@ayh20 . Thank you so much Andy for your inputs. In Solace, I don't see any option to turn on DEBUG mode. I tried using MQTT.fx tool that is mentioned. Able to see Client ID in MQTT Sessions. But in the MQTT.fx console, "session present: false". Could you please let me know if I am missing something here.

@ayh20

@hari-kasetty i was thinking of DEBUG for the FLOGO_lOG_LEVEL ... what messages does the trigger generate when it tries to connect.
If you can't get MQTT.fx to connect then i suspect that the problem is at the Solace end..... you need a Solace expert i guess

hari-kasetty

@hari-kasetty

Thank you for quick reply. It is showing below log in Flogo when I used MQTT Topic Subscriber which does not have errors.

Andy Hampshire

@ayh20

Turn on DEBUG and what other messages do you get ?
Do you know Solace provides a fully compliant version of MQTT ? If MQTT.fx doesn't work either then i don't think Flogo is your problem

@hari-kasetty a while back we had some issues reading from mqtt broker using paho.mqtt.golang library (which flogo trigger uses to connect to mqtt) version v1.2.0 . However we were able to read using v1.1.1 . I would suggest creating a sample Go program and test out which version is able to connect and read .

hari-kasetty

@hari-kasetty

Thank you Andy and Samip for sharing valuable inputs. I will look into it and will see if I get any connection to Solace using MQTT. Thanks Again !!!

@alexandrev

do we have something like an if;then;else function to use inside the mappings?

Mark Mussett

@mmussett

@alexandrev i use a graphite/grafana container. Works a treat for time series data

Alexandre Vazquez

@alexandrev

thanks @mmussett I'll take a look at another option instead of using Prometheus!

Mark Mussett

@mmussett

@mbestazza RPI is still the best device to show off flogo on

Hi All,
Hope you are doing good!
I've been trying to send a kafka message via "Publish Kafka message" activity. But it errors out saying the below

"Kafkapub failed to create a SyncProducer. Check any TLS or SASL parameters carefully. Reason given: [kafka: client has run out of available brokers to talk to (Is your cluster reachable?)]"

NOTE: zookeeper(3.4.14) & kafka(2.12-2.2.0) broker are running in localhost in its default ports. Topic is also created. Basic producer-consumer test works with kafka-console-producer.bat & kafka-console-consumer.bat
Any pointers? Thanks!

@jvanderl

@mbestazza I made some flogo device profiles for espressif32 as well. See ESP32 under https://github.com/jvanderl/flogo-components/tree/master/device/profile but Flogo device is not in a very useful development stage yet. Feel free to reach out if you need any help.

There seems to be some compatibility issues while using sarama cluster(Shopify/sarama#941)

Hi This is Siva.. I am new to Flogo.. can you tell me how to provide Config parameters in UI? For example in the rest trigger if i want to provide port as a config param..

Matt Ellis

@mellistibco

If you want to use an env car just type $env.NAME_OF_VAR

sivagtibco

@sivagtibco

Thanks Matt where can i define these vars in ui?

Matt Ellis

@mellistibco

You don’t define env vars in the ui. You will just need to set them at runtime

sivagtibco

@sivagtibco

ok if i multiple then while running the app can i set all of those vars with spaces something like ./myapp $env.Name=Siva $env.ID=1 etc?

sivagtibco

@sivagtibco

i set the env variable like FLOGO_APP_PROPS_OVERRIDE=C:\Users\sganise\Downloads\props.json and i had given variables in the file

but some how it is not taking it from the file

i added "properties": [
{
"name": "port",
"type": "string",
"value": "8002"
}
],

in the app

and my props.json having { "port": 8003 }

C:\Users\sganise\Downloads>FLOGO_APP_PROPS_OVERRIDE=C:\Users\sganise\Downloads\props.json healthcheck-gv_windows_amd64.exe
'FLOGO_APP_PROPS_OVERRIDE' is not recognized as an internal or external command,
operable program or batch file

or if i run without giving the above env prop my app is still taking default value

Leon Stigter

@retgits

If you’re running on windows you’ll need to use either the set command first to create an environment variable or add them using the control panel (the way you’re trying it now is how it works in Linux / macOS)

sivagtibco

@sivagtibco

Hi Leon I did that before I test

But the variable which I specified is not picking from the file

Leon Stigter

@retgits

Also, can you just run SET and check the variable you created is present?

sivagtibco

@sivagtibco

I did set also before I run it

Leon Stigter

@retgits

No, I mean when you run “SET” (don’t add anything) it shows all environment variables your terminal on windows knows about

Can you check if you run that, that the variable you created exists?

sivagtibco

@sivagtibco

YES

sorry for caps

ComSpec=C:\WINDOWS\system32\cmd.exe
DriverData=C:\Windows\System32\Drivers\DriverData
FLOGO_APP_PROPS_OVERRIDE=C:\Users\sganise\Downloads\props.json

Leon Stigter

@retgits

Hmm I don’t have my windows machine here to debug that issue 🤔 your environment is set properly

sivagtibco

@sivagtibco

do we have any trigger available for ems queue receiver?

Leon Stigter

@retgits

Yeah, I think that @mmussett created one... you might want to check in his GitHub repos

sivagtibco

@sivagtibco

ok.. i checked it here https://tibcosoftware.github.io/flogo/showcases/ but do see only for send .. but nothing for receiver..

https://github.com/mmussett/ems i will check this..

Alexandre Vazquez

@alexandrev

@sivagtibco if you have Powershell

you can try this

$Env:FLOGO_APP_PROPS_OVERRIDE=<PATH>

it works for me

sivagtibco

@sivagtibco

ok thank you let me try that
