In GroundWork Monitor you may want to delete a host configuration, delete multiple host configurations, remove Cloud Hub or Cacti associated hosts or remove hosts from the performance screen. Each of these procedures are outlined below.
Perform the steps below to remove a single host configuration.
There is an easy way to delete one, many, or all hosts. The Delete hosts tool completely removes a host, its associated services, and any reference such a a membership in host groups, service groups, groups, and profiles.
|If you select the " * " filter to list all hosts and select Check All to remove all hosts, the system will consider this action as an invalid configuration with no hosts and services. This should be avoided.|
|Like all configuration changes, you will need to perform a Commit operation (Configuration > Control > Commit), to complete the task of removing a host.|
GroundWork Hub instances are the hosts that have been setup using the GroundWork Cloud Hub monitoring subsystem. Cloud Hub configuration, using hypervisors and or virtualization manager(s), performs various functions including auto discovery, creating of hosts and host groups, and applying of profiles. Completely removing previously set environments in Cloud Hub includes a command line entry, which is outlined below.
If you decide you do not want to monitor a particular region but you want to keep the configuration, simply navigate to GroundWork Administration > GroundWork Cloud Hub and select STOP for the corresponding connection. The connection, as previously configured, can be started again by selecting START.
To completely DELETE a specific region's monitored hosts follow the steps below. All of the created host groups and the discovered and monitored instances for that region will be deleted from the Foundation database within a few minutes and monitoring access to the region endpoint will cease.
For most SNMP monitoring, Cacti provides a simpler way to discover and configure monitoring of network devices. The data collected by Cacti is displayed through the Cacti UI as graphs and the graph data is also displayed in the GroundWork Status application. If Thresholds are set in Cacti for a device being monitored, that device and any checks performed on it will be automatically added to GroundWork Monitor. The addition is made to the Foundation database bypassing Nagios, additionally the triggering of the threshold will create an alarm message to be sent via the NoMa application. To properly remove Cacti associated hosts you must remove the Threshold first as outline below.
Following is a simple procedure to remove hosts from the performance screen.
