Hello,
How can ifind out the exact query executed by the sensor?
Thanks,

Here's the underlying query for the Oracle Tablespace sensor:
SELECT MAX(
CASE
WHEN t.online_status = 'ONLINE'
THEN 0
WHEN t.online_status = 'SYSTEM'
THEN 1
WHEN t.online_status = 'RECOVER'
THEN 2
WHEN t.online_status = 'SYSOFF'
THEN 3
WHEN t.online_status = 'OFFLINE'
THEN 4
ELSE 100
END) online_status,
MAX(
CASE
WHEN t.status = 'AVAILABLE'
THEN 0
WHEN t.status = 'INVALID'
THEN 1
ELSE 100
END ) status,
SUM(t.maxbytes) - SUM(t.bytes) FREE,
TRUNC(100 * (SUM(t.maxbytes) - SUM(t.bytes)) / SUM(t.maxbytes), 12) free_perc,
SUM(t.maxblocks) - SUM(t.blocks) blocks_free,
TRUNC(100 * (SUM(t.maxblocks) - SUM(t.blocks)) / SUM(t.maxblocks), 12) blocks_free_perc,
SUM(t.bytes) used,
SUM(t.disk_bytes) disk_used
FROM
(SELECT a.tablespace_name,
a.file_name,
a.online_status,
a.status,
CASE
WHEN a.AUTOEXTENSIBLE = 'NO'
THEN a.BYTES
ELSE a.MAXBYTES
END maxbytes,
(SELECT a.BYTES - NVL(SUM(b.BYTES), 0)
FROM dba_free_space b
WHERE b.FILE_ID = a.FILE_ID
) bytes,
a.BYTES disk_bytes,
CASE
WHEN a.AUTOEXTENSIBLE = 'NO'
THEN a.BLOCKS
ELSE a.MAXBLOCKS
END maxblocks,
(SELECT a.BLOCKS - NVL(SUM(b.BLOCKS), 0)
FROM dba_free_space b
WHERE b.FILE_ID = a.FILE_ID
) blocks
FROM dba_data_files a
) t
WHERE t.tablespace_name = 'TABLESPACENAME';

Hi Support,
I'm using 19.2.50.2842 version.
Is this query still valid ?

Yes the query is still valid.
Kind regards,

What is the timeout in seconds for this query? Can it be increased?
We have added multiple Oracle Tablespace sensors, but someone of them time out. When the same query is run on the server locally, it takes more than a minute to display the results.

Hello Viswanathan,
The timeout for the Oracle Tablespace sensor is 5000ms. You can increase the metascan timeout if needed, for instructions on how to do this, please see this KB article.
