Health Status

Consensus: In Consensus (9/9 Directory Auths)
Flags: Running, Valid, V2Dir, Fast (4)
BW Verified: 1/7 BW Auths Measured 46 Kbit/s Median
Stability: Overloaded | DOWN 3h 46m 41s ago | UP 36% (1M)

Reachability: IPv4: 9/9 (Directory Auths)
First Seen: 9y 10mo 2w ago
BW Weight: 0.00% of Network | 46 Mbit/s Observed By Relay
Version: 0.4.9.12 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 25.9% 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 25.9% 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.
Low bandwidth authority measurements : Only 1/7 bandwidth authorities measured this relay. Minimum 3 measurements needed for accurate consensus weight.
Suggestion: Low measurement count can indicate connectivity issues. Check: 1) Relay is reachable from multiple geographic locations, 2) ORPort accepts connections from bandwidth scanners, 3) RelayBandwidthRate in torrc matches actual capacity. New relays may take 1-2 days to be measured by all authorities.
File Descriptor Exhaustion : Relay ran out of file descriptors at 2026-09-20 02:00 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.

— = 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.
