Adjusting the DRBD Disk Monitoring Threshold in Zabbix for Physical Appliances

To ensure effective monitoring and prevent performance issues on physical appliances using DRBD (Distributed Replicated Block Device), it is recommended to adjust the threshold setting in the Zabbix monitoring system. Adjusting this threshold to be based on the average (not on peak values) disk response time values ​​and setting up alerts for when this average exceeds 100ms over a 15-minute period can help in early identification of issues that may affect system performance.
