We are going to turn out jobs to want to take care of the task and to send a notification if it fails to verify any backup. Monitoring all backup and log history is cleansing if it's designed.

Verify the pub on each drive on all servers. If there is necessary variance in the pub from the day before, analyze the rationale behind the pub fluctuation and resolve if necessary. Generally, log files will grow due to monthly jobs. Automate through employment. The task runs for every one hour and reports any drive that is to the pub. We are going to vogue an SSRS report back to showcase and review the delta values.

Check for the unsuccessful jobs, investigate the cause, and resolve the problem. Native SQL notification alert sends a mail to DBA team, and jointly we are going to vogue a custom SSRS report that reports all failed/success job details with delta value.

That has information pull jobs, information update jobs, etc. All cleanup jobs run fine, employee tables, logs, history, backup files, etc.

Confirm all servers/databases unit up and running fine. Usually in Associate in Nursing Enterprise data surroundings Third-Party Tools unit wish to observe Servers (Ex: “What’s Up”). For info observance we are going to vogue a native SQL Server answer pattern T-SQL code and maintenance created, it runs min by min And email DBA team if it's incapacitated to connect to any of the information among the instance.

Regularly monitor and establish obstruction issues. We are going to vogue a procedure that endlessly runs on all PROD servers and notifies the DBA team of any obstruction, Long-running queries/transactions. Check Performance counters on all production servers and verify that every one counters unit among the normal variables. We are going to vogue an SSRS matrix report back to review the counters for every one hour. Throughout the day, periodically monitor the performance pattern of every System Monitor and DMV. Check the fragmentation and rebuild/ reorganize the indexes. We are going to use a native procedure that takes care of the task. Make sure all Stats Update/nightly chock full / Index make jobs unit completed with none issue.

Have a look at every SQL Server log and Windows logs. If you discover any strange issues, inform the network or storage teams. Most of the time we tend to discover Network connected or I/O connected issues. Check the centralized error logs if any.

Check the error logs for unsuccessful logins and inform the audit team if necessary. Security Logs – Review the protection logs from a third party answer or from the SQL Server Error Logs to visualize if you had a breach or a violation in one in all your policies.

High availableness or Disaster Recovery Logs – Check your high availableness and/or disaster recovery technique logs. depending on the solution (Log Shipping, Clustering, Replication, data Mirroring, CDP, etc.) merely|that you just} simply unit pattern dictates what should be checked. We can vogue a native scripts pattern T-SQL to watch Replication, Mirroring, Log shipping. Monitor log shipping and mirroring pattern the custom keep procs. In most environments, we tend to visualize third-party tools in observance Clusters, or we are going to vogue our own native scripts pattern Windows Batch Programming. PowerShell and T-SQL.
