# Why Netdata > Any performance monitoring solution that does not go down to per second > collection and visualization of the data, is useless. > It will make you happy to have it, but it will not help you more than that. Netdata is built around 4 principles: 1. **[Per second data collection for all metrics.](/docs/why-netdata/1s-granularity.md)** _It is impossible to monitor a 2 second SLA, with 10 second metrics._ 2. **[Collect and visualize all the metrics from all possible sources.](/docs/why-netdata/unlimited-metrics.md)** _To troubleshoot slowdowns, we need all the available metrics. The console should not provide more metrics._ 3. **[Meaningful presentation, optimized for visual anomaly detection.](/docs/why-netdata/meaningful-presentation.md)** _Metrics are a lot more than name-value pairs over time. The monitoring tool should know all the metrics. Users should not!_ 4. **[Immediate results, just install and use.](/docs/why-netdata/immediate-results.md)** _Most of our infrastructure is standardized. There is no point to configure everything metric by metric._ Unlike other monitoring solutions that focus on metrics visualization, Netdata's helps us troubleshoot slowdowns without touching the console. So, everything is a bit different. [](<>)
