LPWAN (Low Power Wide Area Network), also known as LPWA or LPN, is a wireless data transport protocol that is now understood as one of the basic protocols for the implementation of IoT. In order to have a better idea of the relevance of LPWAN we can consider the prediction made by statisca.com of a steady increase in the number of LPWAN devices connected around the world, expecting this number to reach around 3.5 billion devices by 2021.
If you’ve been paying attention, you know that although collecting and reviewing metrics and logs is a core part of running a stable and successful service, access to raw events and the ability to search and pivot on any dimension of your production environment, no matter how high-cardinality, is what will help your team debug and troubleshoot new problems and outages more quickly.
Nowadays, we need to pay for almost every service we use. Starting with our operating systems, antivirus software, for which we need to pay for a license to use. Also, if we wish to use various online services, we need to register an account on their website. Furthermore, we need to pay to be able to use the service entirely.
Following last week’s article about monitoring CPU usage using Performance Monitor counters, this post concerns the “\Paging File\% Usage” counter.

In my previous post, I talked about the real costs of alert fatigue — the toll it can take on your engineers as well as your business — and some suggestions for rethinking alerting. In part 2 of this series, I’ll share some best practices for fine-tuning Sensu to help reduce alert fatigue.
Custom Metrics (JMX, Golang expvar, Prometheus, statsd or many other), APM and Opentracing are different approaches on how to instrument code in order to monitor health, performance and troubleshoot your application more easily.
