Sensu Windows client not seeing config.yml

Sensu Go
1

I cannot get Windows to find my backend server. The windows client refuses to use the agent.yml configuration file. I have my configuration file in c:\programdata\sensu\config\agent.yml as documentation suggests.

I then use sensu-agent service install.
When the service starts i look in the log file configured at c:\programdata\sensu\log\agent.log and it is trying to connect to 127.0.0.1.

This is a vm running on Windows Server 2019. This was built from source code at https://github.com/sensu/sensu-go

Versions are:

sensu-agent version (devel)+ce, community edition, built with go1.15.2
sensu-backend version (devel)+ce, community edition, built with go1.14.6

They both used the same v. 6.0.0 tagged source code.

My configuration is:

Hey,
Did you make the change to the configuration file after starting the Sensu Agent service? You might need to stop and restart the service to ensure your changes are picked up. The configuration file is only read once at beginning of service start.

I have recreated the service multiple times. Stopped and started it. Is there something that needs to be deleted after the service restarts or anything?

I found out what was wrong. There should be something that says why the config file isnt valid. It turned out to be this line:

trusted-ca-file: “c:\opt\sensu-go\ssl\ca.pem”

It should be escaped…

trusted-ca-file: “c:\opt\sensu-go\ssl\ca.pem”
