There are a few basic concepts that are important to understand before you continue to use this guide:
EventSentry uses agents to monitor your servers and workstations. The EventSentry agent needs to be running on a machine in order for it to be monitored. The agents can either send data for select action types through the collector, or alternatively perform all notifications themselves directly, e.g. sending an email, writing to a database, etc..
You can easily install, uninstall and update agents using the "Remote Update" feature of EventSentry.
2. Remote Update
The Remote Update feature allows you to initially install the EventSentry agent on remote computers, push the latest configuration changes, update agents and stop/start the EventSentry agent on or more remote computers.
Remote Update works using SMB and RPC to connect to the remote computers, just like you would with applications like regedit and when accessing remote shares. As such, you will need to be able to access the registry and shares on the remote computer in order to use remote update. These services are available by default.
3. Heartbeat Monitoring
Heartbeat monitoring can monitor the uptime of remote computers using ping/icmp, can check remote TCP ports, monitor the state of the EventSentry service and retrieve system metrics via SNMP. The heartbeat feature does not require an agent on the remote computers and relies on the "EventSentry Heartbeat Agent" to be running on at least one computer in your network.
