					<description><![CDATA[How would you check that a HTTP endpoint is returning a 204? We've previously looked at using the blackbox exporter to check that a 2xx response code is being returned, you might however consider only particular 2xx codes as okay. Your first thought might be to use an alert based on the probe_http_status_code metric, however [&#8230;]]]></description>

					<description><![CDATA[We've previously looked at scraping services from consul and ssh checks. How can we combine those? The use of relabelling for the blackbox exporter isn't tied to static_configs, you can use it with any service discovery mechanism. I'll presume you already have a working Consul setup. To demonstrate first we run the blackbox exporter: wget [&#8230;]]]></description>

					<description><![CDATA[Among the Blackbox exporter's probe types is DNS. As with other probe types, DNS probes are intended to be used to run one query against many different DNS servers by Prometheus, and verify that the DNS servers are working. Let's try it out by checking if DNS servers are returning that robustperception.io is using Google [&#8230;]]]></description>

					<description><![CDATA[Ever wanted more information about Blackbox probe failures? There are three different ways to get debugging information from the Blackbox exporter. The first is to add &#38;debug=true to the probe URL, for example :9115/probe?module=http_2xx&#38;target=https://www.prometheus.io/&#38;debug=true. This will not produce metrics, but rather detailed debug information: There's three parts. The first are the logs, the second are the metrics, [&#8230;]]]></description>

					<description><![CDATA[It's easy to check if HTTP and HTTPS endpoints are working with the Blackbox Exporter. The Blackbox exporter supports several different types of probes, which includes HTTP. To demonstrate this let's start by downloading and running the blackbox exporter: wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.12.0/blackbox_exporter-0.12.0.linux-amd64.tar.gz tar -xzf blackbox_exporter-*.linux-amd64.tar.gz cd blackbox_exporter-* ./blackbox_exporter How the Blackbox exporter works is that the [&#8230;]]]></description>

					<description><![CDATA[The Blackbox exporter can perform ICMP probes. Let's see how. First download and run the blackbox_exporter: wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.12.0/blackbox_exporter-0.12.0.linux-amd64.tar.gz tar -xzf blackbox_exporter-*.linux-amd64.tar.gz cd blackbox_exporter-* sudo ./blackbox_exporter sudo is used here as ICMP typically requires raw socket access, and running as root is one way to provide the necessary privileges. If you visit :9115/probe?module=icmp&#38;target= the probe will be performed, [&#8230;]]]></description>

Previously, timeouts for probes would be set individually via configuration of the Blackbox exporter itself. Now the timeout for probes may be set [&#8230;]]]></description>
