Dubidoc Signature Agent

Monitors the Dubidoc Signature Agent — a Go service that manages Ukrainian digital signature keys and handles cryptographic signing requests.

Panels:

• Key Health — loaded vs. failed keys at a glance, certificate expiry countdown per key (days remaining, color-coded red/yellow/green), overall HTTP throughput, and signing success rate
• HTTP Traffic — request rate over time broken down by key and by response status
• Signing Operations — signing rate by result (success / error), per-key success rate %, and latency histogram (p50 / p95 / p99) for cryptographic operations
• Go Runtime — goroutine count, heap memory (alloc / in-use / sys), GC pause duration
