An error log records events or diagnostic messages produced by software or infrastructure. It can help locate the stage at which an operation failed, but messages need context and interpretation. Logs can also contain private addresses, tokens or account details, so useful evidence should be reviewed and redacted before it is shared beyond the appropriate support process.
A practical example
A player log may show that a playlist request completed but a later media request failed. That sequence helps separate catalogue loading from playback access, while the exact endpoint and account-related parameters may need to be hidden in a public example.
A common misunderstanding
A log entry is evidence of a reported event, not automatic proof of the underlying cause. Avoid sharing a complete unreviewed log when a short redacted extract answers the support question.
