Amazon CloudWatch
BetaThis source is currently in beta. It works end to end, but you may still hit rough edges. Let us know if you do.
Let AI connect your sources for you
Skip the manual setup — run this in your project and the wizard auto-detects your databases and APIs and connects them to PostHog.
Connect Amazon CloudWatch to PostHog to sync your data into the PostHog data warehouse for analysis and modeling.
Sync CloudWatch log events, alarms, alarm history and metric datapoints from one AWS region into the PostHog Data warehouse.
Create an IAM user or role with the logs:DescribeLogGroups, logs:FilterLogEvents, cloudwatch:DescribeAlarms, cloudwatch:DescribeAlarmHistory and cloudwatch:GetMetricData permissions, then paste its access key ID and secret access key. Add a session token too if you are using temporary credentials.
Log events sync from the log groups you list, or from every log group in the region (up to 50) when the list is empty. A log group or metric query added later syncs from the next sync on; resync the table to backfill its history. Any log delivered to CloudWatch Logs works, including Bedrock model invocation logs and CloudFront standard logs. Metric datapoints sync for the metric queries you configure as JSON, for example [{"id": "cpu", "namespace": "AWS/EC2", "metric_name": "CPUUtilization", "dimensions": {"InstanceId": "i-0123456789abcdef0"}, "stat": "Average", "period": 300}]. S3 Storage Lens metrics live in the AWS/S3/Storage-Lens namespace. Older datapoints come back at the resolution CloudWatch keeps for them: 5 minutes after 15 days and 1 hour after 63 days.
