`APISIX` Metric¶

APISIX components can expose metrics capabilities externally by accessing curl http://127.0.0.1:9091/apisix/prometheus/metrics You can obtain relevant metric information.

...

DataKit configure¶

Because APISIX can expose metrics URL directly, it can be collected directly through prom collector.

[[inputs.prom]]
  ## Exporter URLs.
  urls = ["http://localhost:9091/apisix/prometheus/metrics"]

Metric¶

Tags	Describe
bandwidth	Total amount of traffic (ingress and egress) flowing through `APISIX`. Total bandwidth of a service can also be obtained
etcd_modify_indexes	etcd modify indexes
etcd_reachable	A gauge type representing whether etcd can be reached by `APISIX`. A value of 1 represents reachable and 0 represents unreachable.
http_latency_bucket	Histogram of the request time per service
http_latency_count	Total count of the request time per service
http_latency_sum	Sum of the request time per service
http_requests_total	Total count of http requests
http_status	http status
nginx_http_current_connections	Nginx connection metrics like active, reading, writing, and number of accepted connections.
nginx_metric_errors_total	nginx error count
node_info	Information about the `APISIX` node.
shared_dict_capacity_bytes	The capacity space of all nginx.shared.DICT in `APISIX`.
shared_dict_free_space_bytes	The free space of all nginx.shared.DICT in `APISIX`.
