Created a new correlation search in ES. But sometimes the mail is not delivered to the mentioned mailid

[RanjiRaje]

Hi, I have a correlation search created in Enterprise security. Scheduled as below.

Mode: guided

Time range> Earliest: -24h, Latest: Now, Cron: 0 03 * * *, scheduling: realtime, schedule window: auto, priority: auto

Trigger alert when greater than 0

Throttling > window duration: 0

Response action > To:mymailid, priority: normal, Include: Link to alert, link to result, trigger condition, attach csv, Trigger time

In this case, mail is not getting delivered regularly. If I try executing the same SPL query in search, it showing more than 300 rows result

Confirm the alerts are firing

| rest splunk_server=local /serviceNS/-/-/alerts/fired_alerts

Check the _internal index for errors sending alerts to your email provider.

index=_internal "sendemail"

Check with your email provider/admin to see what is happening to the alerts before they get your mailbox.  As always, check your Spam folder.

Hi Sir, thanks for your valuable suggestions. I tried the below SPL 

index=_internal "sendemail"

I received 1 event with details like "Sending email" (As I said already, I received an alert mail to my mailbox once and after that it stopped sending mail).

Continuation... as I said, received mail once but later then, stopped receiving mail. Please help me on this further. Thanks

If there are no errors in the Splunk logs relating to sending email then there must be something happening to the messages after they leave Splunk.  Check your Spam folder and any automatic actions you may have.

Have you confirmed the alerts are firing?

Hi @RanjiRaje ,

don't use scheduling real time.

Ciao.
