Director at Techpace
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.

Helps reduce response time but has room to improve customization complexity
We are not working on simple standalone solutions like Kaspersky DDoS Protection or Hybrid Cloud Security. Once you understand Zabbix, then it is easy to customize those web pages and graphs for our customer use. It is fully automated to your requirements. Zabbix is working fine with no issues, and I am satisfied with it. We have combined Zabbix and SolarWinds. The integration works fine, and it is easy to integrate Zabbix with the IT environment. We were trying to purchase MDR (Managed Detection and Response), but we are not working on that. I don't have real experience with MDR. We are using Falcon software for that. We are working with Falcon Complete, not with Sandbox. We are not using Kaspersky for business or cloud protection. For that, we are using Zabbix CrowdStrike Falcon Complete solution. I have given this review an overall rating of 8.

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
