gce/Disk Avg Io Latency Check
Product: Compute Engine
Step Type: AUTOMATED STEP
Description
None
Failure Reason
The performance of the disk ‘{disk_name}’ is currently degraded due to high IO latency exceeding optimal thresholds. This may result in slower read/write speeds and overall reduced performance.
Failure Remediation
Disk I/O latency is the time it takes for a read or write operation to complete on a disk. High disk I/O latency can significantly impact the performance of your applications and workloads running on the instance, leading to slow response times, increased processing time, and overall sluggishness.
Potential Bottlenecks -
-
Disk Type: To optimize disk performance, ensure your disk type is appropriate for your workload and provides acceptable latency for your system architecture. Choosing the right disk type can significantly impact performance. https://cloud.google.com/compute/docs/disks
-
Workload: The nature of your workload also influences latency. Workloads with many small, random I/O operations will generally have higher latency than those with sequential I/O
Optimize Disk Usage:
- Reduce I/O Operations: Optimize your applications and database queries to minimize the number of disk I/O operations.
- Increase I/O Request Size: Larger I/O requests can be more efficient than many small ones. Consider adjusting your application or database settings to increase the I/O request size.
- Caching: Implement caching mechanisms to reduce the need to access the disk for frequently used data.
