<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: System Status

On the System Status tab, you can view relevant system information. Furthermore, this page shows interesting usage statistics. Use the quick links for fast access to status information.

i_round_blueYou might need this data for debugging or when you contact the Paessler support team. They ask you in some cases to provide system status information to analyze any issues with PRTG.

i_round_blueThis documentation refers to an administrator that accesses the PRTG web interface on a master node. Other user accounts, interfaces, or failover nodes might not have all of the options in the way described here. In a cluster, note that failover nodes are read-only by default.

i_podIf 15 minutes (900) seconds have passed since your last credential-based login and you open a setup page from a different setup page, PRTG asks you to enter your credentials again for security reasons. A dialog box appears. Enter your Login Name and Password and click OK to continue.

Number of Sensors

Shows the number of sensors that you can use in PRTG. If you reach the limit, PRTG automatically sets each new sensor that you add to the Paused status.

Editions that allow an unlimited number of sensors do not restrict the number of possible sensors by license, so you can create sensors until you reach the performance limit. This means that you can use about 10,000 sensors per PRTG core server. However, this number depends on the performance of the PRTG core server system, and sensors and scanning intervals.

Description

Historic Data

Shows if PRTG is recalculating the historic data cache in the background. If so, you see the tasks to do until done. Usually, PRTG does this calculation after every PRTG core server restart.

Toplist Buffer

Shows the size of the Toplist buffer. When you use xFlow (NetFlow, jFlow, sFlow, IPFIX) or Packet Sniffer sensors, PRTG stores Toplist data. The data stream received is buffered and written to the data directory of the PRTG core server system.

i_round_blueDepending on the number and size of the data stream as well as the hard disk and system performance of the PRTG core server system, the buffer size can rise. When the buffer size reaches 500, PRTG drops Toplist data, which can lead to incorrect Toplist values for the sensors.
