SQL Server 采集器采集 SQL Server waitstatsdatabase_io 等相关指标

配置

SQL Server 版本 >= 2008, 已测试的版本:

  • 2017
  • 2019
  • 2022

前置条件

  • 创建用户:

Linux、Windows:

USE master;
GO
CREATE LOGIN [datakit] WITH PASSWORD = N'yourpassword';
GO
GRANT VIEW SERVER STATE TO [datakit];
GO
GRANT VIEW ANY DEFINITION TO [datakit];
GO

Aliyun RDS SQL Server:

USE master;
GO
CREATE LOGIN [datakit] WITH PASSWORD = N'yourpassword';
GO
注意事项

注意,执行上述操作需要相应权限的帐号,否则可能会导致用户创建失败或者授权失败。

  • 自建的 SQL Server 需要具备 WITH GRANT OPTION、CREATE ANY LOGIN、CREATE ANY USER、ALTER ANY LOGIN 权限的用户,也可以直接使用具有 sysadmin 角色的用户或者 local 用户授权。
  • RDS for SQL Server 则需要使用高权限账号进行授权。

采集器配置

进入 DataKit 安装目录下的 conf.d/samples 目录,复制 sqlserver.conf.sample 并命名为 sqlserver.conf。示例如下:

[[inputs.sqlserver]]
  ## your sqlserver host ,example ip:port
  host = ""

  ## your sqlserver user,password
  user = ""
  password = ""

  ## Instance name. If not specified, a connection to the default instance is made.
  instance_name = ""

  ## Database name to query. Default is master.
  database = "master"

  ## by default, support TLS 1.2 and above.
  ## set to true if server side uses TLS 1.0 or TLS 1.1
  allow_tls10 = false

  ## connection timeout default: 30s
  connect_timeout = "30s"

  ## Metric name in metric_exclude_list will not be collected.
  metric_exclude_list = [""]

  ## parameters to be added to the connection string
  ## Examples:
  ##   "encrypt=disable"
  ##   "certificate=/path/to/cert.pem"
  ## reference: https://github.com/microsoft/go-mssqldb?tab=readme-ov-file#connection-parameters-and-dsn 
  #
  # connection_parameters = "encrypt=disable"

  ## (optional) collection interval, default is 10s
  interval = "10s"

  ## Set true to enable election
  election = true

  ## v2+ override all measurement names to "sqlserver_metric", default: v2
  ## If you want to use the old metric set, you can change it to "v1"
  measurement_version = "v2"

  ## configure db_filter to filter out metrics from certain databases according to their database_name tag.
  ## If leave blank, no metric from any database is filtered out.
  # db_filter = ["some_db_instance_name", "other_db_instance_name"]

  ## collect object
  [inputs.sqlserver.object]
    # Set true to enable collecting objects
    enabled = true

    # interval to collect sqlserver object which will be greater than collection interval
    interval = "600s"

  ## Database Monitoring (DBM) configuration
  ## DBM provides deep visibility into database performance by collecting query metrics, activity, and execution plans
  [inputs.sqlserver.dbm]
    # Set true to enable DBM metrics collection
    enabled = false
    # Maximum number of characters to collect from stored procedures (default: 500)
    stored_procedure_characters_limit = 500

  ## Config DBM metric (query metrics)
  ## Collects cumulative execution statistics of SQL queries aggregated by query signature, query plan hash, and database
  [inputs.sqlserver.dbm.metric]
    # Set true to enable collecting query metrics
    enabled = true
    # Collection interval for query metrics (default: 60s)
    collection_interval = "60s"
    # Maximum number of rows to collect from sys.dm_exec_query_stats (default: 10000)
    # This limits the initial query result size before aggregation
    dm_exec_query_stats_row_limit = 10000
    # Maximum number of queries to report per collection interval (default: 500)
    # Only the top N queries (sorted by derivative elapsed time) will be reported as metrics
    max_queries = 500
    # Lookback window in seconds for filtering queries (default: 300)
    # Only queries that executed within this time window (based on last_execution_time + last_elapsed_time) will be collected
    lookback_window = 300
    # Enable plan collection (default: true)
    plan_enabled = true
    # Plan object cache TTL (default: 1h)
    plan_cache_ttl = "1h"
    # Maximum runtime in seconds for plan collection (default: 30)
    # If collection takes longer than this, plan collection will be skipped
    max_run_time = 30

  ## Config DBM activity (current active queries)
  ## Collects information about currently executing queries and active sessions
  [inputs.sqlserver.dbm.activity]
    # Set true to enable collecting active query information
    enabled = true
    # Collection interval for activity metrics (default: 10s)
    collection_interval = "10s"
    # Maximum number of rows to collect from sys.dm_exec_sessions (default: 1000)
    dm_exec_sessions_row_limit = 1000

