Question on Usage

[bmbermn]

Hello,

I have a GoDaddy Dedicated server and have installed the x-ray agent, credentials, and the aws-xray plugin you provided but nothing appears to be sent to AWS.

bash-4.1# xray -o -n us-west-2
2020-06-18T07:27:09-07:00 [Info] Initializing AWS X-Ray daemon 3.2.0

2020-06-18T07:27:09-07:00 [Info] Starting proxy http server on 127.0.0.1:2000

This looks to be correct to me. Can you give me any idea on a way to test this or see if it is working as expected? The Wordpress site is getting clicks and the plugin is enabled.

If everything is working, you should see these logs in the X-Ray daemon logs - https://docs.aws.amazon.com/xray/latest/devguide/xray-daemon.html#xray-daemon-logging

Particularly something similar to -

2016-11-24T06:07:08Z [Info] Successfully sent batch of 1 segments (0.123 seconds)
2016-11-24T06:07:09Z [Info] Successfully sent batch of 1 segments (0.006 seconds)

Do confirm if you have installed xhprof PHP extension, you should see it in PHP info.

Hello,

Yes I can.
[root@s192-169-216-152 ~]# php -m | grep xhprof xhprof
I can also confirm the following in the log:
`[root@s192-169-216-152 ~]# /usr/bin/xray -n us-west-2 &

Looks like you need to configure the X-Ray daemon based on that, as it looks like you don't have an IAM instance profile.

Hi, its actually configured, I just forgot to use -o on launch that time (since its not inside AWS).

Hello, Is there any update on this? I am still unable to see any info coming from non AWS servers via Xray plugin. Thanks for your help!

[adambiggs]

I'm having the same problem. I have installed and activated the aws-xray plugin, and have a sidecar container running the official amazon/aws-xray-daemon Docker image, and I confirmed that the xhprof extension is installed.

But I never get any X-Ray log messages after the initial daemon startup sequence.

Any ideas? Do you have usage instructions documented somewhere?

[orrinsheppard]

@adambiggs Did you ever figure this out? I am having the same issue. Plugin/xhprof extension installed, X-Ray agent running w/ IAM permissions, but no X-Ray logs messages after the start-up.

I have added debug logs and determined that the !function_exists(namespace . '\bootstrap' ) conditional is returning, which apparently means X-Ray is disabled? Wordpress shows the plugin as active, though. Any help here would be greatly appreciated.
