@ -35,4 +35,31 @@ Metrics reported are:
- **reads** - The total number of bytes read.
- **writes** - The total number of bytes written.
- **iotime** - Time spent on IO in milliseconds.
- **queue** - Lenght of IO queue.
- **queue** - Lenght of IO queue.
## Process Extension
Reports metrics on one or more running processes.
- **mem_rss** - Resident set memory in bytes.
- **mem_vsz** - Virtual memory in bytes.
- **kernel_time** - Time spent (in milliseconds) in kernel space.
- **user_time** - Time used (in milliseconds) in user space.
- **read_bytes** - Bytes read by process.
- **write_bytes** - Bytes written by process.
- **files** - Files currently open by process.
- **threads** - Running threads.
- **user** - User running the process.
- **group** - Group running the process
- **prio** - Process priority.
### Configuration
The **include** option let's you specify what processes to report for.
```toml
[extension.base_process]
enabled = true # true or false
include = [ "java", "influxd", "grafana-server" ]
