Glossary

Key terms and concepts used throughout AlertD documentation.

A

Agent A specialized AI component in AlertD that handles specific tasks. Examples include the EC2 Agent (for instance queries), S3 Agent (for bucket analysis), and RDS Agent (for database metrics).

AssumeRole An AWS IAM operation that allows one IAM entity to temporarily take on the permissions of another role. AlertD uses AssumeRole to access your AWS account with read-only permissions.

AWS CloudTrail An AWS service that records API calls and events in your AWS account.

AWS CloudWatch An AWS monitoring service that collects metrics, logs, and events from AWS resources. AlertD queries CloudWatch for performance data and metrics analysis.

C

CloudWatch Metrics Numeric data points collected by CloudWatch that represent the behavior of AWS resources over time. Examples include CPUUtilization, NetworkIn, and DiskReadOps.

Cross-Account Role An IAM role in one AWS account that can be assumed by an entity in a different AWS account. AlertD uses this pattern to securely access customer AWS accounts.

D

Data Stream The output produced by each step in an execution plan. Data streams can be inspected to see exactly what data was retrieved or transformed at each stage.

Dimension A name/value pair that is part of the identity of a CloudWatch metric. For example, InstanceId is a dimension for EC2 metrics.

E

Execution Plan A structured, step-by-step blueprint created by an AlertD agent to answer your question. Plans define what data to fetch, how to process it, and how to present results.

Ephemeral Token A temporary AWS STS credential that expires after a set time period (typically 1 hour). AlertD uses ephemeral tokens instead of permanent access keys for security.

F

Flappy The nickname for AlertD’s root routing agent. Flappy analyzes incoming questions and routes them to the appropriate specialist agent.

I

IAM (Identity and Access Management) AWS service for managing access to AWS resources. AlertD requires you to create an IAM role with ReadOnlyAccess permissions.

L

LLM (Large Language Model) AI models used by AlertD to interpret results, generate insights, and provide recommendations in natural language.

M

Metric A quantitative measurement of resource behavior over time. CloudWatch metrics include CPU usage, disk I/O, network traffic, and more.

My Activity The sidebar section in AlertD that shows all your personal query sessions and chat history.

N

Namespace A container for CloudWatch metrics. AWS services publish metrics to specific namespaces (e.g., AWS/EC2, AWS/RDS).

P

Plan See Execution Plan.

R

ReadOnlyAccess An AWS managed IAM policy that grants read permissions across all AWS services without any write, modify, or delete capabilities. This is the policy AlertD requires.

Region A geographic area where AWS resources are hosted. Examples include us-east-1, eu-west-1, and ap-southeast-1.

S

Session A conversation thread in AlertD containing one or more queries and their results. Sessions appear in My Activity and Team Activity.

Specialist Agent An agent designed for a specific AWS service or task. Examples include EC2 Agent, S3 Agent, RDS Agent, and SqlAgent.

Statistic A mathematical aggregation of CloudWatch metric data over a period of time. Common statistics include Average, Sum, Minimum, Maximum, and SampleCount.

STS (Security Token Service) An AWS service that provides temporary, limited-privilege credentials for accessing AWS resources. AlertD uses STS tokens to assume your IAM role.

T

Tag A key-value label assigned to AWS resources for organization, cost allocation, and automation. AlertD can query resources by tags.

Team Activity The sidebar section showing queries and sessions from all members of your AlertD workspace.

Trust Policy An IAM policy that defines which principals (users, services, or accounts) are allowed to assume an IAM role. You configure a trust policy to allow AlertD to assume your role.

W

Workspace A shared environment in AlertD where team members with the same email domain collaborate. All users in a workspace can see each other’s sessions in Team Activity.
