I am trying out one of the watcher examples given here: [https://www.elastic.co/guide/en/watcher/current/watching-marvel-data.html#watching-cpu-usage](https://www.elastic.co/guide/en/watcher/current/watching-marvel-data.html#watching-cpu-usage). I have configured exchange using the guide: [https://www.elastic.co/guide/en/watcher/current/email-services.html#exchange](https://www.elastic.co/guide/en/watcher/current/email-services.html#exchange). ``` watcher.actions.email.service.account: exchange: email_defaults: from: from@domain.com profile: outlook smtp: auth: true starttls.enable: true host: email.host.server port: 443 user: username password: "password" ``` I get the following error message when the watch triggers an alert: ``` [2015-06-13 14:16:34,871][ERROR][watcher.actions.email] [transport_client_host] failed to execute action [cpu_usage/send_email] org.elasticsearch.watcher.actions.email.service.EmailException: failed to send email with subject [Watcher Notification - HIGH CPU USAGE] via account [exchange] at org.elasticsearch.watcher.actions.email.service.InternalEmailService.send(InternalEmailService.java:86) at org.elasticsearch.watcher.actions.email.service.InternalEmailService.send(InternalEmailService.java:78) at org.elasticsearch.watcher.actions.email.ExecutableEmailAction.execute(ExecutableEmailAction.java:64) at org.elasticsearch.watcher.actions.ActionWrapper.execute(ActionWrapper.java:100) at org.elasticsearch.watcher.execution.ExecutionService.executeInner(ExecutionService.java:340) at org.elasticsearch.watcher.execution.ExecutionService$WatchExecutionTask.run(ExecutionService.java:392) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) Caused by: javax.mail.MessagingException: Exception reading response; nested exception is: java.net.SocketException: Connection reset at com.sun.mail.smtp.SMTPTransport.readServerResponse(SMTPTransport.java:2153) at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1912) at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:638) at javax.mail.Service.connect(Service.java:295) at org.elasticsearch.watcher.actions.email.service.Account.send(Account.java:99) at org.elasticsearch.watcher.actions.email.service.InternalEmailService.send(InternalEmailService.java:84) ... 8 more Caused by: java.net.SocketException: Connection reset at java.net.SocketInputStream.read(SocketInputStream.java:196) at java.net.SocketInputStream.read(SocketInputStream.java:122) at com.sun.mail.util.TraceInputStream.read(TraceInputStream.java:110) at java.io.BufferedInputStream.fill(BufferedInputStream.java:235) at java.io.BufferedInputStream.read(BufferedInputStream.java:254) at com.sun.mail.util.LineInputStream.readLine(LineInputStream.java:89) at com.sun.mail.smtp.SMTPTransport.readServerResponse(SMTPTransport.java:2131) ... 13 more ``` Not sure what is missing. One thing that I do notice is that my exchange server host in my mail client (like apple mail or outlook) is actually defined as email.host.server/EWS/Exchange.asmx but when I used this I get the following error: ``` [2015-06-13 14:32:39,173][ERROR][watcher.actions.email] [transport_client_host] failed to execute action [cpu_usage/send_email] org.elasticsearch.watcher.actions.email.service.EmailException: failed to send email with subject [Watcher Notification - HIGH CPU USAGE] via account [exchange] at org.elasticsearch.watcher.actions.email.service.InternalEmailService.send(InternalEmailService.java:86) at org.elasticsearch.watcher.actions.email.service.InternalEmailService.send(InternalEmailService.java:78) at org.elasticsearch.watcher.actions.email.ExecutableEmailAction.execute(ExecutableEmailAction.java:64) at org.elasticsearch.watcher.actions.ActionWrapper.execute(ActionWrapper.java:100) at org.elasticsearch.watcher.execution.ExecutionService.executeInner(ExecutionService.java:340) at org.elasticsearch.watcher.execution.ExecutionService$WatchExecutionTask.run(ExecutionService.java:392) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) Caused by: javax.mail.MessagingException: Unknown SMTP host: email.host.server/EWS/Exchange.asmx; nested exception is: java.net.UnknownHostException: email.host.server/EWS/Exchange.asmx at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1932) at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:638) at javax.mail.Service.connect(Service.java:295) at org.elasticsearch.watcher.actions.email.service.Account.send(Account.java:99) at org.elasticsearch.watcher.actions.email.service.InternalEmailService.send(InternalEmailService.java:84) ... 8 more Caused by: java.net.UnknownHostException: email.host.server/EWS/Exchange.asmx at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:178) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:579) at java.net.Socket.connect(Socket.java:528) at com.sun.mail.util.SocketFetcher.createSocket(SocketFetcher.java:288) at com.sun.mail.util.SocketFetcher.getSocket(SocketFetcher.java:231) at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1900) ... 12 more ``` Any idea what could be missing? For server urls like email.host.server/EWS/Exchange.asmx should there be another path parameter defined so that one can configure the path separately? something like: smtp.host: email.host.server smtp.host.path: /EWS/Exhange.asmx ---

Based on this link: [https://scottlinux.com/2014/06/05/check-for-smtp-tls-from-command-line-with-openssl/](https://scottlinux.com/2014/06/05/check-for-smtp-tls-from-command-line-with-openssl/), it appears like my mail server does not support SMPT-TLS. Does it mean that watcher cannot work with my setup? Any suggestions? ``` CONNECTED(00000003) didn't found starttls in server response, try anyway... write:errno=32 --- no peer certificate available --- No client certificate CA names sent --- SSL handshake has read 0 bytes and written 0 bytes --- New, (NONE), Cipher is (NONE) Secure Renegotiation IS NOT supported Compression: NONE Expansion: NONE --- ``` ---

Alright... the following setting works for me: ``` watcher.actions.email.service.account: exchange: email_defaults: from: $your.from.address profile: exchange smtp: auth: false starttls.enable: false host: $your.mail.server port: $your.port ``` ---
