The MidoNet Cluster writes log messages to the
/var/log/midonet-cluster/midonet-cluster.log file.
During troubleshooting periods, you can increase the logging level via the
mn-conf utility.
The available log levels are: DEBUG, INFO, WARN, ERROR
![[Important]](../common/images/admon/important.png) | Important |
|---|---|
In production environments it is not recommended to enable DEBUG logging due to impact on performance, unless it’s really required. |
To check the currently configured level for a certain Cluster host, execute the following command on that host:
$ mn-conf get cluster.loggers.root
cluster.loggers.root = INFOTo increase the log level for this host to DEBUG, execute the following
command:
$ echo "cluster.loggers.root : DEBUG" | mn-conf setThis change applies immediately and does not require a Cluster restart.
It is also possible to increase the log level globally (i.e. for all Cluster hosts) by changing the default template’s value:
$ echo "cluster.loggers.root : DEBUG" | mn-conf set -t default
Note that if a host has a local log level configured, this will have higher priority than the template configuration.
To see the current template configuration, execute the following command:
$ mn-conf get cluster.loggers.root -t default
cluster.loggers.root = INFO
