Mercury

My Mercury EC2 site has been running very slow for the past few days. I enabled cloudwatch for a bit and it is showing high CPU usuage. My site typically doesnt have more then 5-10 authenticated users online at once.

Here is a graph http://img708.imageshack.us/img708/8926/picture1ptf.png

What is the best way to track down what is slowing everything down?

Also, the "Online Users" block doesnt show how many guests are online because of the caching I guess - any way to fix that or get a semi accurate number about how many users are connected but not logged in?

I am really new to running a server. Been experimenting with Pantheon. Everything works great, I have the vote up down module which also works except that when I vote and the ajax updates the number of votes, the page changes slightly, some things stop picking up local.css theming (i use a fusion based theme, acquia marina). This happens only in a few places on the page that i noticed: views external filters and the views pager... What/where could the issue be? what should I check?

Any help would be great, thanks!

hello,

this is probably silly question, but if I change the name of the primary db from "pantheon" to "my_site" will any of the update_pressflow/mercury scripts have problems?
i think no, but want to be sure.

thanks!

In following the wiki (http://groups.drupal.org/node/70268) to build a mercury instance, after running the following command (step 5 of the wiki)
sudo bcfg2 -vqed -p 'mercury-aws'
Configuration freezes. Using a second ssh session and restarting the mysql server appears to unfreeze the script however later steps in the configuration surrounding mysql seem broken. Not knowing enough about bcfg2 to understand what it's trying to do that's not working leaves me stumped.

If you see this when running /usr/local/bin/update_mercury.sh:

The issue appears to be how I updated 1.1 with code from trunk. The fix is to run the following commands (assuming you're running 1.1):

Hi
My site was just migrated from Drupal to Mercury today morning...however now the site seems to be crashing every few hours :-(

The culprit seems to be Varnish ..I keep getting the following error messages

Can someone guide me on how I can debug it?

The site is on Rackspace running on Ubuntu 10.04 LTS

I'm enjoying my pressflow/mercury installation very much on a Rackspace Lucid Lynx instance.

An interesting thing that I note is that the number of "guests" grows over time and seems to take up the available memory. Now, we're only talking a few hundred "guests," but I do not think they are real. Not willing to blame Pantheon, but has anyone any thoughts on this issue?

Thanks!

Since my very first post announcing this idea of "Project Mercury" over a year ago, we've been getting repeated questions about whether or not someone could "buy" this technology. Pantheon being an open-source project, the answer all along has been "not really."

Until today.

It brings me great pleasure to announce that my friends at Advomatic are now offering the high-performance "Mercury" stack on their existing/proven VPS hosting service. Greg and Aaron from the Pantheon team have been working with them to get it all set up, and I have to say it's looking pretty good!

There will almost certainly be more ways to get Pantheon hosting in time, but it's really exciting to have our first go-to provider, and I couldn't be more pleased to have that partner be Avomatic. I've deployed many clients with them over the past four years, and I trust their team to do an excellent job on the sysadmin front. They offer 24X7 support, 100% network uptime SLA's, and flexible hosting plans. So, if you've been watching the progress here, and waiting for an option to run Pantheon without having to go it alone, get in touch with Advomatic and see for yourself what all the fuss is about.
