Our network includes more than 650 switches, 650 access points, 275 virtual servers, 75 physical servers, 3,800 desktop computers, and hundreds of other client devices. Historically, we didn’t have great visibility into application performance in our data center or on other client devices. We previously were very reactive to performance problems and used a variety of complex tools like packet sniffers to analyze problems. We needed a solution that could immediately tell us how applications were performing and help us quickly solve problems if they emerge.
Visual TruView enables us to gather key data sets—including packet storage, application response time, transactional decode, flow and SNMP—to highlight performance metrics for key applications. It delivers this information through a centralized console and provides us with a clear picture of performance. When issues arise, it helps quickly isolate the root cause by allowing us to immediately drill down into packet-level detail, and its integration with OptiView XG allows us to conduct real-time, inline packet capture for more sophisticated transactional analysis.
TruView allows us to ensure application performance by collecting and correlating all of the application information and presenting that information through a central monitoring dashboard. If a problem arises, we’re just a click or two away from diving into packet level details, so we can troubleshoot instantly.
Visual TruView allows us to:
For example, our team was recently called in to troubleshoot a database connection issue with Oracle. We were trying to transfer large amounts of data from physical servers to virtual ones, but it kept failing. Because of the data center’s history, our first assumption was that the core was the problem, but we could not isolate the issue. Using TruView we immediately identified the problem as a setting in the Oracle application, not with the data center core, so we modified the setting and quickly resolved the problem.
We had another issue with our SMTP server being hit by an attack, telling it to flood another server with emails. The security team locked down the firewall and claimed the attack was coming from inside the network. We created an application that could capture the SMTP traffic to the server and then analyzed it to find out the attack was coming from an IP in Amsterdam, not internally as initially assumed.
TrueView is very intuitive, and because it gives you real-time visibility and historical data, our troubleshooting flexibility is very robust and amazingly accurate. If a user complains about an issue, we can look at historical data to isolate the problem fast. We couldn’t do that before. If application performance is slow, we can instantly isolate the domain and identify whether it’s a network or application issue. Again, we couldn’t do that before.
