MSSQL Integration using KloudMate Agents

this document describes the steps to collect mssql metrics and logs using kloudmate agents by configuring the appropriate receivers within the agent’s collector configuration the sqlserver receiver collects detailed performance metrics from a microsoft sql server instance it can gather data either through windows performance counters (when running on windows) or by directly connecting to the database and executing queries performance counters are only available on windows hosts to capture mssql logs, the sql query receiver is used it allows you to execute custom sql queries and convert the results into metrics or logs that can be forwarded to kloudmate in this setup, the hostmetrics receiver , sqlserver receiver , and sqlquery receiver are all configured within the kloudmate agent to collect and send telemetry to kloudmate prerequisite mssql server must be installed and running kloudmate agent installed on the mssql host (see agent installation for https //docs kloudmate com/linux agent and https //docs kloudmate com/windows agent ) ensure that you run the agents as an administrator to collect all performance counters for metrics step 1 configure the microsoft sql server receiver server receiver along with the hostmetrics receiver to hostmetrics receiver to scrape the mssql metrics and sql query receiver sql query receiver along with the filelog receiver filelog receiver to pull required logs navigate to the kloudmate platform and log in to your account go to settings > agents section here you can view all installed agents access configuration settings for each agent review the default configurations provided by kloudmate to edit an agent's collector configuration select the desired agent click the actions menu (or agent action tab) choose collector configuration a text editor ui will open, allowing you to edit the agent’s yaml configuration directly within the platform extensions health check pprof endpoint 0 0 0 0 1777 zpages endpoint 0 0 0 0 55679 file storage create directory true receivers otlp protocols grpc endpoint 0 0 0 0 4317 http endpoint 0 0 0 0 4318 hostmetrics collection interval 30s scrapers cpu metrics system cpu utilization enabled true load cpu average true memory metrics system memory utilization enabled true filesystem metrics system filesystem usage enabled true system filesystem utilization enabled true disk {} network {} processes {} sqlserver collection interval 30s username \<username> #use the username password \<password> #use the secure password server 0 0 0 0 port 1433 metrics sqlserver database count enabled true sqlserver database io enabled true sqlserver database latency enabled true sqlserver database operations enabled true sqlserver processes blocked enabled true sqlserver resource pool disk throttled read rate enabled true sqlserver resource pool disk throttled write rate enabled true sqlquery/upmetrics driver mssql datasource "sqlserver //\<user> \<password>@localhost 1433?database=kloudmate test\&encrypt=disable" #modify the username and password queries \# query collect sql server uptime as a metric \ sql | select sqlserver start time, datediff(minute, sqlserver start time, getdate()) as minutes uptime from sys dm os sys info; metrics \ metric name sqlserver uptime minutes value column minutes uptime attribute columns \["sqlserver start time"] static attributes dbinstance mydbinstance filelog include \# ensure the path is appropriate for your server's operating system uncomment the line below if the server is running windows \ /var/opt/mssql/log/errorlog \# 'c \program files\microsoft sql server\mssql\log\errorlog ' storage file storage multiline line start pattern ^\d{4} \d{2} \d{2} \d{2} \d{2} \d{2}\\ \d{2} retry on failure enabled true \# query to show client connections and ip sqlquery/connection driver mssql datasource "sqlserver //\<user> \<password>@localhost 1433?database=kloudmate test\&encrypt=disable" storage file storage queries \ sql | select c session id, c client net address as client ip address, s host name, s login name, s program name, s login time, s last request start time, s last request end time, 'mssql client log' as log source from sys dm exec connections as c join sys dm exec sessions as s on c session id = s session id where s last request start time > $$1 order by s last request start time asc; tracking column last request start time tracking start value "" #
