Issues Detected:
-
Guard: bandwidth below threshold
: 2/9 authorities credit this relay with enough bandwidth for Guard (5 needed): at least 16.8 Mbit/s (AuthDirGuardBWGuarantee) or a place in their top 25% (80.0 Mbit/s – 272.0 Mbit/s). bastet, moria1 and tor26 measured this relay at 8.8 Mbit/s – 13.6 Mbit/s. dizum, faravahar, longclaw and maatuska used the relay-reported 12.6 Mbit/s.
Suggestion: Guard requires a bandwidth of at least AuthDirGuardBWGuarantee (16.8 Mbit/s by default) or one in the top 25% of relays, judged by each authority the same way as for Fast. To increase bandwidth: 1) Ensure adequate upstream capacity, 2) Check RelayBandwidthRate/RelayBandwidthBurst in torrc, 3) Monitor with Nyx. -
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. -
Write Bandwidth Limit Hit
: Write rate-limit counter is 2 (configured rate 12.58 Mbit/s). Read and write counters increment at most once per minute per direction. They are not a count of blocked connections, the duration of throttling, or necessarily the number of events in the last 24 hours.
Suggestion: Inspect BandwidthRate and BandwidthBurst (the values reported with this hit), any relay-specific caps such as RelayBandwidthRate and RelayBandwidthBurst, the intended bandwidth budget, and actual uplink headroom. A rate-limit report is not evidence of ISP throttling. After checking that evidence and the capacity you meant to offer, review whether those limits should change. MetricsPort: tor_relay_load_global_rate_limit_reached_total{side="read"} and {side="write"}. Increases indicate additional global token-bucket limit events. -
Read Bandwidth Limit Hit
: Read rate-limit counter is 929 (configured rate 12.58 Mbit/s). Read and write counters increment at most once per minute per direction. They are not a count of blocked connections, the duration of throttling, or necessarily the number of events in the last 24 hours.
Suggestion: Inspect BandwidthRate and BandwidthBurst (the values reported with this hit), any relay-specific caps such as RelayBandwidthRate and RelayBandwidthBurst, the intended bandwidth budget, and actual uplink headroom. A rate-limit report is not evidence of ISP throttling. After checking that evidence and the capacity you meant to offer, review whether those limits should change. MetricsPort: tor_relay_load_global_rate_limit_reached_total{side="read"} and {side="write"}. Increases indicate additional global token-bucket limit events.
Notes:
- Rate Limit Configuration: Configured limits: Rate=12.58 Mbit/s, Burst=1.1 GB. Counters: Write=2, Read=929. These values are BandwidthRate and BandwidthBurst from the extra-info descriptor. RelayBandwidthRate and RelayBandwidthBurst are additional torrc caps, not the names of these values. Burst is a quantity of bytes.

Read and write counters increment at most once per minute per direction. They are not a count of blocked connections, the duration of throttling, or necessarily the number of events in the last 24 hours. Rate is BandwidthRate and follows this site’s bits/bytes setting. Burst is BandwidthBurst, already a byte quantity. RelayBandwidthRate and RelayBandwidthBurst are extra torrc caps, not the names of these values. A hit stays eligible for 24 hours.
What to check
-
Configured bandwidth limits
Inspect BandwidthRate and BandwidthBurst (the values reported with this hit), any relay-specific caps such as RelayBandwidthRate and RelayBandwidthBurst, the intended bandwidth budget, and actual uplink headroom. A rate-limit report is not evidence of ISP throttling. After checking that evidence and the capacity you meant to offer, review whether those limits should change.MetricsPort:
tor_relay_load_global_rate_limit_reached_total{side="read"} and {side="write"}— Increases indicate additional global token-bucket limit events.
About these reports and MetricsPort
Allium’s eligibility windows are applied to the reported timestamps: 72 hours for general overload and file-descriptor exhaustion, 24 hours for a rate-limit hit. A report at the cutoff is historical. An older report can remain visible after Onionoo or Allium’s cache still has it. The cutoff does not prove the relay recovered at that moment. Allium caches the bandwidth document for 12 hours by default. The snapshot time is when Onionoo published that document. It is not the relay’s event time, and it is not necessarily the extra-info publication time. Cache age is how old Allium’s copy is.
MetricsPort counters are cumulative. Compare samples, and account for process restarts. A nonzero total alone does not show ongoing activity. Gauges describe current values. An unavailable metric is unknown, not zero. Allium does not have this relay’s MetricsPort readings and does not invent them.
The port below is an example for an endpoint you have already configured. MetricsPort must be enabled with restricted access and must not be exposed publicly. Setup stays in the Tor overload troubleshooting guide.

N/T = this authority does not test IPv6 • — = not in this vote • Format: relay value | authority threshold • WFU = Weighted Fractional Uptime • TK = Time Known • Bandwidth source: (M) bandwidth-scanner measurement, (R) relay-reported, (U) unmeasured, counted as 0
Bandwidth Values Explained:
Measured (M) = An authority's bandwidth-scanner measurement of your relay (
Relay-reported (R) = The bandwidth your relay advertises: the lower of its observed bandwidth and its rate limit, capped at 10 MB/s (
Not published = The authority has no measurement of your relay in its vote and ignores relay-reported bandwidth, yet it voted Fast or its vote has no measurements at all: it judges your relay by a measurement kept from an earlier bandwidth file (0 if none), which its vote doesn't show.
Why different? A low measurement means the bandwidth scanners see your relay underperforming compared with other relays that report a similar speed. Votes list both values in kilobytes per second. Rules: Assigning flags in a vote, Computing a consensus.
Measured (M) = An authority's bandwidth-scanner measurement of your relay (
Measured= in its vote). An authority that has one uses it for the Fast and Guard flags, and the consensus weight is the median of these measurements when 3 or more authorities have one.Relay-reported (R) = The bandwidth your relay advertises: the lower of its observed bandwidth and its rate limit, capped at 10 MB/s (
Bandwidth= in every vote). An authority without a measurement uses it for flags, unless it has measurements for enough other relays (ignoring-advertised-bws=1); then your relay counts as 0 (U). It sets the consensus weight only when fewer than 3 authorities measured the relay, capped at 20 KB/s (maxunmeasuredbw) while 3 or more authorities publish measurements.Not published = The authority has no measurement of your relay in its vote and ignores relay-reported bandwidth, yet it voted Fast or its vote has no measurements at all: it judges your relay by a measurement kept from an earlier bandwidth file (0 if none), which its vote doesn't show.
Why different? A low measurement means the bandwidth scanners see your relay underperforming compared with other relays that report a similar speed. Votes list both values in kilobytes per second. Rules: Assigning flags in a vote, Computing a consensus.
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.
