I noticed that this is displayed as part of the HTTPD process properties, despite the AppMon agent LoadModule being commented out in httpd.conf. I want to know under what conditions will this message be triggered and displayed? Does it also disable agents from other vendors as well?
It disables any common known agents that do the same type of injection for monitoring as there can be issues with both being present. This includes AppMon but other vendors as well, I have not seen an exhaustive list but most of the big names are included.
Yeah, we are seeing this despite commenting out LoadModule dtagent_module... from httpd.conf of the affected server. This means the appmon modules are no longer loaded along in the Apache HTTPD process. It would be interesting to see which other modules are automatically unloaded as well.
