Grafana postgresql query example

Query: This variable type allows you to write a data source query that usually returns a list of metric names, tag values or keys. For example , a query that returns a list of server names, sensor ids or data centers. Interval: This variable can represent time spans.

Using Microsoft SQL Server in Grafana. Usage of time_sec will eventually be deprecated. SELECT value FROM table WHERE $__timeFilter(time_column). How to read Postgres SQL data into.


The query: could include any SQL statement. How can I achieve this with my database ? Can anybody share some links or information about how to do the export of data from postgres to Grafana. Grafana does not validate that the query is safe. This information would be useful for plotting the real time graph for my application debugging. This returns the correct value, wich changes trought time… But grafana is not keep track of the changes so it cannot produce the graph.

The example we saw today used static data, but it can be easily used with streaming data from performance monitoring tools or IoT devices. PostgreSQL ’s statistics collector automatically gathers a substantial number of statistics about its own activity. Main goals of this project are extend Zabbix capabilities for monitoring data visualization and provide quick and powerful way to create dashboards. It produces cool graphs and is relatively easy to setup. Struggled with this, hope it helps someone.


One of the most resource intensive queries for Zabbix API is the history query. For long time intervals history. This is, of course, possible with this plugin - thanks to the Query block you can define a custom Statement, fetch its and store it as metric. PostgreSQL - SELECT Query - PostgreSQL SELECT statement is used to fetch the data from a database table, which returns data in the form of result table.


I hoped that the GUI would be querying data source and offering valid entries for each field (as the video using Graphite seems to do) but no luck. The redhat contrib script for example , will not work on a Debian system because it depends on functions defined only on Redhat or CentoS systems. Leave it blank if only default retention policy used. MySQL, PostgreSQL , InfluxDB are supported as sources of historical data for the plugin.


Enable alerting: enable limited alerting support. Our open source time series data platform is built from the ground up to integrate real-time analytics, event handling, and time-based data. In an enterprise environment it is sometimes necessary to keep data in a traditional, general purpose. But for now, we encourage you to take the time to read the tutorial on Getting started with Prometheus, PostgreSQL , and TimescaleDB.


This is the first of the dashboards “ PostgreSQL Queries Overview” that shows information about all queries and databases. Please notice that the query id is clickable and leads to the second dashboard “ PostgreSQL Query Drill-Down”. So you can check charts related to a selected query.


Query editors help query data sources and are customized to implement the specific features and capabilities provided by the data source. Or do I need to reach into another toolbox? Every project is different, and often the requirements can be different.


So this question by itself is impossible to answer without qualifiers.
