json_exporter prometheus debug

 JSON url to convert : http://json_url/foobar.json

json_exporter running locally : localhost:7979 or json_exporter:7979 

Status of the json_exporter, does NOT contain the metrics from the targets, only related to the process itself (useful to know if it's up or not for example).

 localhost:7979/metrics

Check the result of a JSON URL to be converted / aka. what prometheus should scrape

curl http://json_url/foobar.json => JSON (original)

curl localhost:7979/probe?target=https://json_url/foobar.json => openmetrics converted by json_exporter

Other useful commands :

* edit, restart, wait, check json_exporter output

sudo vi /etc/json_exporter/config.yml && sudo systemctl restart json_exporter && sleep 5 && curl http://localhost:7979/probe?target=http://json_url/foobar.json

* edit, check and restart prometheus : 

sudo vi /etc/prometheus/prometheus.yml && sudo promtool check config /etc/prometheus/prometheus.yml && sudo systemctl restart prometheus.service

Service Level metrics

•  SLO : Service Level Objective

Common examples of metrics that can be associated with SLOs are disaster recovery time, application availability, live communication response time, first call resolution rate and application maintenance.

• SLI : Service Level Indicator

SLI = [ good event / valid event ] * 100%

request / response : Availability, Latency, Quality

Data Processing : Coverage, Correctness, Freshness, Throughput

• SLA : Service level agreements

usually external metrics (i.e. : end service KO time)
