Answer

There are two graph types based on graph template "GRID - Cluster/Host Available Memory". One type is the host level graphs for the individual hosts of the cluster, other at the cluster level - as mentioned below.

1. Host - GRID Available Memory

The Host - Grid Available Memory graph shows the available memory and swap on host abc-2, corresponding to the lsload output

  # lsload abc-2  HOST_NAME       status  r15s   r1m  r15m   ut    pg  ls    it   tmp   swp   mem  abc-2               ok  25.0  26.4  25.8 100%   0.0   0 57568 4860M  2.1G  3.6G  

The mapping is
Physical Memory - mem
Swap Memory - swp

2. Cluster - GRID Available Memory

The Cluster - Grid Available Memory graph shows average available memory and swap of all hosts in the cluster, excluding unavailable hosts

  # lsload  HOST_NAME       status  r15s   r1m  r15m   ut    pg  ls    it   tmp   swp   mem  abc-8               ok   0.1   0.0   0.2   2%   0.0   0  3e+5 8480M  1.7G  2.7G  abc-10              ok   0.1   0.1   0.0   1%   0.0   0 50432   11G  2.4G  3.6G  abc-3               ok   1.0   0.9   0.9  33%   0.0   0  2e+5   11G  896M  519M  abc-6               ok   1.3   0.6   1.7  17%   0.1   1    15 4536M    3G  865M  abc-4               ok   9.5   3.9   3.6 100%   0.0   0 57568 7644M  1.9G  3.4G  abc-2               ok  24.1  24.3  26.7 100%   0.0   0 57568 4848M  2.0G  3.5G  

The mapping is
Physical Memory - average(mem)
Swap Memory - average(swp)
