13 The @arvados-client diagnostics@ command exercises basic cluster functionality, and identifies some common installation and configuration problems. Especially after upgrading or reconfiguring Arvados or server/network infrastructure, it can be the quickest way to identify problems.
15 h2. Using system privileges
17 On a server node, it is easiest to run the diagnostics command with system privileges. The word @sudo@ here instructs the @arvados-client@ command to load @Controller.ExternalURL@ and @SystemRootToken@ from @/etc/arvados/config.yml@ and use those credentials to run tests with system privileges.
19 When run this way, diagnostics will also include "health checks":health-checks.html.
22 # <span class="userinput">arvados-client sudo diagnostics</span>
25 h2. Using regular user privileges
27 On any node (server node, shell node, or a workstation outside the system network), you can also run diagnostics by setting the usual @ARVADOS_API_HOST@ and @ARVADOS_API_TOKEN@ environment variables. Typically this is done with a regular user account.
30 $ <span class="userinput">export ARVADOS_API_HOST=zzzzz.arvadosapi.com</span>
31 $ <span class="userinput">export ARVADOS_API_TOKEN=xxxxxxxxxx</span>
32 $ <span class="userinput">arvados-client diagnostics</span>
35 h2. Internal/external client detection
37 The diagnostics output indicates whether its client connection is categorized by the server as internal or external. If you run diagnostics automatically with cron or a monitoring tool, you can use the @-internal-client@ or @-external-client@ flag to specify how you _expect_ the client to be categorized, and the test will fail otherwise. Example:
40 # <span class="userinput">arvados-client sudo diagnostics -internal-client</span>
43 --- cut here --- error summary ---
45 ERROR 60: checking internal/external client detection (11 ms): expecting internal=true external=false, but found internal=false external=true
51 # <span class="userinput">arvados-client sudo diagnostics</span>
