Checks the available free disk space on the logical drive partitions. |
NSClient++ installed/running and version is approved |
NSClient++ running but version is outdated/mismatch |
NSClient++ not responding / not running |
| Uptime |
Monitors the duration the system has been running to detect unexpected reboots or service interruptions. |
Uptime is normal (no unexpected recent reboot) |
Recent reboot detected (within warning window) |
Very recent reboot or unable to read uptime |
| Portscan |
Checks whether specific (expected) ports are open or closed on the server. |
All required ports are in the expected state |
Non-critical port mismatch detected |
Critical port mismatch (required closed/open) detected |
| Network Traffic Embedded |
Monitors data throughput and error rates on the integrated (on-board) network interface. |
Network traffic within expected range |
Traffic unusually high/low or error rate increasing |

Monitors data throughput and performance for network cards installed in specific hardware slots. |
Network traffic within expected range |
Traffic unusually high/low or error rate increasing |
Traffic at critical level or interface down/errors severe |
| PING |
Checks if the server is reachable on the network, measures packet loss, and Round Trip Time (RTA). |
Host reachable with acceptable latency and no/low loss |
Packet loss and/or latency above warning threshold |
Host unreachable or loss/latency at critical level |
| Drive Space |
Checks the available free disk space on all mounted logical drives (e.g., C:, D:). |
