I am writing a prometheus.yml file to monitor multiple cassandra nodes. I grouped the nodes under 'titan' and 'cassandra_development'. Getting the below error while starting prometheus:

msg="Error loading config" err="couldn't load configuration (--config.file=prometheus.yml): yaml: line 5: mapping values are not allowed in this context"

I had this and I think it's your yaml. Run it through a yaml linter (such as http://yamllint.com ) and then fix any errors that it throws.

    Welcome to SO. It's a possibly useful answer, but more specific would be better. The questioner has provided his YAML, so can you check if it's valid? –  Apr 02 '18 at 17:05
