Today, just as in the past, the “data” is invaluable and what we will try to do here is use simple data we can easily collect (data which individually might have no value) and apply Machine Learning techniques in order to identify anomalies, and then…

Hyper-V monitoring: Here’s some tips!

Network traffic monitoring is traditionally based on SNMP queries. This protocol generates statistics on the transmission of data across one or more network interfaces. While network device queries still run through SNMP, using Microsoft Hyper-V monitoring requires the adoption of other approaches. One of the reasons is the network connection configuration itself: for example, many…

Analisi trend carico server

Ola da Barcellona, in questi giorni in Würth Spagna ho sviluppato un report che visualizza le medie di carico di CPU, I/O, memoria. Questa idea è venuta ai sistemisti spagnoli. Con questo report si riesce a capire qual’ è il carico medio di una macchina e se varia nel tempo. Gli intervalli temporali visualizzabili sono:…

Advanced PING graphs

Cacti allows with its graphing engine the representation of sophisticated graphs. One of the principle values to graph is the ping response time average together with the possible packet loss. Cacti enables you to pack both information in one single graph, while still remaining well structured and clearly readable.
