One of the previous blogs explained a 3-step approach if applications, cloud services and hybrid networks are not behaving as expected.
Part of this approach is user plane, end-to-end visibility (i.e. step 2) as a way of identifying in which part of the application chains delays are coming from.
Since networks and TCP connections are the linking pin for all business applications, network visibility based on number crunching packets give IT-Ops and DevOps organizations the shortest possible problem resolution times.
This is because, assuming the right level of modelling and visualization, network packets are the most reliable source for to the point, substantiated answers on the 5 most relevant questions: (1) – what is impacted, (2) – which sites, (3) – how many users, (4) – what is failing and (5) – source-of-failure.
In this blog a detailed, hands-on explanation based on 5 cheat sheets (1 for each question) with the following content:
- Contextual aspects of the question (i.e. meaning and relevancy)
- Pointers as to what Wire Data to look for (i.e. OSI-layer 4 related, TCP events and metrics)
- An example of the representation and its interpretation.
Combined, this gives you a jump-start in providing to the point and substantiated answers to the business and your service providers.
