Monitoring API Analytics

Use analytics to monitor your API's performance.

Analytics information is available:

  • For APIs via APIs > My APIs > choose API > Analytics.
  • For apps via Apps > My Apps > choose app > Analytics.

The information on the Analytics pages is very similar for both apps and APIs, but there are some differences. For example, certain information is only available in the API charts.

What API analytics information is available?

The platform includes a number of charts and logs to help you monitor your API's performance from different views. Chart data can be used to monitor API usage over time or to troubleshoot errors with API operation. Usage logs that include request and response message data for API, App, and Contract activity can be queried and viewed.

Note: To gather detailed analytics info, you'll need to make sure the Detailed Auditing policy is attached to the API. See Why is some of my analytics information missing?

Go to: APIs > My APIs > choose API > Analytics.

The options available are summarized in the table below.

API Analytics Dashboard

The API Analytics Overview section includes a barometer-style Dashboard that gives you an overview of your API's throughput, latency, and success rate.

You can narrow down the data by the following:

  • Implementation: Sandbox or Live
  • Interval: 1 Sec or 1 Min

An example is shown below.

API Analytics Dashboard

The Dashboard includes a summarized data representation of the following:

  • Throughput (tps): Summarizes maximum throughput per second over the last 24 hours, and the total number of requests.
  • Average Latency: Provides low and high message latency values, in milliseconds.
  • Fault (fps): Summarizes the number of fault messages per second in the specified period.

What information can I see on the API Charts page?

You can use performance charts to monitor API usage over time or to troubleshoot errors.

The Charts page allows you to set criteria and view activity on three charts. You can also query usage and performance data in the Logs section on the same page. For more information about the logs, which you can also see on a separate page, see What information can I see on the API Logs page?

Go to: APIs > My APIs > choose API > Analytics > Charts.

In this section:

API Charts: Data set

You define the data set represented in the chart by using the filters as needed to specify implementation, app, duration, and time range, as covered in API Charts: Filters below.

However, charts are populated from usage "roll-up" data that is gathered during message processing. The platform matches the roll-up data sets that most closely match the values specified. For example, if the current time is 17:35 and you choose a duration of 1 day and an interval of 15 mins, the chart shows data from 18:00 the previous day to 18:00 on the current day.

API Charts: Types

A sample chart is shown below.

API Analytics: Charts

There are three charts. Hover over any data point in any of the charts to view detail including Date, Time, Average Response, max Response, Min Response, Success Count, Throughput, and Fault Count. All chart data is in milliseconds (ms).

Chart Description Example
Latency

Summarizes latency as a line over the time period.

Drag and drop using the mouse to zoom or move on the chart.

Success Chart: Detail

API Charts: Filters

On the Analytics > Charts page, you can filter by:

  • Implementation (Live or Sandbox)
  • All apps or a specific app that is contracted with the API.
  • Duration. Controls the time period to be shown on the chart. You can choose to show the last: 5 Minutes, 15 Minutes, 1 Hour, 1 Day, 1 Week, 1 Year.
  • Interval: The time interval determining the data points on the chart. Options adjust based on the value for Duration. For example, if Duration is 5 minutes, Interval is 5 sec. If Duration is 1 year, Interval is 1 week.

Chart data is presented based on the selected Duration and Interval, which together represents the total time range displayed.

API Charts: Using Zoom

When you've defined the data set you want to view, using the filters, there are a couple of other ways you can narrow down the information you need:

Zoom feature

The zoom feature is below the filters. An example is shown below.

Charts: Zoom feature

Here, you can narrow down the data set that's shown in the chart.

Time increments on the Zoom feature work together with the Duration setting. For example, if Duration is 1 Hour, the Zoom increments are All, 5m, 15m, and 30m, as shown above. If Duration is 1 Day, zoom increments are All, 1h, 3h, 6h, 12h.

Zooming with the mouse

You can zoom with the mouse on a specific area of data in the chart, to examine it more closely.

Place the mouse on one side of the area, then drag to the other side and let go of the mouse, as shown below. The area you defined is enlarged on the chart.

Steps 1 and 2: Click on one side, then drag to the other side. 1) Charts: Zoom feature  Charts: Zoom feature
Step 3: Release to enlarge Charts: Zoom feature

Refresh

After zooming in, click the Refresh icon at the top left to:

  • Reset the zoom settings on the chart. Filter settings are preserved.
  • Refresh the chart data, based on the selected Duration and Interval, which together represent the total time range displayed.

