type char(8) node type, such as ES40
maxmem int maximum memory available in megabytes
maxfree int maximum free memory available in megabytes
maxswap int maximum swap space available in megabytes
maxtmp int temporary file system space in megabytes
cpus 1–32 number of CPUs
cpus_reserved 0–32 number of CPUs reserved for OS services
elans int mask of Elan devices present
netid 0–255 physical network ID (if applicable)
configured 0 | 1 whether node is configured in or out
status char(16) current node status
runlevel char(16) UNIX run level

or upgrade (0).
The status field indicates the service level being provided by a node. Valid values are
shown in Table B.4. State changes are logged in the events table (see Section 10.2.6);
entries are keyed by class=node.
The runlevel may have one of the values shown in Table B.5.
The elans field is a mask of the Elan devices present in the node. It has one bit set for
each device. In previous releases, only device 0 was supported.

To enable the collection of these statistics, the node-statistics field in the
