AS/400 Monitoring solutions

[turki]

check, please, that you use the last version of the Zabbix agent emulator (0.7.9 at the moment).
I provided an announce about this problem and an update some time ago (see link here).
If the problem still persist with this version, contact me directly by e-mail, please.

Yes that was the problem, I downloaded new version almost year ago, but didn't applied ... brain is "funny felow" when you assume something.

Kos, thank you and sorry to spend your time for something what was my mistake ...

at the end everything works well even with newest PTF's.

best regards,
turki

Version 0.6.3 was published here.

Change list:

• some additional debugging info added;
• initialization improved. For example, if the JSON library could not be found, the program will stop gracefully immediately (instead of some strange semi-live state);
• negative values of CPU Usage should be avoided now.

Hi Kos, first of all, thank you for all your work. I´m looking for the template that you previously shared, I would be really grateful if you can provide me a link with the template. I´m trying to implement with the version 7.7, I have some difficulties to understand the new version with the directory Source and Go

Hi Julian,
thank you for a feedback.
The current version is 0.7.9, it's available by the link published here. I highly recommend to use this version, as it has fixes of bugs found earlier, as well as some additional features (see the section "History" in documentation).

All published versions have the same structure: it's a ZIP-archive containing a compiled version of Agent (jar-file), a detailed documentation (in PDF), example of the config file and another ZIP-archive with the sources. The sources archive is interested only if you like to explore internals of this agent or if you like to recompile it by yourself. The GO.BAT file here is the script used by me to recompile and build (including all needed resources) the resulting JAR-file from scratch, and then to start it if it was built successfully. If you don't want to recompile, the sources.zip archive is not necessary.

Unfortunately, there is no officially supported template for that operation system. Several year ago I published an example of a template (it is still available here, you can look the branch for the v5.0, as it has not been modified since then); however, keep in mind that it's not some "recommended" settings or some "best practices", but only an example to demonstrate how this agent could be used.

ello Kos.
I'm trying to locate a couple of files that I can't find to have everything I need to install the zabbix agent that you have developed to obtain information from an iSeries as/400 system. I can't found the files jt400.jar and json-simple-1.1.1.jar.
Could you please help me with this search?
thank you in advance for your time and your contribution to the world zabbix

[Kos]

I can't found the files jt400.jar and json-simple-1.1.1.jar.
Could you please help me with this search?

The links for both these dependencies (as well as detailed instructions how to run this agent) are in documentation:

• json-simple-1.1.1.jar (link);
• jt400.jar (link), now moved here (the current download page is here)

Hi bvollmer,

I don't have experience with this error, but at the end of the log notice "system.uname" as a problem.

I suggest to check that your name resolving (DNS) on your IBM i system is working well.

Check that your system has correct TCPIP name configuration in CHGTCPDMN command.
(just enter command and press F4 to see what is configured for Hostname, Domain name and Domain name server(s))

Also try to ping by using symbolic (textual, not IP) names of your server and zabbix server not just to check if they are reachable but also to be sure that name resolving is functional.

So check hosts you enter under following parameters inside your /home/ZABBIX/agentd/zabbix_agentd.conf config file:

Server = zabbix.domain.local
ServerActive = zabbix.domain.local, localhost
Hostname = MYIBMI

So in this example check that you can resolve:
PING RMTSYS('zabbix.domain.local')
PING RMTSYS('MYIBMI')



best regards,
turki

Hi bvollmer ,
from the provided log file we can see the following:

• you are starting this agent on the IBMi system (architecture is: OS/400 ppc64-64-Bit);
• the agent got the error trying to ask the "system.uname" metric (it asks this metric at the end of its initialization to write this information into the log, too);
• the error is "A remote host refused an attempted connect operation".

Are you trying to monitor another IBMi host from this IBMi system? If not, are you using some credentials in your configuration file (the "User", "as400ServerHost" and "as400Password" parameters)? All these parameters are not required for the local IBMi system monitoring; if they are specified, they could be commented out. And just opposite: for the remote monitoring all there parameters must be specified (as described in the documentation).

Thanks.

[jsolman]

If you check out page 9 onwards, these issues have already been covered.
CPF34C4 is an OS400 error, so nothing the Zabbix Agent Emulator is generating, I've logged a call with IBM on this one myself, as I'm new to this, so seeing if there is an OS parameter to help etc.
CPF3C53 means the job has been removed during the list processing (was there at the start, but gone now).

