![]() However, Splunk can help join these dots to quickly perform a root cause analysis, and report metrics and KPIs on the service or process being monitored.Ĭommon Splunk search commands for combining events are transaction or stats. In this complex transaction, it can be tricky to quickly find the source of the problem. If something goes wrong in any of these systems, the payment might not go through. This real world event triggers a flurry of events in a large number of systems with the card provider, the bank, and the retailer before the transaction is fully settled. Imagine a customer tapping their bank card on a payment terminal to purchase something in a shop. This concept is extremely useful if you want to link multiple events across data sources, that all relate to the same real world event. ![]() Splunk can also combine multiple events to visualize transactions, business processes and sessions.

Splunk puts a variety of tools in your hand but without proper knowledge, every tool becomes a hammer. Splunk Administrators can monitor Splunk Alerts periodically to see whether any alerts are failing to send emails or any external alerting tools integrations are not working. These two searches can be setup as their own alert, but I would recommend setting these up on an Alert Monitoring dashboard. | stats values(action) as alert_action count(eval(alert_status=“failed”)) as failed_count count(eval(alert_status=“success”) as success_count latest(event_message) as failure_reason by search, _time | eval event_message = mvjoin(event_message, “ -> “) | table _time search action alert_status app owner code duration event_message | eval alert_status = if(code=0, “success”, “failed”) | transaction action date_hour date_minute startswith=“Invoking” endswith=“exit code” The second (below) search looks through the internal logs to find errors while sending alerts using alert actions to external alerting tools/integrations Subject - Subject of the email - by default it is Splunk Alert: Įrror_message - Message describing why the alert failed to send email Host - The host the alert is saved/run on Note: Please replace with the name of your search head(s), wildcards will also work. ![]() | stats count values(host) as host by subject, rec_mail, error_message | transaction startswith=“Sending email.” endswith=“while sending mail to” Index=_internal host= sourcetype=splunk_python ERROR You can use the information in the results of The first search looks at email alerts and will tell you by subject which alert did not go through. Please note that the user running the searches need to have access to the “_internal” index in Splunk. Alert actions can fail because of multiple reasons, and Splunk internal logs will be able to capture most of those reasons as long as proper logging is set in the alert action script. The following two searches can help users understand if any triggered alerts are not sending emails or the alert action is failing. This can be inconvenient for users and if the alerts are used to monitor critical services, this can have a financial impact as well and can prove to be costly if alerts are not received on time. There are times that they may fail due to different reasons and a user may not get the intended alert they set up. Users can also create their own custom alert actions which can help them respond to alerts or integrate with external alerting or MoM tools. Other Splunk TAs also help users integrate external alerting tools like PagerDuty, creating JIRA tickets, and many other things using these tools. Some standard alert actions are to send an email, add to triggered alerts, etc. Triggered alerts call alert actions which can help owners respond to alerts. Alerts trigger when the search meets specific conditions specified by the alert owner. Scheduled alerts are more commonplace and are frequently used. Splunk Alerts use a saved search to look for events, this can be in real-time (if enabled) or on a schedule. ![]() I have observed almost every Splunker monitor Splunk Alerts for errors. In the past few years, Splunk has become a very powerful tool to help teams in organizations proactively analyze their log data for reactive and proactive actions in a plethora of use cases.
