Debugging Uptrace issues
Uptrace version
Before trying anything else, make sure you have the latest Uptrace version.
To see the installed Uptrace version:
uptrace version
Then check the latest available version at GitHub Releases.
Logging
You can view Uptrace logs using journalctl command:
sudo journalctl -u uptrace -f
By default, Uptrace only logs failed HTTP requests and failed ClickHouse queries. You can configure Uptrace to log all requests and queries by changing the config at /etc/uptrace/uptrace.yml:
# Enable to log HTTP requests and ClickHouse queries.
debug: true
Or change DEBUG environment variable in /etc/uptrace/uptrace.conf:
# Configures Uptrace logging level.
# - 0 - disable logging
# - 1 - log failed requests and queries
# - 2 - log all requests and queries
DEBUG=2
And then restart Uptrace:
sudo systemctl restart uptrace
To check the status of the service:
sudo systemctl status uptrace
Resetting ClickHouse database
If ClickHouse queries are failing, you can try to to reset ClickHouse database:
uptrace ch reset
The check the database status:
uptrace ch status
Resetting PostgreSQL database
Just like with ClickHouse, you can reset the PostgreSQL database that Uptrace uses to store metadata:
uptrace db reset
The check the database status:
uptrace db status
