; CheckDisk - CheckDisk can check various file and disk related things. The current version has commands to check Size of hard drives and directories.
CheckDisk = 1


; Event log Checker. - Check for errors and warnings in the event log. This is only supported through NRPE so if you plan to use only NSClient this wont help you at all.

; Check External Scripts - A simple wrapper to run external scripts and batch files.
CheckExternalScripts = 1


; Helper function - Various helper function to extend other checks. This is also only supported through NRPE.
CheckHelpers = 1

CheckNSCP = 1


; CheckSystem - Various system related checks, such as CPU load, process state, service state memory usage and PDH counters.
CheckSystem = 1


; CheckWMI - CheckWMI can check various file and disk related things. The current version has commands to check Size of hard drives and directories.

; NRPE server - A simple server that listens for incoming NRPE connection and handles them.
NRPEServer = 1


; NSCAClient - Passive check support over NSCA.
NSCAClient = 1


; NSClient server - A simple server that listens for incoming NSClient (check_nt) connection and handles them. Although NRPE is the preferred method NSClient is fully supported and can be used for simplicity or for compatibility.
