Monitor Armory Enterprise with Prometheus (2023)

FAQs

What can I monitor with Prometheus? ›

Prometheus is an open-source technology designed to provide monitoring and alerting functionality for cloud-native environments, including Kubernetes. It can collect and store metrics as time-series data, recording information with a timestamp. It can also collect and record labels, which are optional key-value pairs.

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. In such a case you would be best off using some other system to collect and analyze the data for billing, and Prometheus for the rest of your monitoring.

Configuring Prometheus to monitor itself

Since Prometheus exposes data in the same manner about itself, it can also scrape and monitor its own health.

A very good tool for continuous monitoring.

Best cloud native and metrics-based tool support, the best monitoring tool that I have been using for months and continuing. Prometheus can also be combined with Grafana to expose a nice counter and use Alertmanager to produce complicated alert rules.

Prometheus can handle millions of time series. However, with the above mentioned default setting for storage. local. target-heap-size , you will be limited to about 200,000 time series simultaneously present in memory.

Prometheus solves the problem of how devs can monitor highly dynamic container environments. In this article, Frederick Ryckbosch goes over the advantages and disadvantages of using Prometheus, and just how scalable it really is.

Data Acquisition Method: Push (CollectD, Zabbix, and InfluxDB); Pull (Prometheus, SNMP, and JMX).

What language is Prometheus written in? Most Prometheus components are written in Go. Some are also written in Java, Python, and Ruby.

Prometheus is an open-source API monitoring tool that scrapes API data from intermediary pushes for short-lived jobs. It can be used to collect and store data with a timestamp of when an event occurs, or the API is called.

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.

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.

Prometheus is easy to setup but it barely does anything. It gets really messy when one needs to gather application metrics (postgresql, cassandra, haproxy, java, etc...) and have dashboards and alerts going to different places (slack, email, etc...).

Datadog, like Prometheus, allows users to capture critical information including metrics. Datadog is a managed SaaS offering that collects core metrics for virtually any system or service. With Datadog, users are able to monitor and visualize usage metrics across their entire environment.

Prometheus is useful for monitoring app functionality, while Nagios is a very powerful platform for application networks and security. However, Prometheus has the edge in performance metrics.

Abilities: The primary focus of Nagios is more on application network traffic and security, while Prometheus mainly focuses on the applicative aspects of the application and its infrastructure. Prometheus is developed to collect data from applications that push metrics to their API endpoints (or exporters).

Prometheus is open source, and free. Splunk is a one-stop-shop for everything related to data management, and they can be used in a broad range of fields (IoT, IT, security, and business metrics). Splunk is a proprietary service that can't be used for free.

The Prometheus agent requires about 1 CPU core and 1 GB memory to collect 1 million metrics, as shown in the Stress test report for the Prometheus agent. The recommended CPU utilization and memory usage of the Prometheus agent are both 50% for the agent to properly collect data.

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).

How often does Prometheus scrape? ›

In this case the global setting is to scrape every 15 seconds. The evaluation_interval option controls how often Prometheus will evaluate rules. Prometheus uses rules to create new time series and to generate alerts. The rule_files block specifies the location of any rules we want the Prometheus server to load.

Prometheus's weakness was not fearing the Gods. Some of his powers were also his weaknesses. He used to it to outsmart and deceive Zeus and other Gods and Goddesses. There for, Zeus punished him by arresting him and bound him to a stake on Mount Kaukasos where the eagles were to feed on him.

How did Zeus punish Prometheus? According to one tale told by Hesiod, Zeus avenged himself on Prometheus by having him nailed to a mountain in the Caucasus and then sent an eagle to eat his immortal liver, which constantly replenished itself.

Prometheus is best known for defying the gods by stealing fire from them and giving it to humanity in the form of technology, knowledge, and more generally, civilization. In some versions of the myth, he is also credited with the creation of humanity from clay.

Prometheus will connect to Node Exporter using TCP port 9100 and HTTP protocol at given intervals to retrieve these metrics.

Prometheus is far more powerful than normal homies, being made from a fragment of Big Mom's very own soul. This gives the sun a will strong enough to resist the soul projection of the Yomi Yomi no Mi's user. However, Prometheus is still vulnerable to being injured by the user of the fruit.

