PMM2-Agent Keeping PMM2-Server Config username & password in Plain Text

Percona Monitoring and Management (PMM) PMM 2.x
1

Hi Team,
Recently I’ve configured PMM2-Agent on one of my DB server to monitor it from PMM2-Server Dash board. During configuring my pmm2-agent I need to provide admin username & password of pmm2-server dashboard to register pmm2-agent. But PMM2-Agent keeping this username, password & server info in plain text. How can I get rid of pmm2-agent saving password in plain text ?

Is there any way to encrypt password in agent configuration file ?

This my Agent Config File:

[root@ config]# cat pmm-agent.yaml
# Updated by `pmm-agent setup`.

Hello Ferdous,
In the web documentation, there is a section on enabling both HTTP password protection and SSL encryption, which may help:

“Combining Security Features…You can enable both HTTP password protection and SSL encryption by combining the corresponding options” .It may be an alternative solution to the problem

Hello,
What you have shared is the documentation of Percona v1. What about v2? Also, why is pmm-agent.yaml showing password in the first place? Is there any way around to avoid it?

Hello Tayeen,
The link above is for both PMM1 & 2 (dropdown box) - this link takes you directly to PMM 2: Percona Monitoring and Management - sorry for any confusion…I believe it still works the same way in PMM2.x…can anyone confirm this?
