 Loki provides the excellent [LogCLI](https://grafana.com/docs/loki/latest/tools/logcli/) tool to query without Grafana.
 You can query logs from your cluster like this:
 ```bash
-logcli query --bearer-token=/token  --addr=https://yourcluster.dev.restate.cloud:3100 '{kubernetes_container_name="restate"}'
+logcli query --bearer-token=/token --addr=https://yourcluster.dev.restate.cloud:3100 '{kubernetes_container_name="restate"}'

 Use `-f` to tail logs - check the [LogCLI docs](https://grafana.com/docs/loki/latest/tools/logcli/#logcli-query-command-reference)
 for more tips.
