Systems and methods for detecting anomalies within a multi-tenant environment are described. Diagnostic tests are performed on one or more components, such as host computing devices. The one or more components send resulting diagnostic information to an electronic device such as a monitoring component that processes the diagnostic information. The electronic device determines whether one or more properties, such as errors, are comprised within the one or more components. Based at least in part on properties that may be found, a correlation may be made between at least two properties.
