Caught Exception in main process: Type Error: Cannot read property 'settings' of undefined

The error log says:

Elasticsearch Exporter - Version 1.4.0
Reading source statistics from ElasticSearch

Caught exception in Main process: TypeError: Cannot read property 'settings' of undefined

Is this error occured because of Source DB Size. Is the size too large?

Thank you.

What are you command line arguments? What version of ES are running this on?

The size of source DB shouldn't make a difference, it rather seems that a source index didn't respond with a mapping. I assume this error is consistent?

Can you tell me what response you get when you run a _mapping call?

[BlackRabbitt]

sudo node exporter.js -a 10.0.x.x -p 9200 -i A_3025 -b localhost -p 9200 -j A_3025
is the command line argument I used. And I am using ES version 1.3.2.

The command worked well with another local cluster, But when I tried it with the production cluster I got such issue.

Response is positive from _mapping call. And I am sure, the mapping is correct too.

[mallocator]

Not sure what the error here is, but ES responds without a mapping.
Maybe try with a lower case index name?

i had same exception .
eexport -a localhost -i heluo-weinxin-zhengwu -b 192.168.10.71 ,index name is lowercase.
is because of complex setting?
the index's setting

Does your ES cluster accept the setting if you set it manually? Are there any more details in the ElasticSearch log?

[thm1118]

i try again, it work now .:)

[mallocator]

Without any changes? That's weird.

[josegonzalez]

I can replicate this by using an alias for the sourceIndex. When switching to the actual index name, all works fine.

[mallocator]

Good to know, thanks @josegonzalez
I'll be sure to consider that with the 2.0 implementation.

[josegonzalez]

Yeah, my current hack to is to find the index being aliased - fun with bash! - and then retrieve that one.

[mallocator]

Yes, a little late, but I've moved on to other projects. Unfortunately, I can't point you to any other repo that forked and continued the work here, so you'll have to look for another solution, although I believe AI will soon make all of these little tools obsolete.

Most functionality was broken when ES moved to v6, and I don't even know what version we're on today, so it's no surprise it's broken. If there's huge demand I may come back to this as I was working on a more generic implementation with drivers for different DBs, a web GUI, and other little improvements. For now, consider this project abandoned 😢. One person can only do so much.
