Request yml confirmation of flex bundled with agent about nri-flex

[Kav91]

@dokyun-kim without seeing the verbose log its hard to exactly tell what is going wrong.

I am assuming its because your lookup file is not in the location the Flex binary is anymore, and its not reading the file relative to the path.

I would update lookup_file: to use the full path to rule this out first.

eg.

lookup_file: /etc/newrelic-infra/integrations.d/testLookup.json

cc/ @ardias this is another typical use case where suggesting to debug by running the single config and supplying the output would be useful but we can't suggest that anymore.
This makes it extremely difficult for customers to debug when moving files around and especially when dealing with anything to do with paths in general.

@dokyun-kim How are you running the example? Are you executing Flex directly (is ./nri-flex -config_path) or are you running the newrelic agent?
The format of the configuration file for Flex has not changed you can still use the examples like before.

If you are using Flex only, for example testing your configurations, see here: https://github.com/newrelic/nri-flex/blob/master/docs/development.md

If you want to use Flex with the agent so you see the data in NR, see here: https://github.com/newrelic/nri-flex/blob/master/docs/basic-tutorial.md

As @Kav91 has said, don't use relative paths, it is better to always use absolute paths when referring to files

@Kav91 We'll try to mitigate these issues in the next phase we are planning for Flex, making the agent have better support for Flex configs

I'm using flex through the newrelic latest agent.

And modified lookup_file as follows.
lookup_file: /etc/newrelic-infra/integrations.d/testLookup.json

The following error message was output from the newrelic-infra.log file.

time="2020-03-06T01:01:57Z" level=warning msg="can't load integrations file. This may happen if you are editing a file and saving intermediate changes" component=integrations.Manager error="yaml: line 10: did not find expected '-' indicator" event="\"/etc/newrelic-infra/integrations.d/portTestWithLookup.yml\": DELETE" file_name=/etc/newrelic-infra/integrations.d/portTestWithLookup.yml function=handleFileEvent

In my opinion, nri-flex used to support the following syntax, but it does not seem to support Flex bundled with the newrelic agent.

    commands:
     - dial: ${lf:addr}

Thank you!

@dokyun-kim
The following integration config yml file(new fomat) should allow you continue to run the Flex integration yml files created previously without any modification required.
# more /etc/newrelic-infra/integrations.d/myflex.yml

integrations:
   - name: nri-flex
     exec:
       - /var/db/newrelic-infra/newrelic-integrations/bin/nri-flex
       - --config_dir=/var/db/newrelic-infra/custom-integrations/flexConfigs/
     interval: 60s
     working_dir: /var/db/newrelic-infra/custom-integrations/flexConfigs/

the working_dir should point to where the lookup files are located.
the config_dir should point to where the Flex integration yml files created in previous version.

Hello Haihong

I've confirmed that flex works fine with the method you gave me.

Thank you

@haihongren

As you told me, I used the same method on Windows, but I get an error. Can you please tell me what went wrong?

C:\Program Files\New Relic\newrelic-infra\integrations.d\myflex.yml

integrations:
   - name: nri-flex
     exec:
       - "C:\Program Files\New Relic\newrelic-infra\custom-integrations\nri-flex.exe"
       - --config_path="C:\Program Files\New Relic\newrelic-infra\custom-integrations\portTestWithLookup.yml"
     interval: 30s

newrelic-infra.log error log

Thank you

Hi @dokyun-kim
from the error message it seems it is unable to find the file C:\Program Files\New Relic\newrelic-infra\custom-integrations\portTestWithLookup.yml

Can you try copying that file to a folder with a simple name, like for example c:\flex\portTestWithLookup.yml ? It could be a problem with spaces in the name of the folder
