Objective

Checking the performance behavior of the OSIS service on scality cloud. As OSIS is not configured through NGINX, only one node will be configured in vCloudDirector.

  • Tenant Flow: Query/Create/List Tenant

  • User Flow: Query/Get/Create/List User

  • Credential Flow: Query/Get/Create/List Credentials

Test Cases:

  • Base Case:

    • Simple flow → Query/Create/List Tenant, Query/Get/Create/List User, Query/Get/Create/List Credentials

  • Medium load:

    • 1 client (threads)

      • (loop count) 100 x Tenant Flow, User Flow, Credential Flow

      • (loop count) 1000 x Tenant Flow, User Flow, Credential Flow

      • (loop count) 10000 x Tenant Flow, User Flow, Credential Flow

    • 2 clients (threads)

      • (loop count) 100 x Tenant Flow, User Flow, Credential Flow

      • (loop count) 1000 x Tenant Flow, User Flow, Credential Flow

      • (loop count) 10000 x Tenant Flow, User Flow, Credential Flow

    • 4 clients (threads)

      • (loop count) 100 x Tenant Flow, User Flow, Credential Flow

      • (loop count) 1000 x Tenant Flow, User Flow, Credential Flow

      • (loop count) 10000 x Tenant Flow, User Flow, Credential Flow

  • Ramp Up test - Stress failure test

    • Tenant Flow, User Flow, Credential Flow
Clients (threads) Loop Count(number of times to execute the test per thread) Rampup time: (Ramp-Up Period tells JMeter how long to delay before starting the next user) (in seconds)

Metrics to capture:

  • Elapsed time: Measures the elapsed time from just before sending the request to just after the last chunk of the response has been received,

  • Latency: Measures the latency from just before sending the request to just after the first chunk of the response has been received,

  • Median: Number which divides the samples into two equal halves,

  • 90% Line (90th Percentile): The elapsed time below which 90% of the samples fall

  • 95% Line (95th Percentile): The elapsed time below which 95% of the samples fall

  • Throughput: Calculated as requests/unit of time. The time is calculated from the start of the first sample to the end of the last sample. The formula is: Throughput = (number of requests) / (total time).

Storage Node metrics using RING grafana dashboards(http:///stats/):

  • Docker Image size

  • RAM/CPU/Disk usage

  • Report numbers to Product for tooling adjustments.
