Now that we have a loki data source we can query it with the LogQL query language.

In this video, we will try out many LogQL queries using the 'varlogs' selector that we just set up.

There are two types of LogQL queries:
1. Log queries returning the contents of log lines as streams.
2. Metric queries that convert logs into value matrixes.

A LogQL query consists of,
1. The log stream selector
2. Filter expression

We can use operations on both the log stream selectors and filter expressions to refine them.
