Category: Domain: Server/Host Monitoring, Vendor: Empire/SystemEDGE, Web and Application Servers

Description: Empire SystemEDGE Apache module MIB for monitoring Apache HTTP server performance metrics including requests and connection statistics.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is EMPIRE-APACHEMOD?

EMPIRE-APACHEMOD is a vendor-specific Empire Technologies MIB module extending the SystemEDGE systems management agent to monitor the Apache HTTP Server. Per its purpose, it exposes web server performance metrics such as request rates and connection statistics, layered on top of the general host-monitoring data SystemEDGE already provides. This ties directly into software status monitoring of a running Apache service, since request throughput and connection counts are primary indicators of whether the web server is healthy, overloaded, or hung. As a SystemEDGE add-on module, it depends on the base SystemEDGE agent MIB for host identification and general system monitoring context. It is typically deployed on servers running Apache HTTP Server that are already managed by an Empire SystemEDGE agent. Engineers can download the EMPIRE-APACHEMOD file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EMPIRE-APACHEMOD. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Server running Apache HTTP Server, monitored via Empire SystemEDGE agent

Monitoring Examples

No object or table names were extracted from the source for this module, so a specific polling example cannot be grounded to real identifiers; per its stated purpose, an admin would typically poll this module for Apache request rate, active connection counts, and server process/worker status to detect a web server overload or hung worker condition, alerting when request throughput drops or connections spike unexpectedly.

What Can Be Monitored

Apache request rate
active connection count
server process/worker status
