Cluster CPU Load
Measures 1-, 5-, and 15-minute CPU load averages as supplied by /proc/loadavg.
cpuLoad -w w1,w5,w15 -c c1,c5,c15
The load average is a count of jobs in the run queue that are either runnable or waiting for disk I/O. The warning and critical limits are expressed as floating point triples for 1-, 5-, and 15-minute load averages. The limits only make sense with respect to core count on the machine. For example, a limit of 1.0 on an 8-core machine translates into a load average of 8, meaning the run queue length is the same as the core count and the machine is considered fully loaded.

The detail section displays this information:
The following detail is an Actian Warehouse instance with 1 leader and 3 workers each, configured with 32 cores. Warning alarm thresholds are 2.0, 1.25 and 1.25 for the 1-, 5-, and 15-minute load averages, respectively. Critical alarm threshold is 4.0 for 1, 5, and 15 load averages. A warning alarm would be triggered if the 1-minute load average exceeds 64 (32 cores * 2.0) or the 5- and 15-minute load averages exceed 40 (32 cores * 1.5).
cpu_load > 2.0,1.25,1.25 -> Warning, > 4.0,4.0,4.0 -> Critical Load Average
