Large 'From' number, Out of Range Error - Agent-Agent

[nickamenda]

We have a DMG running with IoTConnector and Agent 1.3. We configured Agent-Agent connection in our 2.x Agent. It looks like our Agent is getting some bogus from query string.... Any suggestions on how to troubleshoot this?

What is the 1.3 agent current nextSequence?

It could be a header parsing issue or an upstream agent issue. Can you check the response doc from the upstream agent. Btw the image did not load.

[nickamenda]

The nextSequence on the 1.3 agent is 20090. Does the image load for you now? That is our 2.x Agent. I have attached a snippet of the 1.3 Agent

I wonder if this is a version issue. I tested with a 2.0 agent. The 1.3 agent is ancient, around 10 years old. I need to set up a test and see if I can reproduce the issue.

[nickamenda]

Okay, let me know what you find! Thanks Will!

[MRIIOT]

Agreed 1.3 is ancient, yet I am surprised how many people and DMG, Cisco, etc use it.

[wsobel]

I'll need to look into this. The response documents haven't changed a lot since 1.3. There are extra attributes, but it should work.

[wsobel]

I'm going to see if I can reconstruct a 1.3 that matches the version you're running on Windows and try to reproduce the error.

Do you have the Device.xml and agent.cfg from the 1.3 machine (DMG Mori)?

[wsobel]

Also, please upload agent.log file with log level set to debug:

logger_config
{
    logging_level = debug
    output = file agent.log
}

[wsobel]

After reviewing the log output, I need to see the old DMG Device XML file to check if there aren't some errors that are causing this. The Events:AssetChanged:DOUBLE indicates that the original configuration had units for the asset changed event. This would be rather odd. I need to check of there are other issues that may be causing things to trip up the validation code in the new agent.

[nickamenda]

Hi Will, I do not have access to the machine right now so I cannot grab the logs. I do have access to the updated Agent if you want those logs and config files. I drew this diagram in hopes that it would help explain what we are doing. Basically, we grab the probe from the 1.3 Agent running on port 15404 and then add that to our devices.xml on the up to date Agent. When this error was occurring we had period filters on every single DataItem, which could've contributed to this. Also, I had units="SECOND" at the end of every DataItem as I thought that would apply to the period filter but I think I was completely wrong with that. We also have a relay running on the same device as the up to date Agent that will pull the sample every 5 seconds and send that data to Splunk. Let me know if you have any questions or need some additional information, I wonder if this was all caused by me just not setting everything up properly.

[wsobel]

Can you upload your devices.xml file to the issue? I think it is causing the problem.

I think adding units="SECOND" to every data item caused some weird behavior.

Originally, the machine was spewing some samples multiple times a second, which prompted this issue: #475. After agent-agent filters were implemented, we noticed issue 505.

The units are probably breaking everything. I have not tested with this configuration. I would remove the units and try again. This is not a bug in the agent since it is validating the types.
