prometheus.exporter.memcached
The prometheus.exporter.memcached
component embeds
memcached_exporter for collecting metrics from a Memcached server.
Usage
prometheus.exporter.memcached "LABEL" {
}
Arguments
The following arguments are supported:
Name | Type | Description | Default | Required |
---|---|---|---|---|
address | string | The Memcached server address. | "localhost:11211" | no |
timeout | duration | The timeout for connecting to the Memcached server. | "1s" | no |
Blocks
The prometheus.exporter.memcached
component does not support any blocks, and is configured
fully through arguments.
Exported fields
The following fields are exported and can be referenced by other components.
Name | Type | Description |
---|---|---|
targets | list(map(string)) | The targets that can be used to collect exporter metrics. |
For example, the targets
can either be passed to a discovery.relabel
component to rewrite the targets’ label sets, or to a prometheus.scrape
component that collects the exposed metrics.
The exported targets will use the configured in-memory traffic address specified by the run command.
Component health
prometheus.exporter.memcached
is only reported as unhealthy if given
an invalid configuration. In those cases, exported fields retain their last
healthy values.
Debug information
prometheus.exporter.memcached
does not expose any component-specific
debug information.
Debug metrics
prometheus.exporter.memcached
does not expose any component-specific
debug metrics.
Example
This example uses a prometheus.exporter.memcached
component to collect metrics from a Memcached
server running locally, and scrapes the metrics using a prometheus.scrape component:
prometheus.exporter.memcached "example" {
address = "localhost:13321"
timeout = "5s"
}
prometheus.scrape "example" {
targets = [prometheus.exporter.memcached.example.targets]
forward_to = [prometheus.remote_write.demo.receiver]
}
prometheus.remote_write "demo" {
endpoint {
url = PROMETHEUS_REMOTE_WRITE_URL
basic_auth {
username = USERNAME
password = PASSWORD
}
}
}
Replace the following:
PROMETHEUS_REMOTE_WRITE_URL
: The URL of the Prometheus remote_write-compatible server to send metrics to.USERNAME
: The username to use for authentication to the remote_write API.PASSWORD
: The password to use for authentication to the remote_write API.
