Description |
Measurement Unit |
Interpretation |
| batchSizeAvg |
Indicates the average number of bytes sent per partition per-request. |
MB |
|
| batchSplitRate |
Indicates the average number of batch splits. |
Splits/sec |
|
| bufferAvailableBytes |
Indicates the total amount of buffer memory that is not being used (either unallocated or in the free list). |
MB |
|
| bufferExhaustedRate |
Indicates the average number of sent record, that are dropped due to buffer exhaustion. |
Number |
A very low is required for this measure.
|
| bufferTotalBytes |
Indicates the maximum amount of buffer memory the client can use (whether or not it is currently used). |
MB |
|
| bufferpoolWaitRatio |
Indicates the fraction of time an appender waits for space allocation.
| Number |
|
| compressionRateAvg |
Indicates the average compression rate of record batches and it is defined as the average ratio of the compressed batch size over the uncompressed size.
| Number/sec |
|
| connectionCloseRate |
Indicates the closed connections.
| Connections/sec |
|
| connectionCount |
Indicates the current number of active connections.
| Number |
A very high value is required for this measure.
|
| connectionCreationRate |
Indicates the new established connections.
| Connections/sec |
|
| failedAuthenticationRate |
Indicates the connections for failed authentication.
| Connections/sec |
Ideally, the value of these measures should be zero.
|
| failedReauthentication |
Indicates the connections for failed re-authentication.
| Connections/sec |
Ideally, the value of these measures should be zero.
|
| ioTimeNsAvg |
Indicates the average length of time for I/O per select call.
| Seconds |
|
| ioWaitTimeNsAvg |
Indicates the average length of time the I/O thread spent waiting for a socket ready for reads or writes.
| Seconds |
|
| metadataAge |
Indicates the age of the current producer metadata being used.
| Seconds |
|
| waitingThreads |
ndicates the number of user threads blocked waiting for buffer memory to enqueue their records.
| Number |
