Why PRTG is the right tool for your agentless monitoring

 

PRTG agentless monitoring makes your IT infrastructure more reliable and your everyday work easier. 

 

 

 

 

 

 

 

 

 

 

Agentless monitoring saves you time and resources

Corporate IT infrastructures are becoming more and more complex. Numerous physical devices are now integrated into one or more networks, including servers, computers, routers, switches, ports, storage systems, IoT systems, and more.

When IT monitoring tools monitor systems directly, without any additional preparation (e.g., the installation of software agents), then this is referred to as “agentless monitoring.” This direct approach is particularly time-saving and efficient.

What is agentless monitoring?

With agentless monitoring, the performance values of a network system are recorded directly – in other words, without software agents being installed on the system. Instead, APIs (as interfaces) or protocols are used to record all relevant monitoring data.

What does a monitoring agent do?


Agent-based monitoring always requires an intermediary, or a so-called “agent” that is preinstalled by the manufacturer or IT administrator on the system whose performance is to be monitored.

This agent is usually a small piece of software that records then sends monitoring data to the IT monitoring tool. On the other hand, with agentless monitoring data is sent to the monitoring tool directly via built-in protocols or APIs.

3 good reasons to choose PRTG as your agentless monitoring tool

 

Paessler PRTG is an all-purpose agentless monitoring solution that combines the advantages of agentless monitoring with the benefits of agent-based monitoring.

Secure agentless monitoring – even in remote networks

Agentless monitoring is criticized as being unable to meet increasing security requirements and the needs of complex IT infrastructures that are often distributed across multiple locations. This is because agentless monitoring tools need remote access to monitor remote systems, which in turn can pose a security risk.

Not so with PRTG!

PRTG comes with remote probes that you can set up if your infrastructure consists of several distributed networks separated by firewalls from your local PRTG server. These probes monitor your system autonomously and transmit the collected data to the main PRTG server via TLS, providing you with a continuous, centralized overview of your entire monitoring environment.

Compatibility with protocols

In order to implement agentless monitoring, you need a monitoring tool that integrates as many native protocols as possible. PRTG does just that. It works with numerous protocols and technologies, including SNMP, WMI, HTTP/S, SSH, POP3, FTP, SMTP, NetFlow, sFlow, IP SLA, IPFIX, IPMI, Redfish, Modbus, MQTT, and many more. 

PRTG also comes with more than 250 preconfigured sensors for all the biggest manufacturers. For example, you can use PRTG SNMP sensors to monitor the system status of a Cisco device or Cisco UCS Blade Server, the hard disk of a Dell EqualLogic SAN storage system, or the free space of a logical hard disk.

Automated network discovery for quick setup

The PRTG Auto Discovery feature lets you set up your monitoring automatically after installation with just a few clicks. With this feature, PRTG automatically detects the subsystems and network devices in your IT infrastructure. The software uses preconfigured device templates to set up appropriate sensors so you can get started with your monitoring at once. The data from the detected devices is collected directly and displayed on easy-to-read dashboards.

PRTG also comes with custom sensors which allow you to personalize your monitoring as needed. With PRTG, you’ll never lose sight of your IT infrastructure and can prevent problems before they arise.

Agentless vs. agent-based monitoring

The advantages of agentless monitoring

Agentless monitoring requires little work and preparation. Thanks to its convenience, it is the most popular method for monitoring networks.

  • With agentless monitoring, there’s no need to install agents on the network objects to be monitored. As a result, the monitored devices remain unhindered and continue to perform well.
  • Agents must be updated regularly. Agentless monitoring eliminates this tedious task.

The advantages of agent-based monitoring

  • Agent-based monitoring often allows for the collection of more detailed data. This is due to the fact that some software and hardware providers offer agents that transmit more values to the IT monitoring tool.
  • By collecting the data themselves, agents reduce the load on the main server.

The disadvantages of agent-based monitoring

  • Installing software agents on multiple servers is time-consuming, especially in large IT environments. Agentless monitoring therefore comes with less administrative hassle.
  • Agents often require lots of CPU and memory and can significantly slow down the devices on which they are installed, and in some cases even bring them to a complete halt.
