I am trying to add a new Prometheus source. I can curl the address and see data:
# HELP process_virtual_memory_bytes Virtual memory size in bytes.
# TYPE process_virtual_memory_bytes gauge
process_virtual_memory_bytes 188379136.0
# HELP process_resident_memory_bytes Resident memory size in bytes.
# TYPE process_resident_memory_bytes gauge
process_resident_memory_bytes 40480768.0
# HELP process_start_time_seconds Start time of the process since unix epoch in seconds.
# TYPE process_start_time_seconds gauge
process_start_time_seconds 1538041555.58
# HELP process_cpu_seconds_total Total user and system CPU time spent in seconds.
# TYPE process_cpu_seconds_total counter
process_cpu_seconds_total 180.51
# HELP process_open_fds Number of open file descriptors.
# TYPE process_open_fds gauge
process_open_fds 16.0
# HELP process_max_fds Maximum number of open file descriptors.
# TYPE process_max_fds gauge
process_max_fds 1048576.0
# HELP python_info Python platform information
# TYPE python_info gauge
python_info{implementation="CPython",major="3",minor="7",patchlevel="0",version="3.7.0"} 1.0
# HELP active_feed_clients Number of active users per feed
# TYPE active_feed_clients gauge
But, when I click Save & Test, I get an error box with no details:
I am not sure what I am doing wrong.
If it makes any difference, the service that is reporting the data is inside a Kubernetes pod. But, From the Grafana server, I can make curl requests so it should have no problem seeing it.
Thanks for any help you can offer.
