Prometheus Node Exporter is an essential part of any Kubernetes cluster deployment. As an environment scales, accurately monitoring nodes with each cluster becomes important to avoid high CPU, memory usage, network traffic, and disk IOPS.Prometheus is typically used to collect numeric metrics from services that run 24/7 and allow metric data to be accessed via HTTP endpoints. This can be done manually or with various client libraries. Prometheus exposes data using a simple format, with a new line for each metric, separated with line feed characters.A collector is a part of an exporter that represents a set of metrics. It may be a single metric if it is part of direct instrumentation, or many metrics if it is pulling metrics from another system.
Do I need node exporter for Prometheus : The Node Exporter is an agent that gathers system metrics and exposes them in a format which can be ingested by Prometheus. The Node Exporter is a project that is maintained through the Prometheus project. This is a completely optional step and can be skipped if you do not wish to gather system metrics.
What is Prometheus metrics exporter
A Prometheus Exporter is a Pull Metric Exporter which reports metrics by responding to the Prometheus scraper requests. A Prometheus Exporter MUST support Pull mode. A Prometheus Exporter MUST NOT support Push mode. A Prometheus Exporter MUST only support Cumulative Temporality.
What does Prometheus Blackbox Exporter do : Prometheus Blackbox Exporter can probe external endpoints using protocols such as HTTP, HTTPS, ICMP, DNS, and TCP to collect metrics about their health and responsiveness. Prometheus can then use the metrics for alerting, graphing, and analysis.
When does it not fit Prometheus values reliability. You can always view what statistics are available about your system, even under failure conditions. If you need 100% accuracy, such as for per-request billing, Prometheus is not a good choice as the collected data will likely not be detailed and complete enough. To monitor services that don't use HTTP endpoints, such as hardware, you can use exporters. As an open-source tool, Prometheus has other major advantages—it's free, its code is available on GitHub, and its toolkit is readily customizable.
When not to use Prometheus
If you need 100% accuracy, such as for per-request billing, Prometheus is not a good choice as the collected data will likely not be detailed and complete enough.The combination of Prometheus and Grafana Agent gives you control over the metrics you want to report, where they come from, and where they're going.There are four primary Prometheus metric types PromQL can query: counters, gauges, histograms, and summaries. These metric types fulfill the needs or requirements for most use cases, and are found in Prometheus' official client libraries: Go, Java, Ruby, and Python. Metrics Exporter – Standard output
"Standard output" Metrics Exporter is a Push Metric Exporter which outputs the metrics to stdout/console. OpenTelemetry SDK authors MAY choose the best idiomatic name for their language. For example, ConsoleExporter, StdoutExporter, StreamExporter, etc.
What is the difference between OpenTelemetry and Prometheus exporter : OpenTelemetry offers a uniform approach for gathering, instrumenting, and exporting telemetry data. Prometheus, on the other hand, is distinguished by its proficiency in time-series data monitoring and its advanced alerting features.
How do I know if Prometheus exporter is running : To verify that node_exporter is running, open your browser and navigate to http://<IP of Node exporter host>:9100/metrics. All the metrics collected will be displayed; these are the same metrics Prometheus will scrape.
What are the disadvantages of Prometheus
The disadvantage is the vulnerability and limited scalability of these HTTP endpoints. In the design of Prometheus, the principle of simplicity has been emphasized and the system has been kept as simple as possible. For this reason, Prometheus is limited to one node. The overall design of Prometheus is really very nice.
Some of the metrics are missing in there.
initially, it is difficult to implement and needs practice to implement.
Its query language promQl is difficult at all.
Prometheus is punished for loving humankind. He stole fire to thwart Zeus' plans to eliminate humanity and create a new subordinate species. He is a benefactor who sacrifices himself for our good. His punishment is an indicator not of the dangers of fire but of the tyranny of Zeus.
Which is better Prometheus or Grafana : Visualization: Prometheus comes with a built-in visualization interface, but it is basic and primarily intended for ad-hoc querying. For a richer, more robust visualization experience, Prometheus recommends using Grafana.
