PowerStore: PowerStore Rest API'sini kullanma

Replication State:
curl -H "Kabul et: application/json" -u "admin:********" -X GET -k https://xx.xx.xx.xx/api/rest/replication_session?select=id,role,state,last_sync_timestamp,local_resource_id

Çıktı örnekleri:

{"id":"047e38ee-9aeb-4761-8ca5-393204fe6584","role":"Metro_Preferred","state":"OK","last_sync_timestamp":"2026-07-16T15:48:05.628263+00:00","local_resource_id":"d34bd80e-1d43-4692-ab37-e307bc92eb73"},
{"id":"26dd4105-a24f-4d82-b40b-20dcefbfe5df","role":"Kaynak","state":"OK","last_sync_timestamp":"2026-07-16T15:31:54.64127+00:00","local_resource_id":"82c40277-dee4-46de-8559-920fe5f942cc"},
{"id":"414dba20-08b1-4d5e-a521-517a3b37473a","role":"Metro_Preferred","state":"OK","last_sync_timestamp":"2026-07-16T15:51:05.525764+00:00","local_resource_id":"eb970724-cc3e-4661-8d71-bec7f44baf10"}

Sistem Uyarısı:
curl -H "Accept: application/json" -u "admin:********" -X GET -k https://xx.xx.xx.xx/api/rest/alert?select=id,event_code,severity,resource_type,generated_timestamp,state,description_l10n

Çıktı örnekleri:

{"id":"008abb47-e72d-4608-b915-b8c01328b64e","event_code":"0x01700304","severity":"Binbaşı","resource_type":"remote_system","generated_timestamp":"2026-05-11T01:51:01.280627+00:00","state":"ACTIVE","description_l10n":"Uzak sistem Ghost'tan gelen tüm veri bağlantıları kesildi."},

Denetim Olayları:
curl -H "Accept: application/json" -u "admin:********" -X GET -k https://xx.xx.xx.xx/api/rest/audit_event?select=id,type,timestamp,username,resource_type,resource_action,message_l10n,client_address

Çıktı çok büyük olabilir ve filtreye ihtiyaç duyabilir. Örneğin, admin kullanıcı ile ilgili olayları görüntülemek için. Try:
curl -H "Accept: application/json" -u "admin:********" -X GET -k https://xx.xx.xx.xx/api/rest/audit_event?select=id,type,timestamp,username,resource_type,resource_action,message_l10n,client_address?username=eq.admin

Rest API ile ilgili sık karşılaşılan hatalar:

Hatayı göstermek için curl komutunuza "-v" ekleme. 

Örnek 1: yanlış kimlik bilgisi.

curl -H "Kabul et: application/json" -u "admin:wrong_password" -k https://10.241.219.160/api/rest/hardware?select=id,name,type,lifecycle_state?type=eq.Node

* İstek tamamen gönderildi
* TLSv1.3 (IN), TLS el sıkışma, Newsession Ticket (4):
< HTTP/1.1 401 Unauthorized
< WWW-Authenticate: SSOCustom realm="Cyclone Realm"
< content-type: application/json
< content-length: 0

Örnek 2: httpd çalışmıyor.

curl: (28) 31939 ms'den sonra xx.xx.xx.xx bağlantı noktası 443'e bağlanılamadı: Sunucuya bağlanılamadı

Örnek 3: içerik türü olmadan yanlış sözdizimi.

curl -v -H "Accept: application/json" -u "admin:********" -X POST -k https://xx.xx.xx.xx/api/rest/metrics/generate -d '{ "entity": "performance_metrics_by_appliance", "entity_id": "A1","interval": "One_Day" }'
