Metrics are gathered by periodically sending HTTP requests to . This collector is supported on all platforms. This collector supports collecting metrics from multiple instances of this integration, including remote instances. By default, it detects instances running on the local host by trying to connect to known ports that are . The full list of endpoints is available in the collector's . The default configuration for this integration does not impose any limits on data collection. The default configuration for this integration is not expected to impose a significant performance impact on the system. This collector has built-in grouping logic based on the . | Metric | Chart | Dimension(s) | Algorithm | ||-|-|-| | Gauge | for each label set | one, the metric name | absolute | | Counter | for each label set | one, the metric name | incremental | | Summary (quantiles) | for each label set (excluding 'quantile') | for each quantile | absolute | | Summary (sum and count) | for each label set | the metric name | incremental | | Histogram (buckets) | for each label set (excluding 'le') | for each bucket | incremental | | Histogram (sum and count) | for each label set | the metric name | incremental | Untyped metrics (have no '# TYPE') processing: As Counter or Gauge depending on pattern match when 'fallback_type' is used. As Counter if it has suffix '_total'. As Summary if it has 'quantile' label. As Histogram if it has 'le' label. The rest are ignored. There are no alerts configured by default for this integration. Install by following the instructions mentioned in the exporter README. The configuration file name for this integration is `go.d/prometheus.conf`. You can edit the configuration file using the `edit-config` script from the Netdata . ```bash cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata sudo ./edit-config go.d/prometheus.conf ``` The following options can be defined globally: updateevery, autodetectionretry. <details><summary>Config options</summary> | Name | Description | Default | Required | |:-|:--|:-|:--:| | update_every | Data collection frequency. | 10 | no | | autodetection_retry | Recheck interval in seconds. Zero means no recheck will be scheduled. | 0 | no | | url | Server URL. | | yes | | selector | Time series selector (filter). | | no | | fallback_type | Time series selector (filter). | | no | | maxtimeseries | Global time series limit. If an endpoint returns number of time series > limit the data is not processed. | 2000 | no | | maxtimeseriespermetric | Time series per metric (metric name)

Metrics with number of time series > limit are skipped. | 200 | no | | timeout | HTTP request timeout. | 10 | no | | username | Username for basic HTTP authentication. | | no | | password | Password for basic HTTP authentication. | | no | | proxy_url | Proxy URL. | | no | | proxy_username | Username for proxy basic HTTP authentication. | | no | | proxy_password | Password for proxy basic HTTP authentication. | | no | | method | HTTP request method. | GET | no | | body | HTTP request body. | | no | | headers | HTTP request headers. | | no | | notfollowredirects | Redirect handling policy. Controls whether the client follows redirects. | no | no | | tlsskipverify | Server certificate chain and hostname validation policy. Controls whether the client performs this check. | no | no | | tls_ca | Certification authority that the client uses when verifying the server's certificates. | | no | | tls_cert | Client TLS certificate. | | no | | tls_key | Client TLS key. | | no | This option allows you to filter out unwanted time series. Only metrics matching the selector will be collected. Logic: (pattern1 OR pattern2) AND !(pattern3 or pattern4) Pattern syntax: . Option syntax: ```yaml selector: allow: pattern1 pattern2 deny: pattern3 pattern4 ``` This option allows you to process Untyped metrics as Counter or Gauge instead of ignoring them. Metric name pattern syntax: . Option syntax: ```yaml fallback_type: counter: metricnamepattern1 metricnamepattern2 gauge: metricnamepattern3 metricnamepattern4 ``` </details> Note: Change the port of the monitored application on which it provides metrics. A basic example configuration. ```yaml jobs: name: local url: http://127.0.0.1:9090/metrics ``` An example configuration to read metrics from a file. <details><summary>Config</summary> ```yaml jobs: name: myapp url: file:///opt/metrics/myapp/metrics.txt ``` </details> Note: Change the port of the monitored application on which it provides metrics.

The output should give you clues as to why the collector isn't working. Navigate to the `plugins.d` directory, usually at `/usr/libexec/netdata/plugins.d/`. If that's not the case on your system, open `netdata.conf` and look for the `plugins` setting under `[directories]`. ```bash cd /usr/libexec/netdata/plugins.d/ ``` Switch to the `netdata` user. ```bash sudo -u netdata -s ``` Run the `go.d.plugin` to debug the collector: ```bash ./go.d.plugin -d -m prometheus ```
