I'm looking for something (software or script) that will check online status of plenty of websites at once. For example I have over 100 websites and I want to check 4 times a day if they are all up or down. Ideally the software would also check if databases are ok because if MySQL server is down the websites show Database Error Message so they are not quite exactly dawn... but it matters. Any ideas if there is such software or script that will automatically do this job?
