LoggingSlack
Welcome to LoggingSlack – a logging backend for SwiftLog that sends critical log messages to Slack.
Usage
Setup Incoming Webhooks
LoggingSlack uses Incoming Webhooks to send log messages to a Slack channel.
Once you've setup Incoming Webhooks, you should have a webhook URL that you can use to configure LoggingSlack.
Bootstrap SwiftLog
LoggingSlack is intended to be used as a secondary logging backend to send critical log messages directly to Slack.
You can use SwiftLog's MultiplexLogHandler
to setup LoggingSlack with another logging backend.
import Logging import LoggingSlack let webhookURL = URL(string: "https://hooks.slack.com/services/T1MGQL1L8/RM2LE5QLF/YH036NhldqitdR1lVd5NLS6z")! LoggingSystem.bootstrap { label in MultiplexLogHandler([ // Setup SlackLogHandler with a webhook URL SlackLogHandler(label: label, webhookURL: webhookURL), // Setup the standard logging backend to enable console logging StreamLogHandler.standardOutput(label: label) ]) }
Using a Logger
You can now use SwiftLog as usual and critical log messages are sent directly to Slack.
import Logging let logger = Logger(label: "com.example.ExampleApp.main") logger.critical("Something went wrong!")
Logger Output
The logger will output a Slack message and a console message since both logging backends were setup.
2020-02-15T19:30:00-0800 critical: Something went wrong!
Log Level Threshold
Only critical
log level messages are sent to Slack by default.
You can adjust the log level threshold by changing the globalLogLevelThreshold
static property on SlackLogHandler
.
For example, this will configure LoggingSlack to send all error
log level and above messages to Slack.
SlackLogHandler.globalLogLevelThreshold = .error
