Memantau Server Virtuozzo Hybrid dengan Prometheus

Pengguna Virtuozzo dan OpenVZ biasanya bekerja dengan banyak mesin yang digunakan yang menjalankan perangkat lunak kami. Oleh karena itu, logis bagi mereka untuk meluncurkan pemantauan terpusat dari seluruh armada server tersebut. Dan hari ini kami akan memberi tahu Anda cara menggunakan layanan pemantauan bawaan dari Virtuozzo Hybrid Infrastructure berdasarkan Prometheus untuk ini.
