What can Prometheus monitor? Prometheus is a monitoring solution for recording and processing any purely numeric time-series. It gathers, organizes, and stores metrics along with unique identifiers and timestamps. Prometheus is open-source software that collects metrics from targets by “scraping” metrics HTTP endpoints.

What data does Prometheus collect? Prometheus collects metrics from targets by scraping metrics HTTP endpoints. Since Prometheus exposes data in the same manner about itself, it can also scrape and monitor its own health. For a complete specification of configuration options, see the configuration documentation.

What is Prometheus not good for? Prometheus’ primary focus is on reliability rather than accuracy. For this reason, it is ideal in highly dynamic systems such as microservices running in a cloud environment. It is probably not a good fit for a system that requires high accuracy, such as a billing application.

Can Prometheus monitor logs? You can configure the Logging operator to expose metrics endpoints for FluentD and Fluent-bit using ServiceMonitor resources. That way, a Prometheus operator running in the same cluster can automatically fetch your logging metrics.

What can Prometheus monitor? – Related Questions

Can Prometheus monitor services?

Monitoring with Prometheus is easy at first. You can have metrics and alerts in several services in no time. The problems start when you have to manage several clusters with hundreds of microservices running inside, and different development teams deploying at the same time.

Where is Prometheus data stored?

Prometheus stores its on-disk time series data under the directory specified by the flag storage.

What is Thanos Prometheus?

Thanos, simply put, is a “highly available Prometheus setup with long-term storage capabilities”. Thanos allows you to aggregate data from multiple Prometheus instances and query them, all from a single endpoint. Thanos also automatically deals with duplicate metrics that may arise from multiple Prometheus instances.

Is Prometheus reliable?

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.

What is the difference between Prometheus and Grafana?

Grafana and Prometheus, both help us in tackling issues related to complex data in a simplified manner. Grafana is an open-source visualization software, which helps the users to understand the complex data with the help of data metrics. Prometheus is an open-source event monitoring and alerting tool.

What is Prometheus Pushgateway?

The Prometheus Pushgateway allows you to push time series from short-lived service-level batch jobs to an intermediary job which Prometheus can scrape. Combined with Prometheus’s simple text-based exposition format, this makes it easy to instrument even shell scripts without a client library.

How do I know if Prometheus is working?

To verify that node_exporter is running, open your browser and navigate to http://:9100/metrics. All the metrics collected will be displayed; these are the same metrics Prometheus will scrape.

How do I check my Prometheus service status?

Open the browser and access to server’s IP with port 9090 to access the web interface of Prometheus. Go to Status>>Targets to see what all and where Prometheus is currently running.

Who owns Prometheus?

SAN FRANCISCO, /PRNewswire/ — Genstar Capital, a leading private equity firm focused on investments in targeted segments of the software, industrial technology, healthcare, and financial services industries, announced today the acquisition of Prometheus Group from Francisco Partners for over $1 billion.

Is Prometheus in memory?

The answer is no, Prometheus has been pretty heavily optimised by now and uses only as much RAM as it needs. If there was a way to reduce memory usage that made sense in performance terms we would, as we have many times in the past, make things work that way rather than gate it behind a setting.

How does Prometheus retention work?

The data outside the retention is automatically deleted. By default the retention is configured to 15 days. The amounts of data stored on disk depends on retention — higher retention means more data on disk. The lowest supported retention in Prometheus is 2 hours (2h).

Is Prometheus push or pull?

Prometheus by design implements a pull-based approach for collecting metrics. For most of us, this is a departure from the push-based monitoring systems we’ve been using for the past decade.

How do you scale Prometheus?

Prometheus at Scale with Federation

The most straightforward way to scale Prometheus is by using federation. Simply put, federation is the ability of one Prometheus server to scrape time-series data from another Prometheus server. Prometheus offers two types of federation: hierarchical and cross-service.

How do I get Prometheus High Availability?

For high availability of the Alertmanager, you can run multiple instances in a Mesh cluster and configure the Prometheus servers to send notifications to each of them.

Why is Prometheus better than Zabbix?

Both Prometheus and Zabbix are great tools for monitoring time-series, where Zabbix is the older-generation tool and Prometheus is cutting edge. Both tools are open source with hosted options available. You can use Hosted Prometheus with minimal configuration to gain in-depth insight into your environments.

What is advantage of Prometheus?

Prometheus offers a much richer query language, can handle higher cardinality metrics, and forms part of a complete monitoring system. If you’re already running Hadoop and value long term storage over these benefits, OpenTSDB is a good choice.

Why is Prometheus so popular?

Prometheus is an open-source monitoring software that is very popular in the industry. Prometheus is easy to customize, and produces metrics without impacting application performance. Along with this, Prometheus monitoring can be used to provide clarity into systems and how to run them.

Which is better Prometheus or Grafana?

Conclusion. Both Prometheus and Grafana are built around time-series data – with Prometheus primarily on the gathering side and Grafana on the reporting side. Both tools are open-source, are widely available with lots of community support, and are more than capable of meeting the needs of enterprises, large and small.

How does Prometheus and Grafana work together?

Prometheus acts as the storage backend and open source grafana as the interface for analysis and visualization. Prometheus collects metrics from monitored targets by scraping metrics from HTTP endpoints on these targets. Conveniently, Prometheus exposes a wide variety of metrics that can be easily monitored.

Can I push data to Prometheus?

As you may be aware that prometheus is a pull based metrics server which scraps data from the specified scrap endpoints. But we can also push data to Prometheus using PushGateway.

What is job in Prometheus?

In Prometheus terms, an endpoint you can scrape is called an instance, usually corresponding to a single process. A collection of instances with the same purpose, a process replicated for scalability or reliability for example, is called a job.
