Script to montior ErrorLogs every 3 hours.

,

This script monitors your errorlogs every 3 hours for the past 3 hours. It notifies you by email for all types of errors and by pager for all critical errors with severity type > 16. Saves lot of time when you have to monitor several servers every day 24x7.
Run this script on a dedicated centralized SQL Server for better performance. Read the instructions mentioned in the script before installing it.

/* ---------------------------------------------------------------------------------------------------- *//* Instructions:Read the instructions below before executing this scripts. *//* ---------------------------------------------------------------------------------------------------- *//* Script Name:ErrorLogCheck.SQL        *//* Owner:Bodhayan K. Sharma*//* Created On:August 09, 2002*//* ---------------------------------------------------------------------------------------------------- *//* Purpose:The purpose of this script is to monitor the errorlogs of all the       *//*SQL Servers every three hours from a central database server.          *//*Email is sent as soon as an error is encountered and page is sent for   *//*Severity greater then 16.*//*This script should be installed only on SQL Server 2000 but it can      *//*monitor version 7 also.*//* ---------------------------------------------------------------------------------------------------- *//* Pre-requisites:1. Setup a SQL 2000 that will be monitoring all the other sql servers.  *//*:2. SQL Server services should be running under domain user account*/  
/*:3. Setup SQLMail to receive email notification about the errors*//*               :4. Create a database called 'SQLHelpDesk' to store the objects created  *//*:   by this script.  *//*:5. Search SQLDBA@emailaddress.com in this script and replace it with *//*:   your email add.*//*:6. Contact your pager provider to activate the email feature on your*//*   pager if this feature is required.
/* ---------------------------------------------------------------------------------------------------- *//* Execution:Press Ctrl+E to execute this scripts.*//* ---------------------------------------------------------------------------------------------------- *//* Post Execution:1. Populate the serverlist table with the name of the servers that needs*//*:   to be monitored. For IPAddress if SQL is installed as a named *//*:   instance then the ipaddress values should be ipaddress\instancename. *//*:   Populate IsSupported and IsRunning with Y.*//*:2. Populate the contacts table.*//*:3. Populate the pager number as 8001234567@skytel.com*//*:4. Publish SQLAlerts table to view the alerts on a webpage*//*:5. Use view_showerrormessage or view_showcriticalerrros to view errors  *//*:6. Recycle the errorlogs of the servers being monitored every day if *//*:   sossible so that this script can function more effeciently.*//* ---------------------------------------------------------------------------------------------------- *//* Objects Created:Tables:-(serverlist,errorlog,errorloghistory,sqlalerts,contacts,*//*:paginghistory)*//*:Triggers:-(trigins_paginghsitory)*//*:Stored Procedures:-(usp_executeerrorlogcheck,usp_errorlogcheck,*//*:usp_insertsqlalerts,usp_sendpagetoprimary)*//*:Views:-(view_showerrormessage,view_showcriticalerrors)*//* :Jobs:-(ExecuteErrorLogCheck) - runs every three hours*//* ---------------------------------------------------------------------------------------------------- *//* Modified By:Bodhayan K. Sharma*//* Modified On:August 09,2002*//* Modification Details :                                                                     *//* ---------------------------------------------------------------------------------------------------- */
