Check_as400 was created for Nagios to monitor IBM System i.

Easy monitoring of all key indicators.

Nagios Exchange - Check_AS400

The following I have completed the development of options:

AJ = Number of active jobs in system.
CJ = Check to see if job is in the system.
CJS [status ] [noperm]
= Check to see if job is existing in Subsystem and has this status.
Job checking can be controlled by :
status = any other status goes to critical
noperm = don't go to critical if job is not in the system
NOTE: if JobStatus is set, it has highest Priority
JOBS = Number of jobs in system.
CJM = Check the temporary storage used of job.
JOBQ = Number of jobs in JOBQ.
CPU = CPU load.
CPUC = CPU load, Consider Current processing capacity. (CPU used * VP nums / cpuBase).
NOTE: Specify , EX: You want use 3 CPU only, but VP use more than 3.
CPUT = Top CPU used job. The total processing unit time used by the job
Specify job name, ex: *ALL or QZ* or QZDASOINIT
US = Percent free storage
ASP = Check ASP used
DISK = Check DISK Status.
DB = DB utilization. (Not available after V6R1)
DBFault = Pool DB/Non-DB Fault
LOGIN = Check if login completes.
MSG = Check for any unanswered messages on msg queue
Any unanswered messages causes warning status.
OUTQ = Check outq files, writer and status. No writer, or
status of 'HLD' causes warning status. This default
behavior can be modified with the following options:
nw = Don't go critical when no writer
ns = Don't warn if status is 'HLD'
nf = Ignore number of files in queue
NOTE: threshold values are used on number of files
SBS = Check if the subsystem is running.
NOTE: specify as library/subsystem
PRB = Check if the problem was identified.
---------- VISION MIMIX ----------
MIMIX = Check MIMIX Data Group Unprocessed Entry Count, Transfer definition, RJ link state.
---------- Rocket iCluster ----------
ICNODE = Check for any Inactive or Failed Node status.
ICGROUP = Check for any Inactive or Indoubt Group status.
ICSWTCHRDY = Check for multiple conditions for switch readiness.

-SSL
Use SSL connection.
-d
Be verbose (debug)
NOTE: Needs to be one of the first arguments to work
-D
Be verbose and dump screen outputs (debug)
NOTES: Needs to be one of the first arguments to work
When things are not working, use this flag, redirect the output to a file and send it to me!

Notes:
-CPU, DB and US threshold's are decimal, JOBS, JOBQ and OUTQ are integers.

Install Note

======================================================================
* Modify your $NAGIOS_PATH/.as400 with the correct user and password.
* Modify chech_as400 with the correct java path.
* Set NAGIOS user profile Display sign-on information *NO
- CHGUSRPRF USRPRF(NAGIOS) DSPSGNINF(*NO)
Initial program to call . . . . *NONE
Initial menu . . . . . . . . . . MAIN
* Nagios user may need to use IBM default sign-on display file
Or change nagiso user to other subsystem description to use system default display file
a.Use the Change Subsystem Description (CHGSBSD) command.
b.Specify the display file on the SGNDSPF parameter. System default is QSYS/QDSIGNON
c.ADDWSE SBSD(SBSLIB/SBSD) WRKSTN(QPADEVxx*) AT(*SIGNON)

* Avoid the massive entries log
CHGJOBD JOBD(NAGIOSJOBD) LOG(4 00 *MSG)

* Use SSL connection
Must add CE to JAVA, for EX:
keytool -import -trustcacerts -keystore /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.85.x86_64/jre/lib/security/cacerts -storepass changeit -noprompt -alias xxxx_ce -file /xx/xxx/XXXX.cer

* If you upgrade cum-package, then plugin stop working
Releases affected, V6R1M0 and M1, V7.1 and V7.2 (with different ptfs)
Release 610 : MF58587
Release 611 : MF58588
Release 710 : MF58589
Release 720 : MF58590

There is a PTF to resolve plugin stop working
* RECOMMENDATION: Apply LIC PTF MF59537 for i 6.1 *

* Apply LIC PTF MF59538 for i 6.1.1 *

For different language

======================================================================
(optional 1 - Support EN/FR/DE/IT)

1.If your system is running on another language than english, follow the steps below

# cd /usr/local/nagios/libexec/check_as400/Lang Source

2.Then copy the java class file of your language (EX:substitute french with your language)
# cp check_as400_lang_french.java ../check_as400_lang.java

3.Then compile it
# javac check_as400_lang.java

(optional 2 - Change Nagios user profile to EN)
The NAGIOS user profile has INLPGM parameter set to a CLP (MAINGBCL)
This is the MAINGBCL:
/*********************************************************************/
/* SERVER PROFILE FOR NAGIOS !!!!!!!!! */
/*********************************************************************/
PGM
CHGSYSLIBL LIB(QSYS2924)
RCLRSC
ENDPGM

This CLP change the language in English.

======================================================================

Troubleshooting

======================================================================

Use -D (debug) option,

.For example

check_as400 -D -H x.x.x.x -v DISK > debug.log

======================================================================

Change log

Excellent work! Could you upload your code to github to be able to fork it and to extend it?

I noticed that, on our system the plugin always hung during the logoff phase. after some investigation we detected that the language was changed to italian after a user logoff (the nagios user had an english profile). We solved it by adding a clean timeout. based on version 1.2.8:

~# diff checkas400/check_as400.java checkas400-original/
1521,1540d1520
< /* RPIOLA 20140407 BEGIN: introcucing a timeout for the logoff screen */
< final int finalExitStatus=exitStatus;
< Thread timeoutthread=new Thread()
< {
< public void run()
< {
< try
< {
< Thread.sleep(30000);
< }
< catch(Exception e)
< {
< }
< if(ARGS.DEBUG) System.out.println(" TIMEOUT ON LOGOFF: terminating connection...");
< close();
< System.exit(finalExitStatus);
< }
< };
< timeoutthread.start();
< /* RPIOLA 20140407 END: introcucing a timeout for the logoff screen */

Hello Roberto,

In wich part of code that your block should be in? I'm having the same problem.

Thank you.

To Roberto Piola:
TIMEOUT ON LOGOFF: terminating connection is good idea.

root cause :

When you turn on debugging

waiting for screen...
waiting for token System . . . . . (or xxxx) ...

* Nagios user need to use IBM default sign-on display file
*Or change nagiso user to other subsystem description to use system default display file(QSYS/QDSIGNON)
*Or change source code to meet your environment display file setting.

Also note:
if not English, you need recompile your LANG
(1).copy Lang Source/check_as400_langxxx to ../check_as400_lang.java
(2).Re compile. javac check_as400_lang.java

ps: help to definitions for the Italian language file is welcome.

Hello,
Great work, all is ok except i have a parsing error only with -CJS parameter. Would you have an idea?

Thanks

To Bryan DENISE:
Use -D (debug) option, redirect the output to a file and send it to me!
For example
check_as400 -D -H x.x.x.x -v DISK > debug.log

Hi,
Could you please help me translate this plugin to Swedish?
It’s not possible for us to change to English due to lots of Swedish users.

Best Regards
