PowerStore: Slik bruker du PowerStore Rest API

Replikasjonstilstand:
curl -H "Godta: 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

Systemvarsel:

Overvåkingshendelser:
curl -H "Godta: 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

Utgangen kan være enorm og trenger filter. For eksempel for å se hendelser relatert til brukeradministrator. 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

Vanlige feil med Rest API:

Legg til "-v" i curl-kommandoen for å vise feilen. 

Eksempel 1: feil legitimasjon.

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

* Forespørsel fullstendig sendt av

< HTTP/1.1 401 Uautorisert
< WWW-Authenticate: SSOCustom realm = "Cyclone Realm"
< Innholdstype: søknad / json
< innhold-lengde: 0

Eksempel 2: httpd kjører ikke.

curl -v -H "Godta: application/json" -u "admin:********" -k https://xx.xx.xx.xx/api/rest/hardware?select=id,name,type,lifecycle_state?type=eq.Node
