HP XC System 3.x Software - Manual (Page 111)

Xtools Daemons
Xtools use the following daemons:
• apmond and clusmond
The apmond and clusmond daemons are included with the Xtools software and collect
enhanced statistics. The Xtools start these daemons when you run xclus or xperf using
default parameters if they are not already running.
The apmond daemon collects processor-specific data for an individual node and runs on
each node being monitored. Only one instance of apmond is needed per node.
The clusmond daemon aggregates data it collects from the apmond daemons. There is
generally one clusmond process on each node where a user is running xclus or xperf
(in HP XC clusters, there is one clusmond process on each login node where xclus or
xperf
is running).
The apmond and clusmond daemons are started by xinetd and are not in the user process
tree.
• mond and supermon
The mond and supermon daemons are included with the HP XC software and collect generic
statistics. The Xtools start these daemons when your run xcxclus or xcxperf using default
parameters.
The mond daemon collects generic data for an individual node and runs on each node being
monitored. Only one instance of mond is needed on a node.
The supermon daemon aggregates data it collects from the mond daemons. The Xtools start
supermon
as a child process under xcxclus or xcxperf.
By default, supermon runs on the login node. If you specify the -login-node option when
you start xcxclus or xcxperf, supermon runs on the LSF-HPC execution host.
