Discover the ServerSentinel Sensors
Sensors are monitoring elements that ServerSentinel uses to detect changes, events or certain signals sent by your IT system. ServerSentinel sensors measure available hard disk space, temperature in your server room, the CPU load etc. and respond accordingly.
Full variety of different sensors to choose from
ServerSentinel offers a wide, extensible array of configurable sensors. These sensors are grouped into the following categories.
Email Sensors
The IMAP Sensor checks the proper function of IMAP services, the SMTP Sensor checks if an SMTP service is available and works properly and the POP3 Sensor frequently checks a POP3 account.

Harddisk Sensors
With the help of the Directory Sensor you can monitor local as well as distant folders and their properties of a Windows or Linux system.
The Diskspace Sensor monitors the storage of drives on a Windows or Linux system.
The File Audit Sensor is able to monitor the security event log of local and remote computers to notify you when files or directories are accessed.
The File Sensor can monitor a single file on a Windows or Linux system.
The File System Sensor monitors changes to files or sub directories in a directory.
The S.M.A.R.T. Sensor monitors the status of local and remote hard drives.
Network/Internet Sensors
The DNS Sensor checks entries on a DNS server.
The FTP Sensor monitors files and directories on a FTP server.
The HTTP Sensor can monitor a specified website. It can be used to check the availability or the performance of the website.
The Hyper-V Sensor is a Type-1 Hypervisor that helps to monitor virtual systems and guarantees their availability.
The Ping-Sensor allows you to perform frequent echo pings.
The SNMP Request Sensor can query random network devices, supported by SNMP e.g. computers, printers, switches or systems for uninterruptible power supply.
The SNMP Trap Sensor can receive traps, sent from another network device over port 162. Traps are messages sent from many network devices to announce certain warnings or problems.
The Syslog Sensor can receive syslog messages, sent from the same or other network devices. Syslog messages are sent to announce certain warnings or problems or to log status reports, events or diagnostics.
The TCP Sensor checks the connection to a host on a specific port.
Operating System Sensors
The Performance Counter Sensor monitors performance qualities on the local system or a remote host with the Windows Performance Counter.
The Process Sensor allows you to monitor processes on a remote or local Windows or Linux system.
The Service Sensor allows to monitor a Windows service.
With the System Load Sensor the CPU, disk load and also the available memory of the local or a remote Windows or Linux system can be monitored.
The Windows Event Log Sensor is able to monitor event logs of local and remote computers and to notify you when new events occur.
The WMI Sensor performs custom WMI queries on the local or remote system.
USB-Sensors
The USB Temperature/Humidity Sensor can monitor the temperature (in °C) and the humidity (in relative humidity, RH) in a room.
The USB Contact Sensor monitors devices with a hardware sensor.
Misc Sensors
With the Database Sensor it is possible to connect to a database to frequently perform queries on a table or to execute a stored procedure.
The PowerShell Sensor allows you to execute a PowerShell script on a target host.
With the Script Sensor you can launch a process (EXE/BAT/PS1/VBS) and gather its output.
The SpeedFan Sensor can monitor the temperature of CPU cores, hard disks or fan speeds in conjunction with the free tool SpeedFan.
The SSH Sensor allows you to execute Bash scripts on an unix based target host via SSH.
The XML Sensor reads values from an XML file using XPath (XML Path Language).
