Log Forwarder Configuration Files

Note

This page describes a legacy configuration file format. You should only use this information if you're using the deprecated realm-cli.

Any configuration files you pull with App Services CLI or export from the UI use the latest configuration version. For detailed information on the current configuration file format, see App Configuration.

You define log forwarder configuration files in the /log_forwarders directory.

app/
└── log_forwarders/
    └── <Name>.json
log_forwarders/<name>.json
{
  "name": "<name>",
  "log_types": [ "<type>", ... ],
  "log_statuses": [ "<status>", ... ],
  "policy": { batching policy },
  "action": { action configuration }
}

  • graphql

  • push

  • schema

  • service

  • sync

An array of one or more log statuses that the forwarder should send to a service. App Services only forwards a log if its type is listed and its type is listed in log_types.

The array may contain the following log statuses:

  • error

  • success

policy

An object that configures the forwarder's batching policy.

To forward logs individually:

{ "type": "single" }

To group logs into batches:

}

To forward logs with a custom function:
