Simple checklist for troubleshooting policies:

  1. Was policy assigned to the node?
  2. Was the most recent version of the policy distributed to the node ?
  3. What is the date of the corresponding XML file. Is content of XML file corresponds to your expectations? Look at the content of folder
    /var/opt/OV/datafiles/policies

    For example:

    configsettings/
    configsettings/a1b6413e-f15e-11d6-83d0-001083fdff5e_data
    configsettings/a1b6413e-f15e-11d6-83d0-001083fdff5e_header.xml
    monitor/
    monitor/708b199a-4420-71e0-1e7f-0ac90d6a0000_data
    monitor/708b199a-4420-71e0-1e7f-0ac90d6a0000_header.xml
    msgi/
    msgi/8046512c-ec43-71df-06a5-0ac90d6a0000_data
    msgi/02cf4ecc-7a9d-71e0-1e7f-0ac90d6a0000_header.xml
    msgi/02cf4ecc-7a9d-71e0-1e7f-0ac90d6a0000_data
    msgi/7f9e236c-1f4c-71e0-1e7f-0ac90d6a0000_header.xml
    msgi/8046512c-ec43-71df-06a5-0ac90d6a0000_header.xml
    msgi/4b4d977e-1161-71e2-09e7-0ac91d6a0000_data
    msgi/7f9e236c-1f4c-71e0-1e7f-0ac90d6a0000_data
    msgi/4b4d977e-1161-71e2-09e7-0ac91d6a0000_header.xml
    sched/
    sched/3bb9a62a-1ea6-71e2-09e7-0ac91d6a0000_data
    sched/3bb9a62a-1ea6-71e2-09e7-0ac91d6a0000_header.xml	

    For example: 

    you can find your policy using grep, for example
    grep "tick_generator" /var/opt/OV/datafiles/policies/msgi/*
    SYNTAX_VERSION 6
    
    ADVMONITOR "tick_generator"
            DESCRIPTION "generating ticks each minute, if the server is alive"
            INTERVAL "1m"
            SCRIPTTYPE "Perl"
            INSTANCEMODE  SAME
            MAXTHRESHOLD
            SEVERITY Warning
            MSGGRP "Dev"
            OBJECT "ticker"
            PROGRAM "ticker"
              DESCRIPTION ""
              MONPROG "/usr/local/bin/montest.pl"
            SUPP_UNM_CONDITIONS
              DESCRIPTION "tick_generator"
              CONDITION_ID "86363298-067a-71e2-09e7-0ac91d6a0000"
              CONDITION
                OBJECT
                  SCRIPT "#PARAMETERS START
    
    #PARAMETER param1 STRING DEFAULT \"unknown\" VALUE \"$HOSTNAME\"     CAPTION \"param1\"
    my $param1;
    $param1 = \"$HOSTNAME\";
    
    #PARAMETER param2 STRING DEFAULT \"unknown\" VALUE \"$UPTIME\"     CAPTION \"param2\"
    my $param2;
    $param2 = \"$UPTIME\";
    
    #PARAMETERS END
    $timestamp=`date +"%y%m%d_%H%M"`;
    `echo "[ $timestamp ] got tick @ARGV" > /tmp/opcmon_tick_test_log.txt`;
    exit 1
  4. Are all the necessary instrumentation files distributed to the node? Are their versions correct on the node.
  5. Trace the opcmona process... you can see exactly what it is doing and why. The trace is not too ugly to look at.
    ovconfchg -ns eaagt -set OPC_DBG_EXCLUDE_AREA MUX,QM,MEMQ,MUX/CV
    ovconfchg -ns eaagt -set OPC_TRACE_AREA MSG
    ovconfchg -ns eaagt -set OPC_DBG_PROCS opcmon,opcmona ovconfchg -ns eaagt -set OPC_TRC_PROCS opcmon,opcmona ovconfchg -ns eaagt -set OPC_TRACE TRUE

    This will show you the opcmon processes running, ( hopefully it really does run more than once ) then it will put the result into the queue, then opcmona will pull it out make some decisions about it and then forward to opcmsga. Concentrate on the opcmona parts ( grep opcmona /var/opt/OV/tmp/OpC/trace ) and see why it is doing what it is doing and with what parameters opcmon is invoked.

