Collection browser contains break down of new, total and unique browsers provided in the metrics by time periods.
This value is provided for Web Type apps through Countly Web SDK
For shorter representation, these stats are abbreviated as:
- n - new
- t - total
- u - unique
There are 4 types of documents available:
- Zero document, which id is formed from {appID}_{year}:0 And it contains stats breakdown by months and weeks for the specified year
- Month document, which id is formed from {appID}_{year}:{month} And it contains stats breakdown by days of the month
- Splitted zero document which id is formed from {appID}{year}:0{shardname}
- Splitted month document which id is formed from {appID}{year}:{month}{shardname}
Here is the list of possible fields
| Field | Description | Example |
|---|---|---|
| _id | ID formed as {appID}{year}:0 or {appID}{year}:{month} or {appID}{year}:0{shardname} or {appID}{year}:{month}{shardname} | 542e95d747f0be510c000004_2014:10 |
| a | App ID | 542e95d747f0be510c000004 |
| d | Data for specific document | { "2": { "Chrome": { "u": 95 }, "Internet Explorer": { "u": 100 }, "Firefox": { "u": 108 }, "Safari": { "u": 112 }, "Opera": { "u": 97 } }, "3": { "Chrome": { "u": 112 }, "Internet Explorer": { "u": 103 }, "Firefox": { "u": 98 }, "Opera": { "u": 87 }, "Safari": { "u": 88 } } } |
| m | {year}:{month} for which data is provided | 2014:10 |
