This document covers various output configurations for Telegraf for shipping data [via HTTP](https://docs.victoriametrics.com/#how-to-send-data-from-influxdb-compatible-agents-such-as-telegraf)
to VictoriaMetrics. All the options examples below can be combined to fit your use case.

To avoid storing Passwords in configuration files you can store as a key value pair in `/etc/default/telegraf` on Linux as follows
```
victoriametrics_url="https://victoriametrics_url"
victoriametrics_user="telegraf"
victoriametrics_password="password"
victoriametrics_token="my_token"
```
and they can be referenced in a Telegraf configuration file by prepending the variable name with `$`.
For example, `$victoriametrics_url` will be translated to `https://victoriametrics_url` if it is referenced in a Telegraf configuration using the values from `/etc/default/telegraf` in the values seen above.
Otherwise, please replace the variables below to fit your setup.

If you want to mimic this behavior on Windows please read [Influx Data's blog on storing variables in the registry](https://www.influxdata.com/blog/using-telegraf-on-windows/)
For shipping data in InfluxDB v2.x format refer to [Telegraf docs](https://github.com/influxdata/telegraf/blob/master/plugins/outputs/influxdb_v2/README.md).

## Minimum Configuration with no Authentication

```toml
[[outputs.influxdb]]
  urls = ["$victoriametrics_url"]
  database = "victoriametrics"
  skip_database_creation = true
  exclude_retention_policy_tag = true
  content_encoding = "gzip"
```

## HTTP Basic Authentication (Username and Password)

This is the same as the minimum configuration, but adds the `username` and `password` options:
```toml
[[outputs.influxdb]]
  urls = ["$victoriametrics_url"]
  username = "$victoriametrics_user"
  password = "$victoriametrics_password"
  database = "victoriametrics"
  skip_database_creation = true
  exclude_retention_policy_tag = true
  content_encoding = "gzip"
```

## Bearer Authentication (Token)

This is the same as the minimum configuration but adds the authorization header:
```
[[outputs.influxdb]]
  urls = ["$victoriametrics_url"]
  http_headers = {"Authorization" = "Bearer $victoriametrics_token"}
  database = "victoriametrics"
  skip_database_creation = true
  exclude_retention_policy_tag = true
  content_encoding = "gzip"
```

## Route certain metrics

If you only want to route certain metrics to VictoriaMetrics use the `namepass` option with a comma separated list of the measurements you wish to send to VictoriaMetrics:
```
[[outputs.influxdb]]
  urls = ["$victoriametrics_url"]
  username = "$victoriametrics_user"
  password = "$victoriametrics_password"
  database = "victoriametrics"
  skip_database_creation = true
  exclude_retention_policy_tag = true
  content_encoding = "gzip"
  namepass = ["cpu","disk","measurement1","measurement2"]
```

## Ignore TLS/SSL Certificate errors

This is the same as the minimum configuration but adds `insecure_skip_verify = true` to the configuration to ignore TLS certificate errors.
This is not recommended since it can allow sending metrics to a compromised site.

```
[[outputs.influxdb]]
  urls = ["$victoriametrics_url"]
  username = "$victoriametrics_user"
  password = "$victoriametrics_password"
  database = "victoriametrics"
  skip_database_creation = true
  exclude_retention_policy_tag = true
  content_encoding = "gzip"
  insecure_skip_verify = true
```
