Callout Performance indicates "Unknown Status (Deprecated)"

[Eric Urban]

I have notice that despite the platform actively soliciting impressions, I am winning none. I pulled my performance report. Here is a sampling of the report for my US East bidder.

{
 "kind": "adexchangebuyer#performanceReport",
 "calloutStatusRate": [

  {

  {

  }
 ],

  {

  {

  {

  }
 ],
 "quotaThrottledLimit": 8716.598199,
 "latency95thPercentile": 34.87388724035608
}

As we can observe, the 95th percentile of latency is quite low at only 34 (presumably) milliseconds.

Looking at the 'calloutStatusRate'  in detailwe see that key 1 ("Callout successful") has a value of zero. This lines up with my observation that no impressions are being won.

 I am unsure about the units on the values, but I assume they are at least proportional to one another. That is to say, comparing their magnitudes is meaningful. The largest value is key 6 which is "Dropped because of selective callout." What does this mean? Also, what does key 18 mean ("All ads in response filtered.") ?

[Eric Urban]

Looking back through the performance reports, it appears key 6 is normally pretty high. This seems reasonable as the platform can't solicit all ads to all bidders. Looking at my performance report it appears the value associated with key 1 just tapered off to zero over time. Specifically at Fri Jul 25 05:25:00 UTC 2014 it reached zero and has stayed there. At Thu Jul 24 00:00:00 UTC 2014 the value of key 1 was 1.232. At that time I was able to win impressions, although I have no idea what value 1.232 means. 

What can be done to troubleshoot this? I am still actively receiving callouts, but not winning any impressions. Raising the bid response CPM does not change the situation.

Hello Eric,

When you are dropped because of selective callout, that is because you were throttled. How long has this been going on? Your bids may initially be throttled because the likelihood of being throttled decreases as you bid more. For example, if you stopped bidding for a length of time, you may be throttled to such an extent that all of your bids are filtered. On the other hand, if you are actively bidding over a period of 24 hours, you should notice a decrease in your throttling.

The value associated with each status is the QPS; in other words, you had an average of 1.232 successful callouts per second at that time.

Hi Mark,

As I stated in my second post "Specifically at Fri Jul 25 05:25:00 UTC 2014 it reached zero and has stayed there".  "It" being the value associated with key 1 of the callout status for the key with numerical value. I have been bidding continuously on callouts in that time period.

What defines a callout as being successful?

Hello Eric,

Assuming that the bids you're sending in are valid and aren't timing out, they would be considered successful. Do you have real-time feedback enabled? If so, what is the creative status you are receiving? It'd be unusual for successful callouts to be stuck at 0 for days on end when you're actively bidding without any errors. I'll take a closer look at your account and see if I can figure out the cause.

Hello Eric,

Actually, I'll need more information such as your AccountId to look up your details. We should move this conversation over to our support alias (adxbuyera...@google.com).

Hi Mark,

An email has been sent. Thank you for looking into this.
