NPE while accessing actuator endpoints via InstanceProxy #715

Closed matthjes closed 6 years ago

matthjes commented 6 years ago

Hi,

I'm using the snapshot version of Spring Boot Admin (2.0.0-SNAPSHOT) and there are sometimes errors shown the the browser log:

XML Parsing Error: no root element found
Location: http://localhost:8100/instances/4b9c303acb7f/actuator/metrics/jvm.memory.max?tag=area:nonheap
Line Number 1, Column 1:
jvm.memory.max:1:1
Unhandled promise rejection 
Error: Network Error
Stack trace:
./node_modules/axios/lib/core/createError.js/e.exports@http://localhost:8100/assets/js/vendors.js:5:34303
./node_modules/axios/lib/adapters/xhr.js/e.exports/</_.onerror@http://localhost:8100/assets/js/vendors.js:5:30137

Sometimes everything looks fine, but after a browser refresh there are red errors shown on the web page ("error fetching metrics", something like this). After the next refresh everything is fine.

When I add security (login) to the admin then those errors cause the web page to show the login page again.

I can access the endpoint (e.g. /metrics/jvm.memory.max?tag=area:nonheap) of my application when I call the respective endpoint directly.

Edit: I can see the following error message in my log ("An existing connection was aborted by the host"):

Clicking on the "Details" tab leads to this error:

The ui doesn't support CSRF you need to disable this in your security config

matthjes commented 6 years ago

Hm, CSRF is disabled in the client:

http.csrf().disable()
  .authorizeRequests()
  .antMatchers("/ping").permitAll()
  .antMatchers("/systemstatus").permitAll()
  .antMatchers(webConfiguration.getEndpointV1()).permitAll()
  .antMatchers(webConfiguration.getEndpointV2()).permitAll()
  .anyRequest().authenticated().and()
  .httpBasic();

It's also disabled in the admin (I'm using the example from here: https://github.com/codecentric/spring-boot-admin/blob/master/spring-boot-admin-samples/spring-boot-admin-sample-servlet/src/main/java/de/codecentric/boot/admin/SpringBootAdminApplication.java)

joshiste commented 6 years ago

Please provide a github project which reproduces the issue

joshiste commented 6 years ago

Error Fetching System Load failed: is totally fine and won't be shown in the ui as not every platform provides the system load metric

matthjes commented 6 years ago

Here is a small example project:

https://github.com/matthjes/spring-boot-admin-test

I do not see the NullPointException above, however, I'm getting logged out very frequently when an error occurs.

matthjes commented 6 years ago

Attached you'll find an error log (FireFox). Chrome and IE show the same behavior. error_log.txt

joshiste commented 6 years ago

The weird NPE is fixed with https://github.com/codecentric/spring-boot-admin/commit/553c88005ae0f25f18fa62ca902d8ed3a1864521
