Identifying complex diagnostics and alert management improvements needed
The best features of Splunk ITSI (IT Service Intelligence) are the APM, the Application Performance Monitoring, and the diagnostic capabilities. It is state-of-the-art. The intelligent alerting in Splunk ITSI (IT Service Intelligence) is very good. The predictive analysis can give you proactive information about potential bottlenecks that can occur on applications, desk, storage, SQL servers, databases, or other systems. It is very effective. The customizable dashboards in Splunk ITSI (IT Service Intelligence) facilitate our customers because they are highly adaptable. We have multiple types of dashboards, depending on who will be utilizing them, such as engineering, middle management, IT heads, or NOC teams that will be monitoring systems. The metrics I rely on for monitoring in Splunk ITSI (IT Service Intelligence) depend on what kind of asset or CI we are monitoring. For applications, we have the number of concurrent transactions, response time from the database, and write time on the desk. There are multiple parameters and metrics that we utilize in the monitoring part within ITSI.

Getting up and running is easy, even for a newbie but management of searches definitely needs improvement
Operational effectiveness with regards to when there's an issue, when there's a reactive issue, people are able to, or as well as proactively, actually, because we use their PagerDuty integrations. We use queries in Sumo Logic to trigger alerts based on logging. That allows us to proactively identify issues as they're happening. With those same alerts, obviously, with that platform, you can use it to reactively start looking at troubleshooting issues as they're happening right then and there or incidents. So it's been very, very good for alerting and for troubleshooting issues. For predicting issues before they happen, it is not very good. They have a feature called anomaly detection, but I think it's quite premature compared to other stuff out there. So it's good for alerts and for troubleshooting operational effectiveness. When your operations are down or segregated, it's perfect because it will help you diagnose the issues.
