## Monitoring
VictoriaMetrics exports internal metrics in Prometheus exposition format at `/metrics` page.
These metrics can be scraped via [vmagent](https://docs.victoriametrics.com/vmagent.html) or Prometheus.
These metrics can be scraped via [vmagent](https://docs.victoriametrics.com/vmagent.html) or any other Prometheus-compatible scraper.
If you use Google Cloud Managed Prometheus for scraping metrics from VictoriaMetrics components, then pass `-metrics.exposeMetadata`
command-line to them, so they add `TYPE` and `HELP` comments per each exposed metric at `/metrics` page.
See [these docs](https://cloud.google.com/stackdriver/docs/managed-prometheus/troubleshooting#missing-metric-type) for details.
Alternatively, single-node VictoriaMetrics can self-scrape the metrics when `-selfScrapeInterval` command-line flag is
set to duration greater than 0. For example, `-selfScrapeInterval=10s` would enable self-scraping of `/metrics` page
with 10 seconds interval.
_Please note, never use loadbalancer address for scraping metrics. All monitored components should be scraped directly by their address._
