chronix.ingester

The Chronix Ingester batches up sample data from various sources and stores it as chunks in Chronix. Currently, only Prometheus is supported.

Building

Building requires Go 1.7 or newer, as well as a working GOPATH setup.

To build the ingester:

go build

Running

Example:

./chronix.ingester -url=http://my-solr-host:8983/solr/chronix -max-chunk-age=30m

To show all flags:

./chronix.ingester -h
Usage of chronix.ingester.exe:
  -checkpoint-file string
        The path to the checkpoint file. (default "checkpoint.db")
  -checkpoint-interval duration
        The interval between checkpoints. (default 5m0s)
  -chronix-commit-within duration
        The duration after which updates to Chronix should be committed. (default 5s)
  -create-statistics
        Whether to store some additional statistical data for each data chunk.
  -es.deleteIndexIfExists
        Deletes the index only with es.withIndex=true
  -es.sniffNodes
        Should elastic client sniff for ES nodes (only used with elastic search) (default true)
  -es.withIndex
        Creates an index (only used with elastic search (default true)
  -flush-on-shutdown

        The URL of the Chronix endpoint. (default "http://localhost:8983/solr/chronix")

Run in Docker container

A docker image is provided on Docker Hub. The Dockerfile defines the entrypoint to the chronix.ingester binary but no program arguments. You have to set the commands yourself, e.g.:

docker run --rm -it chronix/chronix.ingester -url=http://localhost:9200 -kind=elastic -es.deleteIndexIfExists=true

Testing

To run tests:

go test ./...

Configuring Prometheus

Sending samples to the Chronix ingester from Prometheus requires Prometheus version 1.2.0 or newer. To configure Prometheus to send samples to the ingester, add the following stanza to your Prometheus configuration file:

remote_write:
  url: http://<host>:<port>/ingest