    You can use a single command to set trace on the management node:

    ovconfchg -ns eaagt \
       -set OPC_TRACE TRUE -set OPC_TRACE_AREA ALL,DEBUG\
       -set OPC_TRACE_TRUNC FALSE \
       -set OPC_TRC_PROCS opcmsg,opcmsgi,opcmsga\
       -set OPC_DBG_PROCS opcmsg,opcmsgi,opcmsga\
       -set OPC_DBG_EXCLUDE_AREA MUX,QM,MEMQ,MUX/CV

    To disable the agent trace settings:

    ovconfchg -ns eaagt -set OPC_TRACE FALSE

    After that look at the file /var/opt/OV/tmp/OpC/trace
     

  6. Is trace result correspond to your expectations?

    For example the following fragment crearly shows that OV system vairable <MGMTSV_KNOWN_MSG_NODE_NAME>  is missing $ sign (should be <$MGMTSV_KNOWN_MSG_NODE_NAME>) :

    10/25 10:18:01.029 opcmsga(15825:-1118177504)[init]: Out_txt echo  "<MGMTSV_KNOWN_MSG_NODE_NAME>"  > /tmp/ticker.log
    10/25 10:18:01.029 opcmsga(15825:-1118177504)[actn]: Local action request created: Auto c86d1798-1eae-71e2-04b0-0ac936350000 'echo  "<MGMTSV_KNOWN_MSG_NODE_NAME>"  > /tmp/ticker.log'
    10/25 10:18:01.029 opcmsga(15825:-1118177504)[debug]: SIG: Blocking signal 0.
    10/25 10:18:01.030 opcmsga(15825:-1118177504)[debug]: SIG: Unblocking signal 0.

[ Sep 24, 2012 ] Re several opcmon from same Perl script

08-06-2012 | HP Communities

Hello Gurus,

I'm stomped on this one. I have a Perl script that checks unsuccessful attempts on user IDs and when above 5, sends an opcmon like this one:

/usr/lpp/OV/bin/opcmon GenID_Attempts=$strresult[1] -option USER_ID=$userid

Fairly simple?! Yes. But..

When I have more than one ID that passes the threshold, the monitor only returns the last opcmon sent by the script. When I run the script manually with the exact same command line entered in the Monitor Program entry, both alerts show up in my browser. I cannot determine why I'm not getting the second (or first actually) alert when it is the monitor that triggers the script. I'm pretty sure that where I'm wrong is I gotta find a way to tell the monitor that these are two different thresholds, but I haven't found that option. I thought it was "Process each instances separately" but no. That's why I'm kinda baffled now.

I'm using OML 9.10.220.

Thanks

Marco

Hi Marco,

Can you check if the second message which has come to console has duplicate count in it?

how many matching rules you have in your policy?

I have Diskmonitoring configured on AIX node in the same way and i get all the alerts processed by opcmona.

So i dont think that any additional configuration is required.

if possible upload your script.

-KAKA- 1

Marco Santerre (Honored Contributor)

I have checked the duplicate count and no there is not a duplicate count on the alert.

There is only one rule on my monitoring policy.

Like I mentioned, I know we have had several occurences of scripts and monitors sending many opcmon from the one script and never had any issues, yet this one seems to behave differently.

ovconfchg -ns eaagt -set OPC_DBG_EXCLUDE_AREA MUX,QM,MEMQ,MUX/CV
ovconfchg -ns eaagt -set OPC_TRACE_AREA MSG
ovconfchg -ns eaagt -set OPC_DBG_PROCS opcmon,opcmona ovconfchg -ns eaagt -set OPC_TRC_PROCS opcmon,opcmona ovconfchg -ns eaagt -set OPC_TRACE TRUE

This will show you the opcmon processes running, ( hopefully it really does run more than once ) then it will put the result into the queue, then opcmona will pull it out make some decisions about it and then forward to opcmsga. Concentrate on the opcmona parts ( grep opcmona /var/opt/OV/tmp/OpC/trace ) and see why it is doing what it is doing, once you verify that opcmon is running multiple times.

I actually found the solution by trying something :

I added -object $user_id to differenciate between the various opcmon sent by the script.

And that worked.
