Is there experience supporting a project in production? Incident analysis, monitoring with graphs, logs.

Yes, experience supporting production projects includes regular monitoring of service status using dashboards (e.g., Grafana, Prometheus) and log analysis (ELK stack: Elasticsearch, Logstash, Kibana). When incidents occur, metrics and logs are first collected to understand the nature of the problem — for example, increased response times, errors in logs, or service outages. Then, cause analysis, fixes, and deployment of patches are carried out. Automation of alerts and creation of runbooks for quick response are important.

Example: when there is a sharp increase in service response time on Grafana, it shows that the CPU on the server is at 100% load. Log analysis reveals frequent database connection errors. This may indicate issues with the connection pool or network, requiring configuration adjustments or scaling.
