View and Download MongoDB Logs

Each mongod, mongos, and mongosqld tier keeps an account of its activity in its own log file. Atlas retains the last 30 days of log messages and system event audit messages for each tier in a cluster. The Performance Advisor retains at most 7 days of logs for each process in a cluster.

Important

You must have Project Data Access Admin privileges or greater to download logs.

Note

M0 Free Tier and M2/M5 shared clusters do not provide downloadable logs.