  ## Run a custom SQL query and collect corresponding metrics.
  #
  # [[inputs.sqlserver.custom_queries]]
  #   sql = '''
  #     select counter_name,cntr_type,cntr_value
  #     from sys.dm_os_performance_counters
  #   '''
  #   metric = "sqlserver_custom_stat"
  #   tags = ["counter_name","cntr_type"]
  #   interval = "10s"
  #   fields = ["cntr_value"]

  # [inputs.sqlserver.log]
  # files = []
  # #grok pipeline script path
  # pipeline = "sqlserver.p"

  [inputs.sqlserver.tags]
  # some_tag = "some_value"
  # more_tag = "some_other_value"

配置好后,重启 DataKit 即可。

目前可以通过 ConfigMap 方式注入采集器配置来开启采集器。

日志采集配置

Note

必须将 DataKit 安装在 SQLServer 所在主机才能采集日志。

如需采集 SQL Server 的日志,可在 sqlserver.conf 中 将 files 打开,并写入 SQL Server 日志文件的绝对路径。比如:

[[inputs.sqlserver]]
    ...
    [inputs.sqlserver.log]
        files = ["/var/opt/mssql/log/error.log"]

开启日志采集以后,默认会产生日志来源(source)为 sqlserver 的日志。

数据库监控 (DBM)

数据库监控(Database Monitoring,DBM)功能提供对 SQL Server 数据库性能的深度可见性,通过收集查询指标、活动会话和执行计划来帮助分析和优化数据库性能。

启用 DBM

[inputs.sqlserver.dbm]
  # 启用 DBM 功能(默认:false)
  enabled = true
  # 存储过程字符数限制(默认:500)
  stored_procedure_characters_limit = 500

查询指标 (Metric)

收集 SQL 查询的累积执行统计信息,按查询签名、执行计划哈希和数据库进行聚合。包含执行次数、CPU 时间、逻辑读取、物理读取、等待时间等,通过计算导数指标(两次采集之间的差值)来反映查询的实际执行情况。

注意:只有连续两个采集窗口都出现的查询才会上报指标。首次采集到的查询仅作为基线,不会上报指标。

[inputs.sqlserver.dbm.metric]
  # 启用查询指标采集(默认: true)
  enabled = true
  # 采集间隔(默认: 60s)
  collection_interval = "60s"
  # sys.dm_exec_query_stats 查询的最大行数限制(默认: 10000)
  # 这限制了聚合前的初始查询结果大小
  dm_exec_query_stats_row_limit = 10000
  # 每个采集间隔报告的最大查询数(默认: 250)
  # 按导数执行时间排序后,只报告前 N 个查询
  max_queries = 250
  # 查询过滤的回看窗口(秒,默认: 120)
  # 只收集在此时间窗口内执行的查询(基于 last_execution_time + last_elapsed_time)
  lookback_window = 120
  # 启用执行计划采集(默认: true)
  plan_enabled = true
  # 执行计划对象缓存 TTL(默认: 1h)
  plan_cache_ttl = "1h"
  # 执行计划采集的最大运行时间(秒,默认: 30)
  # 如果采集时间超过此值,将跳过执行计划采集
  max_run_time = 30

执行计划 (Plan):当 plan_enabled = true 时,会同时采集执行计划。

活动查询 (Activity)

收集当前正在执行的查询和活动会话信息。记录会话状态、等待事件、阻塞信息、SQL 文本(已脱敏)等,用于实时监控数据库的当前活动状态。

会话指标 (Session):基于活动查询数据,会自动生成会话指标。

连接指标 (Connection):独立查询数据库连接信息,按用户名、状态、数据库等维度统计连接数。

[inputs.sqlserver.dbm.activity]
  # 启用活动查询信息采集(默认: true)
  enabled = true
  # 活动指标采集间隔(默认: 10s)
  collection_interval = "10s"
  # sys.dm_exec_sessions 查询的最大行数限制(默认: 1000)
  dm_exec_sessions_row_limit = 1000

指标

以下所有数据采集,默认会追加全局选举 tag,也可以在配置中通过 [inputs.sqlserver.tags] 指定其它标签:

 [inputs.sqlserver.tags]
  # some_tag = "some_value"
  # more_tag = "some_other_value"
  # ...

sqlserver_metric

指标集包含 SQL Server server、performance、wait stats、database IO、schedulers、volume space、database size/files/backup 和 DBM (metric/session/connection) 相关指标,v2 版本统一
