Extract Month Name From Timestamp

Get the name of the month from a timestamp using the time:monthName() function

Query
logscale
time:monthName(timestamp, as=month)
Introduction

In this example, the time:monthName() function is used to extract the month name from a specific timestamp 2025-08-27 08:51:51.312, demonstrating how to get the month name from a datetime.

Step-by-Step

  1. Starting with the source repository events.

  2. logscale
    time:monthName(timestamp, as=month)

    Extracts the month name from the @timestamp field and returns the result in a new field named month. If the as parameter is not specified, the result is returned in a field named _monthName as default.

  3. Event Result set.

Summary and Results

The query is used to extract the month name from a timestamp, which is useful for creating human-readable output and reports.

This query is useful, for example, to generate readable reports, create user-friendly displays, or label data with month names.

Sample output from the incoming example data:

@timestampmonth
2025-08-27 08:51:51.312August

The result shows how the time:monthName() function extracts the month name (in this case August) from the timestamp, returning it as a string value.

For visualizing this data, consider using a Bar Chart widget to show event counts by month name, or a Table widget to display events with their corresponding month names. The time:monthName() function is often used with other time functions like time:year() and time:dayOfMonth() for complete date analysis.
