gcp cli error =(gcloud.logging.write) unrecognized arguments

Question

I am writing logs in gcp logs using below command:

gcloud logging write my-test-log '{ "ServiceName": "$Service1", "SubsystemName": "$subsystem1") --payload-type=json

it is giving below error:

(gcloud.logging.write) unrecognized arguments.

Please suggest

Answer 1

You are receiving that error because you have some syntax errors.

As LundinCast said, the correct command should be:

gcloud logging write my-test-log '{ "ServiceName": "$Service1", "SubsystemName": "$subsystem1"}' --payload-type=json

You only will receive the following output:

Created log entry.

Please check the following documentation for further information: gcloud logging write

And you could verify if it works listing your project's logs:

gcloud logging logs list 

NAME
projects/<<PROJECT-ID>>/logs/my-test-log

or reading the log entry:

gcloud logging read my-test-log

Edit 1

I found the problem in my original answer. To get the value of a variable in a json format it is necessary to add "'" so the command should be something like:

gcloud logging write --payload-type=json my-test-log '{ "message": "'"$variable"'" , "weather": "partly cloudy"}'

Where the content of $variable is my-variable-content

insertId: 1y7abcdefghijk
jsonPayload:
  message: my-variable-content
  weather: partly cloudy
logName: projects/<<PROJECT-ID>>/logs/my-test-log
receiveTimestamp: '2020-12-04T14:03:45.850928566Z'
