-----------------------------------------
Summary: Add heartbeat adaptor to push chukwa agent status to
remote http server
Key: CHUKWA-737
URL: https://issues.apache.org/jira/browse/CHUKWA-737
Project: Chukwa
Issue Type: Improvement
Components: Data Collection
Affects Versions: 0.7.0
Reporter: shreyas subramanya
Assignee: shreyas subramanya
Provide a generic HeartbeatAdaptor which can periodically send status reports
to a remote http server. The adaptor can be configured with arbitrary number of
component status checkers and it will send out a single status report with all
components.
Example - to send out the status of chukwa agent as well as a rest interface
(in this case chukwa agent rest), we add the following adaptor:
add HeartbeatAdaptor DefaultProcessor (ChukwaStatusChecker,HttpStatusChecker
Chukwa.rest.server http://localhost:9090/rest/v1/adaptor) 3 0
This will send out status reports such as -
{"time":1424213621629,"components":[{"host":"host.example.com","component":"Chukwa.Agent","adaptor.count":1},"status":"running","component":"Chukwa.rest.server","uri":"http:\/\/localhost:9090\/rest\/v1"}]}
Additional configuration needed in chukwa-agent-conf.xml
chukwa.http.writer.host
chukwa.http.writer.port
if PipelineConnector is used, add
org.apache.hadoop.chukwa.datacollection.writer.HttpWriter to head of pipeline
