Before you can optimize your data, you need to understand what it contains, and separate the useful data from the noise. Mezmo’s Data Profiler feature enables you to get a detailed, granular view of the most common messages in your log data, and add processor components to handle specific message types.

​
Create a Data Profile

There are two ways to generate a data profile:
  1. As part of the Mezmo Flow onboarding process or the Log Volume Reduction pipeline creation process.
  2. Through the Data Profiler Processor, which you can set it up as a component within a Pipeline that you build yourself.

​
View the Data Profile

Once a Data Profile has been generated for the Source, you can access it through both the Processor itself, and the navigation in the Mezmo Web App.

The Data Profiler analyzes streaming telemetry data using multiple techniques so that you can have improved insights based on the type of telemetry data . Analysis of the telemetry is organized in three different tabs in the report: Message Templates, Field Summaries, and Log Metrics. Message Templates provide information on unstructured text messages, where Field Summaries provide better insights into structured data such as JSON logs.

​
Message Templates

The Message Templates section provides a report of log patterns discovered in the data. This enables you to understand how much specific log patterns contribute to the overall source volume, expressed as a percentage of the total data volume. With this information, you can determine if the logs matching the pattern are important for investigation and troubleshooting , or if they are low-value logs that can be archived and don’t need to be sent to your observability platform. The columns in the Message Templates section, which are all sortable, include:
  • Apps, which shows the number of apps that produced these log patterns. You can hover on the number to see the name of the app(s) that produced the log pattern.
  • Template shows the tokenized log lines with variables that change from message to message, such as IP or Host, and are replaced by<*>
  • Total Lines shows the number of log lines that match this pattern
  • Total Line Size shows the sum of all the log lines that match this pattern
You can see examples for each matching log sample by clicking the arrow next for each of the message templates.

Field Summaries

This is an experimental feature that is still in development. For access to this feature, reach out to your Customer Support Manager or support@mezmo.com.
Field summaries provide the analysis of telemetry data from the perspective of field values. The Field Summaries section provides a tabular view of all the Fields discovered from the events that are streaming through the pipeline during a profiler run. Click the arrow next to the field name to see the unique values associated with the field. You can also apply Processors to those unique values. Within the Field Summaries report, you will see: You can also apply Processors based on Field or Field Value. At the Field level, you can only select Remove Field. At the Field Value level, you can apply Processors such as Filter, Sample Processor, Dedupe Processor, and Throttle Processor. If you remove a field at the Field level, the Field Value processors are disabled because they are mutually exclusive. This table describes the value displayed based on the value type:

Log Metrics

The Log Metrics section provides a report of the profiled logs categorized by App, Host, Log Level and Log Type:
