About: CPUs Past Week

Displays the CPUs allocated to and contributed by EPs at this site.

CPUs Allocated: Total count of CPUs allocated to EPs running at this site.
CPUs Contributed: CPUs utilized by jobs running at this site.

About: Memory Past Week

Displays the memory allocated to and contributed by EPs at this site.

Memory Allocated: Total amount of memory (in GB) allocated to EPs running at this site.
Memory Contributed: Memory (in GB) utilized by jobs running at this site.

About: Disk Past Week

Displays the disk allocated to and contributed by EPs at this site.

Disk Allocated: Total amount of disk space (in GB) allocated to EPs running at this site.
Disk Contributed: Disk space (in GB) utilized by jobs running at this site.

About: BCUs Past Week

Displays the Basic Compute Units (BCUs) allocated to and contributed by EPs at this site. 1 BCU is defined as 1 CPU core, 4 GB of memory, and 4 GB of disk. Total BCUs are calculated based on the most constrained resource.

For example, if a site contributes the following:

2 CPU cores
16 GB of memory
16 GB of disk

Its BCU contribution would be 2 BCUs, since the CPU cores are the limiting factor.

About: Memory per CPU

Displays the ratio between memory and cpus allocated to and contributed by EPs at this site.

Memory per CPU - Allocated: Amount of memory (in GB) allocated to EPs running at this site for each CPU allocated to those EPs.
Memory per CPU - Contributed: Memory (in GB) utilized by jobs running at this site for each CPU utilized by those jobs.

About: Disk per CPU

Displays the ratio between disk and cpus allocated to and contributed by EPs at this site.

Disk per CPU - Allocated: Amount of disk (in GB) allocated to EPs running at this site for each CPU allocated to those EPs.
Disk per CPU - Contributed: disk (in GB) utilized by jobs running at this site for each CPU utilized by those jobs.

About: Groups Served per Day

Displays the count of different organizational units that have utilized resources at this site.

About: CPU (l), Memory (r), Disk (r) Allocated per Day

Displays the sum total of resources allocated by the site per day, multiplied by the duration for which they were allocated. For example, if 4 CPUs were allocated for 5 hours, that would contribute 20 CPU Hours to the total for that day.

About: Maximum Concurrent Resource-Limited Glideins Per Day

For each resource type, display the maximum percentage of running Execution Points (EPs) that were limited by that resource on a given day. Here, "limited" is defined as having over 90% of a resource allocated to the EP used by running jobs.

For example, if an EP has 16 GB of memory and jobs running on the EP occupy 15 GB of memory, then the EP would be considered memory-limited. If 8 of the 10 EPs running at the site were memory-limited, then the site would be 80% memory-limited at that time.

Values displayed are the maximum percentages observed on that day. If, at any point in the day, 90% of concurrently running EPs were CPU-limited, the value for that day would be 90%.

About: Running Execution Points Past Week

Displays the count of running execution points at this site.

About: CPU Allocation Percentage by Project

For the given time range (day, week, or month), display the percentage of total CPU allocation at the site used by each project that ran jobs at the site.
