Any help or info will be appreciated...
Alert Logs are generated when Optimizer Rules are evaluated. By default, BMC TrueSight Capacity Optimization allows you to schedule the evaluation daily or weekly (see below).
You can add more option (e.g. an "Optimizer - Monthly") by adding a new Optimizer System Task. You can find more information at the following official BMC documentation page (Configuring the Optimizer task - Documentation for BMC TrueSight Capacity Optimization 11.5 - BMC Documentation ).
