Grafana'nın yetenekleri oldukça fazla ve görselliği ile yeterince beyenilen ve bir çok veriyi tek bir noktadan takip etmemizi sağlayan açık kaynak kodlu bir uygulamadır. Kurulum için debian işletim sistemi tercih edeceğim.
Arayüz ve pluginlerin yönetim için gerekli olan Grafana.
su - mkdir grafana cd grafana wget [url]https://dl.grafana.com/oss/release/grafana_9.3.6_amd64.deb[/url] dpkg -i grafana_9.3.6_amd64.deb systemctl status grafana-server.service
vim /etc/grafana/grafana.ini [server] protocol = http http_addr = 127.0.0.1 http_port = 3000 domain = 127.0.0.1 root_url = [url]http://127.0.0.1:3000[/url] [security] admin_user = admin admin_password = admin secret_key = xxxxx
Anlık akışları grafana için köprü kurmasına yardımcı olacak.
