Lambda Log Patterns
8 patterns smplogs detects in AWS Lambda CloudWatch logs.
CRITICAL / HIGH / ELEVATED
Elevated Error Rate
Invocation failure rate above the recommended 1% threshold.
HIGH / ELEVATED
DynamoDB Throttling Errors
ProvisionedThroughputExceededException failures in Lambda logs.
HIGH / ELEVATED
High Cold Start Rate
Percentage of invocations that are cold starts with elevated init duration.
CRITICAL / HIGH
Function Timeouts
'Task timed out' errors hitting the configured timeout limit.
CRITICAL / HIGH
High Memory Utilization
Peak memory approaching or exceeding allocation, risking OOM.
ELEVATED
Slow Execution Times
P99 duration exceeds 3 seconds, indicating performance bottlenecks.
HIGH / ELEVATED
Connection Failures
Failures connecting to downstream services (ECONNREFUSED, DNS).
ELEVATED
Upstream Service Failures
Errors from downstream APIs or services (HTTP 5xx, SDK errors).
