Many Grafana users export images of their dashboard panels. This feature powers the ability to receive alerts with a rendered image of the panel attached, which is valuable for quickly spotting if something is about to go sideways in production. Since Grafana v2.0, when support for server-side rendering of dashboard panels as images was introduced, PhantomJS has served as the built-in image renderer that enables this feature.
There are instances in life when isolation is actually welcome. One of those instances pertains to the I in the acronym ACID, which outlines the key properties necessary to maintain the integrity of transactions in a database. The time series database (TSDB) embedded in the Prometheus server has the C (consistency), the D (durability), and – somewhat debatable – the A (atomicity). But up until and including Prometheus v2.16, it did not have the I (isolation).
The Grafana and Metrictank/Graphite teams have been hard at work to deliver an exciting new feature for the upcoming Grafana v7.0 release: a rollup indicator and series lineage metadata breakdown for Metrictank. This blog will cover the new functionality around Metrictank metadata, the rollup indicator, and the lineage visualization coming in 7.0.
Grafana v7.0 is coming next month! Here’s a sneak peek of one of its features: the query history in Explore. Query history lets you view the history of your querying. All queries that have been starred in the Query history tab are displayed in the Starred tab. This allows you to access your favorite queries faster and to reuse these queries without typing them from scratch.
Since the beginning of the Cortex project, there was a flaw with the ingester service responsible for storing the incoming series data in memory for a while before writing it to a long-term storage backend. If any ingester happened to crash, it would lose all the data that it was holding.
Grafana v7.0 is coming next month! Here’s a sneak peek of one of its features: a brand-new table panel. The current (old) table panel has accumulated a ton of feature requests over the years, and we are excited to finally close many of them in 7.0 with this new table panel. Among the many new things this panel can do is to include other visualizations inside cells. For example, you can configure a cell style (per column) to render the value as a bar gauge.
