“Cloud Monitoring”

Pengantar

Cloud Monitoring memberikan visibilitas ke kinerja, waktu aktif, dan kesehatan aplikasi yang didukung cloud secara keseluruhan. Cloud Monitoring mengumpulkan metrik, peristiwa, dan metadata dari Google Cloud, Amazon Web Services, probe uptime yang dihosting, instrumentasi aplikasi, dan berbagai komponen aplikasi umum termasuk Cassandra, Nginx, Server Web Apache, Elasticsearch, dan banyak lainnya. Cloud Monitoring menyerap data tersebut dan menghasilkan wawasan melalui dasbor, diagram, dan peringatan. Peringatan Cloud Monitoring membantu Anda berkolaborasi dengan berintegrasi dengan Slack, PagerDuty, HipChat, Campfire, dan banyak lagi.
