This plugin gathers health status metrics from one or more [MarkLogic][marklogic]
hosts.

⭐ Telegraf v1.12.0
🏷️ server

## Global configuration options <!-- @/docs/includes/plugin_config.md -->

In addition to the plugin-specific configuration settings, plugins support
additional global and plugin configuration settings. These settings are used to
modify metrics, tags, and field or create aliases and configure ordering, etc.
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.

[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins

## Configuration

```toml @sample.conf
# Retrieves information on a specific host in a MarkLogic Cluster
[[inputs.marklogic]]
  ## Base URL of the MarkLogic HTTP Server.
  url = "http://localhost:8002"

  ## List of specific hostnames to retrieve information. At least (1) required.
  # hosts = ["hostname1", "hostname2"]

  ## Using HTTP Basic Authentication. Management API requires 'manage-user' role privileges
  # username = "myuser"
  # password = "mypassword"

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false
```
