MS SQL module
mssql
The root field containing all MSSQL fields
database
The database that the metrics is being referred to
-
mssql.database.id -
Unique ID of the database inside MSSQL
type: long
-
mssql.database.name -
Name of the database
type: keyword
performance
performance metricset fetches information about the Performance Counters
-
mssql.performance.page_splits_per_sec -
Number of page splits per second that occur as the result of overflowing index pages.
type: long
-
mssql.performance.lock_waits_per_sec -
Number of lock requests per second that required the caller to wait.
type: long
-
mssql.performance.user_connections -
Total number of user connections
type: long
-
mssql.performance.transactions -
Total number of transactions
type: long
-
mssql.performance.active_temp_tables -
Number of temporary tables/table variables in use.
type: long
-
mssql.performance.connections_reset_per_sec -
Total number of logins started from the connection pool.
type: long
-
mssql.performance.logins_per_sec -
Total number of logins started per second. This does not include pooled connections.
type: long
-
mssql.performance.logouts_per_sec -
Total number of logout operations started per second.
type: long
-
mssql.performance.recompilations_per_sec -
Number of statement recompiles per second. Counts the number of times statement recompiles are triggered. Generally, you want the recompiles to be low.
type: long
-
mssql.performance.compilations_per_sec -
Number of SQL compilations per second. Indicates the number of times the compile code path is entered. Includes compiles caused by statement-level recompilations in SQL Server. After SQL Server user activity is stable, this value reaches a steady state.
type: long
-
mssql.performance.batch_requests_per_sec -
Number of Transact-SQL command batches received per second. This statistic is affected by all constraints (such as I/O, number of users, cache size, complexity of requests, and so on). High batch requests mean good throughput.
type: long
cache_hit
Indicates the percentage of pages found in the buffer cache without having to read from disk.
-
mssql.performance.buffer.cache_hit.pct -
The ratio is the total number of cache hits divided by the total number of cache lookups over the last few thousand page accesses. After a long period of time, the ratio moves very little. Because reading from the cache is much less expensive than reading from disk, you want this ratio to be high
type: double
page_life_expectancy
Indicates the number of seconds a page will stay in the buffer pool without references.
-
mssql.performance.buffer.page_life_expectancy.sec -
Indicates the number of seconds a page will stay in the buffer pool without references (in seconds).
type: long
-
mssql.performance.buffer.checkpoint_pages_per_sec -
Indicates the number of pages flushed to disk per second by a checkpoint or other operation that require all dirty pages to be flushed.
type: long
-
mssql.performance.buffer.database_pages -
Indicates the number of pages in the buffer pool with database content.
type: long
-
mssql.performance.buffer.target_pages -
Ideal number of pages in the buffer pool.
type: long
transaction_log
transaction_log metricset will fetch information about the operation and transaction log of each database from a MSSQL instance
space_usage
Space usage information for the transaction log
since_last_backup
The amount of space used since the last log backup
-
mssql.transaction_log.space_usage.since_last_backup.bytes -
The amount of space used since the last log backup in bytes
type: long
total

The occupied size of the log in bytes
type: long
-
mssql.transaction_log.space_usage.used.pct -
A percentage of the occupied size of the log as a percent of the total log size
type: float
