Typesense memiliki endpoint metrics.json untuk melakukan monitoring dengan data yang dihasilkan format JSON.
{Kita dapat melakukan monitoring endpoint tersebut menggunakan Prometheus.

}
1. Install Prometheus
export RELEASE="2.33.3"
Cek versi terakhir di Official Page
wget https://github.com/prometheus/prometheus/releases/download/v${RELEASE}/prometheus-${RELEASE}.linux-amd64.tar.gz
tar xvf prometheus-${RELEASE}.linux-amd64.tar.gz
Masuk ke direktori Prometheus yang baru di ekstrak
cd prometheus-${RELEASE}.linux-amd64/
2. Install json_exporter
Karena metrics dari Typesense menggunakan format JSON, maka harus menggunakan service lagi untuk melakukan konversi dari JSON ke metric Prometheus.
git clone https://github.com/prometheus-community/json_exporter.git
3. Install make
sudo apt install make
Make build
cd json_exporter
make build
Jika diperlukan, install go terlebih dahulu
sudo snap install go --classic
4. Buat file config.xml
nano config.yml

5. Jalankan json_exporter
./json_exporter --config.file config.yml
Untuk melakukan pengecekan, coba akses
curl http://[IP ADDRESS JSON_EXPORTER]:7979/probe?target=http://[IP ADDRESS TYPESENSE]:8108/metrics.json
Seharusnya metrics Typesense sudah dikonversi menjadi metrics Prometheus.
6. Jalankan Prometheus
Langkah selanjutnya adalah konfigurasi Prometheus
Tambahkan job baru pada config
- job_name: 'typesense'
metrics_path: /probe
static_configs:
- targets:
- http://[IP TYPESENSE]:8108/metrics.json
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- source_labels: [__param_target]
target_label: instance
- target_label: __address__
replacement: localhost:7979
Jalankan Prometheus
./prometheus
Cek menggunakan browser di http://[IP PROMETHEUS]:9090/targets
