In 1969, the first message ever sent over ARPANET, the early ancestor of the internet, was LO. We bet you can\u2019t guess why? It was supposed to be LOGIN, but the network crashed mid-word.<\/p>\n
Modern networks are usually<\/em> reliable enough to stay up for longer than the time it takes to type two characters, but the challenge is still the same. When something fails, you need to know what happened, where, and why. Network performance monitoring (NPM) is what IT teams use to check a network\u2019s vital signs, but the right approach depends on your goals, infrastructure, and team. This guide explores the concept of network monitoring in more detail, so you have all the best practices and network analysis tools<\/a> you need to keep your network healthy and your users connected.<\/p>\nTry monday service<\/a>\n"}]},{"main_heading":"Key takeaways ","content_block":[{"acf_fc_layout":"text","content":" Network performance monitoring (NPM) is the ongoing process of checking your network\u2019s \u201cvital signs\u201d to keep it healthy, available, and fast. It means keeping an eye on key metrics like bandwidth, latency, errors, and uptime, then using that information to catch slowdowns or faults before they turn into outages. In other words, it\u2019s like a health check for your network \u2014 spotting problems early so your business keeps running smoothly and your users stay happy.<\/p>\n"}]},{"main_heading":"Why is network performance monitoring important? ","content_block":[{"acf_fc_layout":"text","content":" A network can be running perfectly one moment and grinding to a halt the next. Without visibility into what\u2019s happening behind the scenes, you\u2019re left guessing at the cause. The alternative? Here\u2019s the specific value you\u2019ll achieve from an investment in network performance monitoring.<\/p>\n Downtime is often the result of small, undetected network performance issues that build up over time. An overloaded link or a configuration error can snowball into a full outage if they go unnoticed. When WhatsApp, Facebook, and Instagram went offline for 6 hours<\/a>, the outage was estimated to cost parent company Meta $100 million in lost revenue and 5% of its stock value overnight.<\/p>\n Your business might not operate at that<\/em> scale, but the principle is the same: missed performance problems can quickly halt your operations and erode customer trust. Meanwhile, network performance monitoring allows you to detect any issues before they take your systems, and your revenue, down.<\/p>\n Many cyberattacks start as subtle changes in network performance. And if you\u2019re not monitoring these warning signs, they can go unnoticed until the breach is well underway. In June 2025 alone, there were 33 publicly disclosed cybersecurity incidents<\/a>, exposing over 16 billion records.<\/p>\n Network performance monitoring identifies these anomalies early, giving security teams the critical window they need to investigate and contain threats before they cause serious damage.<\/p>\n In regulated industries like healthcare, finance, and government, even brief service interruptions can put you in breach of compliance requirements. The CrowdStrike outage<\/a> of July 2024 disrupted 759 US hospitals, with 200+ suffering outages that directly impacted patient care, and in some cases, took more than 48 hours to recover. This type of breach can mean falling foul of regulations like HIPAA, which require timely access to patient records and continuity of critical services.<\/p>\n NPM gives you visibility to document any incidents and respond quickly, so you can avoid costly fines and reputational damage.<\/p>\n\n
