Prometheus is a free software application used for event monitoring and alerting. It records real-time metrics in a time series database (allowing for high dimensionality) built using a HTTP pull model, with flexible queries and real-time alerting.
What is Grafana and Prometheus?
Prometheus is a monitoring solution for storing time series data like metrics. Grafana allows to visualize the data stored in Prometheus (and other sources). This sample demonstrates how to capture NServiceBus metrics, storing these in Prometheus and visualizing these metrics using Grafana.

What is Grafana used for?
Grafana is a free and open source (FOSS/OSS) visualization tool that can be used on top of a variety of different data stores but is most commonly used together with Graphite, InfluxDB, Prometheus, and Elasticsearch.
Can we use Grafana without Prometheus?
Grafana can only use data from external systems like Prometheus, MySQL, Azure Monitor and Amazon CloudWatch. That means Grafana has no means to collect data on its own, through agents or other data pipelines, and is thus dependent on other systems to provide data. Limited data type visualizations.
What is node exporter?
Node Exporter is a Prometheus exporter for server level and OS level metrics with configurable metric collectors. It helps us in measuring various server resources such as RAM, disk space, and CPU utilization.
Which is better Prometheus or Grafana?
Prometheus & Grafana: Better Together
Prometheus collects rich metrics and provides a powerful querying language; Grafana transforms metrics into meaningful visualizations. Both are compatible with many, if not most, data source types. In fact, it is very common for DevOps teams to run Grafana on top of Prometheus.
How much does Prometheus cost?
Prometheus is a free tool, though many companies provide Prometheus as a service covering, hosted Prometheus, Graphite, and Grafana. Whereas, Datadog charges a minimum of $15 per month for one host and other services, including log management and APM.
Does Prometheus run on Windows?
The Prometheus server is a single binary called prometheus (or prometheus.exe on Microsoft Windows). We can run the binary and see help on its options by passing the –help flag.
What are exporters in Prometheus?
A Prometheus Exporter is a piece of software that. Can fetch statistics from another, non-Prometheus system. Can turn those statistics into Prometheus metrics, using a client library. Starts a web server that exposes a /metrics URL, and have that URL display the system metrics.
Who rescued Prometheus?
For his crimes, Prometheus was punished by Zeus, who bound him with chains and sent an eagle to eat Prometheus’ immortal liver every day, which then grew back every night. Years later, the Greek hero Heracles, with Zeus’ permission, killed the eagle and freed Prometheus from this torment (521–529).

Zeus was outraged by Prometheus’ theft of fire and so gave the Titan an eternal punishment by having him taken far to the east, perhaps the Caucasus. Here Prometheus was chained to a rock (or pillar) and Zeus sent an eagle to eat the Titan’s immortal liver.
Is Grafana free to use?
A forever free plan
The new Grafana Cloud free plan is a composable observability solution, with metrics and logs integrated within Grafana, and it’s managed by us completely for free.
What is Prometheus alerting?
Alerting with Prometheus is separated into two parts. Alerting rules in Prometheus servers send alerts to an Alertmanager. The Alertmanager then manages those alerts, including silencing, inhibition, aggregation and sending out notifications via methods such as email, on-call notification systems, and chat platforms.
Where is the Prometheus data stored?
Disk usage
Prometheus stores its on-disk time series data under the directory specified by the flag storage. local. path . The default path is ./data (relative to the working directory), which is good to try something out quickly but most likely not what you want for actual operations.
