<div dir="ltr">Hi Sandy,<div><br><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">That said, I'd love to hear about headaches and failures of the older<br>
StackTach release and how people are using it, or hope to use it.<br></blockquote><div><br></div><div>We have two StackTach v2 environments, one of which has been running for almost 3 years. For that particular environment, it can be a bear to do queries, sometimes taking up to a few minutes. This is understandable with how the information is stored in the db. </div><div><br></div><div>Another issue we've seen is that the workers sometimes fail to reconnect to Rabbit after a WAN outage. The remedy for that is to restart the workers from a cron.</div><div><br></div><div>But other than that, it runs great. Our environments are definitely not at the same scale as, say, eBay or CERN, and so operating StackTach has been manageable.</div><div><br></div><div>We use StackTach only as a troubleshooting tool. If a user is having an issue, we'll bring up their event history and review their timeline. I think this alone makes it an invaluable tool.</div><div><br></div><div>I reviewed all of your StackTach v3 stuff the other week. At first glance, there's definitely a lot more moving parts than with v2, but after reading about each one, they all make sense. I'm looking forward to trying some of it out.</div><div><br></div><div>I'd be happy to talk more in Philadelphia if you'd like. :)</div><div><br></div><div>Thanks,</div><div>Joe</div></div></div></div></div>
