Hello guys! I’m a bit frustrated at the moment to get alert-notifications on discord.

# Context

I’m on NixOS and I’m configuring prometheus by using `nix`, however, I’ll post the generated config files here and not the config files written in nix.

I followed [this tutorial](https://promlabs.com/blog/2022/12/23/sending-prometheus-alerts-to-discord-with-alertmanager-v0-25-0/) and even got some messages on discord in the beginning but after the first 4 messages I didn’t retrieve any messages anymore…

# Setup

So, here’s my config:

## `test_alert.yaml`

Or rather `/nix/store/3dpnn32gyxjknkng37lljx1354m43xrh-rules-checkrules-checked` as in the second entry in `rule_files` from the prometheus config file:

```yml
groups:
- name: demo-service-alerts
  rules:
  - alert: DemoServiceHighErrorRate
    expr: |
      (
        sum without(status, instance) (
          rate(demo_api_request_duration_seconds_count{status=~"5..",job="demo"}[1m])
        )
      /
        sum without(status, instance) (
          rate(demo_api_request_duration_seconds_count{job="demo"}[1m])
        ) * 100 > 0.5
      )
    for: 1m
    labels:
      severity: critical
    annotations:
      title: 'High 5xx rate for {{ $labels.method }} on {{ $labels.path }}'
      description: 'The 5xx error rate for path {{$labels.path}} with method {{ $labels.method }} in {{ $labels.job }} is {{ printf "%.2f" $value }}%.'

```

## Prometheus config file

From the prometheus → status → configuration page:

```

## `alert-manager.yaml`

The config file for the alert-manager. Its content is in json.

```yml
{
  "receivers": [
    {
      "discord_configs": [
        {
          "send_resolved": true,
          "webhook_url_file": "/run/agenix/discord-webhook"
        }
      ],
      "name": "discord"
    }
  ],
  "route": {
    "group_by": [
      "alertname",
      "job"
    ],
    "group_interval": "5m",
    " group_wait": "30s",
    "receiver": "discord",
    "repeat_interval": "3h"
  }
}

```

I also verified the URI in `/run/agenix/discord-webhook` and checked if the hook even worked, thanks to [this](https://stackoverflow.com/a/62301184/11035194) stackoverflow answer.

Prometheus also seems to register the events:

 ![image](https://europe1.discourse-cdn.com/flex017/uploads/prometheus/original/1X/8ff82382e6f4a5e098e824812ab36754be72289c.png)

but I’m still not getting any discord messages (I’ve created a new discord server with a webhook, assigned to a channel and as I said, the webhook works with the `curl` command as described in the stackoverflow answer which I linked).

Any help would be appreciated 🙂
