What is Promtail?

Promtail is an agent which ships the contents of local logs to a private Grafana Loki instance or Grafana Cloud. It is usually deployed to every machine that has applications needed to be monitored.

What is Grafana Loki?

Loki is a horizontally scalable, highly available, multi-tenant log aggregation system inspired by Prometheus. It is designed to be very cost effective and easy to operate. It does not index the contents of the logs, but rather a set of labels for each log stream.

What is Grafana metric?

Metrics tell you how much of something exists, such as how much memory a computer system has available or how many centimeters long a desktop is. In the case of Grafana, metrics are most useful when they are recorded repeatedly over time.

What is Grafana agent?

The Grafana Agent is a telemetry collector for sending metrics, logs, and trace data to the opinionated Grafana observability stack. It is commonly used as a tracing pipeline, offloading traces from the application and forwarding them to a storage backend.

FOSDEM talk: Getting started with Grafana Tempo, Joe Elliot

Is Grafana push or pull?

For anyone who finds this thread in the future, it turns out that the grafana cloud agent does exactly what I'm after here, it's an agent that you install on a client server, which seems to do the pushing of data instead of having to have open ports that get queried by the monitoring system.

Can I 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 active time series?

An active series is a time series that receives new data points, or samples.

What are metrics used for?

Key Takeaways

Metrics are measures of quantitative assessment commonly used for comparing, and tracking performance or production. Metrics can be used in a variety of scenarios. Metrics are heavily relied on in the financial analysis of companies by both internal managers and external stakeholders.

What is Loki vs Prometheus?

Loki is like Prometheus, but for logs: we prefer a multidimensional label-based approach to indexing, and want a single-binary, easy to operate system with no dependencies. Loki differs from Prometheus by focusing on logs instead of metrics, and delivering logs via push, instead of pull.

Is Grafana better than Kibana?

Grafana is better suited for applications that require continuous real-time monitoring metrics like CPU load, memory, etc. Kibana is better suited for log file analysis and full-text search queries. Grafana gives custom real-time alerts as the data comes; it identifies patterns in the data and sends alerts.

What is Thanos software?

Overview. Thanos is a set of components that can be composed into a highly available metric system with unlimited storage capacity, which can be added seamlessly on top of existing Prometheus deployments. Thanos is a CNCF Incubating project.

What is Loki in Kubernetes?

Open sourced by Grafana Labs during KubeCon Seattle 2018, Loki is a logging backend optimized for users running Prometheus and Kubernetes with great logs search and visualization in Grafana 6.0. Grafana Loki is a set of components, that can be composed into a fully featured logging stack.

Is Loki a Prometheus?

About Loki

What is KPI in Grafana?

Performance monitoring support enables a Mattermost server to track system health for large Enterprise deployments through integrations with Prometheus and Grafana.

Does Grafana expose metrics?

Grafana provides a flexible and visually pleasing interface to view graphs of your metrics stored in Prometheus.

What is Grafana monitoring?

Grafana is an open source solution for running data analytics, pulling up metrics that make sense of the massive amount of data & to monitor our apps with the help of cool customizable dashboards.

What are the four 4 main components of a time series?

These four components are:

• Secular trend, which describe the movement along the term;
• Seasonal variations, which represent seasonal changes;
• Cyclical fluctuations, which correspond to periodical but not seasonal variations;
• Irregular variations, which are other nonrandom sources of variations of series.

What is the difference between panel data and time series data?

Time series data means that we have data from one unit, over many points in time. Panel data (or time series cross section) means that we have data from many units, over many points in time.

What are the types of time series?

The four variations to time series are (1) Seasonal variations (2) Trend variations (3) Cyclical variations, and (4) Random variations. Time Series Analysis is used to determine a good model that can be used to forecast business metrics such as stock market price, sales, turnover, and more.

What is better than Grafana?

Datadog, Kibana, Prometheus, Graphite, and Splunk are the most popular alternatives and competitors to Grafana.

Is Grafana same as tableau?

Key differences between Grafana and Tableau. The concept of Grafana is very broad, while Tableau is more focused on business intelligence. Grafana is well suited for working with time-series, application monitoring, and server monitoring. Working with servers can be a bit less comfortable with Tableau.

What are the limitations of Grafana?

Grafana has a limitation where it doesn't have a native capability to aggregate data from multiple sources as it isn't a data store of its own which leads to limited ability to handle correlation across multiple data types.
