In the listing that follows,  node_id  denotes either a storage node ID or the keyword  ALL , which indicates that the command should be applied to all of the cluster’s data nodes. Turns the cluster log on. Turns the cluster log off. Provides information about cluster log settings. Logs  category  events with priority less than or equal to  threshold  in the cluster log. Toggles cluster logging of events of the specified  severity_level . The following table describes the default setting (for all data nodes) of the cluster log category threshold. If an event has a priority with a value lower than or equal to the priority threshold, it is reported in the cluster log. Events are reported per data node, and that the threshold can be set to different values on different nodes. Note 4464 • CLUSTERLOG FILTER  severity_level • node_id  CLUSTERLOG  category = threshold • CLUSTERLOG INFO • CLUSTERLOG OFF • CLUSTERLOG ON •A description of the event. The most common types of events to appear in the log are connections and disconnections between different nodes in the cluster, and when checkpoints occur. In some cases, the description may contain status information. •The ID of the node reporting the event. •The severity of the event. •The type of node which is performing the logging. In the cluster log, this is always  [MgmSrvr] . •A timestamp in  YYYY - MM - DD HH : MM : SS  format. 23.5.3.1 NDB Cluster Logging Management Commands
