Columns

Column	Type	Description
AddressIp	string	IP address of the node that generated the logging event.
_BilledSize	real	The record size in bytes
CassandraKey	string	Cassandra key.
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.
DroppedCrossNodeTimeout	int	The number of messages dropped due to cross node timeout in last 5000ms.
DroppedInternalTimeout	int	The number of messages dropped due to internal timeout in last 5000ms.
DroppedMessages	int	The number of messages dropped in last 5000ms.
DroppedMessagesType	string	The type of messages dropped in last 5000ms.
DurationMs	int	Duration.
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.
EventProduct	string	Product of the logging event, e.g. cassandra, dse, solr.
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.
_IsBillable	string	Specifies whether ingesting the data is billable. When _IsBillable is false ingestion isn't billed to your Azure account
Level	string	Severity level of the event, will be one of INFO, WARM, ERROR, or OFF.
LiveCells	int	The number of live cells.
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	The type of agent the event was collected by. For example, OpsManager for Windows agent, either direct connect or Operations Manager, Linux for all Linux agents, or Azure for Azure Diagnostics
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.
TenantId	string	The Log Analytics workspace ID
ThreadId	string	ID of the thread that generated the logging event.
ThreadName	string	Name of the thread that generated the logging event.
TimeGenerated	datetime	Date and time the record was created.
TombstonedCells	int	The number of tombstoned cells.
Type	string	The name of the table
UsedMemory	long	The amount of memory currently used (in bytes).
