Set Up Monitoring Alerts for Slack, Chatwork, and LINE

Get Instant Downtime Alerts in the Tools You Already Use

The most sophisticated monitoring setup is worthless if nobody sees the alerts. Email notifications get buried. Relying on a dashboard somebody checks "when they remember" is not a strategy. The solution is routing alerts directly to the chat tools your team lives in every day.

This guide walks through setting up Slack, Chatwork, and LINE alerts with Miterl.

Slack Alert Setup

Slack is the go-to for most development teams. Miterl connects via a standard Incoming Webhook.

Steps:

1. In your Slack workspace, open the target channel and add the Incoming Webhooks app
2. Copy the generated Webhook URL
3. In Miterl's notification settings, select Slack and paste the URL

# Register a Slack webhook channel in Miterl
curl -X POST https://api.miterl.com/v1/channels \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "type": "slack",
    "name": "Engineering Alerts",
    "webhook_url": "https://hooks.slack.com/services/T00/B00/xxxxx"
  }'

Chatwork Alert Setup

Chatwork is widely used by agencies and their clients in the Japanese market. Miterl integrates natively with the Chatwork API.

Steps:

1. Go to Chatwork's "Service Integration" settings and generate an API token
2. Find the Room ID of your target room (the number after #!rid in the URL)
3. In Miterl's notification settings, select Chatwork and enter the API token and Room ID

# Register a Chatwork notification channel
curl -X POST https://api.miterl.com/v1/channels \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "type": "chatwork",
    "name": "Client A Alerts",
    "api_token": "YOUR_CHATWORK_TOKEN",
    "room_id": "123456789"
  }'

LINE Alert Setup

LINE Notify delivers push notifications directly to your phone. This is ideal for high-priority sites where you need to know about outages even when you are away from your desk.

Steps:

1. Log in to LINE Notify and generate a token
2. Choose a notification target -- either a group or "1-on-1 with LINE Notify"
3. In Miterl's notification settings, select LINE and enter the token

Routing Alerts by Purpose: A Strategy for Agencies

When managing multiple client sites, sending every alert to a single channel creates noise. Instead, route alerts based on audience and urgency.

With Miterl, you can assign multiple notification channels to a single monitor. For example, send alerts to Slack for your engineering team and simultaneously to LINE for on-call escalation.

Always Test Your Notifications

After configuring a channel, send a test notification before trusting it in production. Miterl's dashboard includes a "Send Test" button for each configured channel -- use it.
