# Prometheus service discovery
# Supported service discovery configs
[vmagent](https://docs.victoriametrics.com/vmagent.html) and [single-node VictoriaMetrics](https://docs.victoriametrics.com/#how-to-scrape-prometheus-exporters-such-as-node-exporter) supports the following Prometheus-compatible service discovery options for Prometheus-compatible scrape targets in the file pointed by `-promscrape.config` command-line flag.
* `azure_sd_configs` is for scraping the targets registered in [Azure Cloud](https://azure.microsoft.com/en-us/). See [these docs](#azure_sd_configs).
* `consul_sd_configs` is for discovering and scraping targets registered in [Consul](https://www.consul.io/). See [these docs](#consul_sd_configs).
* `digitalocean_sd_configs` is for discovering and scraping targerts registered in [DigitalOcean](https://www.digitalocean.com/). See [these docs](#digitalocean_sd_configs).
* `dns_sd_configs` is for discovering and scraping targets from [DNS](https://it.wikipedia.org/wiki/Domain_Name_System) records (SRV, A and AAAA). See [these docs](#dns_sd_configs).
* `docker_sd_configs` is for discovering and scraping [Docker](https://www.docker.com/) targets. See [these docs](#docker_sd_configs).
* `dockerswarm_sd_configs` is for discovering and scraping [Docker Swarm](https://docs.docker.com/engine/swarm/) targets. See [these docs](#dockerswarm_sd_configs).
* `ec2_sd_configs` is for discovering and scraping [Amazon EC2](https://aws.amazon.com/ec2/) targets. See [these docs](#ec2_sd_configs).
* `eureka_sd_configs` is for discovering and scraping targets registered in [Netflix Eureka](https://github.com/Netflix/eureka). See [these docs](#eureka_sd_configs).
* `file_sd_configs` is for scraping targets defined in external files (aka file-based service discovery). See [these docs](#file_sd_configs).
* `gce_sd_configs` is for discovering and scraping [Google Compute Engine](https://cloud.google.com/compute) targets. See [these docs](#gce_sd_configs).
* `http_sd_configs` is for discovering and scraping targerts provided by external http-based service discovery. See [these docs](#http_sd_configs).
* `kubernetes_sd_configs` is for discovering and scraping [Kubernetes](https://kubernetes.io/) targets. See [these docs](#kubernetes_sd_configs).

* `yandexcloud_sd_configs` is for discoverying and scraping [Yandex Cloud](https://cloud.yandex.com/en/) targets. See [these docs](#yandexcloud_sd_configs).
Note that the `refresh_interval` option isn't supported for these scrape configs. Use the corresponding `-promscrape.*CheckInterval`
command-line flag instead. For example, `-promscrape.consulSDCheckInterval=60s` sets `refresh_interval` for all the `consul_sd_configs`
entries to 60s. Run `vmagent -help` or `victoria-metrics -help` in order to see default values for the `-promscrape.*CheckInterval` flags.
Please file feature requests to [our issue tracker](https://github.com/VictoriaMetrics/VictoriaMetrics/issues) if you need other service discovery mechanisms to be supported by VictoriaMetrics and `vmagent`.

## file_sd_configs
File-based service discovery reads a set of files with lists of targets to scrape.
Scrape targets are automatically updated when the underlying files are changed with the interval
Configuration example:
```yaml

file_sd_configs:
# files must contain a list of file patterns for files with scrape targets.
# The last path segment can contain `*`, which matches any number of chars in file name.
- files:

- "another/path.json"
```
Files must contain a list of static configs in one of the following formats:
* JSON:
```json
[
{
"targets": ["<host>", ... ],
"labels": {
"<labelname>": "<labelvalue>",
...,
}
},
...
]
```
* YAML:
```yaml
- targets: ["<host>", ... ]
labels:

...
...
```
The following meta labels are available on discovered targets during [relabeling](https://docs.victoriametrics.com/vmagent.html#relabeling):

Credentials are discovered by looking in the following places, preferring the first location found:
1. a JSON file specified by the `GOOGLE_APPLICATION_CREDENTIALS` environment variable
2. a JSON file in the well-known path `$HOME/.config/gcloud/application_default_credentials.json`
3. fetched from the GCE metadata server

## http_sd_configs
HTTP-based service discovery fetches targets from the specified `url`.
Configuration example:
```yaml
scrape_configs:
- job_name: http
http_sd_configs:
# url must contain the URL from which the targets are fetched.
- url: "http://..."
# Additional HTTP API client options can be specified here.
# See https://docs.victoriametrics.com/sd_configs.html#http-api-client-options
```
The service at `url` must return JSON response in the following format:
```json
[
{
"targets": [ "<host>", ... ],
"labels": {
"<labelname>": "<labelvalue>",
...
}
},
...
]
```
The `url` is queried periodically with the interval specified in `-promscrape.httpSDCheckInterval` command-line flag.
Discovery errors are tracked in `promscrape_discovery_http_errors_total` metric.
The following meta labels are available on discovered targets during [relabeling](https://docs.victoriametrics.com/vmagent.html#relabeling):
* `__meta_url`: the URL from which the target was extracted

# If honor_labels is set to "true", label conflicts are resolved by keeping label
# values from the scraped data and ignoring the conflicting server-side labels.
#
# If honor_labels is set to "false", label conflicts are resolved by renaming
# conflicting labels in the scraped data to "exported_<original-label>" (for
# example "exported_instance", "exported_job") and then attaching server-side
# labels.
#
# Setting honor_labels to "true" is useful for use cases such as federation and

# preserved.
#
# By default honor_labels is set to false for security and consistency reasons.
# honor_labels: <boolean>
# honor_timestamps controls whether to respect the timestamps present in scraped data.
#
