Java Spring Boot 2 application collector
This module monitors one or more Java Spring-boot 2 applications depending on configuration. Netdata can be used to monitor running Java Spring Boot 2 applications that expose their metrics with the use of the Spring Boot Actuator included in Spring Boot library.
Springboot2 module looks up http://localhost:8080/actuator/prometheus
and http://127.0.0.1:8080/actuator/prometheus
to detect Spring Boot application by default.
Metrics
All metrics have "springboot2." prefix.
Metric | Scope | Dimensions | Units |
---|---|---|---|
response_codes | global | 1xx, 2xx, 3xx, 4xx, 5xx | requests/s |
thread | global | daemon, total | threads |
heap | global | free, eden, survivor, old | B |
heap_eden | global | used, commited | B |
heap_survivor | global | used, commited | B |
heap_old | global | used, commited | B |
uptime | global | uptime | seconds |
Configuration
Edit the go.d/springboot2.conf
configuration file using edit-config
from the
Netdata config directory, which is typically at /etc/netdata
.
cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/springboot2.conf
The Spring Boot Actuator exposes these metrics over HTTP and is very easy to use:
- add
org.springframework.boot:spring-boot-starter-actuator
andio.micrometer:micrometer-registry-prometheus
to your application dependencies - set
management.endpoints.web.exposure.include=*
in yourapplication.properties
Please refer to the Spring Boot Actuator: Production-ready features and 81. Actuator - Part IX. ‘How-to’ guides for more information.
Here is an example for 2 servers:
jobs:
- name: local
url: http://localhost:8080/actuator/prometheus
- name: remote
url: http://203.0.113.10:8080/actuator/prometheus
For all available options please see module configuration file.
Troubleshooting
To troubleshoot issues with the springboot2
collector, run the go.d.plugin
with the debug option enabled. The output
should give you clues as to why the collector isn't working.
Navigate to the
plugins.d
directory, usually at/usr/libexec/netdata/plugins.d/
. If that's not the case on your system, opennetdata.conf
and look for theplugins
setting under[directories]
.cd /usr/libexec/netdata/plugins.d/
Switch to the
netdata
user.sudo -u netdata -s
Run the
go.d.plugin
to debug the collector:./go.d.plugin -d -m springboot2
