Final answer:
You can set various alarms on storage metrics to monitor capacity thresholds, performance metrics, and health checks, ensuring proactive management of your storage systems.
Step-by-step explanation:
When managing storage metrics, there are a variety of alarms you can set to help monitor your storage systems. It is essential to set these alarms to ensure that you are proactively notified about potential issues that could affect data integrity or access. The most common alarms include capacity thresholds, where you get alerted when storage space falls below a certain percentage, performance metrics such as IOPS (input/output operations per second) and latency, as well as health checks which can alert you to hardware malfunctions or network connectivity issues.
For example, you might want to set an alarm when the disk usage exceeds 80% of its capacity, indicating it's time to consider adding more storage or archiving old data. Another practical alarm could be set based on abnormal performance patterns, like a sudden drop in IOPS or an increase in latency which might indicate a problem with the storage media or the network. Lastly, setting up health check alarms can notify you of failed drives or other critical conditions requiring immediate attention.
