How Long Should You Retain Application Logs?
A practical retention guide for application, infrastructure, audit, and security logs—balancing investigations, compliance, and cost.
The short answer
Most application troubleshooting needs days to a few weeks of hot logs. Security, audit, and customer investigations often need months. The mistake is applying one premium retention setting to every stream. Keep high-value logs as long as the workflow requires, and store high-volume history on a platform where longer retention is economically realistic.
Match retention to the question you will ask
On-call: 7–14 days of application and platform logs is usually enough to reconstruct an incident. Product analytics-from-logs and abuse investigations often need 30–90 days. Regulated audit trails may need a year or more—confirm with counsel, not a vendor blog.
Do not retain everything at the hottest tier
Debug logs from a staging cluster do not need the same window as production payment errors. Split services, environments, and event classes. LogHouse services exist so teams can set retention per workload instead of one global delete date.
Searchable beats “in an archive somewhere”
Cold object storage is cheap until an incident requires rehydration at 2 a.m. If you know you will search the data, keep it on analytical storage. If you will almost never read it, a true archive with a documented restore path is fine.
