You can use log data to increase your administration capabilities and finish jobs that would otherwise be tough or require more complex solutions. Performance monitoring is the most typical usage of log parsing tools, but they can also be used for a variety of other remedial and monitoring activities.

Here is our list of the best Syslog and Log viewers:

  1. SolarWinds Kiwi Syslog Server – FREE TRIAL Outstanding centralized syslog server solution that includes a variety of features that can enhance your mitigation, performance, error, and security detection, among other use cases.
  2. ManageEngine EventLog Analyzer – FREE TRIAL Hardware and application log monitoring were merged into one unified system with an enterprise-level log parsing and analysis solution.
