DevOps

4ops delivered a full observability stack tailored to our restricted infrastructure environment. They configured a ClickHouse Exporter to expose query rates, merge queue depth, replication status, memory usage, and table-level performance as Prometheus-compatible metrics, hardened to our internal network interface only. An internal Prometheus instance scrapes this data with all targets, retention settings, and alert rules managed via Ansible configuration files. They built a custom Grafana dashboard covering both system metrics—CPU, memory, disk I/O, ClickHouse merge queue, replication lag, query latency—and business-level KPIs like user activity rates, matching throughput, and active session counts. They also provided full-stack Ansible automation playbooks that deploy and configure the entire monitoring environment identically on any new server with no manual steps, plus deployment documentation that let our team get up to speed quickly.