According to Edith Hamilton's book "Mythology," the name Prometheus means "forethought," and he was "very wise, wiser even than the gods." Prometheus was said to have been so enthralled by his human creation that he stole fire from the gods to help the humans along.

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.

Prometheus is an open source monitoring system for which Grafana provides out-of-the-box support. This topic walks you through the steps to create a series of dashboards in Grafana to display system metrics for a server monitored by Prometheus.

Can I use Prometheus without Kubernetes? ›

To taste Hue prometheus metrics, you may set up a Prometheus server to scrape the metrics endpoint /metrics on a Hue server (which may not need to run in docker or Kubernetes). Here is the set up example on Ubuntu 16.4. Prerequisites: a Hue server running at localhost:8000.

Prometheus supports TLS and basic authentication over its HTTP endpoints. Scraping target using HTTPS instead of HTTP has been supported for a long time. You could fetch metrics using HTTPS, client-certificate authentication, and basi contentc authentication.

Prometheus includes a local on-disk time series database, but also optionally integrates with remote storage systems.

Prometheus is an open-source tool that provides monitoring and alerting for cloud-native systems, such as Kubernetes. It can collect and store measurements as time-series data, including a timestamp for each entry. Labels, which are optional key-value pairs, can also be collected and recorded.

The log files are matches line by line using a regular expression, and the matched data is stored in different variables. Then, the data of these variables are exported via grok_exporter. Once you add the grok_exporter server to Prometheus as a target, Prometheus can monitor the desired log files via grok_exporter.

Prometheus is an open-source monitoring and alerting tool. Prometheus can be used to monitor Python applications. Prometheus has an official Python client library that you can use on your Python project to export metrics (i.e. number of visitors, bytes sent or received).

So, If you're wondering if the police can track your phone numbers and IP addresses, the answer is - yes, they can. While the police cannot search your phone without a warrant, they have a legal right to watch what you do in public, on social media, and in your home and business.

Specialized IoT search engines like Rapid7 and MITRE track vulnerabilities known to specific devices. Using yet another IoT search engine like Shodan and ZoomEye, hackers can find devices connected to the internet, geolocation, port/operating system, services/host, and IP address.

In short, not really. But if they have a court order, they can request usage or connection logs. Overall, being completely anonymous and untraceable online is virtually impossible. A VPN is a great tool that gives you more privacy by masking your IP address, minimizing commercial advertising, and hacking attempts.

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.

Is Prometheus a DevOps tool? ›

Prometheus is a tool that every DevOps professional should be familiar with. It's an open-source system for monitoring services and alerts based on a time series data model. Prometheus collects data and metrics from different services and stores them according to a unique identifier—the metric name—and a time stamp.

The easiest way to monitor any Kubernetes workload is using Prometheus. It also holds true for a CI/CD pipeline.

Typically, Prometheus and Grafana training by DevOpsSchool will let you master the concepts in about 2 months if you devote 2 to 4 hours per week. The training takes place in such a way that you become proficient in almost all the concepts of Prometheus and Grafana can easily add certification to your resume.

Age Appropriate for: 15+. Cursing, implied sexual situations (kissing, but no nudity), sexual talk, and bunches of murder and bloodshed, including a Caesarean section-like procedure.

Prometheus is rated R by the MPAA for sci-fi violence including some intense images, and brief language.

Data will be automatically deleted after the storage retention time has passed. By default it is 15 days. If you want to delete specific data earlier, then you are able. You need to enable the admin api in Prometheus before you can.

Prometheus discovers targets to scrape from by using Service Discovery. A Kubernetes cluster already has labels and annotations and an excellent mechanism for keeping track of changes and the status of its elements. Hence, Prometheus uses the Kubernetes API to discover targets.

Prometheus gathers metrics from different systems by scraping data from HTTP endpoints. It uses this information to identify issues, such as when an endpoint is missing or should not exist or when a time-series pattern indicates a problem.

Prometheus is an open-source systems monitoring and alerting toolkit. You can configure Docker as a Prometheus target. This topic shows you how to configure Docker, set up Prometheus to run as a Docker container, and monitor your Docker instance using Prometheus.

How do you expose data in Prometheus? ›

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.
