In which situation should lower thresholds be set for disks?

Setting lower thresholds for disks is particularly important for mission-critical services within your infrastructure. This is because these services require a high level of performance and reliability since they often support essential business functions or customer-facing applications. By establishing lower thresholds, you can ensure that any potential issues related to disk performance or capacity are identified and addressed promptly before they lead to downtime or degraded service quality.

In mission-critical environments, proactive monitoring and early alerts regarding disk utilization are vital to maintaining system health and operational efficiency. Lower thresholds serve as an early warning system that allows IT teams to take corrective actions, such as optimizing storage, reallocating resources, or planning for expansions, thereby preventing any negative impact on service availability or performance.

Setting lower thresholds may not be as critical in development or testing environments, where flexibility and experimentation are often prioritized over strict performance requirements. In these scenarios, the emphasis is typically on functionality rather than the reliability that mission-critical applications require, making a different threshold strategy more appropriate.
