The examples provided in this document assume that you will be using Netdata as +a metrics endpoint, but the concepts apply as well to the remote write API method. + +### Understanding Netdata metrics + +#### Charts + +Each chart in Netdata has several properties (common to all its metrics): + +- `chart_id` - uniquely identifies a chart. + +- `chart_name` - a more human friendly name for `chart_id`, also unique. + +- `context` - this is the template of the chart. All disk I/O charts have the same context, all mysql requests charts + have the same context, etc. This is used for alert templates to match all the charts they should be attached to. + +- `family` groups a set of charts together. It is used as the submenu of the dashboard. + +- `units` is the units for all the metrics attached to the chart. + +#### Dimensions + +Then each Netdata chart contains metrics called `dimensions`. All the dimensions of a chart have the same units of +measurement, and are contextually in the same category (ie. the metrics for disk bandwidth are `read` and `write` and +they are both in the same chart). + +### Netdata data source + +Netdata can send metrics to Prometheus from 3 data sources: + +- `as collected` or `raw` - this data source sends the metrics to Prometheus as they are collected. No conversion is + done by Netdata. The latest value for each metric is just given to Prometheus. This is the most preferred method by + Prometheus, but it is also the harder to work with. To work with this data source, you will need to understand how + to get meaningful values out of them. + + The format of the metrics is: `CONTEXT{chart="CHART",family="FAMILY",dimension="DIMENSION"}`. + + If the metric is a counter (`incremental` in Netdata lingo), `_total` is appended the context. + + Unlike Prometheus, Netdata allows each dimension of a chart to have a different algorithm and conversion constants + (`multiplier` and `divisor`). In this case, that the dimensions of a charts are heterogeneous, Netdata will use this + format: `CONTEXT_DIMENSION{chart="CHART",family="FAMILY"}` + +- `average` - this data source uses the Netdata database to send the metrics to Prometheus as they are presented on + the Netdata dashboard. So, all the metrics are sent as gauges, at the units they are presented in the Netdata + dashboard charts. This is the easiest to work with. + + The format of the metrics is: `CONTEXT_UNITS_average{chart="CHART",family="FAMILY",dimension="DIMENSION"}`. + + When this source is used, Netdata keeps track of the last access time for each Prometheus server fetching the + metrics. This last access time is used at the subsequent queries of the same Prometheus server to identify the + time-frame the `average` will be calculated. + + So, no matter how frequently Prometheus scrapes Netdata, it will get all the database data. + To identify each Prometheus server, Netdata uses by default the IP of the client fetching the metrics. + + If there are multiple Prometheus servers fetching data from the same Netdata, using the same IP, each Prometheus + server can append `server=NAME` to the URL. Netdata will use this `NAME` to uniquely identify the Prometheus server. + +- `sum` or `volume`, is like `average` but instead of averaging the values, it sums them. + + The format of the metrics is: `CONTEXT_UNITS_sum{chart="CHART",family="FAMILY",dimension="DIMENSION"}`. All the + other operations are the same with `average`. + + To change the data source to `sum` or `as-collected` you need to provide the `source` parameter in the request URL. + e.g.: `http://your.netdata.ip:19999/api/v1/allmetrics?format=prometheus&help=yes&source=as-collected` + + Keep in mind that early versions of Netdata were sending the metrics as: `CHART_DIMENSION{}`. + +### Querying Metrics + +Fetch with your web browser this URL: + +`http://your.netdata.ip:19999/api/v1/allmetrics?format=prometheus&help=yes` + +_(replace `your.netdata.ip` with the ip or hostname of your Netdata server)_ + +Netdata will respond with all the metrics it sends to Prometheus. + +If you search that page for `"system.cpu"` you will find all the metrics Netdata is exporting to Prometheus for this +chart. `system.cpu` is the chart name on the Netdata dashboard (on the Netdata dashboard all charts have a text heading +such as : `Total CPU utilization (system.cpu)`.

Usually IDs are unique identifiers as read by the system and +names are human friendly labels (also unique). + +Most charts and metrics have the same ID and name, but in several cases they are different: disks with device-mapper, +interrupts, QoS classes, statsd synthetic charts, etc. + +The default is controlled in `exporting.conf`: + +```conf +[prometheus:exporter] + send names instead of ids = yes | no +``` + +You can overwrite it from Prometheus, by appending to the URL: + +- `&names=no` to get IDs (the old behaviour) +- `&names=yes` to get names + +### Filtering metrics sent to Prometheus + +Netdata can filter the metrics it sends to Prometheus with this setting: + +```conf +[prometheus:exporter] + send charts matching = * +``` + +This settings accepts a space separated list +of [simple patterns](/src/libnetdata/simple_pattern/README.md) to match the +**charts** to be sent to Prometheus. Each pattern can use `*` as wildcard, any number of times (e.g `*a*b*c*` is valid). +Patterns starting with `!` give a negative match (e.g `!*.bad users.* groups.*` will send all the users and groups +except `bad` user and `bad` group). The order is important: the first match (positive or negative) left to right, is +used. + +### Changing the prefix of Netdata metrics + +Netdata sends all metrics prefixed with `netdata_`. You can change this in `netdata.conf`, like this: + +```conf +[prometheus:exporter] + prefix = netdata +``` + +It can also be changed from the URL, by appending `&prefix=netdata`. + +### Metric Units + +The default source `average` adds the unit of measurement to the name of each metric (e.g. `_KiB_persec`). To hide the +units and get the same metric names as with the other sources, append to the URL `&hideunits=yes`. + +The units were standardized in v1.12, with the effect of changing the metric names. To get the metric names as they were +before v1.12, append to the URL `&oldunits=yes` + +### Accuracy of `average` and `sum` data sources + +When the data source is set to `average` or `sum`, Netdata remembers the last access of each client accessing Prometheus +metrics and uses this last access time to respond with the `average` or `sum` of all the entries in the database since +that. This means that Prometheus servers are not losing data when they access Netdata with data source = `average` or +`sum`. + +To uniquely identify each Prometheus server, Netdata uses the IP of the client accessing the metrics. If however the IP +is not good enough for identifying a single Prometheus server (e.g. when Prometheus servers are accessing Netdata +through a web proxy, or when multiple Prometheus servers are NATed to a single IP), each Prometheus may append +`&server=NAME` to the URL. This `NAME` is used by Netdata to uniquely identify each Prometheus server and keep track of +its last access time. + +## Configure Prometheus to scrape Netdata metrics + +The following `prometheus.yml` file will scrape all netdata metrics "as collected". + +Make sure to replace `your.netdata.ip` with the IP or hostname of the host running Netdata. + +```yaml +# my global config +global: + scrape_interval: 5s # Set the scrape interval to every 5 seconds.
