check / check (push) Waiting to run
The spec names every fault that stops the start, runs step 15 for every request but the health check, and states each of the fourteen repeated requirements once. docs/alerts.md says which alerts have an empty client and netblock and what a summary's detail holds; docs/settings.md lists the settings that need a lookup and points at step 3 for the two static lists. The README and the spec now travel in one branch, so the README never names a spec section that does not exist yet. Model: fable-5-1

# The metrics
|
|
|
|
What `GET /_smallwebwaf/metrics` answers with. "Metrics endpoint" in
|
|
[`SPEC.md`](../SPEC.md) describes the endpoint. Prometheus keeps the `instance`
|
|
label as `exported_instance` unless the scrape sets `honor_labels: true`.
|
|
|
|
## Traffic
|
|
|
|
- `smallwebwaf_requests_total`, `smallwebwaf_request_bytes_total` and
|
|
`smallwebwaf_response_bytes_total`, by `status_class` such as `2xx` and by
|
|
`action`;
|
|
- `smallwebwaf_request_duration_seconds` and
|
|
`smallwebwaf_upstream_duration_seconds`, as histograms;
|
|
- `smallwebwaf_requests_in_flight`.
|
|
|
|
## Limits and bans
|
|
|
|
- `smallwebwaf_rate_limit_hits_total`, by `window` and by `kind` (`requests`,
|
|
`bytes` or `refusals`);
|
|
- `smallwebwaf_size_and_time_limit_hits_total`, by `limit`, the setting passed;
|
|
- `smallwebwaf_offences_total`, by `kind`;
|
|
- `smallwebwaf_bans_made_total`, by `cause`;
|
|
- `smallwebwaf_active_bans` and `smallwebwaf_permanent_bans`.
|
|
|
|
## Attack detection
|
|
|
|
- `smallwebwaf_rule_matches_total`, by `rule_id` and `action`, and
|
|
`smallwebwaf_rules_loaded`;
|
|
- `smallwebwaf_waf_matches_total`, by `mode` and `rule_id`, for the rules that
|
|
fired.
|
|
|
|
## Countries and AS numbers
|
|
|
|
For the `SWWAF_METRICS_TOP_N` busiest of each, the rest as `other`:
|
|
|
|
- `smallwebwaf_country_requests_total`,
|
|
`smallwebwaf_country_request_bytes_total`,
|
|
`smallwebwaf_country_response_bytes_total` and
|
|
`smallwebwaf_country_list_refusals_total`, by `country`;
|
|
- `smallwebwaf_asn_requests_total`, `smallwebwaf_asn_request_bytes_total` and
|
|
`smallwebwaf_asn_response_bytes_total`, by `asn`.
|
|
|
|
## Lookups
|
|
|
|
- `smallwebwaf_geojs_requests_total` and `smallwebwaf_geojs_failures_total`;
|
|
- `smallwebwaf_geojs_unanswered_total`: the requests that needed an answer and
|
|
went on without it;
|
|
- with the file source,
|
|
`smallwebwaf_lookup_database_last_read_timestamp_seconds` and
|
|
`smallwebwaf_lookup_database_read_failures_total`.
|
|
|
|
## Reputation sources
|
|
|
|
By `source`: each list's URL, each zone, and `abuseipdb`:
|
|
|
|
- `smallwebwaf_reputation_hits_total`, `smallwebwaf_reputation_queries_total`
|
|
and `smallwebwaf_reputation_failures_total`;
|
|
- `smallwebwaf_reputation_last_fetch_timestamp_seconds`, for a list;
|
|
- `smallwebwaf_reputation_daily_budget_remaining`, for AbuseIPDB.
|
|

|
|
`smallwebwaf_state_file_last_write_timestamp_seconds` and
|
|
`smallwebwaf_state_file_size_bytes`;
|
|
- `smallwebwaf_state_file_edits_taken_in_total` and
|
|
`smallwebwaf_state_file_edits_set_aside_total`;
|
|
- `smallwebwaf_tracked_clients`: the clients in the table.
|
|
|
|
## Remote log, alerts and the process
|
|
|
|
- while a syslog server is set, `smallwebwaf_remote_log_lines_sent_total`,
|
|
`smallwebwaf_remote_log_lines_dropped_total` and
|
|
`smallwebwaf_remote_log_buffer_depth`;
|
|
- by `destination`, `smallwebwaf_alerts_sent_total`,
|
|
`smallwebwaf_alerts_failed_total`, `smallwebwaf_alerts_suppressed_total` and
|
|
`smallwebwaf_alerts_dropped_total`;
|
|
- Go's own `go_` metrics and the process's `process_` metrics.
