Problem Definition

It's not easy to understand and troubleshoot connectivity and latency to the Shared Home Filesystem. Also, we want to measure latency of the local filesystem where Lucene index is located, since this is crucial for application performance.

Suggested Solution

Create a latency metrics for:

• Local disk synthetic write - median time to write sample data to the local home
• Local disk Lucene write - metric reports the time of flushing Lucene index buffer to the local disk. It’s based on real traffic and represents the current status and performance of the Lucene subsystem. This metric is updated only when the Lucene buffer is persisted - usually after index updates.
• Shared disk synthetic write - median time to write sample data to the shared home
