Upgrades to monitoring components

We’ve rolled out some minor updates to the monitoring components.

List of updated components:

  • grafana: v6.6.2 –> v6.7.1

    Several enhancements and bug fixes.

  • prometheus: v2.14.0 –> v2.15.2

    Several enhancements and bug fixes, including memory usage improvements.

  • alertmanager: v0.19.0 –> v0.20.0

    Several enhancements and bug fixes.

Additionally there’s a bug in the Helm charts we use, causing Grafana datasources to be unconfigured in some cases. For now we’ve reverted to a previous version (no impact on our deployed components).
