Detection of outages ( server down ) runs on the basis of an ongoing online communication between the CM Server and C-Monitor client. The C-Monitor client contacts the CM Server every 15 to 30 seconds (the interval depends on license and the current setting of the CM server) and if this connection isn´t accomplished, interval for notification of outage is being counted.
Minimal outage times for notification according to the type of C-Monitor client license:
Premium (Server/Workstation) 1 min
Standard (Workstation) 1 min
BASIC (Server/Workstation) 15min
This applies for all supported operating systems: MS Windows, Linux/FreeBSD, (Mac) OS X.
