This article applies to:
• Onboarding/Usage Monitoring/
• Product edition: All versions
• Feature Category: Proxy and Telegraf.
Overview:
While It is clear what are main functions of the Proxies and the Telegraf agents, it is important to have in mind/ present their main differences, how do they relate one another and their role within the VMware Aria Operations for Applications environment
Procedure : The following article aims to accomplish the above intention by offering a comparison chart between the Proxy and the Telegraf agent .

Telegraf Agent |
|
Both main services' goal is to gather data metrics from different data sources to later ingested into VMware Aria Operations for Applications. |
|
|
Requires to run on host separated from data sources. By default, the proxy runs on dedicated host. |
As it is a light-weight server process, it can run on same or different host as where the data sources are. Usually, the Telegraf runs on same host as from data sources. |
|
The collected data is sent directly to VMware Aria Operations for Applications. |
It can send data directly to VMware Aria Operations for Applications, but usually is configured to send the gathered data to the Proxy first. |
|
It can buffer into disk significant amount of data in the event of interruption on the communication towards VMware Aria Operations for Applications to send it once the communication is restored. |
The Telegraf cannot buffer into disk data to be sent later on. Because of it, it is configured to rely on the Proxy for this feature. |
|
Both services can be installed and operate on different platforms including: Windows, MacOS, different Linux's distros, and even Docker and Kubernetes. |
|
|
Both generates and sends metrics of their own for health and monitoring purposes. |
|
|
The Proxy accepts metrics from a multiple variety of collector agents. |
It usually gathers metrics from the data sources located on the same host as where the Telegraf resides. |
|
While both Proxy and Telegraf can be tunable and can be adjusted, the Proxy has significantly richer properties and features. |
|
|
The proxy can work with other proxies in different fashions : Team of Proxies behind load balancers, Proxy chaining - Proxy relying its data to another proxy -. |
The Telegraf usually sends collected data to a Proxy or directly to VMware Aria Operations for Applications, but it does not work with other Telegraf agents. |
