![]() ![]() If you do not have the resources, you can use one of your regular SQL servers as monitor server. Having a separate monitor server is not technically necessary. The linked servers need to have the option 'RPC out' set to 'True'. This implies having/choosing a monitor server with linked server access to all SQL servers whose error logs you want to monitor. You can define general exclusions (all servers, any time) or specific ones (only server X, or only server Y between 02:15 and 04:30).įinally, all remaining log entries for all servers combined are emailed in an easy-to-read tabular layout:īelow, setup is described for a multi-server situation. The basis of the filter is an ‘exclusion table’: a table with (parts of) messages you want to exclude. You probably want to be warned only about the unexpected ones, so a stored procedure is included which filters the results in the holding table. Many error messages are informational and others may be ‘expected’ in your environment. In case of identical messages, the message is logged only once, but the number of occurrences is recorded. It can do this for a number of SQL servers and will check older versions of the server log if the current version contains less than 24 hours of messages (this can happen when SQL is restarted or the log is reinitialized). The core of the solution is a stored procedure which uses XP_READERRORLOG to retrieve the last 24 hours of messages from a given SQL server. It is designed to run from a monitor server and poll linked servers but can also be used ‘locally’ and run on a per-server basis. The solution described below requires no external tooling and may help you not to miss out on important error messages and failed logins. Alternatively, see the guide Advanced FTP/SFTP scripting for examples of checking script results (including XML log parsing) using more powerful languages and the guide to Interpreting XML log for advanced scripting using C# language.Do you scan the SQL Error Logs of all your SQL production servers on a daily basis? Do you monitor the logs for failed logins? Without tools, this can be a challenge because the bulk of the log messages can usually be ignored. If you require checking results of each command individually, you should better use the WinSCP. ini=nul /log=example.log /script=example.txtĪ similar error handling is used in the batch file template that WinSCP can generate for you. ![]() You should also make the batch file indicate a result in its exit code, particularly if it is called from some parent system (for example SSIS). Once you find out what was the result of the script, you can perform any action you like: print a message, send an email, etc. Save and inspect output of the script.Check exit code of WinSCP (exit code is the only relevant and reliable way to check if script completed successfully).See Conditional processing in automation for a more complex example and Advanced FTP/SFTP scripting for examples of script generation using more powerful languages. See more hints on using parametrized batch file. Now you can run the batch file like (supposing you have saved it to file upload.bat): Rem Delete the temporary script del script.tmp Rem Execute the script /ini=nul /script=script.tmp Rem Generate a temporary script to upload %1 ( echo open mysession For complex tasks, you will need to use some scripting language, such JScript or VBScript from Windows script host or PHP or Perl.įollowing example shows batch file that takes filename on command line and generates WinSCP script file to upload that file to remote server: For simple tasks you can use built-in Windows scripting functionality from batch file (. To automate that, make a wrapper script file. You can also use environment variables in the script.Īlternatively, you can generate new script file each time. ini=nul /script=script.tmp /parameter // c:\myfile.txt NET assembly.įor simple modifications, you can pass the variable parts of the script from command line: For example you may want to operate it with different file each time.įor tasks involving more complex modifications, conditional processing, loops or other control structures, you should better use the WinSCP. You may want to modify the script automatically.
