This HTTP server has been improved from the last Active SNMP release. There is the new effective cache management, the authentication management and other internal improvements. It brings faster and more reliable access to SNMP information. Tuning the Active SNMP Performance Creating graphs requires periodical reading of SNMP variables on background. These background processes use system resources - threads and memory, of course.
More graphs consume more system resources.
Therefore Active SNMP 2.0 provides a means to limit system resources usage. And, to tune it, e.g. assign more resources to the application if your system's computing power is great enough. When a request for reading an SNMP value arrives, Active SNMP hands it to one of its event processing threads. Active SNMP creates threads on an 'as needed' basis until it reaches the Maximum Threads counter. The Buffered Events counter indicates the number of events waiting for a processing thread to become available.
