In questo ultimo periodo abbiamo avuto spesso delle lamentele da parte di un nostro cliente sulle performance del loro gestionale in ASP.
Analizzando i grafici di NetEye con Cacti: sia l’Advanced ping sia l’in e out band del traffico si è potuto vedere chiaramente che in certi orari c’era un massiccio consumo della banda.
È stato così identificato che il problema delle prestazioni dello ERP, il quale comunica in protocollo http, era da ricollegarsi al consumo elevato di banda in questa fascia oraria.
Confrontando i dati con i feedbacks degli utenti finali abbiamo avuto la conferma che lo slow down del sistema era proprio nel periodo in cui nei grafici l’advanced ping mostrava round rip molto alti, packet loss e consumi elevati.
Ma come risalire alle origini e capire la ragione dell’utilizzo elevato della banda?
In quest’occasione abbiamo potuto apprezzare il grande valore aggiunto che ci ha dato le funzionalità di NTOP integrato in NetEye. Attraverso la raccolta dei flussi di rete tramite nprobe e l’analisi dei dati storicizzati archiviati in NetEye siamo riusciti velocemente a ricavare i protocolli e gli indirizzi IP coinvolti. Grazie ai filtri a livello di sotto reti (per esempio src net 10.67.10.0/26) si riesce a vedere tutta la comunicazione in origine.
Hi everybody, I’m Andrea and my contribution to this blog is to give hints of the monitoring issue from an IT manager point of view. I was born in Bolzano in 1965 and my professional path started 25 years ago operating on the technical field as programmer, system/database administrator, network engineer, consultancy and so on. I’ve been living in Milan for 10 years working for multinational IT companies and I decided to return to Bolzano after my marriage and the birth of my daughter.
I love sailing and diving in the summer, skiing in the winter and travelling off-road with my Landcruiser anytime
