1. A computer-implemented method for monitoring transaction processing at a computing system comprising: monitoring transactions between computing resources of a computing system using a transaction monitoring agent wherein access to the computing resources is obtained via a communication network; generating, by the transaction monitoring agent, transaction log information corresponding to the transactions; obtaining, automatically by a computing device, a current transaction rate for a current time period based on the transaction log information; obtaining, automatically by the computing device, a previous transaction rate for a previous time period prior to the current time period based on the transaction log information; comparing, by the computing device, the current transaction rate to the previous transaction rate; generating, by the computing device, a transaction rate alert responsive to determining that the previous transaction rate exceeds the current transaction rate by greater than a first predetermined transaction rate difference threshold used to trigger alerts; determining, by the computing device, that a network latency on the communication network has increased; adjusting the first predetermined transaction rate difference threshold used to trigger alerts to a second, different predetermined transaction rate difference threshold used to trigger alerts automatically by the computing device in response to the determining that the network latency has increased; determining, by the computing device, that the network latency on the communication network has decreased; and reverting the second predetermined transaction rate difference threshold used to trigger alerts to the first predetermined transaction rate threshold used to trigger alerts automatically by the computing device in response to the determining that the network latency has decreased.
