What is most valuable?
I like its scalability thanks to slaves. You can add as many slave as you want, which also allows you to reach and monitor devices running on the network that are not accessible by the master. It also has good roles management which is very useful for a service provided to customers. Lastly, it also has a nice GUI.
How has it helped my organization?
Before we used Nagios. It's based on Nagios too, but the biggest benefit when compared to it is the simplicity to set up and modify devices.
What needs improvement?
SNMP traps management to be improved. It's not so easy to use and you have to pay more to get the SMS module.
For how long have I used the solution?
I've been using it for 30 months.
What was my experience with deployment of the solution?
We have had no issues with the deployment.
What do I think about the stability of the solution?
There have been no performance issues.
What do I think about the scalability of the solution?
It's been able to scale for our needs.
Which solution did I use previously and why did I switch?
We used Nagios previously, and it was reliable but hard to configure, and even harder to create a master/slave configuration.
How was the initial setup?
Considering the complexity of our network, it wasn't hard to install. It would be preferable if you have some Linux knowledge prior to the implementation.
What about the implementation team?
We implemented it in-house via our Data Center Team.
What's my experience with pricing, setup cost, and licensing?
As a CSP, we have an MSP agreement so that we can pay for its use. It means that additional customers will pay additional fees, and this is invaluable.
What other advice do I have?
Get a good book so you can get exposed to all the great functionality in PostgreSQL. I would highly recommend looking at the postgresql.conf configuration settings when you are ready to go into production. In order to get a good price, I think that you need to have a commercial process in place.
