Send logs from Grafana Alloy or Promtail to UptimeEye

local.file_match "app" {
  path_targets = [{ __path__ = "/var/log/myapp/*.log", service = "myapp", env = "prod" }]
}

loki.source.file "app" {
  targets    = local.file_match.app.targets
  forward_to = [loki.write.uptimeeye.receiver]
}

loki.write "uptimeeye" {
  endpoint {
    url          = "https://logs.uptimeeye.com/v1/ingest/loki/api/v1/push"
    bearer_token = sys.env("UPTIMEEYE_KEY")
  }
  external_labels = { host = constants.hostname }
}

clients:
  - url: https://logs.uptimeeye.com/v1/ingest/loki/api/v1/push
    bearer_token: ue_ingest_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
    external_labels:
      env: prod

scrape_configs:
  - job_name: myapp
    static_configs:
      - targets: [localhost]
        labels:
          service: myapp
          __path__: /var/log/myapp/*.log

Fields you get

These show up in the fields panel and can be used in every filter:

• every Loki label (service, env, host, job, filename)
• structured metadata, when your pipeline sets it

Tips

• Keep label cardinality low, exactly as you would for Loki. Put request ids and user ids into the line, not into labels.
• Alloy's loki.process stages (stage.multiline, stage.json) run before the write, so parsed fields reach UptimeEye as fields.

FAQ

Can I send to Loki and UptimeEye at the same time?

Yes. List both under clients: in Promtail, or forward to two loki.write components in Alloy.

Where do I get the ingest key?

In the app under API Keys → New API Key → type “Log ingest”. The key starts with ue_ingest_ and is shown once. Management keys (ue_live_) are refused by the ingest endpoint.

How do I check that logs arrive?

Open Logs in the app, pick the 15m range and search for service:=<your service>. New lines are searchable within about a second; Live tail shows them with a ~6 s delay.
