How to get Fluint-bit logs are get in the Grafana without install Prometheus?

[Ommkwn2001]

I install first of all Fluint-bit and i changes on the value.yaml of Fluint-bit.

And I install Grafana and i login in Grafana dashboard successfully and than i first of all add Data Source in Grafana.

The Data Source is "Prometheus".

And than i pass this url "http://fluent-bit.default.svc.cluster.local:2020/api/v1/metrics/prometheus" And i try with this url also "http://fluent-bit.default.svc.cluster.local:2020/api/v1/metrics".

And i choose HTTP method : POST And i click on the Save & Test And i click on "Add new dashboard" and click on "Add Visualization" and select Data Source "Prometheus".

And i try this query "rate(fluentbit_input_record_total{name="systemd."}[1m]) " but there are no any graphs are get

My Fluint-Bit value.yaml is :

`# Default values for fluent-bit.

I want to get Fluint-bit logs are get in the Grafana with CPU usage and Memory usage graphs without install Prometheus

And when i try this url "http://fluent-bit.default.svc.cluster.local:2020/api/v1/metrics/prometheus" there are get same error like this "ReadObject: expect { or , or } or n, but found #, error found in #1 byte of ...|# HELP flue|..., bigger context ...|# HELP fluentbit_filter_add_record_total Fluentbit |... - There was an error returned querying the Prometheus API."
