Get Started

Analyze Traces

Epsagon is as a powerful tool for analyzing traces and trends from your applications. Analyzing traces can be done from the traces search page:


Search first

Make sure you're familiar with searching and filtering before you continue.

Analyzing Requests and Errors

The two left-most analytics chart show how many requests are successful, and how many fail.

This analysis may help you answer questions such as:

  1. Is there a spike or steady-state in calls?
  2. Which errors show up the most? Are there new errors appearing?
  3. What is the ratio of errors compared to success?

Analyzing Latencies

The right-most analytics chart shows the average duration (latency) of the traces.

This analysis may help you answer questions such as:

  1. Is there a performance issue or degradation in call latency?
  2. How long does your application/user wait for a call?

Custom Analysis

You can visualize any metric by clicking Visualize, selecting a tag to aggregate, and selecting an aggregation function.

This analysis may help you answer questions such as:

  1. How many unique items were ordered over the past week?
  2. How many API errors occurred?
  3. What is the daily total order quantity?

If you don't see the tag you want to visualize, you can have it indexed.

To add the visualization to a custom dashboard, click Add to custom dashboard.

Trace Retention

You can retain traces (and trace-based metrics) for longer periods than the 7-day default:
