My company is currently looking to replace our current solution used for monitoring our web-based enterprise solutions for both up-time and performance. Please note this is not intended to be a network monitoring-type solution (internally we currently use Nagios). If anyone has a provider that they have had a positive experience with, it would be much appreciated. Here is a list of our requirements: • Must have a large number of probes/agents around the globe to be representative of our customer base • Must have a flexible scripting capability to automate multi-step user actions • 24 hour a day monitoring • Flexible alerting system • Report generation capability • Mimic browser specific monitoring (optional, not a must-have)
