---------------------------------------
Summary: Alerts Need HA Mode Dynamic Property Support For WEB and
METRIC
Key: AMBARI-9848
URL: https://issues.apache.org/jira/browse/AMBARI-9848
Project: Ambari
Issue Type: Task
Components: ambari-agent, ambari-server
Affects Versions: 2.0.0
Reporter: Jonathan Hurley
Assignee: Jonathan Hurley
Fix For: 2.0.0
Alerts for services that support a standard HA mode (nameservice and/or alias)
need to be able to understand how to calculate the correct server to contact.
This means building a dynamic key to use when discovering the URL to use for
METRIC and WEB alerts.
The proposal is to add a new child element to the URL parameter:
{code}
"high_availability": {
"nameservice": "{{hdfs-site/dfs.nameservices}}",
"alias_key" : "{{hdfs-site/dfs.ha.namenodes.{{ha-nameservice}}}}",
"http_pattern" :
"{{hdfs-site/dfs.namenode.http-address.{{ha-nameservice}}.{{alias}}}}",
"https_pattern" :
"{{hdfs-site/dfs.namenode.https-address.{{ha-nameservice}}.{{alias}}}}"
{code}
