## Live Tailing
To view your logs live as they are added, choose `Live` from the refresh dropdown, and you should see your logs be displayed in real time.
Note that Live Tailing relies on two Websocket connections: one between the browser and the Grafana server, and another between the Grafana server and the Loki server. If you run any reverse proxies, please configure them accordingly.
> Note: This feature is only available in Grafana v6.3+
## Log Context
When using a search expression as detailed above, you now have the ability to retrieve the context surrounding your filtered results.
By clicking the `Show Context` link on the filtered rows, you'll be able to investigate the log messages that came before and after the
log message you're interested in.
> Note: This feature is only available in Grafana v6.3+
## Templating
Template variables are not yet supported by Loki.
