13. The apparatus of claim 11 , wherein the program code comprises program code executable by the processor to cause the apparatus to: associate two or more of the generated digital fingerprints within a fault event set in response, at least in part, to, determining a correspondence among the two or more generated digital fingerprints based, at least in part, on the identities of the two or more nodes; and for each of the two or more generated digital fingerprints, determining a pattern matching correlation between the generated digital fingerprint and the classifier digital fingerprints; and determining a pattern matching correlation between the generated digital fingerprint and the other of the at least two generated digital fingerprints.
11. An apparatus comprising: a processor; and a machine-readable medium having program code executable by the processor to cause the apparatus to: generate, by a fingerprint generator, multiple classifier digital fingerprints, wherein each of the classifier digital fingerprints comprises a bit sequence, recorded in association with a respective result classifier; generate, by a transaction processor, transaction event entries from network messages between nodes, wherein the transaction event entries contain message text associated with a transaction between two or more nodes; generate, by the fingerprint generator, a digital fingerprint, from each of the transaction event entries, wherein each of the generated digital fingerprints comprises a bit sequence that is associated with an identity of at least one of the two or more nodes, and wherein said generating a digital fingerprint includes, for each bit position in the bit sequence, determine whether the message text includes a specified text pattern; and set the bit position value based on the determination of whether the message text includes the specified text pattern; and for each of the generated digital fingerprints, group the generated digital fingerprint into one or more event classification sets that each correspond to one of the result classifiers based, at least in part, on pattern matching the generated digital fingerprint with the classifier digital fingerprints, wherein the one or more event classification sets includes a fault classification set; determine a prospective fault condition for one of the two or more nodes based on the fault classification set; in response to determining the fault condition, reading a profile data record that associates the identity of one of the two of more nodes with service domain data; determine a service domain impact scope based on, the service domain data and transaction data contained in transaction event entries corresponding to the digital fingerprints grouped in the fault classification set; and issue an alert to at least one of the two or more nodes based, at least in part, on the service domain impact scope.
