re: Remote ServerAccess
Follow up question, Well what if you have a user that you want to give permission to from any computer in the domain. Such as user: mysqluser with READ|SELECT|UPDATE from anywhere in: mydomain.com But not from any other domain. Thanks, Eric Lamendola Slingo Inc.

Re: MySQL Monitoring Alerts
Hey, I noticed another response about tailing the log and looking for information in the err log which looks like a great solution. However, if you have an extra computer laying around, you can also set up a cron job with a shell script that connects to the server (via telnet or using a mysql client to connect) and checks the output. Then quickly disconnects so as not to tie up a connection. If the connection is refused or unavailable, then the server is not responding. You could even put in some extra lines in the script for checking more than once to see if it was a fluke the first time. This would be a little more real time and allows you to set the frequency in which you want to monitor the server. Plus, you could set the script to Email you if the server isnt working.

Basically I need a way to monitor MySQL to ensure it hasn't gone down. We are using MySQL as the backend of some important sites and need to ensure that if it does crash for whatever reason, an alert (email and SMS) is sent out to an engineer to resolve the problem. We are presently using a program known as NetSaint to monitor our services but it sometimes doesn't seem to be 100% reliable at detecting a MySQL error. Anyway, can anyone tell me a better way to monitor MySQL so that if it has any problems an oncall engineer can respond quickly. I'm sure this must be a common problem so there must be something out there already.

Re: 'mysqladmin shutdown' doesn't shut it down...
Hey, I thought you could just use mysqladmin refresh -pPASSWORD -- or mysqladmin reload -pPASSWORD To kickstart logging again?

I've been using MySQL-4.0.3 (on Slackware-8.0) for a week or so now, and have noticed that the command: mysqladmin shutdown -ppassword doesn't shut down all mysql processes.

I'm not sure whether this was a bug or just my lack of understanding, but anyway it worked so I used it... The script used to work with MySQL-4.0.1 and MySQL-4.0.2 but now I get processes hanging around, usually 'mysqld_safe' and 1 or 2 'mysqld' processes. This appears to happen whether I leave a client connected or not. Under previous versions, if I left a client running (eg mysqltop - accidentally of course), mysql would shut down and mysqltop would loose it's connection - which is what I had expected to happen. So I'm not sure whether mysql keeps running because there are client connections still open (MS Access sometimes doesn't disconnect properly, and we have 40 MS Access clients...). So ... Is this behaviour expected if clients are leaving connections open? Has this behaviour been changed intentionally since MySQL-4.0.2? Is this likely to cause a problem? I have had to kill the processes with kill -9. There is nothing in the transaction or error log at all. And I haven't noticed any data corruption yet.

Re: MySQL Monitoring Alerts
Mike, I totally agree. The log solution wasn't my idea though smile. No matter what language you write the script in, any type of Get some kind of response by throwing something against the server and seeing if it sticks response will get you the information you need. I set up a dummy account and use a simple shell with a mysqladmin status command. Works fine for me. This just lets me know whether the server is up or down. Your way would work well also, because if you have to get a data response, it would probably provide greater detail as to the status and response time of the server. If not - hey what do I know heh Eric Lamendola At 10:26 AM 9/10/02 -0500, mos wrote: Eric, Isn't letting an outside connection access to your log file a little dangerous? Why not create a dummy table with just one record in it, restrict it to read access only, then use your chron job on a remote computer to run a PHP/Perl script to access that record over the net. If it returns an error, then examine the error number to determine what the problem is. (Maybe the connection is down, or the database is down.) There may be better ways to do it but this should be more secure.

Re: MySQL eating processer
The question you should ask yourself is What is it that my site may be doing that is causing MySQL to spike so much? I came into a similar situation and found that there were 2 major things that were impacting the usage of the database. The first would be the database structure that you are using. The second would be how the site is accessing the database. Are you making multiple queries off of different tables at the same time? Are you opening connections and not closing them? Are you asking for a lot of information from the DB for EVERY page on your site? Is there information you could simply store in a cookie and not go back to the DB for more information every time? Think of it this way, with 100K impressions per day - with load balanced over the entire day is about 71 pages per minute. Chances are you have 1 or 2 Hammer pages which are just taxing the DB more than it can handle. We simply changed the DB structure to not include so many tables in each query and change the way in which information was polled. Hope this gets you in the right direction Eric Lamendola Slingo Inc.
