Troubleshooting Guide

A guide on debugging and troubleshooting Vector

This guide covers troubleshooting Vector. The sections are intended to be followed in order.

First, we're sorry to hear that you are having trouble with Vector. Reliability and operator friendliness are very important to us, and we urge you to open an issue to let us know what's going on. This helps us improve Vector.

1. Check Vector's logs

We've taken great care to ensure Vector's logs are high-quality and helpful. In most cases the logs will surface the issue:

Manual
Systemd
Initd
Homebrew

If you are not using a service manager, and you're redirecting Vector's output to a file then you can use a utility like tail to access your logs:

tail /var/log/vector.log

Tail logs:

sudo journalctl -fu vector

Tail logs:

tail -f /var/log/vector.log

Tail logs:

tail -f /usr/local/var/log/vector.log

2. Enable backtraces

You can skip to the next section if you do not see an exception in your vector logs.

If you see an exception in Vector's logs then we've clearly found the issue. Before you report a bug, please enable backtraces:

RUST_BACKTRACE=full vector --config=/etc/vector/vector.toml

Backtraces are critical for debugging errors. Once you have the backtrace please open a bug report issue.

3. Enable debug logging

If you do not see an error in your Vector logs, and the Vector logs appear to be frozen, then you'll want to drop your log level to debug:

Vector rate limits logs in the hot path. As a result, dropping to the debug level is safe for production environments.

Env Var
Flag
LOG=debug vector --config=/etc/vector/vector.toml
vector --verbose --config=/etc/vector/vector.toml