[obermotz]

Hello, just started using the IBM i Zabbix agent and so far so good - thanks Kos for implementing such a useful piece of software. Also after dabbling around a bit I realized that the AS400 agent does not support the system.run metrics and that made mi a little sad Checked the sources and I can see that you already did some testing but commented out the relevant part due to bugs (I presume). Also I would prefer to run a shell script instead of a "classic" AS400 command as you can also call native commands/programs with the SYSTEM PASE command (whenever I am allowed to, I install the OSS environment for IBM i to have the proper GNU tools on my LPARs). Any chance for you to look into this or bugfix the preliminary system.run function (I would gladly do it but unfortunately I can't develop in Java)?

[ChrisQCK]

Hi Kos,

ChrisQCK,
the 'system.uname' metric must work for the agent be usable.
It uses this metric at the very beginning of its work (during a startup and initialization) to output some general information about the system to the log file.
Obviously, the error is occurring just during this time in your case.
Unfortunately, the only useful information we have now is the following:

com.ibm.as400.access.ErrorCompletingRequestException: An error occurred on the system.

According to documentation for API, the ErrorCompletingRequestException can occur during the SystemStatus.getSystemName() call:

If an error occurs before the request is completed.

Unfortunately, that's all that I can tell - there is no more detailed hints about reasons
The rest is just guesses.

Did the agent work on this system successfully before? If yes - were any changes on this system or agent configuration?
Is the user for this agent exist and not disabled/locked/etc.?

We had similar error after going to V7R6 and started playing with MFA. Turned out to be Java tool box (JT Open) - Downloaded lates build and implemented - Solved problem with "system.uname".

[ChrisQCK]

Kos We identified the root cause of the problem~!!! It was due to the storage space assigned to the profile was insufficient to accommodate the log file size. After we increased that and also fix permission so that the log file can grow without being limited by the storage size limitation, the agent was able to run as normal. hahahaha~!!! I will note this down in the KB that we are building so that these would be the things that we need to check if we come across similar issue on the production servers later on.

[Kos]

ChrisQCK, thank you for sharing the cause of this problem and the solution!

[ChrisQCK]

Kos Sorry I am just checking... are any updates on this agent ? I understand you are doing this based on your free time and motivation so no worries if no updates.

just wanted to share that I tested also another method which is via ODBC. So far I am able to query some metrics. However, when it comes to QSYSOPR message queue, it failed to successfully get the information. I'm not sure if anyone here has any knowledge on this issue. It seems message queue is the limitation for monitoring in Zabbix ? hahaha

[Kos]

Unfortunately, up to now the latest version still is 0.7.9
I hoped to perform some modifications this year; but...
Maybe, I'll return to this task next year (2026).

I reproduced your problem and kind of fixed it but im not really happy with the results.

I gues on your first run of the agentd the agentd complained about a missing user "zabbix".

Did you create a new userprofile "ZABBIX" via CRTUSRPRF? If so, delete it. I think the agent tries to check for the existence of a userprofile "zabbix" via id -un or some API and then tries to "su" to it. Since we dont ahve a "su" in PASE this fails hard. Giving some obscure errors like yours.

Well, the bad news here is: After removing the user "zabbix" from the system the agentd only would run when the invoking userprofile has the attribute
GRPPRF(QPGMR) - wich of course raises some security questions.

I don't quite understand what is happening here. Even after adding all special permissions from QPGMR to my zabbix-agentd user, the agentd would only run when the profile has it GRPPRF as QPGMR, similar to how you need proper access to Descargar Minecraft before running the installer.

So, the quick fix for your problem shoudl be:

1. Remove user "zabbix" from the system
2. Addd GRPPRF(QPGMR) to the userprofile which invokes the agentd
3. Re login
4. ./zabbix_agentd should be working

I try to get a hand on that QPGMR GRPPRF thing.

Simply saving the MIB file on your Zabbix server won’t be enough. The MIB just maps OIDs; the AS/400 must expose the specific data via SNMP, and you need to configure Zabbix items to query the correct OIDs. For detailed monitoring like active processes and job queue statistics, SNMP is often limited. A more reliable approach is to use scripts or APIs on the AS/400 that extract the needed data and send it to Zabbix, or run commands via SSH/Telnet and parse the results. This method gives you full control over the metrics you want to monitor.
