Catatan penggunaan
Prinsip-prinsip berikut menjelaskan cara penyaringan pesan:
-
Event yang sesuai harus mencakup semua bidang yang tercantum dalam pola event, dan struktur bersarang bidang dalam event tersebut harus identik dengan struktur dalam pola event.
-
Pencocokan dilakukan secara eksak untuk setiap karakter dalam pola event. Semua karakter bersifat case-sensitive. EventBridge tidak mengubah string selama proses pencocokan.
-
Semua nilai dalam event yang sesuai harus dalam format JSON, termasuk nilai numerik, string yang diapit tanda kutip ganda (""), serta kata kunci tanpa tanda kutip seperti true, false, dan null.
-
Pola event mendukung operator logika OR. Anda dapat menggunakan operator logika AND untuk menentukan keys dalam pola event, dan operator logika OR untuk menentukan nilai key dalam array.
Pencocokan event berdasarkan nilai bidang
Anda dapat menentukan nilai bidang tertentu sebagai kondisi pencocokan. Pada contoh berikut, hanya event yang nilai bidang source-nya menunjukkan Object Storage Service (OSS) yang dicocokkan dan disaring. Tabel berikut menjelaskan proses pengiriman event dari sumber event dan penyaringannya oleh pola event.

Pencocokan event berdasarkan inklusi nilai bidang
Anda dapat menentukan nilai bidang yang ingin disertakan dalam pencocokan event. Bagian berikut menjelaskan dua contoh. Pada Contoh 1, hanya event yang nilai bidang type-nya mengandung Normal yang dicocokkan dan disaring. Pada Contoh 2, hanya event yang nilai bidang type-nya mengandung Normal atau Error yang dicocokkan dan disaring. Tabel berikut menjelaskan proses pengiriman event dari sumber event dan penyaringannya oleh pola event.
Contoh 1: Cocokkan event yang nilai bidang "type" mengandung "Normal"

Pencocokan event berdasarkan pengecualian nilai bidang
Anda dapat menentukan nilai bidang yang ingin dikecualikan dari pencocokan event. Gunakan bidang anything-but untuk mengecualikan string dan nilai numerik. Pada contoh berikut, hanya event yang nilai bidang state-nya bukan initializing dan nilai bidang x-limit-nya bukan 123 yang dicocokkan dan disaring. Tabel berikut menjelaskan proses pengiriman event dari sumber event dan penyaringannya oleh pola event.
Pola berikut menggunakan bidang anything-but untuk mengecualikan satu string dan satu nilai numerik.

Pencocokan event berdasarkan nilai numerik atau rentang
Anda dapat menentukan nilai numerik atau rentang untuk suatu bidang sebagai kondisi pencocokan. Pada contoh berikut, hanya event yang nilai bidang c-count-nya lebih besar dari 0 dan kurang dari atau sama dengan 5, nilai bidang d-count-nya kurang dari 10, dan nilai bidang x-limit-nya 301,8 yang dicocokkan dan disaring.

Penting
Pencocokan nilai numerik hanya berlaku jika nilai tersebut dalam format JSON dan berada dalam rentang -1,0e9 hingga +1,0e9. Nilai numerik ini akurat hingga 15 digit dan enam tempat desimal.
Pencocokan event berdasarkan alamat IP
Anda dapat menentukan alamat IP dengan menggunakan bidang dalam parameter data sebagai kondisi pencocokan. Pada contoh berikut, hanya event yang nilai bidang source-ip-nya 10.0.0.0/24 yang dicocokkan dan disaring.

Pencocokan event berdasarkan kondisi gabungan
Anda dapat menggabungkan beberapa aturan filter sebagai kondisi pencocokan untuk mencocokkan dan menyaring event secara tepat. Pada contoh berikut, pencocokan berdasarkan awalan, pencocokan pengecualian, pencocokan alamat IP, dan pencocokan nilai numerik digabungkan.

Pencocokan event berdasarkan array
Nilai setiap bidang dalam pola event adalah array yang berisi satu atau beberapa nilai. Jika salah satu nilai dalam array tersebut cocok dengan nilai dalam event, maka event tersebut dicocokkan dan disaring. Jika nilai dalam event juga berupa array, dan irisan antara array dalam event dengan array dalam pola event bukan himpunan kosong, maka event tersebut dicocokkan dan disaring. Tabel berikut menjelaskan proses pengiriman event dari sumber event dan penyaringannya oleh pola event.

Catatan
Nilai null berbeda dengan string kosong. Jika Anda menggunakan pola event untuk mencocokkan string kosong, nilai null tidak akan dicocokkan.
Pencocokan event berdasarkan keberadaan atau ketiadaan bidang
Anda dapat menentukan keberadaan atau ketiadaan suatu bidang dalam parameter data sebagai kondisi pencocokan. Pada contoh berikut, hanya event yang tidak memiliki bidang state yang dicocokkan dan disaring. Tabel berikut menjelaskan proses pengiriman event dari sumber event dan penyaringannya oleh pola event.
