title: Performance logging/monitoring API/product
body: <p>I'm not sure how to categorize this question, so let me just explain what I would like and hopefully it will make sense.</p>
  
  <p>I'm after a product (with an API) which I can send different numbers to with tags, and it will take care of all the monitoring/logging stuff.</p>
  
  <p>So for example, say I have a program that downloads a file from a website every 10 seconds.  I would like to monitor how long each of these downloads is taking.  It is quite easy in my application to time how long it takes.  I would now like to send this number and tag (e.g., tag='download time', value = '1.234') to a 3rd party product.  The 3rd party product will now store this value/tag for me.  The product will have a website I can go to, and configure a bunch of things.  So in this example, I could setup an alert like "if 'download time' > 5 send me an email".  I could also visit a website, and view a graph of the logged values and maybe some random statistics (e.g., how often the value has been in the warning/error zone).</p>
  
  <p>I think that's about it.  Sure it wouldn't be <em>too</em> hard to do this myself, but I'm no web designer and it'd end up looking pretty ugly.  The more user friendly this kind of product is the more willing users will be to look at the data and actually monitor stuff. </p>
  
  <p>Does such a service exist?</p>
