Hi @jaronoff97 Sorry for the delayed response. unfortunately, the apache config in the file looks like below. (Please excuse me for the indentations)

Yes, I am following the instructions given in the link you shared

spec:
apacheHttpd:
configPath: /app/apache/sites/default/conf
image: openshift-docker.artifactory.techopscloud.com/apache-httpd:1.0.3 (custom repo url)

  • name: ApacheModuleotelSpanExporter
    value: otlp
  • name: ApacheModuleotelExporterEndpoint
    value: "http://otel-signalfx-collector.otel-signalfx.svc.cluster. local:4318"
  • name: ApacheModuleServiceName
    value: infra-gw
  • name: ApacheModuleServiceNamespace
    value: apache-dev
    name: ApacheModuleServiceInstanceId
    value: ${APACHE_SERVICE_INSTANCE_ID}
    resourceRequirements:
    limits:
    cpu: 500m
    memory: 128Mi
    requests:
    cpu: 1m
    memory: 128Mi

Apache version is 2.4 (RHEL) on Openshift cluster.

with Apache image version 1.0.4 I see a different error that I shared earlier.
with Apache image version 1.0.3 the apache pod goes into crashloopbackoff error.

With the 1.0.3 image after adding the annotations to the apache deployment, I see both the init containers otel-agent-source-container-clone & otel-agent-attach-apache but the pod immediately goes in crashloopbackoff.

@jaronoff97 I suspect issue with the path in include command, Please let me know your thoughts.

in the below init container the path in the include command, looks incorrect

current path :

'Include /app/apache/sites/default/conf/opentemetry_agent.conf >> /opt/opentelemetry-
webserver/source-conf/httpd.conf

should be :

'Include /opt/opentelemetry-webserver/source-conf/opentemetry_agent.conf >> /app/apache/sites/default/conf/httpd.conf

otel-agent-attach-apache:

Command:
/bin/sh
-C
Args:
cp -r /opt/opentelemetry/* /opt/opentelemetry-webserver/agent && export agentLogDir=$(echo "/opt/opentelemetry-
webserver/agent/logs" | sed 's,/\V,g') && cat /opt/opentelemetry-
webserver/agent/conf/appdynamics_sdk_log4cxx.xml.template | sed 's/agent_log_dir/'${agentLogDir)'/g' >
/opt/opentelemetry-webserver/agent/conf/appdynamics_sdk_log4cxx.xml &&echo "$OTEL_APACHE_AGENT_CONF" >
/opt/opentelemetry-webserver/source-conf/opentemetry_agent.conf && sed -i 's/ << SID-
PLACEHOLDER>>/${APACHE_SERVICE_INSTANCE_ID}'/g' /opt/opentelemetry-webserver/source-conf/opentemetry_agent.conf
&& echo 'Include /app/apache/sites/default/conf/opentemetry_agent.conf >> /opt/opentelemetry-
webserver/source-conf/httpd.conf

Could you please provide kubectl -n get pod -oyaml ? With sanitised sensitive info if there's any. It's working in my environment, I suspect an issue with privileges or alike.

Thanks for looking into it @chrlic I'll try to get the info.

@chrlic also wanted to confirm with you regarding below parameter, am I supposed to pass any specific value here? I noticed that during instrumentation it creates following environment variable - ${APACHE_SERVICE_INSTANCE_ID} which is what I am passing as value.

ApacheModuleServiceInstanceId
value: ${APACHE_SERVICE_INSTANCE_ID}

Thank you for the info provided. For whatever I've tried, I could not replicate the issue. Could we have a look at the problem in the real environment?

@chrlic would you be able to share your instrumentation yaml & instrumented pod deployment? This will help me to compare if I am missing anything.

I think I found the cause of the issue - with the apache otel instrumentation 1.0.4 image, some files have been renamed, the /opt/opentelemetry-webserver/agent/conf/appdynamics_sdk_log4cxx.xml.template file is now called /opt/opentelemetry-webserver/agent/conf/opentelemetry_sdk_log4cxx.xml.template. More on that here: open-telemetry/opentelemetry-cpp-contrib@ba0094b
This was reflected in the operator PR #3048, merged into the release 0.103.0 (see https://github.com/open-telemetry/opentelemetry-operator/releases/tag/v0.103.0)
That's the reason why older operator 0.99.0 cannot that file. So upgrading operator should resolve the issue.

There's still an open question for me, why it's failing for you with the image 1.0.3 and I'm going to investigate that.

Thanks @chrlic. Really appreciate your efforts for looking into this issue.

I recently tried something to figure out why the apache pod goes in crashloop.

I changed the configpath to etc/httpd/conf which has the default httpd.conf file, whereas the actual httpd.conf file which is used by apache is in another custom/real path, I wanted to see what modifications are done in the file.

with the config path etc/httpd/conf the pod ran successfully and, in the bash, when I ran below command

sh-4.4$ httpd -M

httpd: Syntax error on line 357 of /etc/httpd/conf/httpd.conf: Syntax error on line 8 of
/etc/httpd/conf/opentemetry_agent.conf: Cannot load /opt/opentelemetry-
webserver/agent/sdk_lib/lib/libopentelemetry_exporter_otlp_grpc.so into server: libnsl.so.1: cannot open
shared object file: No such file or directory

it appears, that libopentelemetry_exporter_otlp_grpc.so has dependency on following library libnsl.so.1.

I checked in /lib64 directory, and it had libnsl.so.2 and libnsl.so.2.0.0

Also, I verified that libopentelemetry_exporter_otlp_grpc.so is available in /opt/opentelemetry-
webserver/agent/sdk_lib/lib/

Linux version is RHEL 8.10

I think it may be throwing same error when we set the configpath to the custom/real path and therefore the pod goes in crashloop as apache server is not staring up.

I tried this with operator version 0.99 and Apache image 1.0.3. No, this is not the file naming issue.

I am yet to add the required library libnsl.so.1 and see if it works. For the versions that I am using, I guess the libnsl.so.1, which is a Linux library is a dependency for supporting Apache instrumentation.

is there a way to find out if it's the similar case with the latest version of the Operator and Apache image?

I found a somewhat similar issue regarding the missing library : https://access.redhat.com/solutions/4975641
