| CassandraKeyspace | string | Cassandra keyspace. |
| CassandraTable | string | Cassandra table. |
| ClusterName | string | Cluster name. |
| CodeCacheAfter | long | Code cache after garbage collection (in bytes). Code cache stores native code generated by JVM. |
| CodeCacheBefore | long | Code cache before garbage collection (in bytes). Code cache stores native code generated by JVM. |
| Collections | int | The number of garbage collections. |
| CompressedClassSpaceAfter | long | Compressed class space after garbage collection (in bytes). Compressed class space stores class information referred to by the objects in the JavaHeap. |
| CompressedClassSpaceBefore | long | Compressed class space before garbage collection (in bytes). Compressed class space stores class information referred to by the objects in the JavaHeap. |
| DeletionInfo | string | Deletion info. |

| EdenSpaceAfter | long | Eden space after garbage collection (in bytes). Eden space is the memory region where objects are allocated when they are created. |
| EdenSpaceBefore | long | Eden space before garbage collection (in bytes). Eden space is the memory region where objects are allocated when they are created. |
| Endpoint | string | IP address of an endpoint. |
| EventCategory | string | Category of the logging event, e.g. startup, garbage_collection, compaction. |

| EventType | string | type of the logging event, e.g. commit_log_replay_skipped, unknown_table. |
| Exception | string | Throwable trace bound to the logging event, by default this will output the full trace as one would normally find with a call to Throwable.printStackTrace(). |
| GCType | string | The type of garbage collection, e.g. ParNew, MarkSweepCompact, G1 Old. |
| HostId | string | The GUID assigned in the Cassandra cluster to uniquely identify this node. See the system.local table or nodetool status to find information about the host by its HostId. |

| MaxMemory | long | The maximum amount of memory (in bytes) that can be used for memory management. |
| Message | string | Application supplied message associated with the logging event. |
| MetaspaceAfter | long | Metaspace after garbage collection (in bytes). Metaspace stores classes metadata. |
| MetaspaceBefore | long | Metaspace before garbage collection (in bytes). Metaspace stores classes metadata. |
| OldGenAfter | long | Old Generation after garbage collection (in bytes). Old Generation is used to store long surviving objects. |
| OldGenBefore | long | Old Generation before garbage collection (in bytes). Old Generation is used to store long surviving objects. |
| PartitionKey | string | Partition key. |
| PartitionSize | int | Partition size. |
| PendingTasks | int | The number of pending tasks in gossip stage. |
| PercentFull | real | The percentage of full heap. |
| PermGenAfter | long | Permanent Generation space after garbage collection (in bytes). Permanent generation stores classes metadata (renamed to Metaspace in Java 8). |
| PermGenBefore | long | Permanent Generation space before garbage collection (in bytes). Permanent generation stores classes metadata (renamed to Metaspace in Java 8). |
| RequestedColumns | int | The number of columns requested. |
| _ResourceId | string | A unique identifier for the resource that the record is associated with |
| SessionId | string | Unique string identifying what query was running when this log was emitted. Use SHOW SESSION <SessionId> to find details of the query's activity. |
| SliceEnd | string | The end of the the column slice inclusive. |
| SliceStart | string | The start of the column slice inclusive. |
| SourceFile | string | File name where the logging request was issued. |
| SourceLine | int | Line number where the logging request was issued. |
| SourceSystem | string | |
| SSTableName | string | SSTable name. |
| _SubscriptionId | string | A unique identifier for the subscription that the record is associated with |
| SurvivorSpaceAfter | long | Survivor space after garbage collection (in bytes). Survivor space stores the objects that have survived the garbage collection of the Eden space. |
| SurvivorSpaceBefore | long | Survivor space before garbage collection (in bytes). Survivor space stores the objects that have survived the garbage collection of the Eden space. |
