The importance of good network flow supervision
Whatever the size and topology (single site, multi-site) of your information system, network links are always a critical component, and their monitoring is, therefore, essential.
As well as technical network failures, excessive bandwidth consumption by servers, applications, or users can lead to damaging losses for the company, in terms of quality of service and direct financial impact (in the case of production stoppage and/or SLA penalties).
For your information, a network that is unavailable or difficult to access 1% of the time is 87 hours of work per employee impacted.
It is therefore essential to be able to detect the risks of incidents or the optimizations to be made before any technical failure of the network.
The monitoring of the network activity also makes it possible to be correctly informed in the event of a problem and to implement the right action plan quickly.
What to expect from a monitoring solution?
A qualitative monitoring of the bandwidth should indicate the use and consumption of the bandwidth by your IS, detect network congestion and help you identify the resources to be implemented so that the bandwidth capacity corresponds to your actual needs.
In addition to its ability to detect technical failures in the network and to target bandwidth usage, ServiceNav allows the user to observe bandwidth consumption, control network traffic and monitor the availability, uptime and performance of network components.
The phenomenon of bottleneckThe network performance issue, which occurs when there is not enough bandwidth available for all data packets to be delivered on the network in an optimal time frame.
Serious monitoring of bandwidth consumption and usage allows early identification of bottlenecks which, once formed, are one of the main sources of network performance degradation, and the applications that depend on them.
Detecting bottlenecks with ServiceNav
Putting the right controls in place
To detect excessive consumption, it is possible to configure consumption monitoring based on Top Lists. ServiceNav provides three types of Top Lists, based on the technology NetFlow and sFlow:
- Top Talkers: Identify the IPs that require the most bandwidth
- Top Connections: Identify the data flows that require the most bandwidth
- Top Protocols: Identify the applications that require the most bandwidth
This implementation is done using the service models NetworkAnalysis-NetFlow-TOPList / NetworkAnalysis-sFlow-TOPList s, associated with the Network Analysis widget.
Analyze the results
Analysis of the data returned by these checks provides a detailed view of network traffic, and identifies users, applications and protocols that are consuming bandwidth in an abnormal manner.
This makes it easier to configure bandwidth usage (QoS) policies, optimize your ISP costs, and ensure adequate bandwidth for your mission-critical applications and services, thereby maximizing your quality of service.
