We have a few web servers with around 400 websites in total. For these web servers we use the monitoring system Bosun in combination with exceptinal and opserver (created by stack exchange). We would like to add Http health checks to the monitoring system to ensure all are websites are up and running.
I've seen the 'httpUnit' package which can be used for this purpose and it should be able to add this information to bosun / opserver.
As bosun was set up by our old systems administrator I do not have a lot of experience in this area setting up or adding something to bosun / opserver. Can someone help me find an implementation guide of point me in the right direction for implementing such a system?
I do not have a strong preference for httpUnit, so other solutions for monitoring a websites uptime are welcome
