BetterCPU is a highly customizable monitoring and control system for CPU and memory resources in shared server environments. You can use it to throttle individual users and process.
Control & Stability
- Guarantee fair resource access to all
- Prevent system crashes and congestion.
- Isolate limit-exceeding users and processes within one or more cgroup-based “jail cores” where they cannot affect other users or the total system.
- You determine jail and release thresholds for specific groups and individuals. When overuse ends, jailed users resume full system sharing and jail cores convert back into general use.
- Instead of waiting to jail certain system-slowing processes, you can kill them as they arise, including zombies, unauthorized processes, and those using too much memory.
Density & Profits
- Unused dedicated resources are automatically re-allocated. (This is the most efficient a system is capable of)
- Limit-exceeding users are sent to a “jail core” where they share that core's resources. In a packed jail, users are throttled. In a relatively empty one, users may be given even more resources than before they were jailed. This protects the masses while helping, when possible, those with higher demands.
- Users and programs can use swap space beyond their physical RAM memory usage limits.
- Double (2x) your customers per server as compared to any other product.
- More users per server no longer means higher risk of overuse and instability.
- More customers per server means more money for you.
- See in real time which users and processes use the most CPU
- See which users are exceeding limits
- See which admin-assigned groups users belong to
- See each user’s total number of running programs with UID, and more.
- See detailed system core information, including how much of each “jail core” each user or process is using.
- You have extensive logging options and the ability to create summaries for definable periods.
- You can define all settings in one configuration file so the same file can be used on any system without changes.
