timeShift(GrafanaBuzz, 1w) Issue 8

Published: 11 Aug 2017 by Trent White RSS

Many people decide to take time off in August to enjoy the nice weather before Fall, but I’ve been surprised at the number of Grafana related articles that I’ve come across this week. This issue of timeShift, contains articles covering weather tracking, home automation and a couple of updates to native Plugins from the core Grafana team.


Latest Release

Grafana v4.4.3 is Available for download
To see the full changelog, head over to our community site.



From the Blogosphere

  • Trending & Analyzing SmartThings Devices (Part 1 of 4): Home Automation is an exciting field. The development of new technology and protocols, and the consumerization of those capabilities have been happening at a rapid pace. However, some of these home automation platforms don’t leverage the data for analytics and trending. Michael had a busy weekend writing all four parts in a fascinating series about the sensors he’s using, how he’s collecting the data and storing it in InfluxDB, and building a dashboard in Grafana to maximize the value of his home automation data.

  • Adding Live Weather to Your Grafana Home Dashboard: One of the key features in Grafana is how it allows you to unify your data from multiple data sources. In this post, Michael builds upon the dashboard he created in his previous series, which tracks his SmartThings devices, to include local weather data from the DarkSky API.

  • In Search of the Perfect Dashboard: InfluxDB, Telegraf and Grafana - Part IX (Monitoring Zimbra Collaboration): Jorge continues his quest to build the perfect dashboard in part nine of the ten part series. This installment covers monitoring a Zimbra Collaboration environment.

  • How To Monitor A Træfik Reverse Proxy With Prometheus: Træfik is a reverse proxy and load balancer that dynamically listens to your Orchestrator, (i.e.: Docker) and knows each time a container is added, removed, killed or upgraded, and can generate its configuration automatically. Since Traefik exports metrics in a Prometheus friendly format, you can present this data alongside your other metrics in Grafana! Brian shows you how.

  • Monitoring Raspberry Pies with Grafana: Who doesn’t love pi? This post walks you through installing Telegraph on a Raspberry Pi and setting up InfluxDB and Grafana to monitor those devices.

  • Grafana and InfluxDB: So you’ve got Grafana and InfluxDB installed, now what? Bjorn walks us through creating our first dashboard, and the different tabs in the interface to make our data legible and beautiful.



Grafana Plugins

With Summer vacations in full swing, additions and updates of Grafana Plugins from the community slowed a bit this week. We have a number of Plugins almost ready to announce, but require changes from the authors before they can be published. Instead, we would like to highlight a few of the new core Plugins that have had some exciting recent updates: the MySQL Data Source and the Elasticsearch Data Source.

UPDATED PLUGIN

MySQL Data Source - This week we added support for creating Template Variables with MySQL. It is available in nightly builds and will be included in the next major release.

When you create a Template Variable it appears as a dropdown at the top of the dashboard and you can then use the variable in queries (where hostname is the template variable):

                sql
                SELECT
                  UNIX_TIMESTAMP(atimestamp) as time_sec,
                  aint as value,
                  avarchar as metric
                FROM my_table
                WHERE $__timeFilter(atimestamp) and hostname in($hostname)
                ORDER BY atimestamp ASC
            

A new feature included in this change is the ability to create key/value Template Variables. The options in the Variable dropdown can have a text/key and value. This allows you to have a friendly name as the text and an id as the value. For example, hostname(server1, server2) as the text and id(1,2) as the value.

Check out the documentation for more details.

This week’s MVC (Most Valuable Contributor)

It’s only fitting that this week’s MVC is a contributor who helped with updating the MySQL Data Source.

reyjrar (Brad Lhotsky)
reyjrar submitted a PR for macros in the MySQL data source that enables queries where the timestamp is stored as UNIX epoch. Thank you for taking the time to try out an alpha feature and contributing back to Grafana!



Tweet of the Week

We scour Twitter each week to find an interesting/beautiful dashboard and show it off! #monitoringLove

Glad you fixed the memory leak @tlhunter, but wow - that’s one hypnotic graph :)
