If a load balancer or proxy is used between the Prometheus node and the RabbitMQ nodes it scrapes, the inactivity_timeout and idle_timeout values should be at least as large, and often greater than, the timeout and inactivity values used by the load balancer. Each microservice uses the most appropriate technique for horizontal scaling; most are stateless and can handle requests for any users while some (namely the ingesters) are semi-stateful and depend on consistent hashing. So generally I suggest setting query timeout way larger than --query. Try to increase the default value of the connection timeouts.

So they are. idle_timeout controls the window of time in which the client has to send more data (if any) within the context of an HTTP request. response-timeout=30s and you expect at max there will be 4 slow Thanos nodes, then you should set --query. Prometheus metrics libraries have become widely adopted, not only by Prometheus users, but by other monitoring systems including InfluxDB, OpenTSDB, Graphite, and Sysdig Monitor. have active alert from prometheus, but missing some alerts from alertmanager page: yongdao xuy: 8/22/19 3:34 AM: > we can see lot of active alerts on prometheus web, but can only query part of them on alert manager side. Recently I've come across an issue that took me a bit of time to figure out. QueryLogFile string `yaml:"query_log_file,omitempty"` // The labels to add to any timeseries that this Prometheus instance scrapes. Prometheus provides a functional query language called PromQL (Prometheus Query Language) that lets the user select and aggregate time series data in real time.
