Newwork And Collaboration Supervisor at Nafeza
Monitoring has improved bandwidth insights and application diagnosis but setup and costs still need work
They need room for improvement about the spare parts. There are shortages in Egypt in their stock. We tried to make RMA for specific parts, and it took a long time. Comparing this to a vendor like Cisco, who provides any component next business day, NETSCOUT nGeniusONE took a long time. This needs more improvement. I believe it is expensive. They need to reduce its budget a little bit. Comparing to other solutions, it is very expensive.

Senior Consultant at a consultancy with 10,001+ employees
Service health has been monitored and visual insights support proactive telecom operations
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.
