Use the armclient tool to automatically generate Grafana dashboards which you can import into your Grafana server. This assumes that you are familiar with Grafana and the Azure Monitor data source plugin. For more information, please refer to the following article:.

Create a service principal which has Reader permission to access your Azure subscription. You will need the name of the Azure Monitor data source on your Grafana server and the ARM resource type that you blue book of mandolins to generate dashboards.

The armclient tool will generate dashboard JSON files -- one for each region and one for all regions. The armclient automatically pulls dashboard templates from this GitHub repository.

To contribute new dashboard templates, please following the following instructions. Note: In your dashboard, you should only select single Azure resource for each of the charts. For example, if you are creating a dashboard specific to Azure Storage account latencies, you could create the following directory structure:.

Grafana dashboard templates for Azure. Branch: master.Screen Shot at 1. How could I form a graph hiring over period of time using my data set?

Sorry but my basic concepts are not clear. Please read the time series query section very carefully of using mysql in Grafana documentation. This value must be numeric. So 1 as value would for example work to plot the result in a graph panel. And my data is in time series but still I could not able to plot the graph. Screen Shot at 4.

Obviously depends on how you want to visualize this, but with a graph panel I think the result will be very odd. Seems like you have very old data, decades ago for example. In that case I would suggest that you use the X-Axes Mode Time instead and a query similar to the following. Then you could change some panel settings. Thank you so much mefraimssonas I could see how data representation get changed over my operations it is making some sense to try out different combinations.

The graphs i linked are using graphite datasource. The graphite datasource supports functions. You cannot use them for mysql though.

Docs Grafana. Hi, Please read the time series query section very carefully of using mysql in Grafana documentation. I just want to start with my very first graph. How that can be achived?Comment 0. During the course of our careers, we deal with database servers handling thousands and sometimes millions of transactions. We also face different issues like table locks, slow queries, and max connections reached, to name a few.

In order to solve these issues, most of the time, we get the information from logs and inspect variables or performance schema. What if we could get visual insights of what is happening inside our database server so that we could take any preventive or corrective actions? There are multiple options available in both the commercial and open source world to provide visual insights, but Prometheus and Grafana are among the leaders in the open source space. Grafana is one of the leading open-source metrics monitoring and visualization tools.

If you are good with SQL queries, then, of course, you can build monitoring using queries only, as the MySQL plugin allows you to run queries directly, but that is going to be a hectic and lengthy task. Also, Prometheus is a "Pull" based system, which means the Prometheus server fetches called "scraping" in the Prometheus world the metrics from the running application periodically.

But the MySQL server does not provide any endpoint from which Prometheus can scrape the metrics directly. To solve this issue, the Prometheus community has developed exporters.

The job of an exporter is to extract metrics from a target application using the language the underlying application understands and then expose them over REST. From there, the Prometheus server can scrape the metrics. Prometheus : prometheus MySQL : 5. I assume that you have already set up Prometheus with Grafana. If not, then you can follow this article where we have seen how to setup and add Prometheus as a datasource in Grafana. The exporter needs some grants on the target MySQL instance so that it can query the server for metrics.

It is better to create a separate user for the exporter and add grants for them. It is always good to set a max connection limit for the user to avoid overloading the MySQL server. If you have been using ". I assume that you already have a running Grafan instance and have added Prometheus as a data source in Grafana. If not, then please follow the steps in this article.

In this article, we are going to monitor the number of "Current Active Connections" and "Maximum number of connection used" since the server started. Select "Graph" from the options. This will open a blank graph panel. From the tabs below, click on the "General" tab.

In this tab, you can provide the generic information about the graph, such as name and description. Let us add "Connections" in the "Title" field. I am using "Connection Monitor. Select the "Metrics" tab. Adjust options for axes from the Axes tab. I am only changing the minimum value to "0" zeroand the rest I am leaving to defaults. Configure your legend related settings from the "Legend" tab.

This will affect how the legends are shown on the panel with what options and at what place they are displayed. The graph should be presented as lines, bars, or points and can be configured from the "Display" tab. You can also control the width and staircase options from here.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Now that your database is connected, you are ready to create your first dashboard!

2MySQL Simple Dashboard

I didn't really do anything. I just noticed that one of the panels on my dashboard is sort of broken - it is missing the last 2 hours of data. It was working perfectly in the previous version of Grafana 5. The panel is a simple graph, displaying an hourly bar histogram of the data collected during the corresponding hour.

So, why were the last two hours missing? I hadn't changed anything on the panel settings or in the MySQL query that feeds it the data. Here timestamp is a column in a table of the MySQL database with the format datetime. The above query was generated at local time. Do you see what is happening? The "from" and "to" times passed to the query are in UTC time and not in local time - despite the dashboard being configured to use local time. As a result, the query fetches data for the wrong time period.

Now, I did find a workaround for the problem. This works with UTC times only and the data is fetched as it should be. I had opened an issue on the subject, but you closed it and didn't fix that problem, although the fix is rather trivial - I managed to figure it out despite that I don't know Go.Grafana Panel Format Table. Grafana Panel Format Time series. If you want to group by time group by hour or day for examplehere is one way there is another example in the docs that uses DIV :. And looks like this:.

Hope that these examples are clear. Any tips on how we can keep it short but explain the column names better in the Help section for the MySQL data source? Thank you so much, your answer is very clear and everything works fine now!

I can now go further with Grafana. But this could also confuse some peopleā€¦. Can i know how to use epoch time of mysql db in grafana?? Can you show your query and the macro or function you are using and any relevant information about the mysql db schema? I just tested with an int: of type int 11 and my query looked like this:.

And do you need to be able to zoom in to that level in Grafana? Grafana only supports showing down to microseconds.

How to use Grafana with AWS CloudWatch

Epoch time stamp is already in microsecondsNow Grafana is converting it to nano-seconds. Can you give an example of one of your epoch timestamps that have in the customerAffected table.

But that is in milliseconds and not micro or nano seconds. So your solution with dividing by is the best you can do currently and that means you lose the millisecond precision. Once we upgrade the mysql golang driver it got updated with types support recentlythen we will be able to support any datetime format like the Postgres data source does. I will be doing that in January. Thank you for the response daniellee. Kindly update the post. The upgrade to the MySQL driver is in the latest beta which means it is possible to do add this feature now but I have not yet got around to supporting microseconds yet.

Might have time before the stable release but it is more likely that it will be in Grafana 5. I have only week data for hosts. There is no daily data on database. I can select following data and try to graphs thats. Downtime is value and week is time.
