I'd like to learn more about the exact differences between HP SiteScope and dynaTrace.
Which one is better to monitor resources?
SiteScope is more of an ITOM tool, in my opinion. Comparing to a true APM tool, SiteScope is lacking on several fronts. Comparing to Dynatrace APM, it doesn't even come close to matching on most fronts.
Just to add to some of the comments regarding dynaTrace. So far those are all correct. I just want to add, dynaTrace also has the capability to perform agent-less monitoring as well. Some of the things we used SiteScope for (url monitoring, log file monitoring, etc.) we were able to transition into dynaTrace allowing us to get rid of SiteScope altogether due to it's ability to develop custom plugins which allows you to really do a lot of extra things that aren't available out of the box which I take advantage of everyday.
Thank you very much to one and all.
Sorry, don't really have a lot of exposure to either of the products.
Sitescope is a bottum up (technical) monitoring tool. It is agentless. Advantages: 1) with a user account/password you can monitor your systems so a fast realization of technical monitoring. 2) you don't have to install an agent (prevent the "not invented by us syndrome" most admins have 3) it provides out of the box monitors for different technologies. You don't have to develop scripts first to enable monitoring 4) it's a perfect tool for setting up performance tests fast, it integrates in Loadrunner (this means that doing analysis is not delayed by importing technical metrics from other parties) 5) you can work independant from other silo's during performance tests. 6) history of metrics. Disadvantage 1) If there is no connectivity between Sitescope and the monitoring object there is no data collected 2) it samples, just like any other monitoring tool and so you miss the reason of time outs.
dynaTrace: is a 3 rd gen diagnostic tool. It's approach is the end user experience (top down approach). So it measures each individual session of each individual end user across the chain and measures where the response times is consumed. From that point you can drill down into the application layer where Sitescope is not able to do any monitoring at all. Sitescope only reaches the OS and Middleware layers, not the application layer. By drill down I mean: into the application code. You know exactly which application code is due to latency, which database calls are executed (SQL query) how many times and how that is related to the overall response time. Since version 5.5 you could also hook up technical metrics like the Windows Resource Counters, Websphere PMI metrics etc. So there is some overlap with Sitescope. dynaTRace is used to deploy across your DTAP and provides one reference point: the end user. There is no fingerpointing/blame game anymore: it gives you 100% grip and control, also in (synmchronous) messaging environments like Tibco. Besides the diagnostic functionality it embodies the ultimate monitoring maturity stack (BAM, Passive Monitoring, Active Monitoring, Technical Monitoring, Logfile monitoring). Minimal instrumenting, it doesn't sample in contradiction to AppDynamics. Besides Java and .NET, an ADK is available to build a custom Agent. Also a z/OS mainframe agent is available. Since version 6.0 (latest version) you can also import Wireshark measurements. dynaTrace hooksup with Gomeze SaaS (Active Monitoring outside customer premises) and DC RUM (Passive monitioring on customer premises infra)
With dynaTrace you save a lot of money regarding the required test cycles to find the root cause. With Sitescope the risk is bigger
It depents on what you customer's demand is: 1) Do you want to monitor only? 2) Do you want to monitor and solve the problem? 3) Is it part of Continuous Delivery?
If 1) there are other alternatives available (Open Source Graphite)
If 2+3 ) dynaTrace
SiteScope is an agentless Infrastructure monitoring tool. It has a wide range of monitoring capabilities including Server,DB’s,Middleware,Network and application’s as well. Its very easy to deploy & configure.
Dynatrace is more application level monitoring. Its an agent based solution for java & Net applications. Its able to monitor transactions at thread level with deep drill down capabilities.
The solutioning will be based on the monitoring requirements, scope, cost & scalability.
The solutions have different purposes. I think it's better to summary both of them.
The HP SiteScope is a tool to monitor infrastructure components without agents. It monitors availability and some performance metrics of infrastructure elements. The metrics can be visualized by service model, so you can see which components are being affected.
dynaTrace monitors the application performance through agents. Applications developed by Java, .NET and PHP and also mobile applications are instrumented by the agents and monitored automatically. The monitoring covers 100% (all) transactions, providing traceability and point the problem. dynaTrace accelerates the troubleshooting, monitors end user experience, increase the collaboration between teams (dev, QA, prod, architectures), monitors business transaction effetivelly and also monitors infrastructure elements.
