Works across:

Quick Start​

Set up a slack alert channel to receive alerts from proxy.

Step 1: Add a Slack Webhook URL to env​

Get a slack webhook url from https://api.slack.com/messaging/webhooks

You can also use Discord Webhooks, see here

Set SLACK_WEBHOOK_URL in your proxy env to enable Slack alerts.

export SLACK_WEBHOOK_URL="https://hooks.slack.com/services/<>/<>/<>"

Step 2: Setup Proxy​

general_settings: 
    alerting: ["slack"]
    alerting_threshold: 300 # sends alerts if requests hang for 5min+ and responses take 5min+ 
    spend_report_frequency: "1d" # [Optional] set as 1d, 2d, 30d .... Specifiy how often you want a Spend Report to be sent

Start proxy 

$ litellm --config /path/to/config.yaml

Step 3: Test it!​

curl -X GET 'http://0.0.0.0:4000/health/services?service=slack' \
-H 'Authorization: Bearer sk-1234'

Advanced​

Redacting Messages from Alerts​

By default alerts show the messages/input passed to the LLM. If you want to redact this from slack alerting set the following setting on your config

general_settings:
  alerting: ["slack"]
  alert_types: ["spend_reports"] 

litellm_settings:
  redact_messages_in_exceptions: True

Add Metadata to alerts​

Add alerting metadata to proxy calls for debugging. 

import openai
client = openai.OpenAI(
    api_key="anything",
    base_url="http://0.0.0.0:4000"
)

# request sent to model set on litellm proxy, `litellm --model`
response = client.chat.completions.create(
    model="gpt-3.5-turbo",
    messages = [], 
    extra_body={
        "metadata": {
            "alerting_metadata": {
                "hello": "world"
            }
        }
    }
)

Opting into specific alert types​

Set alert_types if you want to Opt into only specific alert types. When alert_types is not set, all Default Alert Types are enabled.

👉 See all alert types here

general_settings:
  alerting: ["slack"]
  alert_types: [
    "llm_exceptions",
    "llm_too_slow",
    "llm_requests_hanging",
    "budget_alerts",
    "spend_reports",
    "db_exceptions",
    "daily_reports",
    "cooldown_deployment",
    "new_model_added",
  ]

Set specific slack channels per alert type​

Use this if you want to set specific channels per alert type

This allows you to do the following

llm_exceptions -> go to slack channel #llm-exceptions
spend_reports -> go to slack channel #llm-spend-reports

Set alert_to_webhook_url on your config.yaml

model_list:
  - model_name: gpt-4
    litellm_params:
      model: openai/fake
      api_key: fake-key
      api_base: https://exampleopenaiendpoint-production.up.railway.app/

general_settings: 
  master_key: sk-1234
  alerting: ["slack"]
  alerting_threshold: 0.0001 # (Seconds) set an artifically low threshold for testing alerting
  alert_to_webhook_url: {
    "llm_exceptions": "https://hooks.slack.com/services/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",
    "llm_too_slow": "https://hooks.slack.com/services/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",
    "llm_requests_hanging": "https://hooks.slack.com/services/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",
    "budget_alerts": "https://hooks.slack.com/services/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",

  }

litellm_settings:
  success_callback: ["langfuse"]

Test it - send a valid llm request - expect to see a llm_too_slow alert in it's own slack channel

curl -i http://localhost:4000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-1234" \
  -d '{
    "model": "gpt-4",
    "messages": [
      {"role": "user", "content": "Hello, Claude gm!"}
    ]
}'
