As a team of cloud management and monitoring, - we've developed the integrated monitoring system with prometheus, grafana and alertmanager. - We've developed our own cloud management system and portal for infastructure management, virtualization management, container platform management, service management and user management. - we’ve realized log management system in some companies with ELK/EFK(Elasticsearch, Logstash/Fluentd, Kibana) stack.

With this, can create bar, line and scatter plots, or pie charts and maps on top of large volumes of data. Log management systems, we’ve developed, are contains several figures and data tables according time line.
