Hello Ilya,
I got it.
If the table is created through JDBC, the metric data will be 0.
Only when the CREATE TABLE statement is executed through SqlFieldsQuery,
the data will be counted.
I think it's a bug,Ilya, can you confirm again?

Hello!
I can see some values on the server when executing SqlFieldsQuery on
the same server:
| cache.foo.QueryCompleted | 3 |
|
| cache.foo.QueryExecuted | 3 |
|
| cache.foo.QueryFailed | 0 |
|
| cache.foo.QueryMaximumTime | 350 |
|
| cache.foo.QueryMinimalTime | 101 |
|
| cache.foo.QuerySumTime | 665 |
|
I can also see them on client, but you need to a) specify
ClientConnectorConfiguration on client node with non-default port, b)
connect to that port with JDBC, and c) Enable metrics exporter SPI on
the client node. Then I can see the same, after running
SqlFieldQuery's on client:
| cache.foo.QueryCompleted | 3 |
|
| cache.foo.QueryExecuted | 3 |
|
| cache.foo.QueryFailed | 0 |
|
| cache.foo.QueryMaximumTime | 269 |
|
| cache.foo.QueryMinimalTime | 20 |
|
| cache.foo.QuerySumTime | 424 |
|

Hello Ilya,
if use sqlline execute sql,the feedback result of the following
statement is correct.
SELECT * FROM sys.metrics WHERE name LIKE 'sql%' ORDER BY name;
I used SqlFieldsQuery again to do the above tests, and the results
were all 0. I think there may be a issue in this.

Hello!
I think these metrics will be gathered for
ScanQuery/SqlFieldsQuery executed via native Java Query API, but
they will not be gathered for statements executed via JDBC.
One obvious reason is that Java Query API's queries are bound to
a specific cache. JDBC query is not bound to specific cache: JDBC
query may operate on zero or more caches. We could map these
queries back to participating caches, but I don't see that we do
that.
You could still use sql.queries.user. metrics:
SELECT * FROM sys.metrics WHERE name LIKE 'sql%' ORDER BY name;

Hello Ilya,
The test method is as follows:
Start 2 nodes on the localhost.
Use the CREATE TABLE statement to create a table;
Use the COPY command to load some data;
Access to cluster through sqlline;
Execute select count (*) from T;
Execute select * from sys.metrics WHERE name LIKE '%cache.T%';
At this time, you will find that the relevant data are all 0,
but the value of OffHeapEntriesCount is still correct.
If you use sqlline to access another node, the result is the
same.
The configuration file to start the cluster is as follows:

Hello!
These values are per-node, as far as I know. Is it possible
that you have connected to a node which does not handle any
queries (as reducer, anyway)?

Hi,
We found that SYS.METRICS View some data is always 0,
such as
QueryCompleted,QueryExecuted,QuerySumTime,QueryCompleted,QuerySumTime
and QueryMaximumTime. This is a bug? Or what
configuration is needed? Or
the related functions have not been implemented yet?
