Monitor processes, folders, and files with prtg sensors on Windows Server 2019. Create sensors, view CPU usage and working set, and set limits for alerts.

Set up SharePoint monitoring in PRTG with WMI and Windows sensors to track CPU utilization, SQL queries, and key metrics, with alerts on thresholds.

Configure NetFlow on Cisco devices using a NetFlow configurator, enable read/write SNMP, and set up a PRTG NetFlow sensor to monitor top talkers, connections, and protocols.

Configure FortiGate NetFlow and monitor it with a PRTG NetFlow sensor, setting the collector IP, interfaces, and active flow timeout to reveal top talkers and protocols.

Explore how to monitor http transactions from across five continents using prtg cloud http v2, measuring get and post requests, time to first byte, load times, and availability.

Explore how PRTG handles device dependencies on a network map, simulate a switch failure, and observe how master sensor and device dependency govern alert propagation.

Create and customize PRTG maps with background images, icons, and sensors. Manage map access, drag-and-drop connections, and view change history.

Explore PRTG reports by viewing default summary reports for all sensors and exporting PDF or data files via email. Create device reports with tags and schedules, and manage group access.

Learn to configure a PRTG cluster with master and failover nodes for high-availability monitoring, while balancing sensor load and official sensor limits toward Windows server deployments.
