As soon as your test has started to collect data, the Timeline Report presents its graphs.

The Timeline report can be also viewed by clicking the 'Reports' button from the upper navigation bar, and then 'Show all Reports'.

Now, you’ll be able to see a list of all your Reports. Click on the one that you want to view. Then click on 'Timeline'.
On the left side of the screen, you'll notice the KPI selection panel.
The great advantage of this report is that it enables you to view many different types of KPIs within one graph, and by doing so easily visualize certain events that might have occurred throughout the test.

Here’s what each of these KPIs mean:

• USERS shows how many virtual users are currently active.
• HITS/S (Hits per second) is the number of HTTP/s requests per second that are generated by the test.
• RESPONSE TIME is the amount of time from the first byte sent to the server to last byte received at the client side.
• LATENCY is the time from sending the request, processing it on the server side, to the time the client received the first byte.
• BYTES/s is the average bandwidth consumption that’s generated by the test per second.
• CONNECT TIME is the measurement of how long it takes the user to connect to the server, and the server to respond, including SSL handshake.

KPIs By Labels

To view KPIs by labels, click on the arrow next to each KPI and choose the required label from the different options that open up. E.g. Errors of 'HTTP Request' in the example below.

You will now notice that the KPIs are available for every label in your test.

KPIs from APM Integrations 

KPIs from APM Integration profiles you have included in your test configuration will appear at the bottom of the list, after the built-in KPIs

Download Timeline Report KPI Data

It's possible to download the KPI data Blazemeter uses to build the Timeline Report, which can be done via a call to the following API:

https://a.blazemeter.com/api/v4/data/kpis?interval={{seconds}}&kpis[]={{kpi}}&ops[]={{operand}}&master_ids[]={{masterId}}&labels[]={{label}}

The above API call includes the following options:

• {{seconds}} = The number of seconds between each data point generated.
• {{kpi}} = The KPI you want to view. This parameter can be used multiple times in the same request to cover as many KPIs as you are interested in.  The list of values are as follows:
  na: Number of Active threads 
  ec: Error Count
  t: Response time
  n: Number of hits per second
  lt: Latency
  ts: Timestamp in epoch format
  by: Bytes per second
  ct: Connect Time
• {{operand}} = This is how you find the average, minimum, or maximum values for applicable KPIs. List of acceptable values are as follows:
  avg
  min
  max
• {{masterId}} = The master ID of the report you want to see the data from.
• {{label}} = The label ID of the label you're interested in.

Note: Use of the Blazemeter API requires authentication per the instructions found in the article Authorization.
