 If you want to install Loki, Grafana, Prometheus and Promtail all together you can use the `loki-stack` chart, for now we'll focus on Promtail. Let's create a new helm value file, we'll fetch the [default][default value file] one and work from there:

 First we're going to tell Promtail to send logs to our Loki instance, the example below shows how to send logs to [GrafanaCloud][GrafanaCloud], replace your credentials. The default value will send to your own Loki and Grafana instance if you're using the `loki-chart` repository.

+## Run promtail with syslog support
+
+In order to receive and process syslog message into promtail, the following changes will be necessary:
+
+* Review the [promtail syslog-receiver configuration documentation](/docs/clients/promtail/scraping.md#syslog-receiver)
+
+* Configure the promtail helm chart with the syslog configuration added to the `extraScrapeConfigs` section and associated service definition to listen for syslog messages. For example:
+
+```yaml
+extraScrapeConfigs:
+  - job_name: syslog
+    syslog:
+      listen_address: 0.0.0.0:1514
+      labels:

+  relabel_configs:
+    - source_labels: ['__syslog_message_hostname']

+## Run promtail with systemd-journal support

+In order to receive and process syslog message into promtail, the following changes will be necessary:

+* Configure the promtail helm chart with the systemd-journal configuration added to the `extraScrapeConfigs` section and volume mounts for the promtail pods to access the log files. For example:

+```yaml
