Ad Inspector
(Formerly known as "Ad Debug")
We provide near real-time data on the ads requested for your content. Analyze this information to gain insights into ad insertions, such as:
- Verifying ad requests and responses.
- Checking for errors and discovering their root cause.
- Performing end-to-end auditing of a single playback session.
Ad Jobs
Ad insertion data is collated and presented as an ad job. The scope of an ad job varies by content type.
-
Live Stream: The system generates an ad job whenever playback encounters an upcoming ad break.
-
VOD: The system generates a single ad job upon initiating playback. This ad job contains data for all of the asset's ad breaks.

-
An ad job describes:
- The set of ads that were requested.
- The ad decision server's response for each of those ads.
- The tracking data provided to the ad decision server.
As illustrated above, each ad job consists of the following components:
-
Ads: Each ad listed under the job corresponds to a single ad during an ad break. Data shows whether the ad was selected for use during the ad break, the position in the ad break the ad was inserted into, and the status of the ad asset.
-
Transactions: A transaction describes an ad request and the response provided by an ad decision server.
- Request: An ad request is generated for the initial request to the ad decision server and for each wrapper spawned from it. The following information is captured for each ad request: raw URL, macros, HTTP headers, and processing information.
- Response: For each ad request, we provide the raw XML from the ad decision server and a summary of the response, including errors. If the ad request resulted in VMAP and VAST wrappers and a creative, that information is also included in the raw XML response.
- An error during an ad request may prevent an ad response from being provided.
-
Beacons: A beacon consists of the tracking data reported by our system to the ad decision server.
Data Retention
The retention policy for ad insertion data is 7 days.

Troubleshoot Ad Jobs
Troubleshoot ad jobs that contain completed transactions with warnings, failed transactions, or both.
You can audit your own playback session to correlate the playback experience to ad insertion data.
An ad job is considered successfully completed when the initial transactions to the ad decision server are completed in a timely manner. However, a successful ad job may contain transactions with warnings or failures.
Troubleshoot an Ad Job
- Select the desired ad job.
- Select the desired transaction.
- From the Request tab, review the URL, query string parameters, and headers for the request submitted to the ad decision server.
- From the right-hand pane, review the Failure Reason field.
- Select the Response tab.
- From the right-hand pane, review the following fields:
- Failure Reason: Indicates the reason that a transaction failed.
- Errors: Indicates any errors that occurred when processing the response.
- Warnings: Indicates any warnings that occurred.
- Use the information uncovered in the previous step to perform additional investigation into the failure, error, or warning.
View the transaction in JSON format by selecting Export Transaction JSON. The raw_response JSON field contains the raw data for the response in XML format.
Warnings
A warning indicates that the request to the ad decision server was incomplete or improperly formed. For example, a warning is generated when the request contains missing parameters or values.
A warning triangle icon appears next to both of the following:
- Ad jobs that contain at least one transaction with a warning.
- The transaction to which the warning applies.
View the warning by hovering over it as illustrated below.
In the above illustration, the ad job contains a warning indicating that a transaction contains 4 empty impressions. Inspecting the transaction's raw response reveals that it does contain 4 empty impressions. Reviewing the <Error> tag indicates that an error also occurred. Although the ad decision server returned 4 empty impressions and an error, an ad was still served to the viewer.
<Impression id=\"3rdparty\"/>
<Impression id=\"3rdparty\"/>
<Impression id=\"3rdparty\"/>
<Impression id=\"3rdparty\"/>Failure
A failed transaction indicates that an ad impression was not delivered either because the transaction did not complete on time or it resulted in an empty or malformed response. View the failure reason by hovering over the transaction's status.
Ad Request Failure Reasons
Failures can occur at various stages of processing an ad request. Uplynk categorizes failure reasons into failure types based on these stages.
The failure types are:
In certain cases, the "Error" section of the job or transaction details includes additional information about an ad failure that can be sent to Uplynk Support to help troubleshoot an inquiry about a failed job or transaction.
Request
An error occurred while establishing an HTTP connection to the ad server and downloading the ad response. To troubleshoot request failures, contact the ad server. The ad server may have some data, or it may not have any data. The Ad Analytics reports can be used to gather data on how frequently these errors occur.
Request Errors
| Failure | Description |
|---|---|
| connection error | An error occurred establishing the connection with the ad server. This typically means the ad server was unreachable. |
| connection timeout | The ad server did not respond quickly enough to the connection attempt. Standard timeout is limited to 1 second. |
| download error | There was an error attempting to download the prepared ad response from the ad server. |
| download timeout | The ad server took too long to send the next packet while downloading the ad response. Standard timeout is limited to 1 second. |
| invalid URL | The URL used to make the request was not valid. This typically happens because a wrapper URL contains a bad URL. |
| non 200 | The ad server responded with an error code. Usually either a 4xx or 5xx HTTP status code. |
| read timeout | The ad server took too long to respond back while preparing the ad response. Standard timeout is limited to 1 second. |
| SSL error | There was a problem with the ad server's security certificate. |
Response
A high-level check of the response contents ensuring they are in a valid format. For these failures, the ad server should be notified.
Response Errors
| Failure | Description |
|---|---|
| empty response | The ad response is an empty string with no content. |
| invalid XML | The XML of the ad response was malformed. |
| response too big | The ad response was too big. Ad responses are limited to 1 MB to ensure processing ad jobs are not blocked by an enormous ad response. |
Parsing
Reading and parsing the response to extract the ad information.
For the no ad break, no ads returned, and no media file errors, the ad server did not provide the needed information. Contact the ad server to determine why the responses did not include that data. Parse errors can occur for a variety of reasons. Contact support with any questions and include any additional information provided in the "Errors" section.
Parsing Errors
| Failure | Description |
|---|---|
| no ad break | The VMAP ad response did not contain any ad breaks. |
| no ads returned | The ad response did not contain any ads. |
| no media file | The ad response contained ads, but none of the ads contained media files. |
| parse error | Something in the ad response caused parsing to fail. |
Processing
After parsing, additional actions are taken to ensure the ads are prepared for stitching. This also covers any issues before or between the other stages.
Processing Errors
| Failure | Description |
|---|---|
| process timeout | The allotted time for completing the ad job expired before being able to finish processing the ad request. |
