Infrastructure monitoring is crucial for ensuring software reliability and reducing costs by collecting and analyzing data from various components such as network, server, application performance, and cloud infrastructure. To achieve this, companies can use popular tools like Telegraf, OpenTelemetry, InfluxDB, Prometheus, Graphite, Grafana, Apache Superset, Jaeger, and others to collect, store, and analyze data. A suitable monitoring system should be scalable, extensible, and user-friendly, allowing teams to view and manage their infrastructure effectively. By setting up a robust infrastructure monitoring system, companies can gain insights into the performance and health of their infrastructure, reduce downtime, and optimize resources, ultimately leading to cost savings and improved reliability.
