EMS Directories and Files

EMS ﬁles are located in /etc/opt/resmon and /opt/resmon. The following is a description of ﬁles and directories that might help you determine the cause of some problems:

/etc/opt/resmon/config

A ﬁle that sets the restart interval for monitor persistence.

/etc/opt/resmon/dictionary

A directory that contains resource dictionaries for the various monitors. The disk monitor resources are listed in diskmond.dict and the cluster, network, and system resource monitors are in the mibmond.dict. If you were writing your own monitor, the dictionary would go in this directory.

/etc/opt/resmon/lbin

A directory where all the monitor daemons live. Some important daemons in the directory:

p_client restarts any failed monitors based on information in the config ﬁle.

registrar handles passing monitoring requests to the correct monitors, and sending qualifying events out in the correct protocol format.
