HPOM and Agents Health Checks using itochecker

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 is weak in detecting network communication problems with the agent and its summary table does not have such a category. That's a serious weakness.
• Also if the node is disabled the itochecker  does not explicitly detect this state.

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.

Checking HPOM agents

 Itochecker is a very useful tool for checking the health of the agents. To check the agents please run:

/opt/OV/contrib/OpC/itochecker -5

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

NOTES: 

• itochecker  version 09.00.160 diagnoses "enabled firewall with blocked port 383" problem  incorrectly as certificate error:

  Nodename             Node state Agent State Cert. State Config State Overall
  ldb48.somewhere.com  OK         ERROR       ERROR       OK           ERROR

• For more information about troubleshooting HPOM agents see Troubleshooting HPOM agents

Checking HPOM server

To check HPOM environment, you can run: 

/opt/OV/contrib/OpC/itochecker -2

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

• 20120326 : Perl Script that must run on HPUX11i server ( Perl Script that must run on HPUX11i server, Mar 26, 2012 )

Old News

[Mar 26, 2012] Perl Script that must run on HPUX11i server

Perl Script to monitor OV Platform: HPUX 11i Perl Version: 5.8.8. This idea of using baseline lit of processes for the server and the agent can be implemented in many different ways but it is definitely worth implementing.

1. Run the following commands.

# ovstatus

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)

OVsPMD 3166 RUNNING -

ovsessionmgr 3202 RUNNING Initialization complete.

ovwdb 3203 RUNNING Initialization complete.

ovuispmd 3295 RUNNING Initialized. 0 ovw clients registered.

ovtrapd 3288 RUNNING Initialization complete.

ovactiond 3289 RUNNING Initialization complete.

ovalarmsrv 3290 RUNNING Initialization complete.

pmd 3204 RUNNING Initialization complete.

genannosrvr - unknown (Does not communicate with ovspmd.)

httpd - unknown (Does not communicate with ovspmd.)

ovtopmd 3287 RUNNING Connected to native database "openview".

netmon 3296 RUNNING Initialization complete.

ovrequestd 3208 RUNNING Initialization complete.

ovctrl - unknown (Does not communicate with ovspmd.)

ovoacomm 3369 RUNNING Open Agent Service Server Initialization Complete.

opc 3390 RUNNING OVO Server Initialization Complete.

ovas 3370 RUNNING Initialization complete.

ovdbcheck 3292 RUNNING Connected to embedded database.

2. Run the following command.

# ovc

Make a list of daemons name (the first column) for which the status is not "Running" (the last column). Then email one message that "OVC Problem - <list of daemons> not running on `hostname`" to the list of recipients.

Sample "Good" output of ovc

agtrep      OV Discovery Agent                  AGENT,AgtRep (5770)   Running

ovconfd     OV Config and Deploy                COREXT       (4014)   Running
	

3. Run the following command.

# opcagt

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.

Sample "Good" output of opcagt

[127] root@ss2: # opcagt
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
Message Agent is not buffering.
	

4. Run the following command.

# opcsv

Make a list of daemons name (the second column) for which the status is not "running" (the last column). Then email one message that "OPCSV Problem - <list of daemons> not running on `hostname`" to the list of recipients.

Sample "Good" output of opcsv

root@ds0demt2# opcsv

if [[ $COUNT -lt 2 ]]

then

TA_MESSAGE="Telalert Processes are not running on `hostname`"

Send TA_MESSAGE to the List of Recipients

#

if [ `/opt/telalert/bin/telalert -show|wc -l` -ge 200 ]

then

TA_MESSAGE="FYI - Telalert Queue is Full. Automatic action will clear th

e queue."
