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 :-)
HPOM provides several utilities to assist with troubleshooting in the /opt/OV/contrib/OpC directory. One utility, the itochecker, provides an overall check of your OS and HPOM environment.
While a useful Born shell script with the unique and very educational set of checks (studying the code gives you some additional insights about HPOM), it is badly maintained and have a serious weaknesses some of them stemming from the use of Born shell and others from the lack of maintenance:
The itochecker report is a useful tool to pinpoint existing problems and should be used as the first step in evaluating the HPOM server health. After invocation it displays the following menu:
Usage: itochecker [1234567lxtshma] itochecker 09.00.160 - an expert utility from the HP Operations Manager Support Select one or multiple check groups: 1 - System environment check 2 - HPOM environment check 3 - General database che 4 - Database/node verification 5 - Nodes check 6 - JavaGUI/SvcNavigator check 7 - Performance checks Select specific options if requested: l - Check licenses, when checking nodes (check 5) x - Check via snmp, when checking nodes (check 5) t - tar and zip output files to one file, including cluster, core, opcinfo/error, ito_op information s - check only a specified node (only effective, if Nodes check was chosen) h - Help m - Send messages to the HPOM Message Browser a - run the checks 1-6 with options t and m q - Quit Type one or multiple numbers/characters and press
to start the checks (any sequence is allowed) Options?
Read the man page for usage details. The primary areas of interest are any categories that show errors.
To run the tool in non-interactive mode you need to supply at least one option.
Itochecker is a very useful tool for checking the health of the agents. To check the agents please run:
Here is an example of the report
Nodes Overview Nodename Node state Agent State Cert. State Config State Overall ss2.mynet.firm.com OK WARNING OK OK WARNING
Nodename Node state Agent State Cert. State Config State Overall ldb48.somewhere.com OK ERROR ERROR OK ERROR
To check HPOM environment, you can run:
It will generate the report in both text and HTML formats. The HTML is structured as index page and multiple sections (one for each category of checks).
For checking the server combining the first four option ( -1234 ) is the best, for example:
/opt/OV/contrib/OpC/itochecker -1234 SYSTEM ENVIRONMENT CHECK: Name Resolution System Info Checking hardware model ... Checking memory, swap, software versions ... Checking free disk space ... Checking total disk space ... Number Of Processes / System Load System file permissions OS Patches Finished System environment check HPOM ENVIRONMENT CHECK: HPOM Version/Package & ECS Designer Server Processes Kernel Parameters HPOM Patches Installed HPOM filesets HPOM Binaries: Version and Patches HPOM Libraries: Version and Patches Diskspace in DB and HPOM directories Pending Data in Distribution Directory Policy and Config Files Cluster Information core File Information config settings and error log files Checking opcerror Elements in Server Queues Elements in Agent Queues Critical file permissions and ownership HP Operations Manager Components Finished HPOM environment check DATABASE CHECK: Database Information Database Queries Finished database check HPOM DATABASE CHECK: Agent Entries in DB / Agent Entries in Filesystem Diskspace in Oracle Directory usage: grep [-E|-F] [-c|-l|-q] [-bhinsvwx] -e pattern_list...

1. Run the following commands.
Exclude monitoring of “genaanosrvr”, “httpd”, and “ovctrl” because their status is unknown in normal situation.
Make a list of all daemons (the first column) for which the State column (third column) is not “RUNNING”. Then email “OVSTATUS problem - <list of daemons> not running on `hostname`” to the list of recipients.
Sample (Good) output of ovstatus
root@ds0demt2# ovstatus -c
Name PID State Last Message(s)

2. Run the following command.

Sample “Good” output of ovcroot@ss2: # ovc agtrep OV Discovery Agent AGENT,AgtRep (5770) Running coda OV Performance Core COREXT (5767) Running opcacta OVO Action Agent AGENT,EA (5759) Running opcmona OVO Monitor Agent AGENT,EA (5773) Running opcmsga OVO Message Agent AGENT,EA (5700) Running opcmsgi OVO Message Interceptor AGENT,EA (5762) Running ovbbccb OV Communication Broker CORE (3989) Running ovcd OV Control CORE (3979) Running ovconfd OV Config and Deploy COREXT (4014) Running
3. Run the following command.
Make a list of daemons name (the first column) for which the status is not “Running” (the last column). Then email one message that “OPCAGT Problem - <list of daemons> not running on `hostname`” to the list of recipients.
