Percona Server for MongoDB parameter tuning guide

Percona Server for MongoDB includes several parameters that can be changed in one of the following ways:

Use the setParameter admonitions in the configuration file for persistent changes in production:

  <parameter>: <value>

Use the --setParameter command line option arguments when running the mongod process for development or testing purposes:

$ mongod \
 --setParameter <parameter>=<value>

Use the setParameter command on the admin database to make changes at runtime:

> db = db.getSiblingDB('admin')
> db.runCommand( { setParameter: 1, <parameter>: <value> } )


See what parameters you can define in the parameters list.
