Common Problems

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
