Version 1.3.0 (April 24th 2024)

Major changes

  • Added a new "Kube-Watcher" mode! This one allows to have a minimal
    monitoring of any PostgreSQL cluster running in Kubernetes, whatever
    the operator is, since it only uses 2 kubectl commands, in a loop,
    to create the monitoring. See examples in examples/Kube-Watcher/
    and the relevant parts in the documentation on how to use it !

    • TL,DR: simple as pgSimload -kube <kube.json>

    • Very special thanks to Brian Pace from Crunchy Data, since he
      shared with me his script that was doing that, exactly,
      I found that it could be interesting to have it in pgSimload !

    • Special thanks to "Pierrick" from CloudNativePG Slack, that helped
      me find the right labels and selectors for that operator to be used
      in the kube.json configuration file !

  • documentation update to describe the new "Kube-Watcher" mode.

Minor changes

  • changed the way the screen is refreshed in Patroni-Watcher, for better
    performances and less output in the terminal

    • moved from github.com/inancgumus/screen, screen.Clear() and
      screen.MoveTopLeft()

    • to simplied ANSI's fmt.Printf("\x1bc")

    • please let me know if this change break something for you, I can
      revert that easily in case. I do really lack feedback from pgSimload
      users!

  • simplier way of coding (most often, output messages) strings to be
    used in output: A+=B instead of A=A+B. (/me noob)

  • added 3 new functions to better padding (left/right) and count length of
    some output strings (eg podname lenght in Kube-Watcher mode, to align
    the outputs when more than 1 cluster is listed in this mode)

  • added K8s_selector field in patroni.json configuration file for
    Patroni-Watcher, so it can be monitoring any namespace other than the
    default set with, typically, kubectl config set-context --current --namespace=<namespace_name>

  • renamed in doc, including examples directory and in executables'outputs
    everything to be consistent among the 3 modes: "SQL-Loop", "Patroni-Watcher"
    and the new "Kube-Watcher" in version 1.3.0

  • lots of doc review, many errors find and corrected
