabbix (아래 또다른 모니터링 툴 리스트에서 언급), Spiceworks, Observium이 있네요.

저자는,

* Nagios는 가장 유명한 오픈 소스 모니터링 툴이며, 손으로 설정하는 것이 단점이지만, 가장 flexible 하며 alert 기능이 뛰어나다고 하며,

* Gaglia는 'scalable distributed monitoring system'으로 grid 및 cluster등의 모니터링 툴로 적합하며,

* Observium은 쉬운 UI 와 그래프 기능,

* Spiceworks는 시스템 맵기능을

* Zabbix는 그래프 기능과 리포팅 기능을

장점으로 언급하였습니다.

5개 중 3개가 PHP를 사용한다고 하니 PHP를 공부해 두는 것도 좋을 것 같습니다.

RRDtool - Wikipedia, the free encyclopedia

RRDtool (acronym for round-robin database tool) aims to handle time-series data like network bandwidth, temperatures, CPU load, etc. The data are stored in a round-robin database (circular buffer), thus the system storage footprint remains constant over time.

It also includes tools to extract RRD data in a graphical format, for which it was originally intended.

Bindings exist for Perl, Python, Ruby, Tcl, PHP and Lua. One independent full Java implementation exists: rrd4j.
