Dell PowerStore Rest API does'nt have capacity check

Hi @Wisonic ,

The hardware mode of the plugin should give you information about the memory (`dimm`), according to the `--help`:

/usr/lib/centreon/plugins/centreon_dell_powerstore_restapi.pl     --plugin=storage::dell::powerstore::restapi::plugin --mode hardware --help
[...]
    --component
            Which component to check (Default: '.*'). Can be: 'appliance',
            'battery', 'dimm', 'disk', 'enclosure', 'fan', 'node',
            'iomodule', 'psu', 'sfp'.
[...]

Can you try it and display the result here?

Hi @omercier,

thank you for your answer, unfortunately the dimm option only displays the count and not the usage

/usr/lib/centreon/plugins/centreon_dell_powerstore_restapi.pl --plugin=storage::dell::powerstore::restapi::plugin --mode=hardware --hostname='XX.XX.XX.XX' --port='XXX' --proto='https' --api-username='XXX' --api-password='XXXX' --timeout=30 --insecure --component=dimm

OK: All 2 components are ok [2/2 dimm]. | 'hardware.dimm.count'=2;;;;

We don’t have that information (memory usage). If you have the information, please provide the curl example (with the json output).

Hi,
I found the curl example :
 

curl -k -s -u 'XXXX:XXXX' -X POST "https://XXXX/api/rest/metrics/generate" -H  "accept: application/json" -H  "Content-Type: application/json" -d "{  \"entity\": \"space_metrics_by_appliance\",  \"entity_id\": \"A1\",  \"interval\": \"One_Day\"}"

(Your entity_id can be different)

(interval can be [ Twenty_Sec, Five_Mins, One_Hour, One_Day ])

Here the model :

And a part of the output :

{
    "appliance_id": "A1",
    "timestamp": "2023-01-20T00:00:00Z",
    "last_logical_provisioned": XXXXXXXXXXXXXXX,
    "last_logical_used": XXXXXXXXXXXXXXX,
    "last_physical_total": XXXXXXXXXXXXXXX,

    "max_thin_savings": XXXXXXXXXXXXXXX,
    "last_shared_logical_used": XXXXXXXXXXXXXXX,
    "max_shared_logical_used": XXXXXXXXXXXXXXX,
    "last_logical_used_volume": XXXXXXXXXXXXXXX,
    "last_logical_used_file_system": XXXXXXXXXXXXXXX,
    "last_logical_used_vvol": XXXXXXXXXXXXXXX,
    "max_logical_used_volume": XXXXXXXXXXXXXXX,
    "max_logical_used_file_system": XXXXXXXXXXXXXXX,
    "max_logical_used_vvol": XXXXXXXXXXXXXXX,
    "last_shared_logical_used_volume": XXXXXXXXXXXXXXX,
    "last_shared_logical_used_file_system": XXXXXXXXXXXXXXX,
    "last_shared_logical_used_vvol": XXXXXXXXXXXXXXX,
    "max_shared_logical_used_volume": XXXXXXXXXXXXXXX,
    "max_shared_logical_used_file_system": XXXXXXXXXXXXXXX,
    "max_shared_logical_used_vvol": XXXXXXXXXXXXXXX,
    "repeat_count": XXXXXXXXXXXXXXX,
    "response_definition": "space_metrics_by_appliance_rollup",
    "entity": "space_metrics_by_appliance"
  }

for memory used, it’s “last_physical_used” and your max capacity “last_physical_total”

Wisonic, could you test with that archive ? https://github.com/centreon/centreon-plugins/archive/refs/heads/MON-16307-dell-powerstore-add-memory.zip

I’m not sure about the endpoint to get all appliances.

@Wisonic have you been able to test when Quentin sent you?

@omercier No, I have this message when I click on the link
 

It’s merged. Please use that archive: https://github.com/centreon/centreon-plugins/archive/refs/heads/develop.zip

line 106 :

my $free = $appliances->{$appliance_id}->{last_physical_total} - $appliances->{$appliance_id}->{last_physical_used};

I added lines to see the value of “appliances” :

use Data::Dumper;
print(Dumper($appliances));

Part of the value of the “appliance” variable :

the check does not just retrieve the last value which I think blocks the result

Could you provide the full result with --debug-stream option ? Sent it in a file to qgarnier@centreon.com please.