What information can I see on the API Licenses page?

If your API is using the Licenses feature, you might want to monitor the API's performance for each license.

Go to: APIs > My APIs > choose API > Analytics > Licenses.

The platform includes a set of monitoring tools, including pie charts and bar charts, to help you monitor by license.

Three choices are available:

  • API Usage by License
  • API Usage by App
  • API Quota Usage

From the API Details page, click Analytics on the left menu, and then click Licenses.

There are certain prerequisites that must be in place for monitoring information to be displayed correctly. Make sure:

  • Your API is using the Licenses feature.
  • Your licenses include a quota policy.
  • Your time zone is set correctly in the configuration settings for the underlying infrastructure (configuration settings, com.soa.rollup.configuration, monitoring.rollup.configuration.dailyRollupTimeZones setting). The time zone setting affects the way the data is rolled up into increments such as hour and day. If the settings are not correct, ask your Site Admin to adjust the time zone.

The options available are summarized in the table below.

This option... Shows this information...
API Usage by License

Pie charts that breaks down the total traffic to the API by license. This shows which license is using which portion of the API, out of the total traffic. Pie charts show the breakdown for the following metrics:

  • Usage count (total number of messages)
  • Request message size
  • Response message size

By default, three charts are generated for each license.

API Usage by App

Bar charts that break down the total traffic to the API by app. This shows metrics for the app's usage of the API, including:

  • Usage count (total number of messages)
  • Average response time (in milliseconds)
  • Response message size

By default, three charts are generated for each app.

API Quota Usage Only valid if a quota policy is attached to a license the API is using. This chart shows app consumption of the API as a bar chart, with each time slot being a bar, and additionally displays the quota threshold as a line across the chart. If the app exceeds the consumption defined by the quota, the bar is shown in red; if the app consumption is within quota, the bar is blue.

Analytics by License: Graph Controls

When you choose Analytics > Licenses, you can adjust the chart settings so that you see the exact information you need. Settings and their values are shown below.

Setting Values/Description
Implementation Sandbox or Live
Report period

A drop-down menu that allows you to select the time period to be shown in the chart. When you select a new duration, the Performance Chart data is automatically refreshed. Choices:

Who can see my API's performance metrics?

To see an API's performance metrics, a user must have one of the following permissions:

  • API Admin—Either the user who created the API, or a user who has been invited to join the API Admin team and has accepted the invitation.
  • Business Admin
  • Monitor—A user who is not an API Admin, but has been assigned Monitor permission, can monitor the API metrics but cannot perform other activities that the API Admin can do, such as modify the API.

Back to top

How do I monitor my API's performance for a specific app/API contract?

You can view monitoring charts and logs for any specific contract your API has with an app, as long as monitoring is turned on for your API.

Note: If the specified time period includes a point where the contract was revised, or suspended and resumed, or the contract was cancelled and a new one created, the chart or graph shows all transaction info between the app and the API in the selected time period. However, only in the case where the contract was revised, there is uninterrupted service. In other scenarios, service is suspended or stopped and is then resumed or restarted, with a period in between where the contract is not active.

To monitor API performance for a specific contract

  1. Log in and go to the API Details page for your API.
  2. On the left menu, click Analytics.
  3. Choose one of the following options, to view contract information in different ways:
    • Overview: Choose the environment. Here, in the Usage by App pie chart, you can see what portion of your API's total traffic is generated by a specific app.
    • Charts: Choose the environment and the app, and other values as needed. Here, you can view transaction volume, success/fault, and how the traffic measures against min/max average transaction time, if specified. You can also export the chart information.
    • Logs: Choose the environment and the app, and date range if needed. Here, you can view specific transaction logs. You can also export the log information.
    • Licenses: Choose the environment and the app, and other values as needed. Choose API Usage by App.

Why is some of my analytics information missing?

The storing of analytic information for app/API usage is controlled by the policies that are attached to the API. For example:

  • If you don't attach the AtmosphereApplicationSecurityPolicy policy to the API, calls to the API endpoint are logged, but there are no records of the app/API interactions, such as the  APIs > My APIs > choose API > Analytics > Overview > Usage by App chart or, for app developers, the Apps > My Apps > choose app > Analytics > Overview > Usage by API chart.
  • If you don't attached the Detailed Auditing policy to the API, calls to the API endpoint show up in the Overview and Charts section but do not appear in the logs.
