SHOW META

  1. SHOW META [ LIKE pattern ]

SHOW META is an SQL statement that shows additional meta-information about the latest query such as query time and keyword statistics. The syntax is:

SHOW META can show IO and CPU counters, but they will only be available if searchd was started with --iostats and --cpustats switches respectively.

SHOW META needs to run right after the query was executed in the same session. As some mysql connectors/libraries use connection pools, running SHOW META in a separate statement an lead to unexpected results like getting meta from another query. In these cases (and recommended in general) is to run a multiple statement containing query + SHOW META. Some connectors/libraries support o multi-queries on same method for single statement, other may require usage of a dedicated method for multi-queries or setting specific options at connection setup.

You can also use the optional LIKE clause. It lets you pick just the variables that match a pattern. The pattern syntax is that of regular SQL wildcards, that is, % means any number of any characters, and _ means a single character.

  1. SHOW META LIKE 'total%';

SHOW META and facets

When using faceted search, you can check multiplier field in SHOW META output to see how many queries were run in an optimized group.

SHOW META and query optimizer

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

The index variable lists the names and types of secondary indexes used while executing the query. The percent shows how many disk chunks (in the case of an RT index) or pseudo shards (in the case of a plain index) the secondary index was used on.

SHOW META for PQ tables

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

SHOW META after a CALL PQ statement contains:

  • Total - total time spent on matching the document(s)
  • Queries matched- how many stored queries match the document(s)
  • Document matches - how many documents matched the queries stored in the table
  • Total queries stored - number of queries stored in the table
  • Term only queries - how many queries in the table have terms. The rest of the queries have extended query syntax.
  • SQL

CALL PQ with a verbose option gives a more detailed output.

It includes the following additional entries:

  • Setup - time spent on initial setup of the matching process: parsing docs, setting options, etc.
  • Queries failed - number of queries that failed
  • Fast rejected queries - number of queries that were not fully evaluated, but quickly matched and rejected with filters or other conditions
  • Time per query - detailed times for each query
  • Time of matched queries - total time spent on queries that matched any documents

SHOW THREADS

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

SHOW THREADS is an SQL statement that lists all threads information about what they are doing at the moment.

It returns a table with following columns:

  • Tid: id assigned to the thread by the kernel
  • Name: thread name, you can also see this name in top, htop, ps and other unix tools to monitor thread’s statistics
  • Proto: connection protocol, possible values are sphinx, mysql, http, ssl, compressed and replication or combination (e.g. http,ssl or compressed,mysql)
  • State: thread state, possible values are handshake, net_read, net_write, query, net_idle
  • Host: ip:port of the client
  • ConnID: connection id (starting from 0)
  • Time: current job’s duration (in seconds, with microsecond precision) or uptime of the thread in case of format=all when the thread is idling
  • Work time: uptime of the thread
  • Work time CPU: effective CPU time (requires --cpustats)
  • Jobs done: how many jobs this thread has completed
  • Last job took: last job’s duration
  • In idle: whether the thread is idling now or when it was last idling
  • Info: information about the query, can have multiple queries in case the query is against a distributed table or a real-time table

Info column shows:

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

Maximum width of the Info column can be limited by specifying the columns=N option (notice the second row in the example table).

By default, queries are shown in their original format. When the format=sphinxql option is specified, the queries will be shown in SQL format regardless of protocol through which they were executed.

format=all displays all threads, otherwise idling and system threads are hidden (e.g. those busy with OPTIMIZE)

  1. SHOW QUERIES

SHOW QUERIES returns information about all the queries running now. It outputs a table with the following structure:

  • id: query id which can be used in KILL to terminate the query
  • query: query statement or a part of it
  • protocol: connection protocol, the possible values are sphinx , mysql , http , ssl , compressed and replication or combination (e.g. http,ssl or compressed,mysql )
  • host: ip:port of the client
  • SQL

SQL
