A clean system monitor and profiler written purely in golang using termui and gopsutil!
Currently compatible with Linux only.
Using go get:
go get -u github.com/pesos/grofer
As an executable:
curl -sSL https://github.com/pesos/grofer/releases/download/<version tag>/grofer --output grofer
chmod +x grofer
For system wide usage, install grofer to a location on $PATH, e.g. /usr/local/bin
mv grofer /usr/local/bin
Building from source:
git clone https://github.com/pesos/grofer
cd grofer
go build grofer.go
grofer is a system profiler written in golang
Usage:
grofer [flags]
grofer [command]
Available Commands:
about about is a command that gives information about the project in a cute way
help Help about any command
proc proc command is used to get per-process information
Flags:
--config string config file (default is $HOME/.grofer.yaml)
-c, --cpuinfo Info about the CPU Load over all CPUs
-h, --help help for grofer
-r, --refresh int32 Overall stats UI refreshes rate in milliseconds greater than 1000 (default 1000)
-t, --toggle Help message for toggle
Use "grofer [command] --help" for more information about a command.
This gives overall utilization stats refreshed every refreshRate milliseconds. Default and minimum value of the refresh rate is 1000 ms.
Information provided:
- CPU utilization per core
- Memory (RAM) usage
- Network usage
- Disk storage
The -c, --cpuinfo flag displays finer details about the CPU load such as percentage of the time spent servicing software interrupts, hardware interrupts, etc.
Information provided:
-
Usr : % of time spent executing user level applications.
-
Sys : % of time spent executing kernel level processes.
-
Irq : % of time spent servicing hardware interrupts.
-
Idle : % of time CPU was idle.
-
Nice : % of time spent by CPU executing user level processes with a nice priority.
-
Iowait: % of time spent by CPU waiting for an outstanding disk I/O.
-
Soft : % of time spent by the CPU servicing software interrupts.
-
Steal : % of time spent in involuntary waiting by logical CPUs.
If the -r flag is specified then the UI will refresh and display new information every refreshRate milliseconds. The minimum and default value for refreshRate is 1000 ms.
This lists all running processes and relevant information.
This gives information specific to a process, specified by a valid PID.
Information provided:
- CPU utilization %
- Memory utilization %
- Child processes
- Number of voluntary and involuntary context switches
- Memory usage (RSS, Data, Stack, Swap)
