prometheus-sns-lambda-slack

Receive prometheus alerts via AWS SNS and publish then to slack channel.

TL;DR

At the time of writing, Amazon-managed Prometheus does not support sending alerts to Slack.

The "official" way of integration is Prometheus->SNS->Lambda->Slack [1].

This repo is one of many possible implementations of this idea.

export SLACK_TOKEN=XXXX-NNNNNNNNNNNNN-NNNNNNNNNNNNN

./prometheus-sns-lambda-slack lambda \
  --dynamo-db-name slack-alerts \
  --slack-channel incidents \
  --slack-channel-id XXXXXXXXXXX

Features

• Groups messages into threads (based on message labels).
• Deduplicates the messages (AWS managed grafana seems to be 3 instances in HA setup, which means that each alert sent by grafana comes as a triplet).
• Can filter-out alerts based on their kind.
• Flags alerts that got resolved with green check-box emoji reaction.
