Apache Monitoring
Apache HTTP server traditionally serves billions of web pages worldwide. Both SMBs and large corporations use it as a strong foundation for their web infrastructure.
AggreGate Network Manager provides the in-depth Apache server availability, response time and performance monitoring. The Apache monitoring dashboard provides statistical information for the following Apache-specific KPIs:
| Server name | Server version |
| Listened ports | Uptime |
| Total traffic | Total served pages |
| Busy processes | Idle processes |
| Number of requests per second | Current traffic |
Most of the above metrics are available as spot values and trends. Additionally, the Apache monitoring dashboard renders detailed statistics for the following HTTP errors:
- Bad Request
HTTP code 400 - Forbidden
HTTP code 403 - Not Found
HTTP code 404 - Method Not Allowed
HTTP code 405 - Internal Server Error
HTTP code 500 - Not Implemented
HTTP code 501 - HTTP Version Not Supported
HTTP code 505
