在使用 promtail、loki 和 grafana 的设置中，grafana explore 中没有显示任何数据。这三个部分都在同一台机器上运行。
问题是：在哪里寻找设置中的错误？

promtail.yaml：
server:
http_listen_port: 9080
grpc_listen_port: 0
positions:
filename: /var/db/promtail/positions.yaml
clients:
- url: http://127.0.0.1:3100/loki/api/v1/push
scrape_configs:
- job_name: system
static_configs:
- targets:
- localhost
labels:
job: varlogs
__path__: /var/log/**/*log
这似乎没问题。测试：
promtail --config.file=promtail.yaml --log.level=info -print-config-stderr

loki 应用程序/服务已启动并运行。我还能在这里测试什么吗？

loki 的数据源创建方式：
- 类型：洛基
- URL：（
http://127.0.0.1:3100其他内容：保留默认设置）
查看 grafana/explore只显示没有数据，甚至没有任何过滤条件。按了Run query似乎没有任何效果。
Grafana 日志对我来说看起来不错：
