Features summary

BL Manager’s WHM plug-in for cPanel makes using BetterLinux easy:

In General:

  • Intuitive user interface with a simple tab-row-column layout with input boxes and on/off switches.
  • Set and control group limits for CPU, Disk I/O, network bandwidth, and memory.
  • Start, restart, or stop any BetterLinux service with a click.
  • Automatically verifies that your configuration syntax is correct before turning on services.

Specific settings:

  • Set maximums for the number of processes users can run and the amount of time they can run them.
  • Use default settings or customize all throttling settings per cPanel package.
  • For any package, choose what percentage of a CPU core each user may use, how many concurrent processes are allowed, and how much RSS memory may be used before initiating a log entry or repeating kill command. The log/kill option is also available when sshd, crond, httpd, and chroothttpd run longer than allowed.

I/O controls:

  • Apply global as well as per-package settings. Also create separate settings for each device mount point within a package.
  • Global “seek balancing” (optional) enables automatic throttling of seek-heavy processes across the whole system.
  • Global “auto scaling” (optional) makes unused I/O bandwidth available to defined users beyond their standard individual limits while keeping the system's global disk utilization below a defined target.
  • Auto scaling (optional) also works at the per-package level, giving unused package resources to other package members beyond standard limits. Auto scaling turns every package into package+ service at no cost to providers. And by observing users of surplus I/O, you can see who may be fit for a higher package.
  • Installs automatically with version 1.0.4-1 and newer

Where to find it:

You’ll see BL Manager at the bottom of cPanel's WHM menu under Plugins.
