Default
read_write

server_id

In leader-follower topology, this value must be unique. In other words, the leader must have a different value than the follower and vice versa. If this is set to 0, then the server refuses any replication connections.

logging

format

timestamp

Format for timestamp in component logs. Valid values are ‘rfc3339’, ‘unix-epoch’. ‘rfc3339’ is the recommended format. It will result in all timestamps controlled by this job to be in RFC3339 format, which is human readable. This includes stdout, pre-start, and post-start logs. This does not include stderr logs from golang libraries. ‘unix-epoch’ will result in all timestamps being in the format they were before the rfc3339 flag was introduced. This format is different for different logs. We do not recommend using this flag unless you have scripts that expect a particular timestamp format.

Default
rfc3339

monit_startup_timeout

Default
true

remote_admin_access

When set to true, admin and roadmin will be able to connect from any remote host.

Default
false

roadmin_enabled

When set to true, a read-only admin user called roadmin is added
