- It is possible to customise the listed information by passing a
- comma-separated list of field names to this option (the field list
- is currently undocumented), or to extend the default field list by
- prefixing the additional field list with a plus sign. By default,
- the node list will contain the following information:
-
- F
- a character denoting the status of the node, with '-' meaning an
- offline node, '*' meaning N+1 failure and blank meaning a good
- node
-
- Name
- the node name
-
- t_mem
- the total node memory
-
- n_mem
- the memory used by the node itself
-
- i_mem
- the memory used by instances
-
- x_mem
- amount memory which seems to be in use but cannot be determined
- why or by which instance; usually this means that the hypervisor
- has some overhead or that there are other reporting errors
-
- f_mem
- the free node memory
-
- r_mem
- the reserved node memory, which is the amount of free memory
- needed for N+1 compliance
-
- t_dsk
- total disk
-
- f_dsk
- free disk
-
- pcpu
- the number of physical cpus on the node
-
- vcpu
- the number of virtual cpus allocated to primary instances
-
- pcnt
- number of primary instances
-
- scnt
- number of secondary instances
-
- p_fmem
- percent of free memory
-
- p_fdsk
- percent of free disk
-
- r_cpu
- ratio of virtual to physical cpus
-
- lCpu
- the dynamic CPU load (if the information is available)
-
- lMem
- the dynamic memory load (if the information is available)
-
- lDsk
- the dynamic disk load (if the information is available)
-
- lNet
- the dynamic net load (if the information is available)
