Hi,
I'm trying to collect some metrics from Google Compute APIs but cannot figure out how to use the plugin.
I got error code 400, maybe my filters are wrong...

## How to reproduce

- **Environment**:
result of `uname -a ; cat /etc/redhat-release /etc/debian_version`:

```
Linux server.domain 4.18.0-477.21.1.el8_8.x86_64 #1 SMP Thu Jul 20 08:38:27 EDT 2023 x86_64 x86_64 x86_64 GNU/Linux
Red Hat Enterprise Linux release 8.8 (Ootpa)
```

- **Version of the plugin**: `20240311-143354.el8`
- **Information about the monitored resource**: Google API
- **Command line**:

```
./centreon_gcp_management_stackdriver_api.pl \
  --plugin=cloud::google::gcp::management::stackdriver::plugin \
  --mode=get-metrics \
  --key-file=key.json \
  --dimension-name=metrics.labels.instance_name \
  --dimension-operator=equals \
  --dimension-value=NAME \
  --metric=instance/cpu/utilization \
  --api=compute.googleapis.com \
  --warning-metric=90 \
  --critical-metric=95 \
  --verbose \
  --proxyurl=http://proxy.domain:9090 \
  --http-backend=curl \
  --insecure \
  --debug
```

 

## Expected result

Some metrics...

## Actual result

 

```

Thanks in advance for any help,

 

hello

just to be sure, did you run the command as displayed above ? (i’m guessing you replaced NAME with a real instance name.)

was there some single quote for each values as here in the documentation  : https://docs.centreon.com/pp/integrations/plugin-packs/procedures/cloud-gcp-management-stackdriver/#how-to-test-the-plugin-and-what-are-the-main-options-for

(there may be some automatic string conversion with double quoted string, and normally when using the service template from the plugin pack the single quotes are automatically used)

given the error returned by google says you should prefix with something and that something is there (prefix.) but with \” at the start and perl will automatically put double quotes on a string parameter, there may be some cause and effect here.

just an hypothesis, but if it’s not that, then I don’t know what’s happening 

 

best regards

Hi, thanks for the quick response.

 

just to be sure, did you run the command as displayed above ? (I’m guessing you replaced NAME with a real instance name.)

was there some single quote for each values as here in the documentation

 

Yes I’ve tried both single and double quotes, with or without ‘=’ operator, got same results..

--flag="argument"
--flag "argument"
--flag='argument'
--flag 'argument'


Yes, NAME was replaced with the actual instance name.

Do you think is it appropriate to fill an issue on Github?

maybe not

maybe there was a change in the GCP api, or maybe it is something else, no idea (I don’t have any gcp resources to try this plugin)

you could also try to debug the api call by calling the google api from a software like postman or insomnia, 

 

if you look at your full log it says exactly the query used : 

GET /v3/projects/prj-isp-netq0-iaas-test-001/timeSeries/?filter=metric.type+%3D+%22compute.googleapis.com%2Finstance%2Fcpu%2Futilization%22+AND+metrics.labels.instance_name+%3D+%22NAME%22&interval.endTime=2024-03-19T14%3A08%3A37.000000Z&interval.startTime=2024-03-19T13%3A58%3A37.000000Z

this translate to 

GET/v3/projects/prj-isp-netq0-iaas-test-001/timeSeries/?filter=metric.type+=+"compute.googleapis.com/instance/cpu/utilization"+AND+metrics.labels.instance_name+=+"NAME"&interval.endTime=2024-03-19T14:08:37.000000Z&interval.startTime=2024-03-19T13:58:37.000000Z

 

edit:

and as I was typing this i see what you may have done wrong, the error from google is not happy with the “lefthand” part of the filters and look at the example I linked above

and what you passed in the argument

i’m guessing the “s” in metric may not be ok, but i can’t test it

 

if the additionnal s in metrics is not the issue, it may come from the quotation marks, that you can test buy using insomnia or postman and passing your api key on that “GET” url

That was a typo and of course as I corrected it, it works now!
Thank you very much!
