Overview

The Trendics Remote Agent allows Pushing Performance Data to Trendics where the data is stored, crunched, trended, and alerted upon as needed.

• Linux Plug-In
  • Available Disk Space
  • Free Memory
  • Swap Usage
  • Number of Running Processes
• MySQL Plug-In
  • Inserts/Second
  • Updates/Second
  • Deletes/Second
  • Disk Read Bytes/Second
  • Disk Write Bytes/Second
