When creating new sensors you will see the following groups of sensor types. Note that some sensor types will show up several times in this list because they fit into more than one category:
- Common Sensors: The most common sensor types for network monitoring.
- Bandwidth Monitoring: Monitoring of bandwidth usage using WMI, SNMP, Packet Sniffer or xFlow (NetFlow/sFlow).
- Web Servers (HTTP, HTTPS): Sensors based on the HTTP protocol.
- SNMP: Sensors based on the Simple Network Management Protocol (SNMP).
- Windows Systems (WMI): Monitoring of Windows systems through Windows Management Instrumentation (WMI).
- Various Protocols: Various sensor types for services used on the Internet and others (PING, PORT, FTP, DNS, RDP, HDD Health etc.).
- Mail Servers: Sensors for mail servers (SMTP, POP3, IMAP, SMTP&IMAP Round Trip, SMTP&POP3 Round Trip etc.).
- SQL Servers: Monitoring of SQL Servers (MySQL, MS-SQL and Oracle).
- File Servers: Monitoring of File Servers, NASs, etc.
- Virtual Servers: Sensors for VMware Servers, Hyper-V and Amazon CloudWatch.
- VoIP and QoS: Quality-of-service monitoring and Cisco IP SLA monitoring via SNMP.
- Custom Sensors: Various sensor types that enable you to define your own sensor scripts, including Sensor Factory Sensor Type for combination of measurement results. In this group, you'll find a user definable version of some sensors from other groups.
In the following sections, the most important sensors will be described.
