I need to decide whether I will use SolarWinds or Centerity Monitoring.
Could anyone help me by giving some comparison between these two products?
Well since I've never heard of Centerity before I'd say that's one thing SolarWinds has going for it...
What you trying to figure out - your asking for comparisons but have not asked any questions to give you any data. I can tell you I have been a NOC Manager /SDM for many years and have been using Solarwinds products for most of them .
Companies with thousands and thousands of nodes and interfaces to companies with 100-500 servers and I have no complaints about the product .. I can have it up and running in minutes as long as some prerequisites are met first , easy to use and config , and the data where i need ..
I have not heard about the other company you mention... so not sure what they offer but based on the web site i bet its pricy
From looking at their screen shots, looks like they copied the SolarWinds web console.
I am happy with Solarwinds product..
I don't have any experience with Centerity, but you can use this document to compare multiple vendors in terms of features, function, ease of use, etc:
