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?
