- Version
- 0.4.9.5 Recommended
Issues Detected:
-
Guard: requires Stable flag
: Guard flag requires having the Stable flag first
Suggestion: Get Stable flag by maintaining consistent uptime. Stable requires uptime and MTBF at or above network median (typically 2-3 weeks of stable running). -
Guard: WFU below threshold
: Weighted Fractional Uptime 27.9% is below 98% requirement
Suggestion: WFU measures recent uptime (recent downtime weighs more heavily). To improve: 1) Minimize restarts, 2) Use systemd with Restart=always, 3) Monitor for OOM kills, 4) Schedule updates during low-traffic periods. -
Not eligible for Stable flag
: Uptime or MTBF below network median for most authorities
Suggestion: Stable flag requires uptime/MTBF at or above network median. Keep your relay running continuously for 2-3 weeks. Avoid restarts. Use reliable hardware and network connection. -
HSDir: requires Stable flag
: HSDir flag requires having the Stable flag first
Suggestion: Get Stable flag by maintaining consistent uptime. Stable requires uptime and MTBF at or above network median (typically 2-3 weeks of stable running). Avoid restarts. -
HSDir: WFU below threshold
: WFU 27.9% below 98% required for HSDir
Suggestion: HSDir requires ≥98% WFU, Stable flag, and Time Known ≥25 hours (or ~10 days for moria1). Improve uptime consistency. -
High consensus weight deviation
: Large variation in Consensus Weight values across authorities (see 'Cons Wt' column in Per-Authority Details below)
Suggestion: Consensus weight measurements vary significantly between authorities. This can affect traffic distribution. Ensure stable network connection and consistent bandwidth availability. -
File Descriptor Exhaustion
: Relay ran out of file descriptors at 2026-03-29 04:00 UTC. This severely impacts connections and performance.
Suggestion: Increase file descriptor limits: For systemd: add "LimitNOFILE=65535" to [Service] section. For shell: ulimit -n 65535. Persistent: edit /etc/security/limits.conf.
Notes:
- Bandwidth authority measurements below majority: 3/6 bandwidth authorities measured this relay (majority is 4).

— = not tested/available • Format: relay value | authority threshold • WFU = Weighted Fractional Uptime • TK = Time Known
Bandwidth Values Explained:
Relay Reported = Your relay's self-reported bandwidth from its descriptor (observed_bandwidth). Used for flag eligibility (Guard, Fast).
Authority Measured = Bandwidth measured by authority's sbws scanner. Used for consensus weight (path selection probability).
Why different? Authorities verify your reported bandwidth independently. 6 of 9 authorities run bandwidth scanners; 3 use relay-reported values directly.

Stable Uptime (Two Data Sources):
Relay Uptime = From Onionoo API (last_restarted field). Self-reported uptime from descriptor. Same value for all authorities.
Authority Threshold = From CollecTor vote files (flag-thresholds stable-uptime). Each authority may have different thresholds.
Why two sources? Vote files contain authority thresholds but not per-relay uptime values. Onionoo aggregates relay descriptors which include uptime.
