Log Filters

To filter out logs that you want to run your analytics query on, click image-20241107-194249.pngImage Added (Search logs). If no filters are specified, FuseQL will consider all log lines.

...

Aggregations

Once the log filters have been added, you can apply an aggregation operator on the log lines. By default, FuseQL will display the count of all log lines that match the filter conditions.

For more information on various supported aggregation operators, refer to Aggregation Operators.

Group Bys

FuseQL also supports grouping of log lines by label and facets. Click on the by dropdown to add group by fields to your aggregation operators. By default, FuseQL groups by everything, collapsing all the columns.

...

Limit To

By default, FuseQL limits the resulting time series values to the top 10. This can be changed by editing the dropdown.

...

Roll Up

FuseQL aggregates data by roll up time period (for example, five seconds). The roll up value is auto-selected by the user-selected time range, but can be edited if needed. Editing the roll up will change the number of bucketed results you see in the visualization.

Below is an example of using a 1m roll up in a time range of 5m resulting in 5 buckets.
