When I try to add a datasource in Grafana, I get: "HTTP Error 502: Bad Gateway, please check the datasource and pmproxy settings. To use this data source, please configure the URL in the query editor."
- check if pmproxy is running:
systemctl status pmproxy - make sure that pmproxy was built with time-series (libuv) support enabled. You can find out if so in $PCP_LOG_DIR/pmproxy/pmproxy.log
