# Docker Log Input Plugin
|
|
|
|
The docker log plugin uses the Docker Engine API to get logs on running
|
|
docker containers.
|
|
|
|
The docker plugin uses the [Official Docker Client](https://github.com/moby/moby/tree/master/client)
|
|
to gather logs from the [Engine API](https://docs.docker.com/engine/api/v1.24/).
|
|
Note: This plugin works only for containers with the `local` or `json-file` or `journald` logging driver.
|
|
### Configuration:
|
|
|
|
```toml
|
|
# Read metrics about docker containers
|
|
[[inputs.docker_log]]
|
|
## Docker Endpoint
|
|
## To use TCP, set endpoint = "tcp://[ip]:[port]"
|
|
## To use environment variables (ie, docker-machine), set endpoint = "ENV"
|
|
endpoint = "unix:///var/run/docker.sock"
|
|
|
|
## Containers to include and exclude. Collect all if empty. Globs accepted.
|
|
container_name_include = []
|
|
container_name_exclude = []
|
|
|
|
## Container states to include and exclude. Globs accepted.
|
|
## When empty only containers in the "running" state will be captured.
|
|
# container_state_include = []
|
|
# container_state_exclude = []
|
|
|
|
## docker labels to include and exclude as tags. Globs accepted.
|
|
## Note that an empty array for both will include all labels as tags
|
|
docker_label_include = []
|
|
docker_label_exclude = []
|
|
|
|
## 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
|
|
```
|
|
|
|
#### Environment Configuration
|
|
|
|
When using the `"ENV"` endpoint, the connection is configured using the
|
|
[cli Docker environment variables](https://godoc.org/github.com/moby/moby/client#NewEnvClient).
|
|
|
|
### Metrics:
|
|
|
|
- docker_log
|
|
- tags:
|
|
- container_id
|
|
- container_name
|
|
- stream
|
|
- fields:
|
|
- message
|
|
### Example Output:
