How do I get meaningful metrics out of my firewall for executive reports?

Executive dashboards want "security posture" and "risk reduction." Firewalls give you packet counters and session tables. The gap is real.

You need to translate raw telemetry into business metrics. Don't start with vendor tools; start with what you need to report.
* **Throughput & Utilization:** Aggregate interface stats, but focus on peak concurrent sessions and rule hits. A rule hit count of zero is a metric—it means a stale rule.
* **Threat Activity:** Count blocked threats, but normalize it. "Blocked X malware attempts" is noise. "Blocked Y malware attempts *targeting finance servers*" is a metric. Correlate threat log counts with destination asset groups.
* **Policy Efficiency:** Track the hit ratio of your top 10 rules vs. the bottom 50%. A giant tail of rarely-hit rules increases complexity and risk.

Example: Use a scheduled task to pull hits per rule via API, then summarize.
```bash
# Pseudo-code for cron job
curl -k "https://fw-mgmt/api/?rules_hits" |
jq '.data[] | select(.hits_last_hour > 0) | {rule:.name, hits:.hits_last_hour}' > /metrics/rules_hits.json
```
Push this to a time-series DB. Graph the top rules consuming 80% of hits. The executive report becomes: "We've reduced low-utility firewall rules by 30%, lowering configuration risk."

The goal is to show change over time, not a static snapshot. Are blocked attacks trending up? Is legitimate throughput growing? That's what they need.
