Robust If This, Then That Platform
In it's simplest form, StackStorm is a robust engine for IFTTT operations, allowing you to set conditional logic for anything.
Advanced Event-Driven Automation
StackStorm also offers advanced automation, letting you create complex workflows to automate your world.
Sensors
Sensors are Python plugins for either inbound or outbound integration that receives or watches for events respectively. When an event from external systems occurs and is processed by a sensor, a StackStorm trigger will be emitted into the system.
Triggers
Triggers are StackStorm representations of external events. There are generic triggers (e.g. timers, webhooks) and integration triggers (e.g. Sensu alert, JIRA issue updated). A new trigger type can be defined by writing a sensor plugin.
Actions
Actions are StackStorm outbound integrations. There are generic actions (ssh, REST call), integrations (OpenStack, Docker, Puppet), or custom actions. Actions are either Python plugins, or any scripts, consumed into StackStorm by adding a few lines of metadata. Actions can be invoked directly by user via CLI or API, or used and called as part of rules and workflows.
Rules
Rules map triggers to actions (or to workflows), applying matching criteria and mapping trigger payload to action inputs.
Workflows
Workflows stitch actions together into “uber-actions”, defining the order, transition conditions, and passing the data. Most automations are more than one-step and thus need more than one action. Workflows, just like “atomic” actions, are available in the Action library, and can be invoked manually or triggered by rules.
Packs
Packs are the units of content deployment. They simplify the management and sharing of StackStorm pluggable content by grouping integrations (triggers and actions) and automations (rules and workflows). A growing number of packs are available on StackStorm Exchange. Users can create their own packs, share them on Github, or submit to the StackStorm Exchange.
Audits
Audit trail of action executions, manual or automated, is recorded and stored with full details of triggering context and execution results. It is also captured in audit logs for integrating with external logging and analytical tools: LogStash, Splunk, statsd, syslog.
