Realm is now Atlas Device SDK – Learn More

Overview

Function logs are created whenever a user calls an Atlas Function using a Realm SDK. While you can execute Functions with a Trigger, only functions directly called from an SDK generate logs of the function type.

Log Format

Function log entries have the following form:

Logs:
[
   <log line>,
   <log line>,
   ...
]
{
   "arguments": [
      <arg1>,
      <arg2>
   ],
   "name": <function name>,
   "service": ""
}
Function Call Location: <location>
Compute Used: <number> bytes•ms
Remote IP Address: <ip address>
SDK: <sdk>
Platform Version: <version>
