Network Monitoring Tools – sflow


  • sflow is used to monitor fast networks (phaal
  • It provides more information regarding data flow statistics
  • It gives a comprehensive preview on how networks are used enabling efficiency in performance and billing the usage of the data together with the defense against threats to security
  • It is cost effective
  • The sflow continually monitors the network and is still robust
  • It shows historical and real time data to a greater detail

sflow Functions

  • Helps in monitoring every server and client
  • It helps to determine whether the network is heterogeneous or complex
  • Helps in monitoring the network traffic to determine whether there is efficiency in the network

Sflow importance

  • sflow is among the industry’s basis on which networks are monitored.
  • sflow further helps the company to determine the various bottlenecks associated with bandwidth
  • It further helps a company carry out an evaluation on the network by troubleshooting

sflow benefits

  • The cost of networks are controlled
  • sflow helps to maintain the traffic within the guidelines of SLA
  • Distributes costs to the specific departments in that it gives more data about specific users, company entities and applications usage
  • Help in the organization of upgrades that are cost effective which further helps in detecting bottlenecks and thus help in predicting resource needs

sflow Limitations

  • It does not give concise details of the number of packets in the networks
  • Since many streams are sent without encryption they can be a security threat
  • Routers and switches need to be compatible with sflow for a complete analysis of the network
  • While working with a big number of devices using sflow the bandwidth flow in regard to sflow processes is quite substantial
