View and Download MongoDB Logs¶
On this page
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.
You must have Project Data Access Admin privileges or greater
to download logs.
M0 free clusters and M2/M5 shared clusters do not provide downloadable logs.
