The threshold options on the visualizations doesn’t show up on the graph. Grafana is not just for IT teams. An improvement to the thresholds control creates a more intuitive, user-friendly experience when creating single stat panels. Grafana also allows you to set up alerts based on the data stored in InfluxDB, notifying you when certain thresholds are crossed or unusual events occur. Grafana-managed rules inherit their model from Prometheus Alerting and extend it with greater flexibility—such as multi-data source queries, expression-based transformations, advanced alert conditions, images in notifications, custom states, and more. Learn how to monitor Apache Kafka performance with Prometheus JMX exporter and Grafana dashboards. What Grafana version and what operating system are you using? Grafana v9. Explore Grafana for data visualization, dashboards, and real-time monitoring of research and business data. 2 Windows 11 What are you trying to achieve? Set a threshold as a percentage of one query result out from the result of another query. When a threshold is exceeded or a condition is met, Prometheus sends an alert to Grafana, which then notifies you via email, Slack, or other chosen channels. This example shows how to use a distinct threshold value per dimension using multi-dimensional alerts and a Math expression. For example, to calculate P99: histogram_quantile(0. 16 in EKS What are you trying to achieve? Gauge where larger is better, smaller is worse, and thresholds work properly – i. As an example, you can use thresholds to assert that the system performs within your service-level objectives while the test runs. OR Is there a way to set threshold per row?. Hello, Is it possible to set thresholds from Maximum to Minimum under singlestat panel. 2. 3. I need to set different thresholds in one column. Sync data, automate reports, and enhance your Grafana workflow. Grafana-managed alert rules are the default way to create alert rules in Grafana. Configure thresholds In dashboards, a threshold is a value or limit you set for a metric that’s reflected visually when it’s met or exceeded. 99, sum by Grafana 沿 Y 轴在该值处绘制一条阈值线。 颜色：选择与颜色对应的条件，或定义自己的颜色。 自定义：定义填充颜色和线条颜色。 critical：填充和线条颜色为红色。 warning：填充和线条颜色为黄色。 ok：填充和线条颜色为绿色。 填充：控制是否显示阈值填充。 What Grafana version and what operating system are you using? Grafana 9. 9k 🚀 Implementing Effective Monitoring for Microservices In the world of microservices, monitoring is key to maintaining stability and performance. To do this, you can set thresholds to evaluate whether the test performs to a certain criteria. It must depend on values in other column. I would like to change the color of the value column on each row based on its compliance (green) or non compliance (red) to the max/min. Hope i make sense. What Grafana version and what operating system are you using? What are you trying to achieve? I want to set different thresholds for different rows in the table panel How are you trying to achieve it? Currently if we apply field override, it apply the threshold for the whole column . larger values are Green, smaller values are Yellow, smallest values are Red. I have two queries (one to calculate P95 and another for P99). A threshold is a value or limit you set for a metric that’s reflected visually when it’s met or exceeded. - Configure custom alerts based on CPU, memory, and network latency thresholds. 本文介绍了Grafana面板中如何设置时间序列数据的阈值，包括绝对值和百分比两种常见方式，以及如何通过Transform功能动态获取阈值。通过QueryA展示系统CPU负载，QueryB查询阈值，将QueryB的最新值应用到QueryA的图形上。动态阈值设置适用于Grafana 8.

Below is a step-by-step guide to setting thresholds based on This example shows how to use a distinct threshold value per dimension using multi-dimensional alerts and a Math expression. Thresholds are one way you can conditionally style and color your visualizations based on query results. 5 and Prometheus on the data collection side and I have a panel in my dashboard displaying a gauge. For example, if the value in the first column is “DVG-CUBE01-VRU1”, i need to set the threshold for value To prevent this, you can set a recovery threshold to define two thresholds instead of one: An alert transitions to the Pending or Alerting state when it crosses the alert threshold. May 21, 2025 · This document explains how to configure thresholds to determine when metrics should display as OK, Warning, Critical, or Disabled states, and how these thresholds affect the visual representation of the panel. This setup allows for real-time monitoring and immediate attention to potential issues. To prevent this, you can set a recovery threshold to define two thresholds instead of one: An alert transitions to the Pending or Alerting state when it crosses the alert threshold. 6 What are you trying to achieve? I have a table with three columns: value, min and max. How are you trying to achieve it? What happened? What did you expect to happen? Can you copy/paste the configuration(s) that you are having problems with? Did you receive any errors in the In dashboards, a threshold is a value or limit you set for a metric that's reflected visually when it's met or exceeded. The issue here though is Configure thresholds In dashboards, a threshold is a value or limit you set for a metric that’s reflected visually when it’s met or exceeded. That should display a suite of gauges, one for each probe location, and I would like each gauge to have threshold computed from the corresponding temperatureProbeUpperNonCriticalThreshold and temperatureProbeUpperCriticalThreshold values. I would like it to display yellow below 200, and red below 50 I’m trying to add a dynamic threshold line to this time series. 0. We found a Complete guide to infrastructure monitoring with Prometheus, Grafana, and AlertManager. 1及以上版本，允许根据查询结果动态设定阈值。 In Grafana Alerting, you can also configure recording rules, which pre-compute queries and save the results as new time series metrics for use in other alert rules or dashboard queries. I would like to use thresholds, so that when the value goes beyond 10s should be yellow (warning) and red if it goes over 30s. This integrated approach provides a powerful and comprehensive monitoring solution. The solution could be to define alerts into multiple buckets depending on traffic and update the alerts. Grafana connects to InfluxDB to access and display the data in a visual format, such as graphs and charts. ⚡ Built a real MongoDB monitoring & alerting setup Recently put together a production-ready observability stack for MongoDB using Grafana + Prometheus. Label-only indexing vs full-text search, LogQL vs SQL, logs-only vs full MELT observability on S3. Think of them as traffic lights for your data. We mainly achieve this by exposing some kind Grafana Loki & Promtail: Deployed for centralized logging. Understanding Grafana Thresholds So, what exactly are Grafana thresholds, you ask? In essence, they are predefined levels or values that you set within your Grafana dashboards to visually distinguish between different states of your metrics. e. Enter a new threshold value, or use the up and down arrows at the right side of the field to increase or decrease the value incrementally. I want to create a dynamic threshold. While thresholds are typically set using numerical values, it is possible to define thresholds based on string values, such as “production,” “staging,” or “development,” to modify the visualization color dynamically. Using thresholds, you can color grid lines and regions in a time series visualization: 🚀 Developing a Robust Monitoring System with Prometheus and Grafana In the world of software development, monitoring is key to maintaining stable and scalable systems.
