You didn't say what URL you put in for the data source. But based on the error, I'm guessing that you've pointed the URL at an instance of node_exporter, not an instance of prometheus.
That is, I think you put: http://127.0.0.1:9100 # the port which node_exporter listens on If so, you should have put: http://127.0.0.1:9090 # the port which prometheus listens on On Tuesday, 15 November 2022 at 06:59:11 UTC [email protected] wrote: > i need support install data sources error "Error reading Prometheus: > bad_response: readObjectStart: expect { or n, but found <, error found in > #1 byte of ...|<html> <|..., bigger context ...|<html> <head><title>Node > Exporter</title></head>|..." > -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
