SSH Named Profile

This profile monitors a UNIX Named Domain Name Server. DNS services are monitored remotely. Monitoring scripts are installed on the remote server and called from the GroundWork server using the SSH protocol. Please reference SSH document under GroundWork Profiles>SSH Profiles when using this profile.

Installation

GroundWork Monitor includes many monitoring profiles for a variety of devices, systems and applications. Profiles already imported on a new GroundWork installation include Service Ping, SNMP Network, and SSH UNIX. The GroundWork Monitor Configuration tool is used to import updated Profiles and Profiles that require additional setup; the Profile XML file and its companion Performance Configuration definition file. Services can also be imported in addition to Service Profiles in the Profile Importer. The import process is documented under GROUNDWORK PROFILES > How to import profiles.
