What "psmctd" & "registrar" are doing?

[Katsu39]

Hello all
I have heard the EMS process is requireing these daemon or process of below?
/usr/sbin/stm/uut/bin/sys/diagmond
/usr/sbin/stm/uut/bin/sys/diaglogd
/usr/sbin/stm/uut/bin/sys/memlogd
/usr/sbin/stm/uut/bin/sys/cclogd
/etc/opt/resmon/lbin/registrar
/usr/sbin/stm/uut/bin/sys/psmctd

I could understand the function most of them. but I couldn't understand what "psmctd" & "registrar" would been doing, perfectly?
Also, what will be happend if they aren't running?

Actually those 2 hadn't been running on our LAB machine, which is HP9000/L2000-36.

HP-UX: B.11.00.01 HP-UX Jananese Media
EMS: B7609BA A.03.20
OnlineDiag: B.11.00.14.14

Thanks
Katsu

Hello Katsu,
registar is a very important process in the EMS architecture. It is listener and routing process : receving monitoring request and transmit it to the correct monitors, and generate events with adapted protocol format (mail, snmp, etc). Shuting down this process makes EMS no more correctly running : you will have no more correcte notification !

PSMCTD is not so important : it manage the Status of your device. If you don't have any cluster or mirroring, psmctd is not necessary. Also, if you receive esm alert and do the appropriate job (change disk, etc), psmctd is not necessary.

See the ems & monconfig man to have more details.

Olivier.
