Metrics that will start having values, after Netdata is started, +will be detected and charts will be automatically added to the dashboard (a refresh of the dashboard is needed for them +to appear though). Use `yes` instead of `auto` in plugin configuration sections to enable these charts permanently. You +can also set the `enable zero metrics` option to `yes` in the `[global]` section which enables charts with zero metrics +for all internal Netdata plugins. ### External plugins External plugins will have only 2 options at `netdata.conf`: -| setting | default | info | -| :-----:|:-----:|:---| -| update every | the value of `[global].update every` setting|The frequency in seconds the plugin should collect values. For more information check the [performance guide](/docs/guides/configure/performance.md).| -| command options | _empty_ | Additional command line options to pass to the plugin.| - -External plugins that need additional configuration may support a dedicated file in `/etc/netdata`. Check their documentation. - -## Per-chart configuration - -In this area of `netdata.conf` you can find configuration options for individual charts. They appear in sections -following the pattern `[NAME]`. - -Using the settings and values under these sections, you can control all aspects of a specific chart. You can change its -title, make it appear higher in Netdata's [menu](/web/gui/README.md#metrics-menus), tweak its dimensions, and much more. - -To find the name of a given chart, and thus the name of its section in `netdata.conf`, look at the top-left corner of a -chart: - - - -Every per-chart configuration section has several common settings, which are listed in the table just below. Beneath -that is information about lines that begin with `dim`, which affect a chart's dimensions. - -| Setting | Function | -| :---------------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -| `history` | Override the `history` setting in the [[global] options](#global-section-options) for this particular chart. Should be less than or equal to the global `history` setting. | -| `enabled` | A boolean (`yes` or `no`) that explicitly enables or disables the chart in question. | -| `cache directory` | The directory where cache files for this plugin, if needed, are stored. | -| `chart type` | Defines what type of chart to display. It can be `line`, `area`, or `stacked`. If empty or missing, `line` will be used. | -| `type` | Uniquely identify which [metrics menu](/web/gui/README.md#metrics-menus) on the Netdata dashboard this chart should appear under. Some examples include `system` (**System**), `disk` (**Disks**), `net` (**Network Interfaces**), and `netdata` (**Netdata Monitoring**). | -| `family` | Change the chart's [family](/web/README.md#families) from its default. For example, you could force a disk space chart to collect metrics for family `sdb` instead of family `sda`. | -| `units` | Text for the label of the vertical axis of the chart. This means all dimensions should have the same unit of measurement. | -| `context` | Change the default [context](/web/README.md#contexts) of the chart. Changing this setting will affect what metrics and metrics the chart displays, and which alarms are attached to it. | -| `priority` | Define where the chart should appear on the Netdata dashboard. Lower values equal higher priority, so a priority of `1` will place the chart highest, while a priority of `9999999` would place the chart at the bottom of the Netdata dashboard. | -| `name` | The name of the chart that appears in the top-left corner, after the chart's title. You can also use this name when writing [health entities](/health/REFERENCE.md#health-entity-reference). | -| `title` | The text that appears above the chart in the Netdata dashboard. | - -### Dimension settings - -You may notice some settings that begin with `dim` beneath the ones defined in the table above. These settings determine -which dimensions appear on the given chart and how Netdata calculates them. - -Each dimension setting has the following structure: `dim [DIMENSION ID] [OPTION] = [VALUE]`. The available options are `name`, `algorithm`, `multiplier`, and `divisor`. - -| Setting | Function | -| :----------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | -| `name` | The name of the dimension as it will appear in the legend of the chart. If left empty, or is missing, Netdata will use the `[DIMENSION ID]` instead. | -| `algorithm` | Can be `absolute`, `incremental`, `percentage-of-absolute-row`, or `percentage-of-incremental-row`. If this setting is empty, invalid, or missing, Netdata will use `absolute`. See the list beneath this table for descriptions of what each algorithm does. | -| `multiplier` | An integer value by which to multiply the collected value. If empty or missing, Netdata will use `1`. This setting is often used with the value `1024` to convert metabytes to kilobytes, kilobytes to bytes, and so on. | -| `divisor` | An integer value by which to divide the collected value. If empty or missing, Netdata will use `1`. This setting is often used with the value `1024` to convert bytes to kilobytes, kilobytes to megabytes, and so on. | - -Here are the options for the `algorithm` setting: - -- `absolute`: The value is drawn as-is (interpolated to second boundary). -- `incremental`: To be used when the value always increases over time, such as the I/O on a disk. Netdata takes the - difference between the current metric and the past metric to calculate a per-second figure. -- `percentage-of-absolute-row`: The % of this value compared to the total of all dimensions. -- `percentage-of-incremental-row`: The % of this value compared to the incremental total of all dimensions. - -For example, the `system.io` chart has the following default settings: - -```conf - # dim in name = in - # dim in algorithm = incremental - # dim in multiplier = 1 - # dim in divisor = 1 - # dim out name = out - # dim out algorithm = incremental - # dim out multiplier = -1 - # dim out divisor = 1 -``` - -These `dim` settings produce two dimensions, `in` and `out`, both of which use the `incremental` algorithm. By -multiplying the value of `out` by -1, Netdata creates the negative values seen in the following area chart: - - +| setting | default | info | +|:---------------:|:--------------------------------------------:|:------------------------------------------------------------------------------------------------------------------------------------------------------| +| update every | the value of `[global].update every` setting | The frequency in seconds the plugin should collect values.
