Application Performance Monitoring & Observability: Configure and utilize APM, monitoring and log analytics platforms to monitor application availability, transaction performance, response times, HTTP errors, application exceptions, dependencies and service health.
JVM Performance Monitoring & Diagnostics: Monitor JVM heap utilization, Garbage Collection, thread pools and connection pools. Capture and perform initial analysis of Thread Dumps, Heap Dumps and GC logs to support diagnosis of memory issues, thread contention, application hangs and performance degradation.
Application Incident Triage & RCA: Perform L2 application and middleware troubleshooting for application degradations, errors and outages. Identify whether issues originate from application, middleware, database, infrastructure or network components and coordinate with relevant teams for resolution and RCA.
Application Deployment & Release Support: Support application deployments, middleware configuration changes, patch implementation, SSL/TLS certificate renewal, release validation, rollback and post-deployment verification through established Change Management processes.
Monitoring & Alert Management: Configure and maintain monitoring dashboards, alerts, thresholds and escalation mechanisms. Identify application performance degradation and proactively escalate critical issues.
Log Monitoring & Analysis: Analyse application, middleware, access, error, JVM and system logs to identify failures, recurring errors, abnormal behaviour and performance issues.
Automation & Scripting: Develop and maintain scripts for application health checks, service validation, alert verification, log parsing, reporting and routine middleware operations using Bash, Python, PowerShell or equivalent technologies.
Application Dependency Monitoring: Monitor and troubleshoot application dependencies including databases, APIs, web services, DNS, load balancers, network connectivity and other supporting services.
Security & Compliance Support: Support middleware hardening, SSL/TLS configuration, certificate lifecycle management, security patching, vulnerability remediation and access-control requirements.
Change & Incident Management: Follow established Incident, Problem and Change Management processes and participate in production releases, critical incident handling, RCA and corrective/preventive action activities.
