Node info and management > SHOW QUERIES

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_found represents the number of groups instead of individual matches.
- For GROUP N BY queries, total_found still represents the number of groups, regardless of the value of N.
total_relation: Indicates whether the total_found value is exact or an estimate.
- If Manticore cannot determine the precise total_found value, this field will display total_relation: gte, meaning the actual number of matches is Greater Than or Equal to the reported total_found.
- If the total_found value is exact, total_relation: eq will be displayed.
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).

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 also use the optional LIKE clause, which allows you to select only the variables that match a specific pattern. The pattern syntax follows standard SQL wildcards, where % represents any number of any characters, and _ represents a single character.

When the cost-based query optimizer chooses to use DocidIndex, ColumnarScan, or SecondaryIndex instead of a plain filter, this is reflected in the SHOW META command.

The index variable displays the names and types of secondary indexes used during query execution. The percentage indicates how many disk chunks (in the case of an RT table) or pseudo shards (in the case of a plain table) utilized the secondary index.

SHOW META can be used after executing a CALL PQ statement, in which case it provides different output.

SHOW META following a CALL PQ statement includes:

total - Total time spent on matching the document(s)
queries_matched - Number of stored queries that match the document(s)
document_matches - Number of documents that matched the queries stored in the table
total_queries_stored - Total number of queries stored in the table
term_only_queries - Number of queries in the table that have terms; the remaining queries use extended query syntax.

Using CALL PQ with a verbose option provides more detailed output.

It includes the following additional entries:

Queries failed - Number of queries that failed
Fast rejected queries - Number of queries that were not fully evaluated but quickly matched and rejected using filters or other conditions
Time per query - Detailed time for each query
Time of matched queries - Total time spent on queries that matched any documents

SHOW THREADS

SHOW THREADS [ OPTION columns=width[,format=sphinxql][,format=all] ]

SHOW THREADS is an SQL statement that displays information about all threads and their current activities.

The resulting table contains the following columns:

TID: ID assigned to the thread by the kernel
Name: Thread name, also visible in top, htop, ps, and other process-viewing tools
Proto: Connection protocol; possible values include sphinx, mysql, http, ssl, compressed, replication, or a combination (e.g., http,ssl or compressed,mysql)
State: Thread state; possible values are handshake, net_read, net_write, query, net_idle
Connection from: Client's ip:port
ConnID: Connection ID (starting from 0)
This/prev job time: When the thread is busy - how long the current job has been running; when the thread is idling - previous job duration + suffix prev
Jobs done: Number of jobs completed by this thread
Thread status: idling or working
Info: Information about the query, which may include multiple queries if the query targets a distributed table or a real-time table

The Info column displays:

Raw text of queries executed via the Manticore SQL interface
Full text syntax, comments, and data size for queries run through the internal Manticore binary protocol (e.g., from a remote Manticore instance)

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).

SHOW QUERIES

NOTE: SHOW QUERIES requires Manticore Buddy. If it doesn't work, make sure Buddy is installed.

SHOW QUERIES returns information about all currently running queries. The output is a table with the following structure:

id: Query ID that can be used in KILL to terminate the query
query: Query statement or a portion of it
time: Time taken on command execution or how long ago the query was performed (in this case, the value will include ago)
protocol: Connection protocol, with possible values being sphinx, mysql, http, ssl, compressed, replication, or a combination (e.g., http,ssl or compressed,mysql)
host: Client's ip:port

SHOW VERSION

NOTE: SHOW VERSION requires Manticore Buddy. If it doesn't work, make sure Buddy is installed.

SHOW VERSION provides detailed version information of various components of the Manticore Search instance. This command is particularly useful for administrators and developers who need to verify the version of Manticore Search they are running, along with the versions of its associated components.

The output table includes two columns:

Component: This column names the specific component of Manticore Search.
Version: This column displays the version information for the respective component.
