From 4f2d39af03b274f806e4d744f7f1a3312ea75a4f Mon Sep 17 00:00:00 2001 From: Andras Bacsai <5845193+andrasbacsai@users.noreply.github.com> Date: Tue, 18 Nov 2025 12:30:50 +0100 Subject: [PATCH] refactor: send immediate Traefik version notifications instead of delayed aggregation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move notification logic from NotifyOutdatedTraefikServersJob into CheckTraefikVersionForServerJob to send immediate notifications when outdated Traefik is detected. This is more suitable for cloud environments with thousands of servers. Changes: - CheckTraefikVersionForServerJob now sends notifications immediately after detecting outdated Traefik - Remove NotifyOutdatedTraefikServersJob (no longer needed) - Remove delay calculation logic from CheckTraefikVersionJob - Update tests to reflect new immediate notification pattern Trade-offs: - Pro: Faster notifications (immediate alerts) - Pro: Simpler codebase (removed complex delay calculation) - Pro: Better scalability for thousands of servers - Con: Teams may receive multiple notifications if they have many outdated servers 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- app/Jobs/CheckTraefikVersionForServerJob.php | 22 +++- app/Jobs/CheckTraefikVersionJob.php | 55 +------- app/Jobs/NotifyOutdatedTraefikServersJob.php | 68 ---------- tests/Feature/CheckTraefikVersionJobTest.php | 46 +++---- tests/Unit/CheckTraefikVersionJobTest.php | 126 +++---------------- 5 files changed, 56 insertions(+), 261 deletions(-) delete mode 100644 app/Jobs/NotifyOutdatedTraefikServersJob.php diff --git a/app/Jobs/CheckTraefikVersionForServerJob.php b/app/Jobs/CheckTraefikVersionForServerJob.php index 665b7bdbc..88484bcce 100644 --- a/app/Jobs/CheckTraefikVersionForServerJob.php +++ b/app/Jobs/CheckTraefikVersionForServerJob.php @@ -3,6 +3,7 @@ namespace App\Jobs;
