prom_ex v1.7.0 Release Notes

Release Date: 2021-03-01 // about 3 years ago

  • ➕ Added

    • ➕ Added ability to execute arbitrary function on resulting dashboard for user customization.
    • The GrafanaClient is now considered part of the public API, and users can interact with Grafana directly. For example, users can publish their own Grafana annotations in addition to the annotations provided by PromEx.
    • ➕ Added the ability to start GrafanaAgent via a port so that metrics can be published via remote_write to an other Prometheus instance. For example, if you are using GrafanaCloud, you can use PromEx to push metrics right to GrafanaCloud using the appropriate configuration. This feature is currently only available for Linux and OS X.
    • 🔧 The ETSCronFlusher GenServer can now be configured to flush the ETS buffer at whatever time interval you desire. The default is still every 7.5s.

    🛠 Fixed

    • Broadway metrics prefix.
    • Broadway dashboard panel descriptions and titles.
    • Fixed the :default_selected_interval option in all dashboards.
    • 🔌 Phoenix plugin manual metrics were ignoring the metric prefix option.

    🔄 Changed

    • 🔊 Application plugin no longer logs warnings for missing GIT env vars.
    • 🔊 LifecycleAnnotator no longer logs warnings for missing GIT env vars.
    • 🔌 All plugin distribution buckets have been redefined. The reason for this being that prior to PromEx 1.7, some of the distribution buckets were a bit wasteful and were not adding value in terms of metrics data points. With this change, users should notice a decline in data point cardinality without compromising resolution.
    • 🔌 Application plugin has changed how it fetches dependency information. It is now using Applciation.spec/1 to get the list of applications that are started with your application. This should reduce noise in the Grafana dashboard as all the default OTP and Elixir applications will not show up.
    • 0️⃣ All Grafana dashboard now have a default panel sort order where the largest timeseries plot is first in the list when hovering over the visuals.
    • 👷 All Grafana dashboards now filter the instance filter based on the selected job filter.
    • 🚚 The Oban plugin no longer collects metrics related to :circuit events as those have been removed from Oban starting with version 2.11 (https://github.com/sorentwo/oban/pull/606). The Oban dashboard will be updated in the next release to remove the unused panels.
