opcragt - remotely administer agent processes on HP Operations Manager managed nodes

News HP Operations Manager Usage Options Exit values Examples
opcagt Troubleshooting agents node groups Layout groups Humor Etc

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 opcragt remotely administers the agent processes running on the managed nodes  from the management server. If called without any option, opcragt returns the current status of all agent processes on the specified system(s). This command is only available on the HPOM management server and can be used only by root. This command will exit with value 0 after successful operation; otherwise the exit value will be set to 1 and an appropriate message will be displayed on stderr

Here is one example when the status request fails. Here the reason is the firewall is enabled on the node but port 383 was not opened:

# opcragt -status linux8.somewhere.com
Node linux8.somewhere.com:
Cannot get status information from node linux8.somewhere.com.  (OpC40-428)
Network communication problems occurred. (OpC40-427)

-------------------------------------------------------------------------------
 CTRL - CommunicationException:
-------------------------------------------------------------------------------
(ctrl-21) Communication error when executing 'Status' method.
 (bbc-42) Unable to connect to the OV Communication Broker. The connection error returned was: 
  (xpl-316) connect() to '10.20.10.8:383' failed.
   (RTL-239) Connection refused (OpC40-2130)
Failed.

NOTE: the ovcd and ovbbccb processes must be running on the managed nodes, otherwise the HPOM management server cannot access the agent processes remotely. Some functionality is only enabled if the config setting OPCRAGT_USE_THREADS is set to TRUE, as described below.

Options

Examples

Start all agent processes on system ‘sales’ and ‘opcagt.prod.your.com’: opcragt -start sales opcagt.prod.your.com

Stop all agent processes (except the ovcd and ovbbccb) on system 12.132.123.3:

opcragt -stop 12.132.123.3

Determine current status of all systems belonging to this HPOM environment:

opcragt -status -all

Distribute/update templates and monitors to/on system 12.132.123.3:

opcragt -distrib -templates -monitors 12.132.123.3

Distribute the Event Correlation templates to the management server itself:

opcragt -distrib -templates ‘$MGMTSV’

Force distribution of commands to all managed nodes in this HPOM environment:

opcragt -distrib -commands -force -all

Set the primary HPOM manager on all systems belonging to the HPOM node group hp_ux:

opcragt -primmgr -nodegrp hp_ux

Return the version number of the HPOM agent software that is currently installed on node ‘opcagt.prod.your.com’:

opcragt -agent_version opcagt.prod.your.com

Return the value of OPC_LE_SAVE_STATE configuration setting from eaagt namespace on node ‘opcagt.prod.your.com’:

opcragt -get_config_var eaagt:OPC_LE_SAVE_STATE opcagt.prod.your.com

Set the OPC_LE_SAVE_STATE configuration setting in eaagt namespace on node ‘opcagt.prod.your.com’ to the value ‘TRUE’:

opcragt -set_config_var eaagt:OPC_LE_SAVE_STATE=TRUE opcagt.prod.your.com

Reset the OPC_LE_SAVE_STATE configuration setting in eaagt namespace on node

opcragt -set_config_var eaagt:OPC_LE_SAVE_STATE= opcagt.prod.your.com

Get the installation time for all your managed nodes:

opcragt -get_config_var OPC_INSTALLATION_TIME -all

Get the bbc.http namespace settings for all your managed nodes:

opcragt -get_config_var bbc.http: -all

Tip: Pushing policies assigned to a group to a single node

There is a possibility to push policies assigned to a node group to a single node using opcragt command. This is very convenient option for testing.

opcragt -distib -templates -instrum <node>

Notes

If you want to distribute the nodeinfo file to a managed node, you must first create the file with the command opcsw -get_nodeinfo <nodename>, before you can distribute it with opcragt -distrib <nodename>.

After having set a configuration variable with -set_config_var, the agents must normally be restarted for the new values to take affect.

Some functionality is only enabled when setting OPCRAGT_USE_THREADS to TRUE (command ovconfchg -ovrg server -ns opc -set OPCRAGT_USE_THREADS TRUE) on the HPOM management server. In detail that’s:

The HPOM managed nodes are contacted in parallel (default is to use 50 threads, can be adapted via config setting OPCRAGT_MAX_THREADS). If OPCRAGT_USE_THREADS is not set, the agents are contacted serially.

Options -start, -stop, -status, -primmgr, -get_config_var, -set_con fig_var and -agent_version are handled multi-threaded, others are not.

Unreached agents are listed with their FQDN in the logfile /var/opt/OV/share/tmp/OpC/mgmt_sv/opcragt-<command_option>-failed.log Whereas <command_option> is one of the supported options for multithreading as listed above (status, start, stop, primmgr, ...). The next call with the same option overwrites the log output from the previous.

The -get_config_var mode to show complete namespaces is also bound to the config setting OPCRAGT_USE_THREADS TRUE.

[Feb 03, 2011] opcragt -distrib does not distribute scripts

Aug 29, 2006 | IT Resource Center forums

Thomas Higginson

Hello,

the opcragt -distrib -templates -monitors -commands -force <NODE> does not distribute monitor scripts for Tru64

My OVOU Version is OVOU 8.21 on IA.

On the target /var/opt/OV/bin/instrumentation remains empty but the ovpolicy -list shows the just distributes templates.
What is the source directory on the Server. The following source dir contain the scripts:
/var/opt/OV/share/databases/OpC/mgd_node/customer/hp/alpha/tru64/monitor
and
/var/opt/OV/share/databases/OpC/mgd_node/customer/hp/alpha/tru64/RPC_BBC/m
onitor

How can I configure the SOURCE directory for distribution for a dedicated Servertype?

Hello - Im trying to update the agent on the OML server but getting the below error. (I have installed the latest agents on he OML server to 08.60.501 agents (Linux only for now) which all went fine, but Im getting the below error, also nothing in the admin chapter 2 on how to upgrade the agent, I imagine its via the opcragt -distrib command, any one if this is correct:

Agent ERROR:

Create distribution data and inform agent...
Warning: HP Operations agent is potentially not installed on node mynode.com
(software-installed flag not set in the database). Continuing with
distribution data (OpC40-730)
Done.

The OML server has the old agent and its running ok - 08.60.005

Any idea's on how to update the agent and reslove this error

Pete

using the admin gui I re-installed the agent and now its running the 08.60.501 agent but I still get the same Warning...

Goran Koruga

Hello.

Run this command:

opcsw -installed "node"

Regards,
Goran
