It is a good product that is robust. They have a free version that makes the value good. If it cost money then the install and plugins would need polishing. But overall it is a good product that does what it says it does. But definitely not for beginners you do need some knowledge to set it up and get it running
I'm using Entuity, and using BMC Operations Management to manage events is a must. Assign, acknowledging, close events, send notifications, and use REST API for external/internal connectors is a big plus! However, I'll not recommend it for small companies, due to the infrastructure and the huge amount of features it has.
Centreon does a good job against these products. Of courseCentreon can be free and that is what we used. So it is not quite the same the other products are more polished and support is readily available. But Centreon is still good and if you have some knowledge can work just as well
We have done extensive comparisons between the products and some where quickly eliminated for lacking functionality or support for key technologies. The features that really pushed TrueSight to the top over other full suites from CA, ScienceLogic, SolarWinds, HP, Foglight and IBM was a mix of deal-breaking gaps for us in areas including support of iSeries, QoS reporting, integration options to other platforms and advanced analytics with event management
