@dilsheer, provided you have access you can try the following REST API call for getting the details for Triggered Alerts, including Triggered Time:
| rest /servicesNS/<ownerRole>/<yourSplunkAppName>/alerts/fired_alerts/<yourAlertNameURLEncoded>
| dedup "eai:acl.owner" "eai:acl.app" savedsearch_name
| search "eai:acl.owner"="<ownerRole>" "eai:acl.app"="<yourSplunkAppName>" savedsearch_name="<yourAlertNameAsIs>"
| table savedsearch_name "eai:acl.owner" "eai:acl.app" trigger_time id
Please find the Splunk Documentation for corresponding REST API: http://docs.splunk.com/Documentation/Splunk/latest/RESTREF/RESTsearch#alerts.2Ffired_alerts.2F.7Bnam...
PS:
{Name}
in REST, make sure you have it URL Encoded i.e. space
becomes %20
.Enabled
.<ownerRole>
, <yourSplunkAppName>
, <yourAlertNameURLEncoded>
and <yourAlertNameAsIs>
with what you have in your system.
