Managing and visualizing custom application logs using open-source ELK and Grafana\u2014without vendor lock-in or licensing costs.<\/strong><\/p>\n This log management success story explains how Cetin Kocaman\u2019s team needed better visibility into unstructured Windows application logs, traditional monitoring tools couldn’t meet the challenge. Logs were scattered, lacked structure, and triggered no alerts for critical keywords<\/span> “Thanks to Cetin KOCAMAN”<\/a> \u00a0Bigs\u202fBili\u015fim stepped in, architecting a cost-effective, open-source log management stack<\/strong> combining:<\/span><\/p>\n Elasticsearch, Logstash & Filebeat<\/strong> for log ingestion and indexing<\/span><\/p>\n<\/li>\n Kibana<\/strong> for deep log querying and troubleshooting<\/span><\/p>\n<\/li>\n Grafana<\/strong> for dashboard metrics and alerting<\/span><\/p>\n<\/li>\n<\/ul>\n \u2705 Agentless collection<\/strong> from Windows SMB shares and local storage<\/span><\/p>\n<\/li>\n \u2705 Custom parsing<\/strong> via Logstash and Filebeat to handle unstructured formats<\/span><\/p>\n<\/li>\n \u2705 Rich visual insights<\/strong> in Kibana, enabling root-cause analysis<\/span><\/p>\n<\/li>\n \u2705 Grafana dashboards + alerts<\/strong>, configured to email teams when keywords (e.g., \u201cWRNDBSLOGDEF0000000002\u201d)\u00a0<\/span><\/p>\n<\/li>\n<\/ul>\n This stack empowers teams to monitor real-time log rates and automate issue detection\u2014at zero license cost.<\/p>\n No vendor lock-in<\/strong>: Completely open-source, you control your data<\/p>\n<\/li>\n Lightweight & flexible<\/strong>: Ideal for custom or legacy applications<\/p>\n<\/li>\n Full observability<\/strong>: Kibana for query-driven analysis; Grafana for metrics and alerts<\/p>\n<\/li>\n Scalable & extensible<\/strong>: Modular\u2014add Beats, alert channels, data visualizations as needs evolve<\/p>\n<\/li>\n<\/ul>\n Expert implementation<\/strong> of ELK stacks on CentOS, with secure Nginx proxying<\/p>\n<\/li>\n Custom alert logic<\/strong> built in Grafana via keyword triggers and SMTP integration<\/p>\n<\/li>\n Smooth onboarding<\/strong> via documentation, training, and hands-on setup<\/p>\n<\/li>\n Ongoing support<\/strong> and future-proofing for evolving log requirements<\/p>\n<\/li>\n<\/ul>\n Here are the details customers most often ask about this log management success story.<\/p>\n Licensing costs and vendor lock-in were the main concerns. By building on Elasticsearch, Logstash, Filebeat, Kibana, and Grafana, the customer keeps full ownership of the stack and can extend it freely, which made this log management success story sustainable well beyond the initial rollout.<\/p>\n Logs are collected directly from Windows SMB shares and local storage rather than through installed agents, which kept rollout simple and avoided touching production systems. This approach is a good fit for organizations that want centralized visibility, similar to how our Monitoring & Log Management<\/a> service is delivered for other customers.<\/p>\n In most cases, yes. Our team follows the same process of assessing your log sources, designing parsing rules with Logstash and Filebeat, and building Kibana and Grafana dashboards tuned to your alerting needs. Teams comparing platforms can also review Elastic’s own documentation for the ELK Stack<\/a> to understand its broader capabilities.<\/p>\n Ready to transform your logs into actionable insights\u2014license-free?
