  • Monitoring & Visualization Create and maintain Kibana dashboards tailored for infrastructure monitoring, providing real-time visibility into device health, performance, and security events.
    Develop alerting rules for critical infrastructure events (e.g., interface down, storage threshold breaches, hardware failures).
  • Automation & Integration Automate device onboarding and log pipeline deployment using scripting (Shell, Python) and configuration management tools.
    Integrate log monitoring with ITSM platforms (e.g., ServiceNow) for automated incident creation and remediation workflows.
    Maintain version control of pipeline configurations and scripts using Git.
  • Operational Excellence Perform routine health checks and troubleshooting of ELK Stack components and infrastructure log sources.
    Collaborate with network, storage, and server teams to ensure comprehensive log coverage and rapid incident response.
    Develop and update runbooks and SOPs for infrastructure log onboarding, monitoring, and incident management.

  • Proven expertise onboarding and normalizing logs from a wide range of infrastructure devices (network, storage, server).
  • Deep understanding of log formats (syslog, SNMP, vendor-specific), device management protocols, and log forwarding best practices.
  • Experience designing and optimizing Logstash pipelines for high-throughput environments.
  • Strong scripting skills for automation (Shell, Python).
