Service health has been monitored and visual insights support proactive telecom operations

Senior Consultant at a consultancy with 10,001+ employees

The installation process is the first aspect I dislike about Splunk ITSI (IT Service Intelligence). If you do not configure it correctly, you will encounter issues in the search head. Because we use a distributed environment where each component has its own specific roles, installation is critical and requires careful attention. Splunk ITSI (IT Service Intelligence) is built with many applications. It is a compressed file, and when you extract the Splunk ITSI (IT Service Intelligence) app, you receive approximately 19 apps. Some applications, add-ons, and packages must be installed on specific components. If you do not configure an application correctly, it will not work. Sometimes we encounter issues during installation because of this complexity. I believe the installation process should be more uniform, meaning it could be deployed across all components to avoid post-installation issues. Sometimes after installation, you receive errors, and users cannot access Splunk ITSI (IT Service Intelligence). We have experienced this type of issue due to installation errors. I believe there is currently room for improvement regarding scalability. When we create Glass Tables containing many searches, the Glass Tables sometimes fail due to memory constraints, and we receive error pages. Splunk ITSI (IT Service Intelligence) should have a lightweight version to address these concerns. I would rate current scalability as medium.

Unified monitoring has reduced outages and enables proactive fixes with automated remediation

Developer at a financial services firm with 501-1,000 employees

My favorite best feature is the ability to manage complex hybrid environments from a single dashboard. Zabbix natively supports monitoring everything from Linux servers and Windows servers to network devices and cloud infrastructure. The view I rely on the most on a day-to-day basis is a custom dashboard combining the problem widget and graph widget. The problem widget gives me an immediate filtered snapshot of the active alerts across all our servers. I pair that with the graph widget, which allows me to track performance metrics and compare values over time, such as monitoring storage and capacity trends on our Synology appliance. Having all of this in a single pane of glass saves me from constantly digging through logs. I also rely heavily on custom dashboards that combine the problem widget and the top host widget. The problem widget gives me an immediate filtered list of any active alerts across the entire environment. I pair that with the top host widget, which instantly shows me which servers are consuming the highest resources. Having all of these related metrics side-by-side in a single view allows me to spot the issue and identify the exact server causing it without having to dig through separate tools. Zabbix has built-in machine learning for continuous anomaly detection and proactive trend prediction. It establishes a baseline by analyzing historical data, allowing it to forecast impending issues, such as predicting exactly when a system will run out of resources before critical thresholds are breached. From a governance and security perspective, it delivers enterprise-grade security by supporting full data encryption and integration with external secret vaults to protect sensitive credentials. From a governance perspective, it features detailed configuration change tracking and role-based user permissions, which allows administrators to secure different teams or tenants within a single environment. Regarding accuracy, Zabbix's proactive alerts are highly accurate and trustworthy, provided they are fed enough historical data to establish a solid baseline. Regarding reliability and output, the prediction outputs are extremely reliable because Zabbix relies on transparent statistical mathematics, such as standard deviation and weighted moving averages, rather than a closed black box AI model. The straightforward statistical approach allows administrators to forecast value reliability and predict exactly how much time they have before a system reaches a critical problem threshold.
