What different kinds of metrics do you use for measuring defects on software development?

Here are some metrics tracked by our software team to measure defects and the quality of deliverables:
• Number of defects in the release
• Defect escape rate between development to staging and staging to production
• Defect severity rate
• Defect resolution time, indicating how many releases have the same defect
We use defect density ratings (industry is 1/1000 lines of code written) and we report on our defect rate. We track this per team and overall. We also track SLA remediation of defects by risk rating (high/medium/low) and report on trends. We also track defect based on internally versus vendor developed. We have been thinking of using defect impact to release cycle timing, but it seems our SLAs have that covered.
