What is Health Monitoring?
Health Monitoring is a tool introduced in Nx Witness 4.1 that allows you to see if your system is in good shape and displays information such as the performance of the system and if any errors have occurred. It makes managing smaller and larger systems much easier, in addition to allowing for Nx support engineers to quickly see what's going on when you open a request.
The Health Monitoring tool provides two main pieces of information: metrics and alerts. By viewing and understanding the information provided in each of these sections, you will get a quick and comprehensive view of the system's health.
Metrics are parameters of different components of the System (Servers, cameras, storage, etc.) that can give valuable information about the state of this component. All metrics are aimed at helping investigate problems that could happen during system exploitation. Below are some examples of the parameters you will have access to for each component type:
- System metrics – The number of Servers, camera channels, storage locations, and users, etc.
- Server metrics – CPU/RAM usage, camera channels, server threads, network connections, etc
- Camera metrics – Vendor, model, firmware, video quality settings, etc.
- Storage metrics – Capacity, read/write speed, issues, etc.
- Network Interfaces metrics – IP addresses and i/o rates, etc.
Alerts are representations of metrics that are presented to the user once metrics pass a threshold where they enter into values that should not be reached for that parameter in a healthy system. Alerts can show what's wrong with the system without having to go too far deep in the details. Below are some examples of the alerts you will receive for each component type:
- System alerts – Maximum number of Servers or channels per System reached
- Server alerts – Offline events, high CPU/RAM usage, logging level status, encoding threads > 2, etc.
- Camera alerts – Camera offline event, IP conflict, frame drop, etc.
- Storage alerts – Storage inaccessible or offline, and storage issues in the last 24 hours.
