Apache Virtual Host Errors per Minute - Server Monitor
The amount of internal server errors experienced when contacting the Apache virtual host is high. Apache HTTP Server performance may be adversely affected.
Apache internal server errors are problems experienced within the Apache virtual host.
The monitor threshold is analyzed against an average of values returned in polls to the agent where the Number of Samples parameter controls the number of samples included in the calculation of the average.
Apache internal server errors can be caused malformed code running on the server. These errors can also be caused invalid directives in configuration files as well as limitations imposed by file system and server software.
To address Apache server errors on a virtual host choose one or more of the following options:
Ensure that configuration files are properly present and code on the server is able to get correct configuration directives.
Investigate for code problems in the web applications
Confirm that resources the web applications depend on (such as databases) are available
