When you start skedler-alerts and if you see the following error in the console or in alert log (alert.log):

root@41911f656327:/opt/alert/# bin/alert
LD_LIBRARY_PATH configured
LD_LIBRARY_PATH = /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64:/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/server
{ err:
   { [Error: Request Timeout after 1500ms]
     status: undefined,
     displayName: 'RequestTimeout',
     message: 'Request Timeout after 1500ms',
     body: false } }
Some error occured, exiting.

Please do the following to resolve this issue:

  1. Check whether elasticsearch_url  has been configured correctly in <alert_home>/config/alertconfig.yml
  2. Run the following command on the server where Skedler-Alerts runs and check whether you are able to connect Elasticsearch server

     sudo curl -XGET <Elasticsearch URL>

If you are not able to connect to Elasticsearch server check for the connectivity and then configure the Elasticsearch URL that connects to the Elasticsearch server in <alert_home>/config/alertconfig.yml.
