Monitoring NetTalk Web Servers - What do others do?

[Devan]

Hey all,

We are getting to the stage where we have quite a few NetTalk apps out in the wild now, with some of them being quite mission critical.  As is the case with software, things do tend to fail, and we are getting more and more calls from clients when their webservers crash.  Some are hosted 'in house' on their own server which we have remote access to, and some are hosted by us on Amazon EC2 instances.

I want to be a bit more proactive about this, and set up a monitoring system that can monitor all the sites that we have developed to alert us when a site goes 'offline', i.e. stops responding to HTTP requests.

Some of the online web monitoring services I have seen are quite expensive.  Anyone use a low cost or free monitoring system that they could recommend?

Here is the kicker - Anyone write a Clarion app using NetTalk WebClient that sits in the background and quietly polls a list of sites for a valid 'heartbeat'?  I am thinking that we will have to roll our own system here, but if anyone else has already done this and willing to share, it will save us from reinventing the wheel...

Thanks,
Devan

check out the Polling Example under the Nettalk web client folder - you could tweak this to send you emails etc for sites not responding.

Thanks for the heads up Kevin - appreciate it.

I completely forgot about that demo app that comes with NetTalk.  Might have a play with that.

In the meantime, I signed up for uptimerobot.com - seems to be pretty cool.  It's free for up to 50 sites, and provides 5 minute monitoring intervals.

When converting to C8 I found a possible hang - in ABC - which I've documented there as well. Not sure if it's the one you have, but maybe.
