* If `SENTRY_DSN` environment variable is set, panics are reported to Sentry.
116
116
* If `SENTRY_DSN` and `SENTRY_LOGS=1` environment variables are set, logs are uploaded to Sentry.
117
117
* If `SENTRY_DSN` and `SENTRY_TRACING=1` environment variables are set, traces are uploaded to Sentry.
118
+
* Optional syslog integration allows transmitting application logs to a syslog daemon. When present, the `SYSLOG_ADDR` environment variable enables the integration, and the variable's value is used to configure the absolute path to a Unix socket (usually located at `/dev/log` on Unix systems) or a network address of one of the following formats:
119
+
* for TLS over TCP: `tcp+tls://host:port`;
120
+
* for plain TCP: `tcp://host:post`;
121
+
* for UDP: `udp://host:port`.
