  Nowadays, most systems and applications produce log records that are useful
for security and monitoring purposes such as debugging programming errors,
checking system status, and detecting configuration problems or even attacks.
To this end, a log repository becomes necessary whereby logs can be accessed
and visualized in a timely manner. This paper presents Loginson, a
high-performance log centralization system for large-scale log collection and
processing in large IT infrastructures. Besides log collection, Loginson
provides high-level analytics through a visual interface for the purpose of
troubleshooting critical incidents. We note that Loginson outperforms all of
the other log centralization solutions by taking full advantage of the vertical
scalability, and therefore decreasing Capital Expenditure (CAPEX) and Operating
Expense (OPEX) costs for deployment scenarios with a huge volume of log data.
