== Thread pool
|
|
|
|
The `thread_pool` command shows cluster wide thread pool statistics per node. By default the active, queue and rejected
|
|
statistics are returned for the bulk, index and search thread pools.
|
|
|
|
[source,shell]
|
|
--------------------------------------------------
|
|
% curl 192.168.56.10:9200/_cat/thread_pool
|
|
host1 192.168.1.35 0 0 0 0 0 0 0 0 0
|
|
host2 192.168.1.36 0 0 0 0 0 0 0 0 0
|
|
--------------------------------------------------
|
|
|
|
The first two columns tell your the host and ip of a node.
|
|
|
|
[source,shell]
|
|
--------------------------------------------------
|
|
host ip
|
|
host1 192.168.1.35
|
|
host2 192.168.1.36
|
|
--------------------------------------------------
|
|
|
|
The next three columns show the active queue and rejected statistics for the bulk thread pool.
|
|
|
|
[source,shell]
|
|
--------------------------------------------------
|
|
bulk.active bulk.queue bulk.rejected
|
|
0 0 0
|
|
--------------------------------------------------
|
|
|
|
The remaining columns show the active queue and rejected statistics of the index and search thread pool respectively.
|
|
|
|
Also other statistics of different thread pools can be retrieved by using the `h` (header) parameter.
|
|
|
|
[source,shell]
|
|
--------------------------------------------------
|
|
% curl 'localhost:9200/_cat/thread_pool?v&h=id,host,suggest.active,suggest.rejected,suggest.completed'
|
|
host suggest.active suggest.rejected suggest.completed
|
|
host1 0 0 0
|
|
host2 0 0 0
|
|
--------------------------------------------------
|
|
|
|
Here the host columns and the active, rejected and completed suggest thread pool statistic are displayed. The suggest
|
|
thread pool won't be displayed by default, so you always need be specific about what statistic you want to display. |
