Agentless Overview

General Information

The Cloudamize Agentless Data Collector can be used to discover and assess physical and virtual machines without installing software agents on each machine throughout your infrastructure.

The collector is deployed on a physical Windows server or Windows virtual machine, and can be used to discover and assess both Windows and Linux machines. Each collector can be used to monitor up to 500 machines, and additional collectors can be installed on additional machines to handle larger infrastructures.

The Cloudamize Agentless Data Collector uses SSH to discover and communicate with Linux machines on the subnet, and WMI/RPC to discover and communicate with Windows machines. The collector then sends the TLS v1.2 encrypted data to the Cloudamize servers for processing.

 

Agent-Based VS Agentless

There are advantages and disadvantages to utilizing the Cloudamize Agentless Data Collector as opposed to installing software agents throughout the infrastructure. One obvious advantage will be in the case of high-security compliant infrastructures which are not permitted to install software and communicate out to remote servers from each machine in the infrastructure. The Cloudamize Agentless Data Collector can be installed on one machine in cases like this, and the entire infrastructure being assessed will send that data to this one machine over WMI (Windows) and SSH (Linux). All of this communication happens on the internal network and data will only leave the network from the machine with the collector installed.

The table below highlights the feature comparison between agent-based and agentless data collection.

Without having software agents installed on each machine, there are also disadvantages in a few areas. The following table shows a set of metrics and the impact that taking an agentless approach will have.

Metric

Impact

Short-lived connections

If a connection is short-lived it is not captured and that may result in missed inter-connectivity

Lower performance resolutions

Monitoring window is at every 5 min rather than every 30 seconds. Likely to miss short-term peaks

DNS traffic and analysis

Mapping between IP address and DNS is not available

SQL Editions Cost analysis will not include SQL editions and mapping

Performance Throttling

Agentless monitoring does not have performance controlling mechanism on the monitored host

.NET version

Limited ASR compatibility analysis
