I'm intrigued by what Hive and Guardian claim to be able to do - and because one of my current providers doesn't support cloudlinux (they use a custom kernel) I was hoping to try them out.
Has anyone taken these products for a spin?
We've been using Hive/Guardian for the past few months. We've traditionally been a FreeBSD host when it comes to shared, but with lots of new goodies appearing on Linux (CloudLinux, CSF, 1H to name a few) we felt it was well worth testing the water.
We trialled CloudLinux for a while, and I must admit it did a very good job, however after going to the cPanel conference we discovered 1H and thought we'd take it for a whirl also for much the same reasons as you - we ran a number of servers on AppLogic, and so we couldn't modify the kernel. Initially we only tried Guardian, but it alone saved our bacon on several occasions on a a server that had some intermittent very high loads, enabling us to fully trace the issue and resolve it.
We were then tempted onto using Hive and Digits - and having these two is like a dream come true. It is quite simply stunning. From one central login we can view cpu usage on web, mysql and cron of all the cPanel accounts across all the servers its installed on - as well as the disk usage and inode count. It's fast, the interface is well designed, and it's provided us a great tool for upselling as we can easily point clients to the graphs in their cPanel to see how their usage compares with normal usage. I think the key differentiator from our perspective with CL was just how much data you had at your fingertips from all your servers - this is now crucial to how we manage our shared servers effectively.
The combination of Guardian, which helps to monitor and even start to resolve issue, and Hive, which provides the most incredible reports and management of resource intensive accounts, is something that once you try you won't look back from. We're now in the process of converting servers over from FreeBSD to Linux with 1H.
The team at 1H have been great too, they've incorporated countless new suggestions we've made, and really made the job of switching over to their products very easy. Can't recommend them enough, the servers we have installed it on so far just purr along!
