Causal Entity Graph

The causal entity graph is a continuously updated model of every entity in your environment — services, hosts, pods, databases, cloud resources — and the causal relationships between them. It is the foundation ArcIn reasons over.

What is an entity#

An entity is anything Applicare monitors: a service, host, container, database, queue, cloud resource, or third-party dependency. Entities are discovered automatically from traces, agents, and cloud APIs — you don't declare them.

Causal vs. correlational edges#

Edges capture direction of dependency (A calls B, B runs on host C). Because the graph knows direction, ArcIn can distinguish a cause from a coincidence: a symptom downstream can't be the cause of an anomaly upstream. This is what keeps root-cause results precise.

Exploring the graph#

Open any entity to see its neighbours, current health, and blast radius — the set of entities that would be affected if it fails. During an incident the graph highlights the propagation path from cause to symptom, which you can replay over time.
