Missing Metric Coverage for CloudWatch, Enhanced Monitoring, and Performance Insights in RDS Exporter

[VamilP]

Hi team,

First of all, thank you for your work on this exporter — it's been very helpful in integrating RDS metrics into our observability stack.

While working on aligning our CloudWatch and Enhanced Monitoring metrics with the qonto-rds-exporter, I noticed that some metrics commonly available in CloudWatch, Enhanced Monitoring, and Performance Insights do not seem to have corresponding metrics exposed by the exporter. Below is a list for reference:

CloudWatch Metrics:

BinlogDiskUsage

DBLoadRelativeToNumvCPUs

DiskQueueDepth

LVMReadIOPs

LVMWriteIOPs

Write Latency

Read Latency

Network Receive Throughput

Network Write Throughput

Enhanced Monitoring Metrics:

Active Memory

CPU User

CPU Total

Task Running

Performance Insights Metrics:

IOLatency

EBS IO read operations by volume (Per second)

EBS IO write operations by volume (Per second)

InnoDB history list length

Deadlocks

Binlog disk usage (Bytes)

Would it be possible to confirm whether support for any of these metrics is currently planned, or if there’s guidance on how these could be mapped or extended manually?

Thanks again for your work and support!
