Initial CV-aligned infrastructure portfolio

Rework portfolio around Linux operations, Zabbix monitoring, migration validation, and ELK/Grafana log observability.

Add AAP-style LVM resize workflow, Zabbix server/proxy/agent automation assets, Linux/AIX monitoring templates, and updated validation CI.

Architecture Overview

Portfolio Shape

This repository is organized around professional infrastructure work that maps to the CV:

  migration-validation-framework/
  log-observability-elk-grafana/

devops-labs/
  future side projects only when ready

Project Roles

Linux Operations Automation

Operational automation for Linux server work:

provisioning and baseline configuration,
patching and hardening,
service/failure simulation,
AAP-style LVM filesystem resize workflow with before/after evidence.

Zabbix Monitoring + Incident Response

Simple checks and OS monitoring:

Zabbix server/proxy/agent automation structure,
active and passive proxy design,
Linux and AIX monitoring templates,
maintenance and incident response runbooks.

Migration Validation Framework

Evidence tooling for platform/storage migrations:

before/after snapshot collection,
drift detection,
risk assessment,
JSON and HTML reports.

Log Observability ELK/Grafana

Log monitoring and incident evidence:

Filebeat ingestion,
Logstash parsing,
Elasticsearch storage,
Kibana/Grafana review surfaces,
incident log simulation.

Design Principles

Keep implemented work separate from roadmap ideas.
Prefer reviewable automation and evidence over overbuilt local labs.
Make every project independently validatable.
Treat Zabbix and ELK/Grafana as complementary monitoring tools:
- Zabbix for simple checks and OS health,
- ELK/Grafana for logs and observability evidence.
