# Logstash | ||
|
||
[Logstash](https://www.elastic.co/products/logstash) is an open source, server-side data processing pipeline that ingests data from a multitude of sources simultaneously, transforms it, and then sends it to your favorite “stash.” | ||
|
||
## TL;DR; | ||
|
||
```console | ||
$ helm install stable/logstash | ||
``` | ||
|
||
## Installing the Chart | ||
|
||
To install the chart with the release name `my-release`: | ||
|
||
```console | ||
$ helm install --name my-release stable/logstash | ||
``` | ||
|
||
## Uninstalling the Chart | ||
|
||
To uninstall/delete the `my-release` deployment: | ||
|
||
```console | ||
$ helm delete my-release | ||
``` | ||
|
||
The command removes nearly all the Kubernetes components associated with the | ||
chart and deletes the release. | ||
|
||
## Best Practices | ||
|
||
### Release and tune this chart once per Logstash pipeline | ||
|
||
To achieve multiple pipelines with this chart, current best practice is to | ||
maintain one pipeline per chart release. In this way configuration is | ||
simplified and pipelines are more isolated from one another. | ||
|
||
### Default Pipeline: Beats Input -> Elasticsearch Output | ||
|
||
Current best practice for ELK logging is to ship logs from hosts using Filebeat | ||
to logstash where persistent queues are enabled. Filebeat supports structured | ||
(e.g. JSON) and unstructured (e.g. log lines) log shipment. | ||
|
||
### Load Beats-generated index template into Elasticsearch | ||
|
||
To best utilize the combination of Beats, Logstash and Elasticsearch, | ||
load Beats-generated index templates into Elasticsearch as described [here]( | ||
https://www.elastic.co/guide/en/beats/filebeat/current/filebeat-template.html). | ||
|
||
On a remote-to-Kubernetes Linux instance you might run the following command to | ||
load that instance's Beats-generated index template into Elasticsearch | ||
(Elasticsearch hostname will vary). | ||
|
||
``` | ||
filebeat setup --template -E output.logstash.enabled=false \ | ||
-E 'output.elasticsearch.hosts=["elasticsearch.cluster.local:9200"]' | ||
``` | ||
|
||
