These metrics are aggregated on a ten Otherwise, the interval can be assumed to be 10 seconds Finally, Consul can be configured to send telemetry data to a remote monitoring system. However, this configuration didn’t cater to exporters like the snmp_exporter or blackbox_exporter. The Consul agent collects various runtime metrics about the performance of different libraries and subsystems. Prometheus adopt a pull based model in getting metrics data by querying each targets defined in its configuration. collect metrics from a Nomad cluster. However, this configuration didn’t cater to exporters like the snmp_exporter or blackbox_exporter. I’ve gained huge insights into my home network (and a few external services I rely on), and have been very happy with it. The default for MaxAge in Prometheus is 10m, but for reasons not clear to me, in the go-metrics library used in Consul (that wraps the Prometheus client library), it's 10s:This means that you'd better use a scrape interval of 10s or less if you want to be able to capture quantile timings.Successfully merging a pull request may close this issue. Thus we can monitor our services end to end, by using prometheus. In a previous post I covered how to use Consul for service discovery of standard exporters, allowing Prometheus to automatically discover what services to monitor. Gauges is a list of gauges which store one value that is updated as time goes on, such as the amount of memory allocated. Adding new endpoints has been pretty straightforward. The Consul agent collects various runtime metrics about the performance of We already configured the Consul Servers to send metrics to a statsd server, so we only have to make sure we start one on each host running Consul Server.Before we start an statsd-exporter, we first have to do some configuration first. These metrics are aggregated on a ten second interval and are retained for one minute. Let’s assume that there is a “node-exporter” service as in our example, this service can includes hundreds of instances from different teams. overview of both number of open connections and bytes sent and received between Once we have configured this on all the Consul Servers, we need to restart them one by one so we keep the Consul Cluster running.When you use Prometheus, you’ll use exporters for your applications or databases to expose the metrics for Prometheus. Points is a list of point metrics, which each store a series of points under a given name. You can see some more information about configuring Consul for Telemetry on this page The IP Address is from the host itself, and in this case we have to send it to port 9125. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.By clicking “Sign up for GitHub”, you agree to our The actual values show up there for ~10 seconds and then switch to NaN.This appears to be the normal behaviour for summaries in Prometheus: the sum and count are eternal, but the quantiles expire and afterwards only contain NaN. When you have a tool like Zabbix or Nagios, you’ll need to write one or multiple scripts to gather all metrics and see how much you can store in your database without loosing performance of your monitoring tool. This blogpost was before Consul made the new endpoint available for metrics, but this exporter is way easier to use!Fill in your details below or click an icon to log in:Monitoring Consul with statsd exporter and Prometheus We need to make sure we have a statd mapper file. When you look for monitoring Consul in google, you’ll find a lot of pages that shows you that you can use Consul as a monitoring tool but not many on how you can monitor Consul itself. As a result, with this structure, Prometheus can discover a service that we will create on the Consul and

One port on which the statsd is available for retrieving performance metrics (9125) and the other port (9102) is used for Prometheus to scrape these metrics.At this moment, I have added the following into the Prometheus configuration to let Prometheus scrape the statsd-exporter metrics:This works for now because I Ansible to generate a Prometheus configuration, but I’ll go probably using a consul_sd_config in the near future so I won’t have to add all kinds of static configuration.Once we have restarted Prometheus and started the statsd-exporter containers, I can see the following metrics appear in Prometheus:(And much more, but the above 3 are examples which are used as an explanation in the previous paragraphs.
