itochecker - a utility for HP Operations Manager Health checking

itochecker is a Born shell script that produces various reports about configuration of HPOM management server. It also attempts to identify configuration items which may cause problems. itochecker should be used on a regular basis for proactive determination of HPOM problems as well as troubleshooting tool when a particular problems occurs.

While a useful 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:

It is an unsupported large shell script (around 7K lines), but HP continues to maintain the tool and welcomes feedback on problems as well as enhancement requests. The logic is simple that the code has some educational value. The main structure is a set of procedures each of which performs one particular check:

check_mgmt_sv()
check_DNS()
check_required_patch()
check_nslookup()
check_system_file_perm()
check_kernel()
check_opcinfo()
check_distrib_dir()
check_cluster_info()
check_ito_files()
check_opcinfo_opcerror()
check_server_processes()
check_permissions()
check_and_init_db()
check_num_audit_files()
check_supp_unmat_cond()
check_templ_not_group()
check_msg_node_grp()
check_oracle_diskspace()
check_node_groups()
check_mpi_templ()
check_agent_processes()
check_templ_assigned()
check_ns()
check_if_pingable()
check_node_snmp()
check_licenses()
check_ito_op_dir()
check_java_files()
check_svcnav_files()
check_services_and_loggings()
check_pre_req()

This is strictly reporting tool. Internally it is uses regular HPOM commands such as: 

/opt/OV/bin/OpC/opcragt -status -all
/opt/OV/bin/OpC/opcragt -agent_version -all
/opt/OV/bin/OpC/opcragt -get_config_var eaagt:OPC_PRIMARY_MGR -all
/opt/OV/bin/OpC/opcragt -get_config_var sec.core.auth:MANAGER -all

It doesn’t make any changes on the system it checks, but you can try remotely restart agent for nodes that have problem only reported only in  "Agent State" column (WARNING or ERROR):

  Nodename                                 Node state   Agent State  Cert. State  Config State    Overall
  lux26.dmz2.firma.com                        OK           WARNING      OK           OK           WARNING

Default report files created are

They are created in the output directory, which is set to /tmp/ito_rpt by default. The output directory can be changed by setting the ITOCHECKDIR environment variable before calling the itochecker / itosend scripts.

If run without options it presents interactive menu. To run the tool in non-interactive mode you need to supply at least one option. For example to check HPOM , 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).

Syntax

itochecker [ -1234567 [-l] [-x] [-t] [-a] [-m] [-s nodename] ]

Options

Return Value

In case errors were detected during the check, itochecker returns the following value:

1 -- An error occurred.

Files

  1. /opt/OV/contrib/OpC/itochecker -- The main script
  2. /opt/OV/contrib/OpC/itochecker.conf -- Configuration file, used by itochecker it can be used to change settings, e.g. Kernel Parameters,...
  3. /opt/OV/contrib/OpC/itosend -- Script to send the packed itochecker output file per email to HP Operations support
  4. /opt/OV/contrib/OpC/agent_platform.conf -- Config file, used by itochecker to decode machine numbers to platform paths and detect the machine types of managed nodes.
  5. /tmp/ito_rpt/ITO.rpt -- Plain text report file
  6. /tmp/ito_rpt/report.html -- html report index (there additional multiple file sin the directory referenced by this index)

Examples

Invoke itochecker and presents a user menu:

itochecker

Invoke itochecker and check nodes:

itochecker -5

Checks the HPOM environment, the database, the node stroppy and tars all output files to one tar file:

itochecker -235 -t -s stroppy

Re: itochecker, node check problemOptions

Could anyone help me understand what itochecker is doing when it checks nodes, and why our node reports are empty?

Goran Koruga 04-20-2010 09:17 PM

Hello.

Are you referring to the "-5" option of the 'itochecker' tool?

It uses opcragt, nslookup, SNMP checks and the likes.

If it's about the option '-3', then it uses SQL queries to get a list of nodes from the OPC_NODES table.

In any case, itochecker is a shell script so it should be trivial for you to find out what it's doing.


OK here's what I recommend.

1. Copy itochecker to /var/tmp and run 'chmod 755 /var/tmp/itochecker'

2. Edit the script, find function "do_nodes_check" and make its start look like so:

do_nodes_check()
{
set -x

We only added 'set -x' to assist with debugging.

3. Run it:

/var/tmp/itochecker -5 >/var/tmp/chk.txt 2>&1

4. Look in the file "/var/tmp/chk.txt" and find a section similar to this (note that your values will be different):

+ + wc -l /tmp/opc.22782/node_list
+ awk {print $1}
NUMNODES=6
+ + date +%H %M %S

What does it set NUMNODES to?

Below that it should say "Checking 6 node(s)" - again, the number will be different in your case. After this it shall process all the nodes it has found previously.

It uses the SQL query I used before and you said it lists a lot of nodes, so that part looks OK. The NUMNODES value should be he same number as is the number of rows returned by the SQL query you used before.

Regards,
Goran
