This collector is supported on all platforms. This collector supports collecting metrics from multiple instances of this integration, including remote instances. This integration doesn't support auto-detection. 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. Metrics grouped by scope. The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels. These metrics refer to the entire monitored application. This scope has no labels. Metrics: | Metric | Dimensions | Unit | |:|:-|:-| | dockerhub.pulls_sum | sum | pulls | | dockerhub.pulls | a dimension per repository | pulls | | dockerhub.pulls_rate | a dimension per repository | pulls/s | | dockerhub.stars | a dimension per repository | stars | | dockerhub.status | a dimension per repository | status | | dockerhub.last_updated | a dimension per repository | seconds | There are no alerts configured by default for this integration. No action required. The configuration file name for this integration is `go.d/dockerhub.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/dockerhub.conf ``` The following options can be defined globally: updateevery, autodetectionretry. <details><summary>Config options</summary> | Name | Description | Default | Required | |:-|:--|:-|:--:| | update_every | Data collection frequency. | 1 | no | | autodetection_retry | Recheck interval in

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 dockerhub ```
