Monitoring setup for a web application and database server
In the previous section, we have discussed the types of monitors, but still we don't know which monitors are configured on these systems. Let's prepare a table for the different infrastructure system monitors and why they are configured. The following table shows the basic monitors, which are normally configured for web application and database servers:
