The sqlite3_analyzer.exe binary is a command-line utility program that measures and displays how much and how efficiently space is used by individual tables and indexes with an SQLite database file. Example usage:
sqlite3_analyzer database.sqlite
The output is a human-readable ASCII text report that provides information on the space utilization of the database file. The report is intended to be self-explanatory, though there is some additional explanation of the various parameters reported toward the end of the report.
The output is also valid SQL. Most of the report text is contained within a header comment, with various SQL statements that create and initialize a database at the end of the report. The constructed database contains the raw data from which the report was extracted. Hence the original report can be read into an instance of the command-line shell and then the raw data can be queried to dig deeper into the space utilization of a particular database file.
The sqlite3_analyzer.exe program is a TCL program that uses the dbstat virtual table to gather information about the database file and then format that information neatly.
The following is sqlite3_analyzer output for an example places.sqlite database used by Firefox.

*** Definitions ***************************************************************
Page size in bytes
The number of bytes in a single page of the database file.
Usually 1024.
Number of pages in the whole file
The number of 32768-byte pages that go into forming the complete
database
Pages that store data
The number of pages that store data, either as primary B*Tree pages or
as overflow pages. The number at the right is the data pages divided by
the total number of pages in the file.
Pages on the freelist
The number of pages that are not currently in use but are reserved for
future use. The percentage at the right is the number of freelist pages
divided by the total number of pages in the file.
Pages of auto-vacuum overhead
The number of pages that store data used by the database to facilitate
auto-vacuum. This is zero for databases that do not support auto-vacuum.
Number of tables in the database
The number of tables in the database, including the SQLITE_SCHEMA table
used to store schema information.
Number of indices
The total number of indices in the database.
Number of defined indices
The number of indices created using an explicit CREATE INDEX statement.
Number of implied indices
The number of indices used to implement PRIMARY KEY or UNIQUE constraints
on tables.
Size of the file in bytes
The total amount of disk space used by the entire database files.
Bytes of user payload stored
The total number of bytes of user payload stored in the database. The
schema information in the SQLITE_SCHEMA table is not counted when
computing this number. The percentage at the right shows the payload
divided by the total file size.
Percentage of total database
The amount of the complete database file that is devoted to storing
information described by this category.
Number of entries
The total number of B-Tree key/value pairs stored under this category.
Bytes of storage consumed
The total amount of disk space required to store all B-Tree entries
under this category. The is the total number of pages used times
the pages size.
Bytes of payload
The amount of payload stored under this category. Payload is the data
part of table entries and the key part of index entries. The percentage
at the right is the bytes of payload divided by the bytes of storage
consumed.
Average payload per entry
The average amount of payload on each entry. This is just the bytes of
payload divided by the number of entries.
Average unused bytes per entry
The average amount of free space remaining on all pages under this
category on a per-entry basis. This is the number of unused bytes on
all pages divided by the number of entries.
Non-sequential pages
The number of pages in the table or index that are out of sequence.
Many filesystems are optimized for sequential file access so a small
number of non-sequential pages might result in faster queries,
especially for larger database files that do not fit in the disk cache.
Note that after running VACUUM, the root page of each table or index is
at the beginning of the database file and all other pages are in a
separate part of the database file, resulting in a single non-
sequential page.
Maximum payload per entry
The largest payload size of any entry.
Entries that use overflow
The number of entries that user one or more overflow pages.
Total pages used
This is the number of pages used to hold all information in the current
category. This is the sum of index, primary, and overflow pages.
Index pages used
This is the number of pages in a table B-tree that hold only key (rowid)
information and no data.
Primary pages used
This is the number of B-tree pages that hold both key and data.
Overflow pages used
The total number of overflow pages used for this category.
Unused bytes on index pages
The total number of bytes of unused space on all index pages. The
percentage at the right is the number of unused bytes divided by the
total number of bytes on index pages.
Unused bytes on primary pages
The total number of bytes of unused space on all primary pages. The
percentage at the right is the number of unused bytes divided by the
total number of bytes on primary pages.
Unused bytes on overflow pages
The total number of bytes of unused space on all overflow pages. The
percentage at the right is the number of unused bytes divided by the
total number of bytes on overflow pages.
Unused bytes on all pages
The total number of bytes of unused space on all primary and overflow
pages. The percentage at the right is the number of unused bytes
divided by the total number of bytes.
