Note: HP renamed the product called now HP operations manager way too many times. Also it is very inconsistent with using abbreviations. Here we will assume that the term "HP Operations manager" and abbreviations HPOM, OMU, and OVO mean the same thing :-)
The command opcmsg sends an event to HPOM server. It can run from a regular user account (does not require to be root or sudo to root).
The opcmsg command opcmsg can be issued by any user.
The even which is sent by opcmsg will be first interpreted by the HPOM Message Interceptor on the local Managed Node. Those messages are forwarded to and then processed within HPOM by so called Message Interface Policies. At least one policy of this type should be present on the node. Typically message does not go to operator console if no policy matched the message.
Typically there is generic opcmsg(1|3) policy that can be made to match the message delivery of which you are debugging, but you mileage may vary (especially if too zealous consultant configured your server ;-). Always check, this if message is not delivered. For general strategy of dealing with the case when message is not delivered see Message from opcmsg not reaching HPOM console
The opcmsg command is available on all servers with HPOM agent installed. It generate messages with the following most important customizable fields (there are many more):
The custom policy for handling these opcmsg messages can among other things:
opcmsg [ -help ] [ -id ]
[ severity=severity ]
[ msg_grp=msg_grp ]
[ node=node ]
[ service_id=service_id ]
[ -option variable=value ]*
Any unique prefix can be specified for the available options. Note that the prefix for the option severity is s while the prefix for the option service_id is ser.
This command will exit with value zero after successful message generation; in case of internal error, 1 will be returned and a descriptive text will be displayed on standard error. If a syntax respectively usage error has been detected, 2 will be returned in conjunction with explaining text on standard error.
The option -id returns only one message ID even if the message matched several message conditions and multiple messages were generated on operator console.
If you like to acknowledge such messages with opcmack(1) you have to use opcgetmsgids(1) to retrieve the message IDs from all message before you can acknowledge them.
The message group (msg_grp), the object, and the application parameter should not be longer than 32 bytes, because this is the maximum size HPOM can handle with these parameters.
Test if messages coming from the node
/opt/OV/bin/opcmsg s=critical o=test msg_g=OpC a=test msg_t="test"
Submit a normal message issued by the application OpenSpool with the related object laserq:
opcmsg appl=OpenSpool obj=laserq msg_t="More than 100 print requests waiting in queue"
Submit a critical message issued by the script diskwatcher.sh with the related object /usr/lib which belongs to the Message Group OS by default; the minimal unique prefix is used for the options:
opcmsg s=critical msg_g=OS a=diskwatcher.sh o=/usr/lib n=ovtest.bbn.hp.com msg_t="Only 5% of entire disk space still available!"
Submit a critical message issued by the script mailwatcher.sh with the related object root which belongs to the Message Group OS by default. Also the -option switch is used to pass the subject to the message interceptor.
opcmsg s=critical msg_g=OS a=mailwatcher.sh o=root msg_t="Received mail” -opt subject=cron -option sub- ject2="x.log y.log z.log"
