Anda dapat melihat metrik Replikasi Asinkron berikut di Cloud Monitoring:
Metrik
Deskripsi
Jumlah byte yang dikirim replikasi asinkron (disk/async_replication/sent_bytes_count)
Jumlah delta byte yang dikirim melalui jaringan lintas region.
Waktu replikasi asinkron sejak replikasi terakhir (disk/async_replication/time_since_last_replication)
Jumlah detik sejak replikasi terakhir selesai, juga dikenal sebagai toleransi durasi kehilangan data (RPO).
Memantau jumlah byte yang dikirim
Gunakan metrik Jumlah byte yang dikirim replikasi asinkron untuk membuat grafik jumlah rata-rata byte yang dikirim, yang diambil sampelnya setiap menit. Jumlah byte yang dikirim mewakili data yang ditulis oleh workload Anda ke block storage, yang memengaruhi kecepatan replikasi.
Di konsol Google Cloud , buka halaman
Cloud Monitoring > Metrics Explorer.
Pilih daftar kategori metrik aktif Disk, lalu pilih Async replication sent bytes count (disk/async_replication/sent_bytes_count).
Klik Apply.
Pada menu Transform, pilih salah satu dari opsi berikut:
Untuk melihat jumlah total byte yang dikirim, pilih None.
Untuk melihat jumlah byte yang dikirim per detik, pilih Rate.
Di bagian Filters, lakukan tindakan berikut:
Klik Add filter.
Klik di dalam kotak Label untuk melihat daftar label yang tersedia. Di bagian judul Resource labels, pilih project_id. Biarkan
nilai Perbandingan ditetapkan ke = (equals). Di kolom Nilai, ketik atau
pilih project ID Anda. Klik Done.
Klik Add filter.
Di kotak Label, pilih disk_id. Biarkan nilai Comparison ditetapkan ke = (equals). Di kolom Value, ketik atau pilih ID dari disk utama yang direplikasi.
Klik Done.
Klik More options.
Di menu Alignment function, pilih fungsi penyelarasan. Fungsi penyelarasan Mean menunjukkan jumlah rata-rata byte yang dikirim per menit, sedangkan fungsi penyelarasan Max menunjukkan jumlah byte tertinggi yang dikirim per menit.
Di menu Min alignment period, pilih periode penyelarasan. Periode penyelarasan harus minimal satu menit.
Memantau RPO
Gunakan metrik Waktu replikasi asinkron sejak replikasi terakhir untuk membuat grafik jumlah detik sejak replikasi terakhir dilakukan (RPO).
Di konsol Google Cloud , buka halaman
Cloud Monitoring > Metrics Explorer.
Pilih daftar kategori metrik aktif Disk, lalu pilih Async replication time since last replication (disk/async_replication/time_since_last_replication).
Klik Apply.
Di bagian Filters, tambahkan filter untuk project ID dan disk ID Anda:
Klik Add filter.
Klik di dalam kotak Label untuk melihat daftar label yang tersedia. Di bagian judul Resource labels, pilih project_id. Biarkan
nilai Perbandingan ditetapkan ke = (equals). Di kolom Nilai, ketik atau
pilih project ID Anda. Klik Done.
Klik Add filter.
Di kotak Label, pilih disk_id. Biarkan nilai Comparison ditetapkan ke = (equals). Di kolom Value, ketik atau pilih ID dari disk utama yang direplikasi.
Klik Done.
Klik More options.
Di menu Alignment function, pilih fungsi penyelarasan. Fungsi penyelarasan Mean menunjukkan jumlah rata-rata detik sejak replikasi terakhir dilakukan, sedangkan fungsi penyelarasan Max menunjukkan jumlah detik terbanyak sejak replikasi terakhir dilakukan.
Di menu Min alignment period, pilih periode penyelarasan. Periode penyelarasan harus minimal satu menit.
Opsional: Simpan diagram.
