## Correlation

Moogsoft AIOps uses to group similar items, such as alerts and Situations, together. It also correlates Situations with external systems to maintain the bidirectionality between a Situation and an external system, such as a ticketing integration, by storing the corresponding ID of a related incident.

Examples of correlation in Moogsoft AIOps include:

• Cookbook : Clusters alerts into Situations by c orrelating them based on similarities in certain characteristics such as their description, host or location.
• Graze API : Endpoints  addSigCorrelationInfo  ,  getSigCorrelationInfo  , and  removeSigCorrelationInfo  allow you to add, retrieve or remove the external systems associated with a Situation.
