Resolving OpenTelemetry Errors in Actix-Server

```thread 'actix-server worker 2' panicked at 'called `Option::unwrap()` on a `None` value', src/service/traces/otlp_http.rs:237:73 thread 'actix-server worker 3' panicked at 'called `Option::unwrap()` on a `None` value', src/service/traces/otlp_http.rs:237:73 thread 'actix-server worker 0' panicked at 'called `Option::unwrap()` on a `None` value', src/service/traces/otlp_http.rs:237:73 thread 'actix-server worker 1' panicked at 'called `Option::unwrap()` on a `None` value', src/service/traces/otlp_http.rs:237:73 thread 'actix-server worker 2' panicked at 'called `Option::unwrap()` on a `None` value', src/service/traces/otlp_http.rs:237:73 thread 'actix-server worker 3' panicked at 'called `Option::unwrap()` on a `None` value', src/service/traces/otlp_http.rs:237:73```

Ashish

its failing because no value is set for start_time_unix_nano

Riccardo

ok, I'm check the data, I want to user OpenTelemetry with PHP...

Ashish

sure

Ashish

Ashish

check this for data model

Riccardo

Ashish if I try with first data example, I got: ```{"code":400,"message":"Invalid json: the structure must be {\"resourceSpans\":[]}"}```

Riccardo

On the server now: ```[2023-10-06T12:37:34Z INFO actix_web::middleware::logger] 172.16.2.3 "POST /api/default/traces HTTP/1.1" 400 83 "447" "-" "curl/7.88.1" 0.000484```

Riccardo

So it's better :slightly_smiling_face:

Riccardo

With PHP if I set `OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf` I don't receive data... I don't understand what I'm doing wrong

Riccardo

```env OTEL_PHP_AUTOLOAD_ENABLED=true \ OTEL_METRICS_EXPORTER=none \ OTEL_LOGS_EXPORTER=none \ OTEL_SERVICE_NAME=smb \ OTEL_TRACES_EXPORTER=otlp \ OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf \ OTEL_EXPORTER_OTLP_HEADERS="Authorization=Basic XXXX" \ OTEL_EXPORTER_OTLP_ENDPOINT= \ php -S localhost:8088```

Riccardo

I'm trying with this example:

Ashish

```OTEL_EXPORTER_OTLP_ENDPOINT = localhost:5081```

Ashish

please note this is for non-HA deployemnet

Riccardo

Ok, actually I've remote host behind haproxy and I forward only port 5080

Riccardo

```docker run -d --name "openobserve" --volumes-from openobserve-data -e ZO_DATA_DIR="/data" -p 5080:5080 \ -e ZO_ROOT_USER_PASSWORD="XXX" \ public.ecr.aws/zinclabs/openobserve:latest```

Riccardo

So, I've to expose also port 5081?

Ashish

yes

Riccardo

Ok, I'm trying...

Riccardo

but I need to set `OTEL_EXPORTER_OTLP_PROTOCOL=grpc` to `grpc` correct?

Ashish

yes..if you want to use grpc with proto

Ashish

since you are gone forward to 5081 it has to be grpc

Riccardo

ok...

Riccardo

I've to check my configuration, because I didn't see any traces...
