在 Grafana 上排序日志（来自 Loki）

Question

Scenario: The logs are in following format:

<SequenceID> <Level> <Message>

I have a requirement to sort the logs based on the SequenceID at Grafana.

Background: I am using promtail to ship logs where I create labels for SequenceID and Level. However, I am unable to find any valid visualization/transformation option (panel/widget) at Grafana Dashboard that would help me in creating a table where I can sort the log entries based on the sequenceID.

Also note: The logs are generated at microsecond level, hence can't rely on timestamp.

PS: When adding transformation "Labels to fields" for the label "SequenceID", I get below error: Pls note:

• There are multiple values in the dropdown below.
• There's only one value in the table where it doesn't make sense to sort.

Answer 1

Do the following steps:

• Select "Table" visualization

• Select "Label to fields" transformation

• Click in the "sequenceID" column name to change the order.

Answer 2

Solution: Selected "Table" visualization. The transformation steps are as below:

• Reduce

  Mode: Series to rows

  Calculations: "Step"

  Enable - Label to fields

Further, I used Filter data values and Filter by name transformation stages to filter the empty rows and remove a few columns.
