dannygroenewegen 067f013fb7 fix: don't expose Alloy's web UI by default, but optionally with compose.alloy-webui.yml 2026-08-17 14:48:44 +02:00
dannygroenewegen 536fa7f37d fix Traefik dashboard 2026-08-17 13:37:27 +02:00
dannygroenewegen fafd1f89f0 fix: discover containers by task instead of service for scraping 
Swarm service discovery misses dnsrr-mode services like traefik; switch
to swarm task discovery, scoped to this host, with a stable instance
label across redeploys and a default port when none is labeled.
 2026-08-10 21:24:38 +02:00
dannygroenewegen 7ab6cc74be fix: make swarm/stacks dashboards work with old and new metric data 
Replace node_meta-based joins with label_replace() of the instance
label, so old (pull-model) and new (Alloy push) series for the same
host render as one continuous series. Each rewritten query has a TODO
noting the simpler form to use once old data ages out of retention.

dannygroenewegen 0f989c4567 fix: drop unfiltered discovery.docker.containers.targets from default scrape 
prometheus.exporter.cadvisor.docker.targets already reports resource
metrics for every container on the host. The unfiltered discovery just
added targets with internal overlay IPs, most of which failed to
scrape anything useful.

dannygroenewegen 402e022114 feat: separate scrape_auth secret, configurable usernames 
Added an optional scrape_auth secret for authenticating scrapes of
containers that opt in via prometheus.io/auth labels, no longer
reusing the basic_auth secret meant for Prometheus/Loki writes.

Made usernames for both write endpoints and authenticated scraping
configurable in .env.

dannygroenewegen f2310f2b86 improve alloy config and match with main branch 
- Restrict Alloy UI to loopback
- Narrow volume mounts: drop /dev, reduce /var/run to docker.sock:ro
- Replace HTTP scrape of :12345 with prometheus.exporter.self
Match with main branch (node-exporter / promtail / cadvisor):
- Add docker_only and explicit enabled_metrics to cadvisor exporter
- Match node-exporter collector config
- Match promtail relabeling (container_name, container_id, stack_namespace,
  service_name) and external hostname label
- Add SYSLOG_FILES option to tail /var/log/*log (matches promtail)
- Fix journal path and syslog listener address
