The easiest way to view high-level information about your Manticore node is by running status in the MySQL client. It will display information about various aspects, such as:
- Current version
- Whether SSL is in effect or not
- Current TCP port/Unix socket
- Uptime
- Number of threads
- Number of jobs in queue
- Number of connections (
clients) - Number of tasks being processed currently
- Number of queries executed since the start
- Number of jobs in queue and number of tasks, normalized by the number of threads

--------------SHOW STATUS [ LIKE pattern ]SHOW STATUS is an SQL statement that presents various helpful performance counters. IO and CPU counters will only be available if searchd was started with the --iostats and --cpustats switches, respectively (or if they were enabled via SET GLOBAL iostats/cpustats=1).

13 rows in set (0.00 sec)SHOW META [ LIKE pattern ]SHOW META is an SQL statement that displays additional meta-information about the processed query, including the query time, keyword statistics, and information about the secondary indexes used. The syntax is:
The included items are:
total: The number of matches that were actually retrieved and sent to the client. This value is typically limited by the LIMIT/size search option.total_found:- The estimated total number of matches for the query in the index. If you need the exact number of matches, use
SELECT COUNT(*)instead of relying on this value. - For queries with
GROUP BY,total_foundrepresents the number of groups instead of individual matches. - For GROUP N BY queries,
total_foundstill represents the number of groups, regardless of the value ofN.
- The estimated total number of matches for the query in the index. If you need the exact number of matches, use
total_relation: Indicates whether thetotal_foundvalue is exact or an estimate.- If Manticore cannot determine the precise
total_foundvalue, this field will displaytotal_relation: gte, meaning the actual number of matches is Greater Than or Equal to the reportedtotal_found. - If the
total_foundvalue is exact,total_relation: eqwill be displayed.
- If Manticore cannot determine the precise
time: The duration (in seconds) it took to process the search query.keyword[N]: The n-th keyword used in the search query. Note that the keyword can be presented as a wildcard, e.g.,abc*.docs[N]: The total number of documents (or records) containing the n-th keyword from the search query. If the keyword is presented as a wildcard, this value represents the sum of documents for all expanded sub-keywords, potentially exceeding the actual number of matched documents.hits[N]: The total number of occurrences (or hits) of the n-th keyword across all documents.index: Information about the utilized index (e.g., secondary index).

17 rows in set (0.00 sec)SHOW META must be executed immediately after the query in the same session. Since some MySQL connectors/libraries use connection pools, running SHOW META in a separate statement can lead to unexpected results, such as retrieving metadata from another query. In these cases (and generally recommended), run a multiple statement containing both the query and SHOW META. Some connectors/libraries support multi-queries within the same method for a single statement, while others may require the use of a dedicated method for multi-queries or setting specific options during connection setup.

You can limit the maximum width of the Info column by specifying the columns=N option.
By default, queries are displayed in their original format. However, when the format=sphinxql option is used, queries will be shown in SQL format, regardless of the protocol used for execution.
Using format=all will show all threads, while idling and system threads are hidden without this option (e.g., those busy with OPTIMIZE).
