monitoring

What I want to do is to monitor a table in mysql which is always auto-updated by a sms gateway. The script should be monitored continuously and as soon as there is a new entry in the table, a php script ritn to perform further operations should be triggered. How do I achieve this? I've done exactly this lots of times using cron. So your php script starts by seeing if there is a new entry, and then does what it needs to do if there is. If there's nothing to work on, it just exits immediately. One thing to bear in mind is that if the script takes a long time to run, you want to make sure your

I want to create a Dashboard on each server to show it's health and the results of some daily processing. I plan to hook up shell scripts and Python programs to collect the data. Instead of writing a web-based interface, I thought it would be good to use a python based web dashboard that could render the results in various business user and manager friendly formats. What are my options to do this? I am primarily interested in Python RedHat Linux, but other platforms are interesting too. I'm also open to Perl and Ruby based solutions especially if the plugins can be language neutral. Have you

In the context where I want to capture the stdout of a process in a file but still want to have this output displayed in the terminal I can choose between script and tee . In this context, are these tools essentially equivalent or is there a – possibly subtle – reason to prefer one over the other? The programs script and tee are designed for different purposes: script -- make typescript of terminal session tee -- pipe fitting Important differences between script and tee are: script transmits the exit status of the process it supervises, while tee , being a filter, does not even know about it.

I have a Google Alert, which I set to be delivered as an RSS feed as-it-happens But is polling that RSS feed the only way to get RSS feed or is there a way to get notified from Google alert as the feed is published from Google? (say through a webservice, etc) derekvanvliet Google Alerts feeds support PubSubHubbub which essentially pushes notifications of updated content to you if you register on the feed's hub. They're using the hub at pubsubhubbub.appspot.com More info on PuSH here: http://code.google.com/p/pubsubhubbub/ Sounds like you want a PubSubHubBub for your alerts 来源： https:/

I'd like to be able to get a notification from a network printer when it physically finishes printing a page (and/or the entire job). This is going to be used in an app I'm writing for print management via web, and since users get charged per-page, and the charge shouldn't go down before the page actually completes. I'm not sure whether this requires writing a driver, some kind of plug-in or whether a client app will do. I am flexible with my platform, since my client isn't written yet, so I'd like to hear about any suitable solution in either Windows or Linux, in any programming language
