The configuration of prometheus isn't really of interest, because it's json_exporter that's returning the error.
Scrape the exporter by hand: curl -vg 'http://localhost:7979/probe?target=http:%2f%2flocalhost%3a9015%2fservices%2fv2%2fmpoints%2fE_TIP5%2fstatistics' I suspect you'll see the 503 error there too, but you may get a more detailed error message that may help understand what's going on. Also try scraping the JSON target directly: curl -vh 'http://localhost:9015/services/v2/mpoints/E_TIP5/statistics' If the latter doesn't work, or doesn't return JSON, then obviously the former won't work either. Likely problems are: - the .../statistics endpoint isn't working or isn't returning JSON - the configuration of json_exporter is bad On Tuesday, 19 April 2022 at 03:24:40 UTC+1 [email protected] wrote: > > Hi, > I'm getting below error on prometheus console log while scraping metrics > from json_exporter > <https://github.com/prometheus-community/json_exporter/tree/c487740bb83f5b2a682d99161cbe8e4209ba4b2e>. > > Target endpoint is available and able to get response with curl using basic > authentication. > > ts=2022-04-18T20:58:07.156Z caller=scrape.go:1292 level=debug > component="scrape manager" scrape_pool=json target=" > http://localhost:7979/probe?target=http%3A%2F%2Flocalhost%3A9015%2Fservices%2Fv2%2Fmpoints%2FE_TIP5%2Fstatistics"; > > msg="Scrape failed" err="server returned HTTP status 503 Service > Unavailable" > > > Here is the prometheus.yaml > > scrape_configs: > > ## gather metrics of prometheus itself > - job_name: prometheus > static_configs: > - targets: > - localhost:9090 > > ## gather the metrics of json_exporter application itself > - job_name: json_exporter > static_configs: > - targets: > - localhost:7979 ## Location of the json exporter's real <hostname>:<port> > > ## gather the metrics from third party json sources, via the json exporter > - job_name: json > scrape_interval: 15s > scrape_timeout: 10s > metrics_path: /probe > basic_auth: > username: XXXXXX > password: XXXXX > static_configs: > - targets: ['http://localhost:9015/services/v2/mpoints/E_TIP5/statistics'] > relabel_configs: > - source_labels: [__address__] > target_label: __param_target > - source_labels: [__param_target] > target_label: instance > - target_label: __address__ > replacement: localhost:7979 ## Location of the json exporter's real > <hostname>:<port> > -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
