Installing and Configuring SigNoz Agent on Ubuntu 20.04

Happy

Kind of dumb question, but how do you install agents on machines that you want to monitor, and send data to Signoz installation? Or do I just need to install prometheus agent?

Srikanth

Run signoz collector either as binary or docker on the machine . Use `hostmetrics` receiver.

Happy

"" doesn't install using apt

Happy

"make" on source fails with "cannot load crypto/ecdh: malformed module path "crypto/ecdh": missing dot in first path element"

Happy

NVM, you said binary. My bad.

Happy

Srikanth Man, you guys really need to have atleast hostmetrics end to end setup guide. Now the binary doesn't start, and my guess would be it needs a config file. I am trying to run this as binary file using ./signoz-collector_0.76.2_linux_amd64 Can I have a sample resource file to go with it, and where to put it? Same folder as binary? Does this collector works as Prometheus (pull model) or DataDog Agent (push model)? If it's a pull model do I need to configure the Signoz Host to pull from this collector? Or if it's a push model, this collector will automatically start sending metrics to Host after config is provided?

Srikanth

hostmetrics is enabled by default.

Srikanth

Srikanth

It’s a push model and you need to use the otlp exporter to send data.

Happy

Fantastic. Can you now help me please with where to put that config file?

Happy

Ok the binary still fails with same error as above after providing the file. Running it on Ubuntu 20.04 using "./signoz-collector_0.76.2_linux_amd64"

Srikanth

Ah, that’s a bummer. Can you create an issue here

Prashant

Happy not able to reproduce the issue in Ubuntu 20.04. could you please verify that architecture of the machine? Is it amd64? If possible, share output of `uname -a` .
