Note ⚠️ No protocol header (e.g., https://, http://). | | Task Name | The name that identifies this monitoring, which must be unique. | | Port | The port provided by Linux SSH, default is 22. | | Timeout | Sets the connection timeout in milliseconds, default is 6000 ms. | | Connection Reuse | Sets whether SSH connections are reused, default is :false. If false, a new connection is created each time information is retrieved. | | Use Proxy Connection | Sets Whether connect via proxy, default is false. | | Username | SSH connection username, optional. | | Password | SSH connection password, optional. | | Collector | Configures which collector is used to schedule data collection for this monitoring. | | Monitoring Period | The interval time for periodic data collection in seconds, with a minimum interval of 30 seconds. | | Binding Tags | Used for categorized management of monitoring resources. | | Description | Additional notes and descriptions for this monitoring, where users can make notes. | | PrivateKey | The private key required to connect to the server. | | PrivateKey PassPhrase | The password phrase used to encrypt the SSH private key. If the private key was generated with a passphrase, this field must be filled to decrypt and use the key for authentication. | | Proxy Host | The address of the proxy server, supporting IPV4, IPV6, or domain name format. Required when using SSH jump host to access the target host. | | Proxy Port | The port number of the proxy service, default is 22. | | Proxy Username | The authentication username required to connect to the proxy server. | | Proxy Username | The authentication password required to connect to the proxy server. | | Proxy PrivateKey | The private key required to authenticate with the proxy server. | ### Data Collection Metrics #### Metric Set: Basic System Information | Metric Name | Metric Unit | Metric Help Description | |-------------|-------------|-------------------------| | hostname | None | Host name | | version | None | System version | | uptime | None | System Uptime | #### Metric Set: CPU Information | Metric Name | Metric Unit | Metric Help Description | |----------------|-------------|-----------------------------------| | info | None | CPU model | | cores | None | Number of CPU cores | | interrupt | None | Number of CPU interrupts | | load | None | Average CPU load (1/5/15 minutes) | | context_switch | None | Number of context switches | | usage | % | CPU usage | #### Metric Set: Memory Information | Metric Name | Metric Unit | Metric Help Description | |-------------|-------------|-------------------------------------| | total | Mb | Total memory capacity | | used | Mb | Memory used by user programs | | free | Mb | Free memory capacity | | buff_cache | Mb | Memory used for cache | | available | Mb | Remaining available memory capacity | | usage | % | Memory usage rate | #### Metric Set: Disk Information | Metric Name | Metric Unit | Metric Help Description | |---------------|-------------|----------------------------------------| | disk_num | None | Total number of disks | | partition_num | None | Total number of partitions | | block_write | None | Total number of blocks written to disk | | block_read | None | Total number of blocks read from disk | | write_rate | iops | Disk block write rate per second | #### Metric Set: Network Card Information | Metric Name | Metric Unit | Metric Help Description | |----------------|-------------|-------------------------------| | interface_name | None | Network card name | | receive_bytes | Byte | Inbound data traffic (bytes) | | transmit_bytes | Byte | Outbound data traffic (bytes) | #### Metric Set: File System | Metric Name | Metric Unit | Metric Help Description | |-------------|-------------|-------------------------| | filesystem | None | Name of the file system | | used | Mb | Used disk size | | available | Mb | Available disk size | | usage | % | Usage rate | | mounted | None | Mount point directory | #### Metric Set: Top 10 CPU Processes Statistics for the top 10 processes using the CPU.
